Long noncoding RNA small nucleolar RNA host gene 1 (lncRNA SNHG1) plays a crucial role in the occurrence and progression of various tumors. This study investigates the function of lncRNA SNHG1 in hepatocellular carcinoma (HCC). We discovered that lncRNA SNHG1 is significantly upregulated in HCC and markedly enhances cell proliferation, migration, and invasion, while simultaneously suppressing apoptosis in HCC cells. Furthermore, lncRNA SNHG1 was found to downregulate miR-7-5p expression. Overexpression of lncRNA SNHG1 counteracted the suppression of HCC cell migration, proliferation, and invasion caused by miR-7-5p mimics, and reversed the miR-7-5p mimics' enhancement of apoptosis in HCC cells. Additionally, miR-7-5p was shown to negatively regulate , with the silencing of diminishing the abilities of HCC cells to proliferate, migrate, and invade, and increasing their propensity for apoptosis. Overexpression of lncRNA SNHG1 negated these effects. Thus, lncRNA SNHG1 fosters HCC progression by upregulating expression through targeting miR-7-5p.
长链非编码RNA小核仁RNA宿主基因1(lncRNA SNHG1)在各种肿瘤的发生和发展中起着关键作用。本研究探讨lncRNA SNHG1在肝细胞癌(HCC)中的功能。我们发现lncRNA SNHG1在HCC中显著上调,并明显增强细胞增殖、迁移和侵袭,同时抑制HCC细胞凋亡。此外,发现lncRNA SNHG1下调miR-7-5p表达。lncRNA SNHG1的过表达抵消了miR-7-5p模拟物对HCC细胞迁移、增殖和侵袭的抑制作用,并逆转了miR-7-5p模拟物对HCC细胞凋亡的增强作用。此外,miR-7-5p被证明具有负调控作用,其沉默会降低HCC细胞的增殖、迁移和侵袭能力,并增加其凋亡倾向。lncRNA SNHG1的过表达消除了这些影响。因此,lncRNA SNHG1通过靶向miR-7-5p上调[此处原文缺失相关基因名称]表达来促进HCC进展。
