Abstract


Background: The dysregulation of LncRNAs is related to the malignant progression of many cancers.

Objective: The study aimed to investigate the expression and the biological role of LncSNHG3 in hepatocellular carcinoma (HCC).

Methods: The TCGA data of the LncSNHG3 in HCC were analyzed. The expression in HCC cell lines was detected by qRT-PCR. Proliferation, migration, and invasion of HepG2 and Huh7 were examined by cell counting kit-8, colony formation, transwell assays, and wound healing assays. At the same time, the interactions among LncSNHG3, miR-152-3p, and JAK1 were confirmed by dual-luciferase reporter assay, RNA immunoprecipitation, subcellular distribution. Xenograft tumor-bearing mice models were used to measure the effect of LncSNHG3 on the growth of HCC in vivo. The apoptosis and epithelial mesenchymal transition (EMT)-associated proteins were checked by WB and IHC.

Results: LncSNHG3 was overexpressed in HCC tissues and cell lines. In addition, it is correlated with the tumor stage and survival time of HCC patients. Down-regulated LncSNHG3 could significantly suppress the EMT progression of HCC in vivo and in vitro. LncSNHG3 could promote the JAK1 expression by sponging miR-152-3p.

Conclusions: LncSNHG3 acted as an oncogene and promoted the EMT procession in HCC by binding miR-152-3p and promoting JAK1 expression. Predictably, LncSNHG3 was used as a potential marker and will be used as a novel therapy target for HCC in the future.
