Abstract

Epstein-Barr virus (EBV), the first human virus identified with oncogenic properties, encodes a class of microRNAs known as miR-BART (BamHI-A rightward transcript microRNAs). This study investigates the pivotal role of EBV-miR-BART14-3p in the progression of gastric cancer, particularly focusing on its effects on epithelial-mesenchymal transition (EMT), cell proliferation, and migration. EBV-associated gastric cancer (EBVaGC) is distinguished by unique genomic and epigenomic characteristics, with EBV miRNAs significantly influencing tumor biology by regulating gene expression. Our research demonstrates that EBV-miR-BART14-3p facilitates gastric cancer cell migration and invasion by targeting the tumor suppressor gene LACTB, which in turn activates the Phosphoinositide 3-kinase (PI3K)/AKT signaling pathway, a critical driver of EMT. The suppression of LACTB in EBVaGC highlights its crucial role in inhibiting tumor progression. These findings position EBV-miR-BART14-3p as a key player in gastric cancer development and underscore its potential as both a prognostic biomarker and a therapeutic target for EBVaGC.

EBV-miR-BART14-3p靶向LACTB促进胃癌细胞增殖和迁移

爱泼斯坦-巴尔病毒（EBV）是第一个被发现具有致癌特性的人类病毒，它编码一类被称为miR-BART （BamHI-A向右转录microRNAs）的microrna。本研究探讨EBV-miR-BART14-3p在胃癌进展中的关键作用，特别关注其对上皮-间质转化（EMT）、细胞增殖和迁移的影响。EBV相关胃癌（EBVaGC）具有独特的基因组和表观基因组特征，EBV mirna通过调节基因表达显著影响肿瘤生物学。我们的研究表明EBV-miR-BART14-3p通过靶向肿瘤抑制基因LACTB促进胃癌细胞的迁移和侵袭，进而激活PI3K /AKT信号通路，这是EMT的关键驱动因素。EBVaGC中对LACTB的抑制突出了其在抑制肿瘤进展中的关键作用。这些发现表明EBV-miR-BART14-3p在胃癌的发展中起着关键作用，并强调了其作为EBVaGC的预后生物标志物和治疗靶点的潜力。

期刊介绍： Biochemical Genetics welcomes original manuscripts that address and test clear scientific hypotheses, are directed to a broad scientific audience, and clearly contribute to the advancement of the field through the use of sound sampling or experimental design, reliable analytical methodologies and robust statistical analyses. Although studies focusing on particular regions and target organisms are welcome, it is not the journal’s goal to publish essentially descriptive studies that provide results with narrow applicability, or are based on very small samples or pseudoreplication. Rather, Biochemical Genetics welcomes review articles that go beyond summarizing previous publications and create added value through the systematic analysis and critique of the current state of knowledge or by conducting meta-analyses. Methodological articles are also within the scope of Biological Genetics, particularly when new laboratory techniques or computational approaches are fully described and thoroughly compared with the existing benchmark methods. Biochemical Genetics welcomes articles on the following topics: Genomics; Proteomics; Population genetics; Phylogenetics; Metagenomics; Microbial genetics; Genetics and evolution of wild and cultivated plants; Animal genetics and evolution; Human genetics and evolution; Genetic disorders; Genetic markers of diseases; Gene technology and therapy; Experimental and analytical methods; Statistical and computational methods.
