Additionally, single-cell RNA sequencing data indicated that EMC8 expression is positively associated with dedifferentiation, hypoxia, and stemness properties of HNSCC cells.

LAG-3 is one of the immune checkpoint receptors expressed on exhausted T cells within the tumor microenvironment (TME), thereby contributing to immune suppression. This phenomenon presents one of the main challenges in implementing immunotherapeutic methods in cancer. Targeting LAG-3 employing mAbs is designed to restore T-cell functionality and increase antitumor immunity. Clinical studies involving Relatlimab, Fianlimab, and Ieramilimab in combination with other immune checkpoint inhibitors (ICIs), such as anti-programmed cell death-1 (PD-1) mAbs, have demonstrated promising clinical outcomes in the treatment of melanoma. Notably, these combinations have been associated with improved progression-free survival (PFS) compared to monotherapy. This review discusses the biology of LAG-3, the pharmacological characteristics of Relatlimab, Fianlimab, and Ieramilimab, as well as their potential synergistic effects when combined with other ICIs.

Given the inconsistent and heterogeneous findings across studies, this meta-analysis aims to comprehensively assess the association between vitamin D receptor (VDR) gene polymorphisms and the risk of GICs.</p><p><strong>Methods: </strong>A systematic search was conducted in MEDLINE, Web of Science, Scopus, and Embase to identify relevant studies investigating the association between VDR polymorphisms and GIC risk. After removing duplicates, studies were screened based on predefined inclusion and exclusion criteria. Data analysis was performed using Comprehensive Meta-Analysis software (version 2). Publication bias was evaluated using Egger's test, and study heterogeneity was assessed using the I² statistic. Pooled odds ratios (ORs) and 95 % confidence intervals (CIs) were calculated.</p><p><strong>Results: </strong>A total of 51 studies were included in the meta-analysis. Significant associations were found between gastric cancer and the FokI polymorphism (ff vs. FF: OR = 1.58; FF+Ff vs. ff: OR = 0.52), as well as the TaqI polymorphism (tt vs. TT: OR = 1.70). For colorectal cancer (CRC), the BsmI variant showed consistent associations in the recessive, heterozygous, and allelic models, even after excluding studies not in Hardy-Weinberg equilibrium. No significant associations were observed for Cdx2 or in relation to esophageal cancer. Subgroup and meta-regression analyses revealed age- and region-specific effects.</p><p><strong>Conclusion: </strong>VDR gene polymorphisms, particularly FokI and TaqI, are significantly associated with gastric cancer risk, while BsmI is linked to increased susceptibility to CRC. No associations were observed for esophageal cancer. These results support the potential role of genetic variants in gastrointestinal carcinogenesis and warrant further validation in diverse populations.</p>","PeriodicalId":19916,"journal":{"name":"Pathology, research and practice","volume":"274 ","pages":"156155"},"PeriodicalIF":3.2,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144817331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
