Long non-coding RNA GACAT3 promotes liver cancer progression by regulating the proliferation, apoptosis and migration of tumor cells.

ABSTRACT: Long non-coding RNA gastric cancer associated transcript 3 (GACAT3), is a newly identified non-coding RNA, which has been found to be involved in the tumorigenesis of gastric cancer. However, the biological function of GACAT3 in liver cancer remains unclear. The present study aimed to determine the expression level and function of GACAT3 in liver cancer. The authors cultured liver cancer cells in vitro and GACAT3 was silenced in the cells. Cell proliferation, apoptosis and migration were determined by MTT assay, flow cytometric analysis and transwell assay, respectively. It was demonstrated that GACAT3 was upregulated in liver cancer tissues. The inhibition of GACAT3 decreased the ability of hepatoma cells to proliferate and migrate, and increased apoptosis of the cells. These findings provide the first evidence, to the best of our knowledge, of the exact role of GACAT3 in liver cancer, suggesting GACAT3 as a potential target for liver cancer therapy in the future.

Project description:Long non-coding RNA (lncRNA) ADAM metallopeptidase with thrombospondin type 1 motif 9 antisense RNA 2 (ADAMTS9-AS2) is involved in various types of cancer, such as ovarian cancer, lung cancer and clear cell renal cell carcinoma. However, the roles of ADAMTS9-AS2 in liver cancer are not completely understood. The present study aimed to determine the functional role of ADAMTS9-AS2 in human liver cancer and investigate the potential underlying molecular mechanisms. The expression levels of ADAMTS9-AS2 and ADAMTS9 were determined following ADAMTS9-AS2 overexpression and knockdown. The results indicated that ADAMTS9-AS2 overexpression and knockdown increased and decreased ADAMTS9 mRNA and protein expression levels, respectively, indicating that alterations in ADAMTS9 expression corresponded with ADAMTS9-AS2 expression. Subsequently, the effects of ADAMTS9-AS2 on liver cancer cell proliferation, migration and invasion were analyzed by performing Cell Counting Kit-8, wound healing and Transwell assays, respectively. The results demonstrated that ADAMTS9-AS2 inhibited liver cancer cell proliferation, migration and invasion. Finally, the effect of ADAMTS9 on PI3K/AKT/mTOR signaling pathway-associated proteins [AKT, phosphorylated-AKT, phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit β (PIK3CB), mTOR and phosphorylated-mTOR], several key autophagy-related proteins [light chain 3-I/II (LC3-I/II), beclin 1 (BECN1) and sequestosome 1 (SQSTM1)] and apoptosis-related proteins (Bax and Bcl-2) was detected via western blotting. The results suggested that ADAMTS9-AS2 downregulated the phosphorylation of AKT and mTOR, the protein expression level of PIK3CB, as well as the expression levels of autophagy protein SQSTM1 and antiapoptotic protein Bcl-2. By contrast, ADAMTS9-AS2 upregulated the expression levels of autophagy proteins LC3-II and BECN1, and the proapoptotic protein Bax. Collectively, ADAMTS9-AS2 inhibited liver cancer cell proliferation, migration and invasion via inhibiting the PI3K/AKT/mTOR signaling pathway. The present study provided a novel insight into the role of ADAMTS9-AS2 in liver cancer.
