Abstract

Alterations in epigenetic control of gene expression play an important role in many diseases, including gastric cancer. Many studies have identified a large number of upregulated oncogenic miRNAs and downregulated tumour-suppressor miRNAs in this type of cancer. In this review, we provide an overview of the role of miRNAs, pointing to their potential to be useful as diagnostic and/or prognostic biomarkers in gastric cancer. Moreover, we discuss the influence of polymorphisms and epigenetic modifications on miRNA activity.

摘要

基因表达表观遗传调控的改变在包括胃癌在内的许多疾病中起着重要作用。许多研究已经在这类癌症中鉴定出大量上调的致癌miRNA和下调的肿瘤抑制miRNA。在这篇综述中,我们概述了miRNA的作用,指出它们作为胃癌诊断和/或预后生物标志物的潜在用途。此外,我们讨论了多态性和表观遗传修饰对miRNA活性的影响。
