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 IGF2BP2, with the silencing of IGF2BP2 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 IGF2BP2 expression through targeting miR-7-5p.
