Background Heavy metal exposure is an emerging environmental risk factor linked to cardiovascular disease (CVD)
through its effects on vascular ageing. However, the relationship between heavy metal exposure and vascular age
have not been fully elucidated.
Methods This cross-sectional study analyzed data from 3,772 participants in the National Health and Nutrition Examination
Survey (NHANES) from 2005 to 2016. We measured urinary concentrations of nine heavy metals and assessed
their associations with vascular age, estimated pulse wave velocity (ePWV) and heart vascular age (HVA). Additionally,
sex-stratified analyses, Weighted Quantile Sum (WQS) regression and Bayesian Kernel Machine Regression were
conducted to explore the effects of individual and mixed metal exposures.
Results Exposure to metals such as cadmium (Cd) cesium (Cs), cobalt (Co), and lead (Pb) was significantly associated
with increased vascular age, with odds ratios (OR) ranging from 1.05 to 3.48 in full adjusted models. Sex-stratified
analyses indicated that individual metal including cobalt (Co) and cadmium (Cd) exposures had a more substantial
impact on males. WQS analysis consistently showed combined heavy metals exposure had stronger associations
with increased vascular age in men (OR for HVA = 3.89, 95% CI 2.91–5.28).
Conclusions This study highlights a significant association between heavy metal exposure and increased vascular
age. Stratified analyses illustrated men might be more susceptible to the combined effects of multiple heavy metal
exposure. The findings underscore the importance of considering sex-specific responses and interventions measures
in cardiovascular risk assessments and managements. Further research is needed to validate these findings
and to develop more precise public health strategies targeting environmental risks

Pulmonary fibrosis is characterized by progressive lung scarring, leading to a decline in lung function and an increase
in morbidity and mortality. This study leverages single-cell sequencing and machine learning to unravel the complex
cellular and molecular mechanisms underlying pulmonary fibrosis, aiming to improve diagnostic accuracy
and uncover potential therapeutic targets. By analyzing lung tissue samples from pulmonary fibrosis patients, we
identified distinct cellular phenotypes and gene expression patterns that contribute to the fibrotic process. Notably,
our findings revealed a significant enrichment of activated B cells, CD4 T cells, macrophages, and specific fibroblast
subpopulations in fibrotic versus normal lung tissue. Machine learning analysis further refined these observations,
resulting in the development of a diagnostic model with enhanced precision, based on key gene signatures including
TMEM52B, PHACTR1, and BLVRB. Comparative analysis with existing diagnostic models demonstrates the superior
accuracy and specificity of our approach. Through In vitro experiments involving the knockdown of PHACTR1,
TMEM52B, and BLVRB genes demonstrated that these genes play crucial roles in inhibiting the expression of α-SMA
and collagen in lung fibroblasts induced by TGF-β. Additionally, knockout of the PHACTR1 gene reduced inflammation
and collagen deposition in a bleomycin-induced mouse model of pulmonary fibrosis in vivo. Additionally, our
study highlights novel gene signatures and immune cell profiles associated with pulmonary fibrosis, offering insights
into potential therapeutic targets. This research underscores the importance of integrating advanced technologies
like single-cell sequencing and machine learning to deepen our understanding of pulmonary fibrosis and pave
the way for personalized therapeutic strategies.

Nowadays, extracellular vesicles (EVs) such as exosomes participate in cell-cell communication and gain attention
as a new approach for cell-free therapies. Recently, various studies have demonstrated the therapeutic ability
of exosomes, while the biological effect of human endometrial stem cell (hEnSC)-derived small EVs such as exosomes
is still unclear. Herein, we obtained small EVs from hEnSC and indicated that these small EVs activate the vital cell
signaling pathway and progress neurite outgrowth in PC-12 cell lines. For this purpose, hEnSC-derived small EVs were
extracted by ultracentrifuge and characterized by DLS, SEM, TEM, and western blot. Also, dil-staining of hEnSC-derived
small EVs was done to determine the penetration of hEnSC-derived small EVs into PC12 cells. The MTT assay, scratch
assay, and western blot assay were applied to PC12 cells that were exposed to different concentrations of small
EVs (0, 50, 100, and 150 μg/ml). Our results demonstrated that small EVs significantly increased neurite outgrowth,
proliferation, and migration in PC12 cells in a dose-dependent manner. Moreover, the analysis of western blots
showed increased expression of the PI3k/AKT signaling pathway in PC12 cells exposed to hEnSC-derived small EVs
in a dose-dependent manner. Also, the results of this study indicated that hEnSC-derived small EVs can enhance cell
proliferation and migration and promote neural outgrowth by activating the PI3k/AKT signaling pathway. Accordingly,
hEnSC-derived small EVs became an effective strategy for cell-free therapies. Altogether, these positive effects make
hEnSC-derived small EVs a new efficient approach in regenerative medicine, especially for the cure of neural injury.

Background: Dysregulated energy metabolism has emerged as a defining hallmark of cancer, particularly evident
in triple-negative breast cancer (TNBC). Distinct from other breast cancer subtypes, TNBC exhibits heightened
glycolysis and aggressiveness. However, the transcriptional mechanisms of aerobic glycolysis in TNBC remains poorly
understood.
Methods: The Cancer Genome Atlas (TCGA) cohort was utilized to identify genes associated with glycolysis. The role
of FOSL1 in glycolysis and tumor growth in TNBC cells was confirmed through both loss-of-function and gain-offunction
experiments. The subcutaneous xenograft model was established to evaluate the therapeutic potential of
targeting FOSL1 in TNBC. Additionally, chromatin immunoprecipitation and luciferase reporter assays were employed
to investigate the transcriptional regulation of glycolytic genes mediated by FOSL1.
Results: FOSL1 is identified as a pivotal glycolysis-related transcription factor in TNBC. Functional verification shows
that FOSL1 enhances the glycolytic metabolism of TNBC cells, as evidenced by glucose uptake, lactate production,
and extracellular acidification rates. Notably, FOSL1 promotes tumor growth in TNBC in a glycolysis-dependent
manner, as inhibiting glycolysis with 2-Deoxy-D-glucose markedly diminishes the oncogenic effects of FOSL1 in TNBC.
Mechanistically, FOSL1 transcriptionally activates the expression of genes such as SLC2A1, ENO1, and LDHA, which
further accelerate the glycolytic flux. Moreover, FOSL1 is highly expressed in doxorubicin (DOX)-resistant TNBC cells
and clinical samples from cases of progressive disease following neoadjuvant chemotherapy. Targeting FOSL1 proves
effective in overcoming chemoresistance in DOX-resistant MDA-MB-231 cells.
Conclusion: In summary, FOSL1 establishes a robust link between aerobic glycolysis and carcinogenesis, positioning
it as a promising therapeutic target, especially in the context of TNBC chemotherapy

Background: Non-Small Cell Lung Cancer (NSCLC) is the leading cause of cancer death worldwide. Although
immune checkpoint inhibitors (ICIs) have shown remarkable clinical efficacy, they can also induce a paradoxical cancer
acceleration, known as hyperprogressive disease (HPD), whose causative mechanisms are still unclear.
Methods: This study investigated the mechanisms of ICI resistance in an HPD-NSCLC model. Two primary cell cultures
were established from samples of a NSCLC patient, before ICI initiation (“baseline”, NSCLC-B) and during HPD (“hyperprogression”,
NSCLC-H). The cell lines were phenotypically and molecularly characterized through immunofluorescence,
Western Blotting and RNA-Seq analysis. To assess cell plasticity and aggressiveness, cellular growth patterns
were evaluated both in vitro and in vivo through 2D and 3D cell growth assays and patient-derived xenografts
establishment. In vitro investigations, including the evaluation of cell sensitivity to interferon-gamma (IFN-γ) and cell
response to PD-L1 modulation, were conducted to explore the influence of these factors on cell plasticity regulation.
Results: NSCLC-H exhibited increased expression of specific CD44 isoforms and a more aggressive phenotype, including
organoid formation ability, compared to NSCLC-B. Plastic changes in NSCLC-H were well described by a deep
transcriptome shift, that also affected IFN-γ–related genes, including PD-L1. IFN-γ–mediated cell growth inhibition
was compromised in both 2D-cultured NSCLC-B and NSCLC-H cells. Further, the cytokine induced a partial activation
of both type I and type II IFN-pathway mediators, together with a striking increase in NSCLC-B growth in 3D cell

Background: Chronic kidney disease (CKD) has emerged as a major health problem worldwide. Previous studies have
shown that specific miRNA expression profiles of patients with CKD are significantly changed. In this study, we aim to
elucidate the role of miRNAs as potential biomarkers in CKD progression by integrating bioinformatics analysis with
experimental validation, thereby providing medical evidence for the prevention and treatment of CKD.
Method: Bioinformatics analysis was used to identify potential targets and pathways in CKD-associated renal fibrosis
through randomly obtaining miRNA microarray data related to CKD patients in the Gene Expression Omnibus (GEO)
database according to the inclusion and exclusion criteria, conducting pathway enrichment analysis and constructing
protein-protein interaction (PPI) networks and miRNA-mRNA network by Cytoscape 3.8.0. In vitro experiments were
employed to verify the role and mechanism of miR-223-3p in human renal tubular epithelial cells (HK2) through
Quantitative real-time PCR assays, Western blot, Immunofluorescence analysis and Double luciferase reporter gene
experiment. Multi-group one-way analysis of variance (ANOVA) and the Dunnett-t test were used to analyze the
results by SPSS24.0.
Results: 10 up-regulated and 11 down-regulated miRNAs of CKD patients were screened out. Phosphatidylinositol
3-kinase/protein kinase B (PI3K/Akt) was the first pathway of pathway enrichment analysis. MiR-223-3p (logFC=
2.047, p = 0.002) was one of the four hub miRNAs. Furthermore, we observed a reduction in α-smooth muscle actin
(α-SMA) (p = 0.001) and Collagen type I alpha 1 (Col1-a1) (p = 0.023) levels upon miR-223-3p overexpression, which
aligned with our bioinformatics predictions. This downregulation was attributed to the inhibition of nuclear factor
kappa-B (NF-κB) nuclear translocation and subsequent decrease in the secretion of inflammatory cytokines, such as
interleukin-6 (IL-6) (p = 0.005). Conversely, when CHUK was further overexpressed, the inhibitory effect of miR-223-3p
on epithelial-mesenchymal transition (EMT) was attenuated, confirming the specific interaction between miR-223-3p
and CHUK

The systematic review was registered on the PROSPERO website (CRD42024558287). Our objective is to
systematically summarise the clinical evidence of glucagon-like peptide-1 receptor agonists (GLP-1 RA) for
obstructive sleep apnea (OSA) in patients with Obesity or/and type 2 Diabetes Mellitus (T2DM). This analysis
was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. 10
databases and registers Web of Science, Scopus, PubMed, APA PsycInfo, Embase, Ovid, Cochrane Library, CINAHL,
Clinicaltrials.gov, and International Clinical Trials Registry Platform (ICTRP) were retrieved from the establishment to
July 14, 2024 for related randomized controlled trials (RCT) and non-RCTs. Data were extracted by two investigators
separately, and only the RCTs were included in the quantitative synthesis. The outcome was operated by Review
Manager 5.4 and Stata 15.0. Ten studies containing eight RCTs and two non-RCTs were included. The efficacy of
the GLP-1 RA group in reducing apnea-hypopnea index (AHI) was superior to that of the control group in patients
with T2DM (MD = -5.68, 95%CI [-7.97, -3.38], P < 0.00001, I2 = 0%). GLP-1 RAs also possessed a tendency to reduce
AHI in patients with obesity but more evidence is needed to support the findings due to the inconsistency. In
consideration of the enhanced metabolic parameters observed with GLP-1 RAs, they may be recommended as
useful hypoglycaemic medication for the management of T2DM with OSA. Patients with obesity and OSA may
consider GLP-1 RA as a potential treatment option if the adverse events are deemed tolerable.

The epithelial-mesenchymal transition (EMT) is a critical process in cancer progression, facilitating tumor cells
to develop invasive traits and augmenting their migratory capabilities. EMT is primed by tumor microenvironment
(TME)-derived signals, whereupon cancer cells undergoing EMT in turn remodel the TME, thereby modulating tumor
progression and therapeutic response. This review discusses the mechanisms by which EMT coordinates TME dynam
ics, including secretion of soluble factors, direct cell contact, release of exosomes and enzymes, as well as metabolic
reprogramming. Recent evidence also indicates that cells undergoing EMT may differentiate into cancer-associated
f
ibroblasts, thereby establishing themselves as functional constituents of the TME. Elucidating the relationship
between EMT and the TME offers novel perspectives for therapeutic strategies to enhance cancer treatment effi
cacy. Although EMT-directed therapies present significant therapeutic potential, the current lack of effective target
ing approaches—attributable to EMT complexity and its microenvironmental context dependency—underscores
the necessity for mechanistic investigations and translational clinical validation.

Background: Esophageal squamous cell carcinoma (ESCC) is a serious invasive malignancy with an ambiguous
etiology. Evidence indicates that circular RNA (circRNA) is significantly involved in the regulatory processes associated with cancer development. Nevertheless, the specific molecular mechanisms through which circRNA facilitates
the progression of ESCC are still largely undefined.
Methods: Here, we identified that the expression of hsa_circ_0007580 (designated circPRKCA) was markedly elevated
in ESCC. Fluorescence in situ hybridization (FISH) was conducted to verify the expression, intracellular localization,
and potential prognostic value of circPRKCA based on the tissue microarray. Gain- and loss-of-function assays were
employed to investigate the effects of circPRKCA both in vitro and in vivo. RNA pull-down and mass spectrometry
(MS) were performed to identify the proteins bound to circPRKCA. mRNA sequencing was conducted to screen
the downstream target genes of circPRKCA. Furthermore, immunoprecipitation and methylated RNA immunoprecipitation (MeRIP) analysis were used to explore the regulatory mechanisms.
Results: We found that circPRKCA exhibited significant upregulation in ESCC tissues and correlated with unfavorable
prognostic outcomes. Biological function experiments further confirmed that circPRKCA enhances the capabilities
of migration, invasion, and angiogenesis in ESCC. Mechanistically, circPRKCA engages in interaction with Y-box binding protein 1 (YBX1) within the cytoplasmic milieu, consequently preventing the ubiquitination-mediated degradation of YBX1. Increased concentrations of YBX1 increase the stability of granulocyte–macrophage colony-stimulating
factor (CSF2) mRNA in a 5-methylcytosine (m5C)-dependent manner. This process facilitates metastasis in ESCC.
Conclusion: In this research, we identified a correlation between circPRKCA and unfavorable prognoses in patients
with ESCC. It is instrumental in the metastatic progression of ESCC via the YBX1/CSF2 signaling pathway. Consequently, targeting circPRKCA may represent a promising therapeutic strategy for ESCC

Background: Chimeric antigen receptor T (CAR-T) cell therapy holds promise for cancer treatment, but its efficacy
is often hindered by metabolic constraints in the tumor microenvironment. This study investigates the role of glutamine in enhancing CAR-T cell function against ovarian cancer.
Methods: Metabolomic profiling of blood samples from ovarian cancer patients treated with MSLN-CAR-T cells
was conducted to identify metabolic changes. In vitro, glutamine pretreatment was applied to CAR-T cells, and their
proliferation, CAR expression, tumor lysis, and cytokine production (TNF-α, IFN-γ) were assessed. Mechanistic studies focused on the mTOR-SREBP2 pathway and its effect on HMGCS1 expression, membrane stability and immune
synapse formation. In vivo, the antitumor effects and memory phenotype of glutamine-pretreated CAR-T cells were
evaluated.
Results: Elevated glutamine levels were observed in the blood of ovarian cancer patients who responded to MSLN-CAR-T cell treatment. Glutamine pretreatment enhanced CAR-T cell proliferation, CAR expression, tumor lysis,
and cytokine production. Mechanistically, glutamine activated the mTOR-SREBP2 pathway, upregulating HMGCS1
and promoting membrane stability and immune synapse formation. In vivo, glutamine-pretreated CAR-T cells exhibited superior tumor infiltration, sustained antitumor activity, and preserved memory subsets.
Conclusions: Our findings highlight glutamine-driven metabolic rewiring via the mTOR-SREBP2-HMGCS1 axis
as a strategy to augment CAR-T cell efficacy in ovarian cancer.

Background: Alterations in both oral and gut microbiota have been identified in children with autism spectrum
disorder (ASD), but the interaction between these microbiota and their potential to predict outcomes of fecal
microbiota transplantation (FMT) remain poorly understood.
Methods: This study investigated the structure and function of the tongue-coating microbiota in children with ASD
and explored its correlation with ASD symptoms and gut microbiota. Germ-free ASD mice, colonized with healthy gut
microbiota, and children with ASD treated with washed microbiota transplantation (WMT) were assessed for changes
in autism symptoms and microbiota composition. Predictive models were also developed based on pre-treatment
tongue-coating microbiota and clinical features to forecast WMT outcomes.
Results: Significant alterations were detected in the tongue-coating microbiota of children with ASD, with several
bacterial species showing associations with ASD symptoms and gut microbiota composition. Following WMT, both
mice and children exhibited substantial improvements in autism-related behaviors, alongside marked shifts in
their gut and tongue-coating microbiota. A significant decrease in Haemophilus in the tongue-coating microbiota,
which positively correlated with ASD severity, was observed. Additionally, a reduction in chemoheterotrophic and
fermentation functions in the tongue-coating microbiota was identified. Predictive models utilizing pre-treatment
tongue-coating microbiota and clinical data demonstrated comparable accuracy to those based on gut microbiota
for forecasting WMT outcomes.
Conclusions: These findings highlight a significant interaction between gut and tongue-coating microbiota in ASD,
which may play a pivotal role in treatment outcomes. Predictive models integrating pre-treatment microbiota and
clinical features could improve precision treatment strategies for children with ASD undergoing WMT.

Background: Doxorubicin (Dox) resistance remains a significant challenge in osteosarcoma (OS) treatment, limiting
its therapeutic efficacy and contributing to poor clinical outcomes. This study aims to investigate the use of iRGD
modified biomimetic nanoparticles (NPs) for the targeted delivery of METTL3-specific inhibitors, addressing Dox
resistance by regulating the m6A modification of MCAM.
Methods: Biomimetic NPs were fabricated by fusing OS cell membranes with lipid NPs, followed by iRGD peptide
modification to enhance tumor targeting capability. These NPs were loaded with the METTL3 inhibitor STM2457
and characterized for stability, drug encapsulation efficiency, and cellular uptake by Dox-resistant OS cells. Functional
assays were implemented to examine their impact on cell biological functions in vitro. Therapeutic efficacy was further validated utilizing a mouse xenograft model to monitor tumor progression and metastatic behavior.
Results: The iRGD-modified NPs exhibited excellent stability, high drug encapsulation efficiency, and significantly
improved cellular uptake in vitro. METTL3 inhibition reduced MCAM m6A modification, leading to decreased proliferation and invasion of Dox-resistant OS cells. In vivo, the combination of Dox and METTL3-loaded NPs significantly
inhibited tumor growth and lung metastasis in the mouse model.
Conclusions: iRGD-modified biomimetic NPs offer a promising approach to overcoming Dox resistance in OS
by targeting the METTL3-MCAM axis. This strategy may improve therapeutic outcomes and holds potential for clinical
application in resistant cancers.

Background: Head and neck cancer (HNC) presents significant research challenges due to the complexity of its
tumor microenvironment (TME) and the heterogeneity across different cancer subtypes. Recent advancements in
three-dimensional (3D) culture models and organ-on-a-chip (OOC) technology offer new avenues for mimicking the
TME and enhancing the study of tumor biology, drug responses, and personalized treatment strategies. This study
aims to summarize the current state of these models in HNC research and their potential in bridging the gap between
preclinical models and clinical applications.
Methods: This review synthesizes findings from recent literature on the use of 3D models such as tumor spheroids,
organoids, and co-culture systems in HNC research. A focus is placed on their applications in different cancer types,
including laryngeal, oral, and nasopharyngeal cancers. Additionally, the integration of OOC technology in studying
cancer metastasis, immunotherapy, and radiotherapy is discussed. Relevant studies on the role of AI and robotics in
improving model efficiency and scalability are also examined.
Results: The review identifies key developments in 3D model systems and OOC technologies, highlighting their
ability to replicate patient-specific tumor behaviors and predict therapeutic responses. While these models have
advanced the understanding of HNC pathophysiology, challenges remain in terms of technical limitations, validation,
and physiological relevance. The integration of AI and robotics has shown promise in enhancing the scalability and
data analysis capabilities of these models.
Conclusions: Advancements in 3D and OOC technologies are essential for overcoming the current limitations in
HNC research. These models offer valuable insights into tumor biology and therapeutic efficacy, and their integration

Background: Non-communicable diseases (NCDs) are a major global health and economic burden. Precision
medicine has merged as a promising approach for treating NCDs by tailoring health interventions to individual
profiles. Despite rapid advances, its effective implementation remains slow. This systematic review aimed to examine
the implementation landscape for delivering precision medicine interventions, services, or programs for NCDs,
focusing on barriers, facilitators, strategies, and outcomes.
Methods: Comprehensive searches were performed in PubMed, Embase, CINAHL, and Web of Science until
November 2024. The search strategy comprised of four key concepts, i.e. precision medicine, NCDs, implementation,
and public health. Articles published from 2014 onwards were included. Extracted data included study characteristics,
populations, precision medicine intervention details, and information related to implementation. Relevant data were
coded to implementation science frameworks and taxonomies. These included the updated Consolidated Framework
for Implementation Research (CFIR 2.0), Expert Recommendations for Implementing Change (ERIC), and Proctor’s
outcomes framework. The QuADs tool was used to assess the risk of bias of included studies.
Results: A total of 10,039 records were identified, with 8,684 abstracts and 463 full texts screened. Of these, 68
studies met the inclusion criteria. While 64 studies reported implementation determinants [i.e. barriers (n = 61) and/
or facilitators (n = 40)], approximately two-thirds proposed or implemented strategies that were primarily based on
intuition. Key barriers identified included ‘access to knowledge and information’ (n = 34) and ‘work infrastructure’
(n = 21) within the Inner Setting, and ‘financing’ (n = 20) within the Outer Setting. While financial burdens were clearly
attributed to patients and healthcare settings, there was less clarity and strategic direction regarding potential
funding sources to support implementation strategies. Implementation Outcomes were reported in 46 instances,

Background: The microbiota-gut-brain (MGB) axis is implicated in Alzheimer’s disease (AD), but evidence for
interventional strategies targeting this axis remains limited.
Methods In a 24-week, single-blind, randomized controlled trial, 84 individuals with mild cognitive impairment (MCI)
or mild AD received either computerized cognitive training (CCT) or treatment as usual (TAU). Alzheimer’s Disease
Assessment Scale-cognitive subscale (ADAS-cog) was the primary outcome. We also assessed functional connectivity
(fNIRS), plasma trimethylamine N-oxide (TMAO) levels, and gut microbiota at baseline and 24 weeks.
Results: Seventy-four participants completed the study. The CCT group showed significant improvement in ADAS
cog scores compared to controls (Cohen’s d = 1.57 by week 24). Notably, CCT also induced a distinct reorganization of
prefrontal functional connectivity and significantly reduced plasma TMAO levels. Microbiome analysis revealed that
CCT mitigated the expansion of Ruminococcus torques group (R.torques), which was observed in the control group.
Crucially, R.torques was the only genus significantly correlated with improvements in cognition (ADAS-cog, r = 0.407),
neuropsychiatric symptoms (NPI, r = 0.395), TMAO reduction (r = 0.443), and functional connectivity changes (r = 0.449).
Conclusion: A 24-week CCT program improves cognitive function in MCI and mild AD, potentially through
downregulating the R.torques-TMAO pathway within the MGB axis. This pathway represents a promising novel target
for multi-domain intervention in AD.

Background: Ischemic stroke (IS) ranks as the leading cause of disability and the second cause of mortality in adults
worldwide. This investigation aimed to describe the fingerprint of immunoglobulin G (IgG) N-glycans and feature
of circulating inflammatory cytokines that were associated with the progression of IS, as well as to screen potential
biomarkers for screening individuals at higher IS risk.
Methods: A prospective cohort, Liaocheng City Stroke Risk Cohort (LCSRC), was launched in December 2014,
in which 1,599 healthy participants were enrolled from Liaocheng People’s Hospital (LPH). During nine years of
follow-up, 67 participants who were diagnosed with IS were enrolled in the case group. Meanwhile, 201 individuals
who did not develop IS were randomly selected as the controls. The hydrophilic interaction chromatography based
on ultra-performance liquid chromatography (HILIC-UPLC) was utilized to detect the IgG N-glycans profiles in serum.
A prediction model for the occurrence of IS was constructed using a logistic regression.
Results: The levels of GP1, GP2, GP3, GP4, GP6, GP7, GP11, GP13, GP19 and GP24 were considerably higher in the IS
group compared with the controls, whereas GP5, GP8, GP14 and GP18 were lower among the IS cases. In addition,
compared to the controls, the IS patients had substantially higher levels of matrix metalloproteinase-9 (MMP-9),
tumor necrosis factor-α (TNF-α), and high-sensitivity C-reactive protein (hs-CRP). In terms of four major features of IgG
N-glycosylation, a high level of fucosylation, monogalactosylation, and digalactosylation was significantly associated
with a decreased risk for IS occurrence. Moreover, the glycosylation-based prediction model was of promising
capability to predict IS risk with an area under the curve (AUC) of 0.756 (95%CI: 0.696 to 0.815).

Recent advances in single-cell multi-omics technologies have revolutionized cellular analysis, enabling
comprehensive exploration of cellular heterogeneity, developmental trajectories, and disease mechanisms at
unprecedented resolution. Foundation models, originally developed for natural language processing, are now
driving transformative approaches to high-dimensional, multimodal single-cell data analysis. Frameworks such
as scGPT and scPlantFormer excel in cross-species cell annotation, in silico perturbation modeling, and gene
regulatory network inference. Multimodal integration approaches, including pathology-aligned embeddings and
tensor-based fusion, harmonize transcriptomic, epigenomic, proteomic, and spatial imaging data to delineate
multilayered regulatory networks across biological scales. Federated computational platforms facilitate decentralized
data analysis and standardized, reproducible workflows, fostering global collaboration. Challenges persist, including
technical variability across platforms, limited model interpretability, and gaps in translating computational insights
into clinical applications. Overcoming these hurdles demands standardized benchmarking, multimodal knowledge
graphs, and collaborative frameworks that integrate artificial intelligence with human expertise. This review
synthesizes recent technological advancements and proposes actionable strategies to bridge single-cell multi-omics innovations with mechanistic biology and precision medicine.

Background: Osteosarcoma (OS) is a prevalent malignant bone cancer in children and adolescents, yet the
mechanisms driving its progression and therapeutic resistance remain inadequately understood. Current treatment
modalities often overlook the significance of the “cold–heat” imbalance as conceptualized in traditional Chinese
medicine (TCM), highlighting a critical gap in integrating TCM principles with modern cancer therapies.
Objectives: We aimed to investigate the therapeutic effects of capsaicin (CAP) on the “cold–heat” imbalance in OS
model mice and elucidate the mechanisms involved by utilizing a multi-omics approach.
Methods: We employed metabolomics, transcriptomics, and network pharmacology to analyze the impact of CAP
on OS progression. Tumor-bearing mice were treated with CAP, and metabolic profiles, tumor volumes, and key
molecular targets were assessed.
Results: Our findings revealed that CAP significantly shifted the metabolic phenotype of OS model mice from a “cold”
state to a “heat” state, resulting in a reduced tumor volume and increased metabolic activity. Notably, CAP was shown
to target key pathways involving AKT1, STAT3, NF-κB, EGFR and Caspase 3.
Conclusion: CAP effectively modulated tumor growth and restored the “cold–heat” balance in OS model mice,
providing valuable insights into the potential integration of TCM with conventional oncologic therapies. These
findings underscore the importance of multifaceted strategies in developing innovative cancer treatments and
contribute to the advancement of translational medicine.

Background: A better diagnostic marker is in need to distinguish breast cancer from suspicious breast lesions. The
abnormal glycosylation of haptoglobin has been documented to assist cancer diagnosis. This study aims to evaluate
disease-specific haptoglobin (DSHp)-β N-glycosylation as a potential biomarker for breast cancer diagnosis.
Methods: DSHp-β chains of 497 patients with suspicious breast lesions who underwent breast surgery were separated from serum immunoinflammatory-related protein complexes. DSHp-β N-glycosylation was quantified by mass
spectrometric analysis. After missing data imputation and propensity score matching, patients were randomly
assigned to the training set (n = 269) and validation set (n = 113). Logistic regression analysis was employed in model
and nomogram construction. The diagnostic performance was analyzed with receiver operating characteristic
and calibration curves.
Results: 95 N-glycopeptides at glycosylation sites N207/N211, N241, and N184 were identified in 235 patients
with benign breast diseases and 262 patients with breast cancer. DSHp-β N-tetrafucosyl and hexafucosyl were significantly increased in breast cancer compared with benign diseases (p < 0.001 and p = 0.001, respectively). The new diagnostic model and nomogram included GN2F2, G6N3F6, GN2FS at N184, G-N&G2S2, G2&G3NFS, G2N3F, GN3 at N207/
N211, CEA, CA153, and could reliably distinguish breast cancer from benign diseases. For the training set, validation
set, and training and validation sets, the area under the curves (AUCs) were 0.80 (95% CI: 0.75–0.86, specificity: 87%,
sensitivity: 62%), 0.77 (95% CI:0.69–0.86, specificity: 75%, sensitivity: 69%), and 0.80 (95% CI:0.76–0.84, specificity: 77%,
sensitivity: 68%), respectively. CEA, CA153, and their combination yielded AUCs of 0.62 (95% CI: 0.56–0.67, specificity:
29%, sensitivity: 90%), 0.65 (95% CI: 0.60–0.71, specificity: 74%, sensitivity: 51%), and 0.67 (95% CI: 0.62–0.73, specificity:
60%, sensitivity: 68%), respectively.

Background: Psoriasis is a chronic immune-mediated skin condition. Although biologic treatments are effective
in controlling psoriasis, some patients do not respond or lose response to these therapies. Thus, new strategies
for psoriasis treatment are still urgently needed. Double-negative T cells (DNT) play a significant immunoregulatory
role in autoimmune diseases. In this study, we aimed to evaluate the protective effect of DNT in psoriasis and explore
the underlying mechanism.
Methods We conducted a single adoptive transfer of DNT into an imiquimod (IMQ)-induced psoriasis mouse model
through tail vein injection. The skin inflammation and IL-17A producing γδ T cells were evaluated.
Results: DNT administration significantly reduced the inflammatory response in mouse skin, characterized
by decreased skin folds, scales, and red patches. After DNT treatment, the secretion of IL-17A by RORc+ γδlow T cells
in the skin was selectively suppressed, resulting in an amelioration of skin inflammation. Transcriptomic data suggested heightened expression of NKG2D ligands in γδlow T cells within the mouse model of psoriasis induced
by IMQ. When blocking the NKG2D ligand and NKG2D (expressed by DNT) interaction, the cytotoxic efficacy of DNT
against RORc+IL17A+ γδlow T cells was attenuated. Using Ccr5−/− DNT for treatment yielded evidence that DNT
migrates into inflamed skin tissue and fails to protect IMQ-induced skin lesions.
Conclusions: DNT could migrate to inflamed skin tissue through CCR5, selectively inhibit IL-17-producing γδlow T cells
and finally ameliorate mouse psoriasis. Our study provides feasibility for using immune cell therapy for the prevention
and treatment of psoriasis in the clinic.

Background: Regulatory T cells (Tregs) are crucial in maintaining immune homeostasis and preventing autoimmunity and inflammation. A proportion of Treg cells can lose Foxp3 expression and become unstable under inflammation
conditions. The precise mechanisms underlying this phenomenon remain unclear.
Methods: The PI16 gene knockout mice (PI16fl/flFoxp3Cre) in Treg were constructed, and the genotypes were identified. The proportion and phenotypic differences of immune cells in 8-week-old mice were detected by cell counter
and flow cytometry. Two groups of mouse Naïve CD4+T cells were induced to differentiate into iTreg cells to observe
the effect of PI16 on the differentiation and proliferation of iTreg cells, CD4+CD25+Treg and CD4+CD25− effector T cells
(Teff) were selected and co-cultured with antigen presenting cells (APC) to observe the effect of PI16 on the inhibitory ability of Treg cells in vitro. The effects of directed knockout of PI16 in Treg cells on inflammatory symptoms, histopathological changes and immune cell expression in mice with enteritis and autoimmune arthritis were observed
by constructing the model of antigen-induced arthritis (AIA) and colitis induced by dextran sulfate sodium salt (DSS).
Results: We identified peptidase inhibitor 16 (PI16) as a negative regulator of Treg cells. Our findings demonstrate
that conditional knock-out of PI16 in Tregs significantly enhances their differentiation and suppressive functions. The
conditional knockout of the PI16 gene resulted in a significantly higher abundance of Foxp3 expression (35.12 ± 5.71%
vs. 20.00 ± 1.61%, p = 0.034) in iTreg cells induced in vitro compared to wild-type mice. Mice with Treg cell-specific PI16
ablation are protected from autoimmune arthritis (AIA) and dextran sulfate sodium (DSS)-induced colitis development. The AIA model of PI16CKO is characterized by the reduction of joint structure and the attenuation of synovial
inflammation and in DSS-induced colitis model, conditional knockout of the PI16 reduce intestinal structural damage.
Additionally, we found that the deletion of the PI16 gene in Treg can increase the proportion of Treg (1.46 ± 0.14% vs.
0.64 ± 0.07%, p < 0.0001) and decrease the proportion of Th17 (1.00 ± 0.12% vs. 3.84 ± 0.64%, p = 0.001). This change
will enhance the shift of Th17/Treg toward Treg cells in AIA arthritis model (0.71 ± 0.06% vs. 8.07 ± 1.98%, p = 0.003).
In DSS-induced colitis model of PI16CKO, the proportion of Treg in spleen was significantly increased (1.40 ± 0.15%

Background: Lung adenocarcinoma (LUAD) is the predominant histological subtype of lung cancer and the leading
cause of cancer-related mortality. Identifying effective drug targets is crucial for advancing LUAD treatment strategies.
Methods: This study employed proteome-wide Mendelian randomization (MR) and colocalization analyses. We
collected data on 1394 plasma proteins from a protein quantitative trait loci (pQTL) study involving 4907 individuals.
Genetic associations with LUAD were derived from the Transdisciplinary Research in Cancer of the Lung (TRICL) study,
including 11,245 cases and 54,619 controls. We integrated pQTL and LUAD genome-wide association studies (GWASs)
data to identify candidate proteins. MR utilizes single nucleotide polymorphisms (SNPs) as genetic instruments to estimate the causal effect of exposure on outcome, while Bayesian colocalization analysis determines the probability
of shared causal genetic variants between traits. Our study applied these methods to assess causality between plasma
proteins and LUAD. Furthermore, we employed a two-step MR to quantify the proportion of risk factors mediated
by proteins on LUAD. Finally, protein–protein interaction (PPI) analysis elucidated potential links between proteins
and current LUAD medications.
Results: We identified nine plasma proteins significantly associated with LUAD. Increased levels of ALAD, FLT1, ICAM5,
and VWC2 exhibited protective effects, with odds ratios of 0.79 (95% CI 0.72–0.87), 0.39 (95% CI 0.28–0.55), 0.91 (95%
CI 0.72–0.87), and 0.85 (95% CI 0.79–0.92), respectively. Conversely, MDGA2 (OR, 1.13; 95% CI 1.08–1.19), NTM (OR,
1.12; 95% CI 1.09–1.16), PMM2 (OR, 1.35; 95% CI 1.18–1.53), RNASET2 (OR, 1.15; 95% CI 1.08–1.21), and TFPI (OR, 4.58;
95% CI 3.02–6.94) increased LUAD risk. Notably, none of the nine proteins showed evidence of reverse causality.
Bayesian colocalization indicated that RNASET2, TFPI, and VWC2 shared the same variant with LUAD. Furthermore,
NTM and FLT1 demonstrated interactions with targets of current LUAD medications. Additionally, FLT1 and TFPI are
currently under evaluation as therapeutic targets, while NTM, RNASET2, and VWC2 are potentially druggable. These
findings shed light on LUAD pathogenesis, highlighting the tumor-promoting effects of RNASET2, TFPI, and NTM,
along with the protective effects of VWC2 and FLT1, providing a significant biological foundation for future LUAD
therapeutic targets.
Conclusions: Our proteome-wide MR analysis highlighted RNASET2, TFPI, VWC2, NTM, and FLT1 as potential drug
targets for further clinical investigation in LUAD. However, the specific mechanisms by which these proteins influence

Background: Immune checkpoint inhibitors (ICIs), administered alone or combined with chemotherapy, are
the standard of care in advanced non-oncogene addicted Non-Small Cell Lung Cancer (NSCLC). Despite these treatments’ success, most long-term survival benefit is restricted to approximately 20% of patients, highlighting the need
to identify novel biomarkers to optimize treatment strategies. In several solid tumors, immune soluble factors, the activatory CD137+ Tcells, and the immunosuppressive cell subsets Tregs and MDSCs (PMN(Lox1+)-MDSC and M-MDSCs)
correlated with responses to ICIs and clinical outcomes thus becoming appealing predictive and prognostic factors.
This study investigated the role of distinct CD137+ Tcell subsets, Tregs, MDSCs, and immune-soluble factors in NSCLC
patients as possible biomarkers.
Methods: The levels of T cells, MDSCs and soluble factors were evaluated in 89 metastatic NSCLC patients who
underwent ICIs as first- or second-line treatment. T cell analysis was performed by cytoflurimetry evaluating Tregs
and different CD137+ Tcell subsets also combined with CD3+, CD8+, PD1+, and Ki67+ markers. Circulating cytokines
and immune checkpoints were also evaluated by Luminex analysis. All these parameters were correlated with several
clinical factors (age, sex, smoking status, PS and TPS), response to therapy, PFS , and OS . The analyses were conducted
in the overall population and in patients treated with ICIs as first-line (naïve patients).
Results: In both groups of patients, high levels of circulating CD137+ and CD137+PD1+ T cells (total, CD4 and CD8)
and the soluble factor LAG3 positively correlated with response to therapy. In naïve patients, PMN(Lox1+)-MDSCs negatively correlated with clinical response, and a high percentage of Tregs was associated with favorable survival. Moreover, the balance between Treg/CD137+ Tcells or PMN(Lox1+)-MDSC/CD137+ Tcells was higher in non-responding

Background: Urothelial carcinoma (UC) is the second most common urological malignancy. Despite numerous
molecular markers have been evaluated during the past decades, no urothelial markers for diagnosis and recurrence
monitoring have shown consistent clinical utility.
Methods: The methylation level of tissue samples from public database and clinical collected were analyzed. Patients
with UC and benign diseases of the urinary system (BUD) were enrolled to establish TAGMe (TAG of Methylation)
assessment in a training cohort (n = 567) using restriction enzyme-based bisulfite-free qPCR. The performance
of TAGMe assessment was further verified in the validation cohort (n = 198). Urine samples from 57 UC patients
undergoing postoperative surveillance were collected monthly for six months after surgery to assess the TAGMe
methylation.
Results: We identified TAGMe as a potentially novel Universal-Cancer-Only Methylation (UCOM) marker was hypermethylated in multi-type cancers and investigated its application in UC. Restriction enzyme-based bisulfite-free qPCR
was used for detection, and the results of which were consistent with gold standard pyrosequencing. Importantly,
hypermethylated TAGMe showed excellent sensitivity of 88.9% (95% CI: 81.4–94.1%) and specificity of 90.0% (95% CI:
81.9–95.3%) in efficiently distinguishing UC from BUD patients in urine and also performed well in different clinical
scenarios of UC. Moreover, the abnormality of TAGMe as an indicator of recurrence might precede clinical recurrence
by three months to one year, which provided an invaluable time window for timely and effective intervention to prevent UC upstaging

Sustained injury from factors such as hypoxia, infection, or physical damage may provoke improper tissue repair
and the anomalous deposition of connective tissue that causes fibrosis. This phenomenon may take place in any
organ, ultimately leading to their dysfunction and eventual failure. Tissue fibrosis has also been found to be central
in both the process of carcinogenesis and cancer progression. Thus, its prompt diagnosis and regular monitoring
is necessary for implementing effective disease‑modifying interventions aiming to reduce mortality and improve
overall quality of life. While significant research has been conducted on these subjects, a comprehensive
understanding of how their relationship manifests through modern imaging techniques remains to be established.
This work intends to provide a comprehensive overview of imaging technologies relevant to the detection of fibrosis
affecting thoracic organs as well as to explore potential future advancements in this field.

Clear cell renal cell carcinoma (ccRCC) is a prevalent malignancy with complex heterogeneity within epithelial
cells, which plays a crucial role in tumor progression and immune regulation. Yet, the clinical importance of the
malignant epithelial cell-related genes (MECRGs) in ccRCC remains insufficiently understood. This research aims to
undertake a comprehensive investigation into the functions and clinical relevance of malignant epithelial cellrelated genes in ccRCC, providing valuable understanding of the molecular mechanisms and offering potential
targets for treatment strategies. Using data from single-cell sequencing, we successfully identified 219 MECRGs and
established a prognostic model MECRGS (MECRGs’ signature) by synergistically analyzing 101 machine-learning
models using 10 different algorithms. Remarkably, the MECRGS demonstrated superior predictive performance
compared to traditional clinical features and 92 previously published signatures across six cohorts, showcasing its
independence and accuracy. Upon stratifying patients into high- and low-MECRGS subgroups using the specified
cut-off threshold, we noted that patients with elevated MECRGS scores displayed characteristics of an immune
suppressive tumor microenvironment (TME) and showed worse outcomes after immunotherapy. Additionally,
we discovered a distinct ccRCC tumor cell subtype characterized by the high expressions of PLOD2 (procollagenlysine,2-oxoglutarate 5-dioxygenase 2) and SAA1 (Serum Amyloid A1), which we further validated in the Renji tissue
microarray (TMA) cohort. Lastly, ‘Cellchat’ revealed potential crosstalk patterns between these cells and other cell
types, indicating their potential role in recruiting CD163 + macrophages and regulatory T cells (Tregs), thereby

The application of graphene-based nanocomposites for therapeutic and diagnostic reasons has advanced
considerably in recent years due to advancements in the synthesis and design of graphene-based nanocomposites,
giving rise to a new field of nano-cancer diagnosis and treatment. Nano-graphene is being utilized more often
in the field of cancer therapy, where it is employed in conjunction with diagnostics and treatment to address
the complex clinical obstacles and problems associated with this life-threatening illness. When compared to
other nanomaterials, graphene derivatives stand out due to their remarkable structural, mechanical, electrical,
optical, and thermal capabilities. The high specific surface area of these materials makes them useful as carriers in
controlled release systems that respond to external stimuli; these compounds include drugs and biomolecules like
nucleic acid sequences (DNA and RNA). Furthermore, the presence of distinctive sheet-like nanostructures and the
capacity for photothermal conversion have rendered graphene-based nanocomposites highly favorable for optical
therapeutic applications, including photothermal treatment (PTT), photodynamic therapy (PDT), and theranostics.
This review highlights the current state and benefits of using graphene-based nanocomposites in cancer diagnosis
and therapy and discusses the obstacles and prospects of their future development. Then we focus on graphene-based nanocomposites applications in cancer treatment, including smart drug delivery systems, PTT, and PDT.
Lastly, the biocompatibility of graphene-based nanocomposites is also discussed to provide a unique overview of
the topic.

Single-cell technology depicts integrated tumor profiles including both tumor cells and tumor microenvironments,
which theoretically enables more robust diagnosis than traditional diagnostic standards based on only pathology.
However, the inherent challenges of single-cell RNA sequencing (scRNA-seq) data, such as high dimensionality, low
signal-to-noise ratio (SNR), sparse and non-Euclidean nature, pose significant obstacles for traditional diagnostic
approaches. The diagnostic value of single-cell technology has been largely unexplored despite the potential
advantages. Here, we present a graph neural network-based framework tailored for molecular diagnosis of
primary liver tumors using scRNA-seq data. Our approach capitalizes on the biological plausibility inherent in the
intercellular communication networks within tumor samples. By integrating pathway activation features within
cell clusters and modeling unidirectional inter-cellular communication, we achieve robust discrimination between
malignant tumors (including hepatocellular carcinoma, HCC, and intrahepatic cholangiocarcinoma, iCCA) and
benign tumors (focal nodular hyperplasia, FNH) by scRNA data of all tissue cells and immunocytes only. The efficacy
to distinguish iCCA from HCC was further validated on public datasets. Through extending the application of high-throughput scRNA-seq data into diagnosis approaches focusing on integrated tumor microenvironment profiles
rather than a few tumor markers, this framework also sheds light on minimal-invasive diagnostic methods based on
migrating/circulating immunocytes.

Background: Radiation-induced liver fibrosis (RILF) is a common manifestation of radiation-induced liver injury (RILI)
and is caused primarily by activated hepatic stellate cells (HSCs). Circular RNAs (circRNAs) play critical roles in various
diseases, but little is known about the function and mechanism of circRNAs in RILF.
Methods: RNA pull-down and liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to screen
binding proteins of hsa_circ_0096498 (circ96498). RNA-binding protein immunoprecipitation, RNA pull-down
and nuclear and cytoplasmic protein extraction were conducted to confirm the interaction between circ96498
and eukaryotic initiation factor 4A3 (EIF4A3). RNA sequencing was performed to screen target genes regulated by
EIF4A3. HSCs with altered circ96498 and cell division cycle 42 (CDC42) expression were used to assess irradiated HSC
activation. Circ96498 inhibition and CDC42 blockade were evaluated in RILF mouse models.
Results: In this study, we identified a radiation-sensitive circ96498, which was highly expressed in the irradiated
HSCs of paracancerous tissues from RILI patients. Circ96498 inhibited the proliferation but promoted the apoptosis
of irradiated HSCs, suppressed the secretion of proinflammatory cytokines IL-1β, IL-6 and TNF-α, and decreased the
expression of profibrotic markers (α-SMA and collagen 1) in irradiated HSCs. Mechanistically, irradiation induced the
transport of EIF4A3 into the nucleus, and nuclear EIF4A3 increased the stability of CDC42 mRNA and increased CDC42
expression, thereby promoting HSC activation through the NF-κB and JNK/Smad2 pathways. However, the binding
of circ96498 to EIF4A3 impeded the translocation of EIF4A3 into the nucleus, resulting in the inhibition of CDC42
expression and subsequent HSC activation. Furthermore, circ96498 knockdown promoted the development of the

Background: Specific food preferences can determine an individual’s dietary patterns and therefore, may be
associated with certain health risks and benefits.
Methods: Using food preference questionnaire (FPQ) data from a subset comprising over 180,000 UK Biobank
participants, we employed Latent Profile Analysis (LPA) approach to identify the main patterns or profiles
among participants. blood biochemistry across groups/profiles was compared using the non-parametric Kruskal-Wallis test. We applied the Limma algorithm for differential abundance analysis on 168 metabolites and 2923
proteins, and utilized the Database for Annotation, Visualization and Integrated Discovery (DAVID) to identify enriched
biological processes and pathways. Relative risks (RR) were calculated for chronic diseases and mental conditions
per group, adjusting for sociodemographic factors.
Results: Based on their food preferences, three profiles were termed: the putative Health-conscious group (low
preference for animal-based or sweet foods, and high preference for vegetables and fruits), the Omnivore group
(high preference for all foods), and the putative Sweet-tooth group (high preference for sweet foods and sweetened
beverages). The Health-conscious group exhibited lower risk of heart failure (RR = 0.86, 95%CI 0.79–0.93) and chronic
kidney disease (RR = 0.69, 95%CI 0.65–0.74) compared to the two other groups. The Sweet-tooth group had greater
risk of depression (RR = 1.27, 95%CI 1.21–1.34), diabetes (RR = 1.15, 95%CI 1.01–1.31), and stroke (RR = 1.22, 95%CI
1.15–1.31) compared to the other two groups. Cancer (overall) relative risk showed little difference across the Health-conscious, Omnivore, and Sweet-tooth groups with RR of 0.98 (95%CI 0.96–1.01), 1.00 (95%CI 0.98–1.03), and 1.01
(95%CI 0.98–1.04), respectively. The Health-conscious group was associated with lower levels of inflammatory
biomarkers (e.g., C-reactive Protein) which are also known to be elevated in those with common metabolic diseases
(e.g., cardiovascular disease). Other markers modulated in the Health-conscious group, ketone bodies, insulin-like
growth factor-binding protein (IGFBP), and Growth Hormone 1 were more abundant, while leptin was less abundant.
Further, the IGFBP pathway, which influences IGF1 activity, may be significantly enhanced by dietary choices.

Background: Cancer onset and progression are driven by genetic and epigenetic alterations leading to oncogene
activation and the silencing of tumor suppressor genes. Among epigenetic mechanisms, DNA methylation
(methDNA) is gaining growing interest in cancer. Promoter hypomethylation is associated with oncogene activation
while intragenic methDNA can be involved in transcriptional elongation, alternative spicing, and the activation
of cryptic start sites. Several genes involved in the modulation of the tumor microenvironment are regulated by
methDNA, including the Solute Carrier Family 22 Member 17 (SLC22A17), which is involved in iron trafficking and
extracellular matrix remodeling cooperating with the Gelatinase-Associated Lipocalin (NGAL) ligand. However, the
exact role of intragenic methDNA in cancer has not been fully investigated. Therefore, the aim of the present study is
to explore the role of methDNA in the regulation of SLC22A17 in cutaneous melanoma (CM), used as a tumor model.
Methods: Correlation and differential analyses between SLC22A17 expression and methDNA were performed using
the data contained in The Cancer Genome Atlas and Gene Expression Omnibus databases. Functional studies on
melanoma cell lines treated with 5-Azacytidine (5-Aza) were conducted to assess the correlation between methDNA
and SLC22A17 expression. A validation study on the diagnostic potential of the in silico-identified SLC22A17 methDNA
hotspot was finally performed by analyzing tissue samples obtained from CM patients and healthy controls.
Results: The computational analyses revealed that SLC22A17 was significantly downregulated in CM, and its
expression was related to promoter hypomethylation and intragenic hypermethylation. Moreover, SLC22A17
overexpression and hypermethylation of two intragenic methDNA hotspots were associated with a better clinical
outcome in CM patients. The correlation between SLC22A17 methDNA and expression was confirmed in 5-Aza-treated
cells. In agreement with in silico analyses, the SLC22A17 promoter methylation hotspot showed higher methDNA
levels in CM samples compared to nevi. In addition, the methDNA levels of this hotspot were positively correlated
with advanced CM

Background: Diabetes mellitus (DM) is a progressive disease that involves multiple organs due to increased blood
glucose, and diabetic retinopathy (DR) is the main complication of DM in the eyes and causes irreversible vision loss.
In the pathogenesis of diabetic vascular disease, oxidative stress caused by hyperglycemia plays an important role
in Müller cell impairment. In recent years, AdipoRon, an adiponectin analog that demonstrated important physiological functions in obesity, diabetes, inflammation, and cardiovascular diseases, demonstrated cellular protection
from apoptosis and reduced inflammatory damage through a receptor-dependent mechanism. Here, we investigated
how AdipoRon reduced oxidative stress and apoptosis in Müller glia in a high glucose environment.
Results: By binding to adiponectin receptor 1 on Müller glia, AdipoRon activated 5ʹ adenosine monophosphate-activated protein kinase (AMPK)/acetyl-CoA carboxylase phosphorylation downstream, thereby alleviating oxidative
stress and eventual apoptosis of cells and tissues. Transcriptome sequencing revealed that AdipoRon promoted
the synthesis and expression of early growth response factor 4 (EGR4) and inhibited the cellular protective effects
of AdipoRon in a high-glucose environment by reducing the expression of EGR4. This indicated that AdipoRon played
a protective role through the EGR4 and classical AMPK pathways.
Conclusions: This provides a new target for the early treatment of DR

Background: Tandem C2 domains, nuclear (TC2N) is a C2 domain‑containing protein that belongs to the carboxyl-terminal type (C‑type) tandem C2 protein family, and acts as an oncogenic driver in several cancers. Previously, we
preliminarily reported that TC2N mediates the PI3K‑Akt signaling pathway to inhibit tumor growth of breast cancer
(BC) cells. Beyond that, its precise biological functions and detailed molecular mechanisms in BC development
and progression are not fully understood.
Methods: Tumor tissues of 212 BC patients were subjected to tissue microarray and further assessed the associations of TC2N expression with pathological parameters and FASN expression. The protein levels of TC2N and FASN
in cell lines and tumor specimens were monitored by qRT‑PCR, WB, immunofluorescence and immunohistochemistry.
In vitro cell assays, in vivo nude mice model was used to assess the effect of TC2N ectopic expression on tumor metastasis and stemness of breast cancer cells. The downstream signaling pathway or target molecule of TC2N was mined
using a combination of transcriptomics, proteomics and lipidomics, and the underlying mechanism was explored
by WB and co‑IP assays.
Results: Here, we found that the expression of TC2N remarkedly silenced in metastatic and poorly differentiated
tumors. Function‑wide, TC2N strongly inhibits tumor metastasis and stem‑like properties of BC via inhibition of fatty
acid synthesis. Mechanism‑wise, TC2N blocks neddylated PTEN‑mediated FASN stabilization by a dual mechanism.
The C2B domain is crucial for nuclear localization of TC2N, further consolidating the TRIM21‑mediated ubiquitylation
and degradation of FASN by competing with neddylated PTEN for binding to FASN in nucleus. On the other hand,
cytoplasmic TC2N interacts with import proteins, thereby restraining nuclear import of PTEN to decrease neddylated
PTEN level.
Conclusions: Altogether, we demonstrate a previously unidentified role and mechanism of TC2N in regulation of lipid
metabolism and PTEN neddylation, providing a potential therapeutic target for anti‑cancer.

NAD(P)H Quinone Dehydrogenase 1 (NQO1) plays a pivotal role in the regulation of neuronal function and synaptic
plasticity, cellular adaptation to oxidative stress, neuroinflammatory and degenerative processes, and tumorigenesis
in the central nervous system (CNS). Impairment of the NQO1 activity in the CNS can result in abnormal neurotransmitter release and clearance, increased oxidative stress, and aggravated cellular injury/death. Furthermore, it can
cause disturbances in neural circuit function and synaptic neurotransmission. The abnormalities of NQO1 enzyme
activity have been linked to the pathophysiological mechanisms of multiple neurological disorders, including Parkinson’s disease, Alzheimer’s disease, epilepsy, multiple sclerosis, cerebrovascular disease, traumatic brain injury,
and brain malignancy. NQO1 contributes to various dimensions of tumorigenesis and treatment response in various
brain tumors. The precise mechanisms through which abnormalities in NQO1 function contribute to these neurological disorders continue to be a subject of ongoing research. Building upon the existing knowledge, the present study
reviews current investigations describing the role of NQO1 dysregulations in various neurological disorders. This study
emphasizes the potential of NQO1 as a biomarker in diagnostic and prognostic approaches, as well as its suitability
as a target for drug development strategies in neurological disorders.
