Moreover, related studies about lncRNAs and GC demonstrate that multiple lncRNAs, such as HOXA11-AS, LINC00673, and XIST promote the progression of GC via regulation of β-catenin, LSD1, and miR-101 [23, 25, 26]; whereas, linc00261 inhibits its progression via Slug degradation [27], indicating that lncRNAs may act as potential biomarkers and therapeutic targets for GC. Here, SNAI2 is linked to gastric cancer.
