Lycorine, a natural plant-extract, exerts tumor-suppressive effects towards several cancers, yet its role and related mechanisms in EnCa are largely unknown. The present study first investigated whether lycorine exerts antitumor activity against EnCa cells and then explored the underlying mechanisms. Lycorine reduced viability and clonogenic growth, curtailed migration and invasion, and induced apoptosis in HEC-1-B cells in a concentration-dependent manner, while sparing human endometrial epithelial cells at lower concentrations. To probe the mechanism, we integrated network pharmacology and molecular docking, identifying 90 overlapping lycorine–endometrial cancer targets enriched in PI3K-AKT, NF-κB, mTOR, and NOD-like receptor pathways and predicting favorable binding to three hub proteins (MAPK1, PI3KCA, and CHUK). Consistent with these predictions, lycorine lowered MAPK1, PI3KCA, and CHUK protein levels and dampened downstream signaling. Notably, silencing PI3KCA largely blunted lycorine-induced growth inhibition, apoptosis, and motility changes, indicating that repression of PI3KCA is a key mediator of its effects. Collectively, these findings suggest that lycorine restrains the malignant behaviors of EnCa cells by suppressing PI3KCA-centered signaling and provide a rationale for further validation across additional models and for evaluating rational combinations.","PeriodicalId":18734,"journal":{"name":"Molecular Biology","volume":"60 2","pages":"258-268"},"PeriodicalIF":0.0,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147912184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dysregulation of m6A regulators has been increasingly implicated in cancer, yet their cell type–specific roles and therapeutic value in ovarian cancer remain clearly unexplored. We conducted an integrative analysis of single-cell and bulk RNA sequencing datasets from ovarian tumors and matched non-malignant tissues to identify m6A regulators associated with tumor progression. Functional experiments, including gene knockdown, flow cytometry, metabolic assays, and RIP-seq analysis, were performed to evaluate the role of candidate regulators. A small-molecule inhibitor of IGF2BP2 (CWI1-2) was also used to assess therapeutic potential in ovarian cancer cell lines. IGF2BP2 was identified as the most significantly upregulated m6A reader in malignant epithelial cells and was associated with poor patient prognosis. Knockdown of IGF2BP2 impaired cell proliferation, induced cell cycle arrest and apoptosis, and suppressed glycolytic activity. RIP-seq data revealed that IGF2BP2 directly binds transcripts of key oncogenes including CDK4, BCL2L2, and SLC2A1, thereby stabilizing their expression. Pharmacological inhibition of IGF2BP2 recapitulated the effects of genetic silencing, confirming its essential role in sustaining oncogenic programs in ovarian cancer cells. Our findings establish IGF2BP2 as a critical m6A reader that post-transcriptionally regulates gene networks driving proliferation, survival, and metabolic reprogramming in ovarian cancer. Targeting IGF2BP2 may represent a promising therapeutic strategy for m6A-based precision oncology in ovarian cancer.","PeriodicalId":18734,"journal":{"name":"Molecular Biology","volume":"60 2","pages":"234-246"},"PeriodicalIF":0.0,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147883818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies suggest that macrophage polarization plays a pivotal role in bone homeostasis, with potential modulation by N6-methyladenosine (m6A) modifications. However, the exact mechanisms through which m6A-related genes regulate macrophage polarization and contribute to osteoporosis remain poorly understood. This study aims to explore the involvement of m6A-related genes in osteoporosis, focusing particularly on their effects on macrophage polarization and glycolytic metabolism. Gene expression data related to osteoporosis were retrieved from the GEO database (GSE56816), and differential expression analysis was conducted using the limma package in R. Functional enrichment analysis was performed with clusterProfiler and Metascape, while Weighted Gene Co-expression Network Analysis (WGCNA) was utilized to identify gene modules associated with osteoporosis. The overlap between m6A-related genes, differentially expressed genes (DEGs), and WGCNA-derived genes was examined using Venn diagrams. The role of HNRNPA1 was further investigated both in vitro and in vivo through various techniques, including qRT-PCR, Western blotting, immunofluorescence staining, and ELISA. Differential expression analysis identified 284 key genes linked to osteoporosis. WGCNA clustered these genes into six modules, revealing distinct correlation patterns (positive, negative, or no significant correlation) with osteoporosis. Overexpression of HNRNPA1 was found to upregulate pro-inflammatory cytokines (CXCL9, CXCL10) and glycolytic genes (GLUT1, PFKFB3). In vivo, HNRNPA1 knockdown significantly improved bone metabolic markers in an osteoporosis model, alongside a reduction in the M1 macrophage marker iNOS, an increase in the M2 macrophage marker CD206, and a decrease in the glycolytic gene GLUT1 expression. These results highlight the critical role of HNRNPA1 in regulating macrophage polarization via the glycolytic pathway in the context of osteoporosis. Targeting HNRNPA1 may provide new therapeutic approaches for enhancing bone health and alleviating osteoporosis.","PeriodicalId":18734,"journal":{"name":"Molecular Biology","volume":"59 6","pages":"1019-1034"},"PeriodicalIF":0.0,"publicationDate":"2025-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S002689332570044X.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147914738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Luteolin, a naturally occurring flavonoid with potent antioxidant and anti-inflammatory properties, has shown promise as a therapeutic agent for managing such damage. This study explores the protective effects of luteolin on ethanol-induced injury in gastric epithelial cells (GES-1) and investigates the underlying mechanisms, with a focus on the Keap1/Nrf2 signaling pathway. Our findings demonstrate that luteolin significantly enhances cell viability, reduces lactate dehydrogenase (LDH) release, and helps maintain mitochondrial membrane potential (MMP) in ethanol-treated cells. Luteolin also mitigates oxidative stress by increasing the activity of antioxidant enzyme activities (CAT, SOD) and glutathione (GSH) levels and decreasing malondialdehyde (MDA) levels. Additionally, it suppresses inflammation by reducing the expression of pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) and inhibits apoptosis by modulating the expression of Bax, caspase-3, and Bcl-2. Mechanistically, luteolin activates the Keap1/Nrf2 signaling pathway, which restores redox balance and reduces inflammation, highlighting its central role in luteolin’s protective effects. These results provide valuable insights into the therapeutic potential of luteolin in addressing alcohol-related gastric injuries and oxidative stress-driven disorders, offering a mechanistic basis for its application in clinical settings.","PeriodicalId":18734,"journal":{"name":"Molecular Biology","volume":"59 6","pages":"993-1003"},"PeriodicalIF":0.0,"publicationDate":"2025-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147919241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although some natural substances have been shown to increase intracellular Ca2+ concentration and ROS generation by activating TRPM2 channel and potentiate the anticancer effects of doxorubicin (DOX), and chrysin (CHR) has been shown to enhance the anticancer effect of DOX, its anticancer effect through TRPM2-mediated Ca2+ homeostasis and ROS generation in glioblastoma tumour cells (DBTRG) has not been investigated. This work aimed to clarify the molecular processes behind the synergistic chemotherapeutic action of DOX and CHR in DBTRG cells. For this purpose, we investigated the stimulatory role of CHR on DOX-induced cell death via TRPM2 channel activation in DBTRG cells. DOX treatment caused cell cytotoxicity, increased apoptosis (caspase 3 and 9), ROS, lipid peroxidation levels, and decreased cell viability and antioxidant levels. The combination of CHR and DOX made the treatment even more effective. The effects in cells were reduced with treatments with 2APB, a TRPM2 antagonist. In conclusion, the increase in ROS and cell death levels mediated by TRPM2 activation in DOX-induced DBTRG cells was further enhanced by CHR treatment.

To investigate the role of oxidized low-density lipoprotein receptor 1 (OLR1) in T/HS-induced liver injury, male Sprague-Dawley (SD) rats were utilized to establish a resuscitation after hemorrhagic shock (HS/R) model through controlled bloodletting and mean arterial pressure (MAP) monitoring. Immunohistochemical (IHC) staining revealed a significant upregulation of hepatic OLR1 expression following HS/R. Interfering with OLR1 significantly improved coagulation parameters, as evidenced by shortened thrombin time (TT), prothrombin time (PT), and activated partial thromboplastin time (APTT), along with reduced plasma thrombin-antithrombin (TAT) complex levels. Hematoxylin-eosin (HE) staining revealed extensive hepatocellular necrosis following HS/R, which was significantly alleviated by OLR1 knockdown. Biochemical analysis demonstrated reduced serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and pro-inflammatory cytokines (IL-1β and IL-18), highlighting the protective effect of OLR1 inhibition on liver function. Mechanistic studies revealed that OLR1 mediated HS/R-induced liver injury through the activation of the toll-like receptor 4 (TLR4)/myeloid differentiation primary response 88 (MyD88) pathway and NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome-mediated pyroptosis, both of which were suppressed by OLR1 knockdown. These findings were corroborated in vitro using BRL-3A cells. In conclusion, OLR1 mediated HS/R-induced liver injury by regulating the TLR4/MyD88/NF-κB pathway and pyroptosis. Targeting OLR1 could offer a potential therapeutic strategy to mitigate liver damage, correct coagulation abnormalities, and improve outcomes in T/HS.","PeriodicalId":18734,"journal":{"name":"Molecular Biology","volume":"59 5","pages":"772-783"},"PeriodicalIF":0.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147898873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
