LncRNA GAS6 antisense RNA 1 facilitates the tumorigenesis of clear cell renal cell carcinoma by regulating the AMP-activated protein kinase/mTOR signaling pathway.

ABSTRACT: The role of GAS6 antisense RNA 1 (GAS6-AS1) in clear cell renal cell carcinoma (ccRCC) remains unclear. The aim of the present study was to investigate the role and molecular mechanisms of GAS6-AS1 in the progression of ccRCC. GAS6-AS1 was found to be upregulated in ccRCC tissues and cell lines, and patients with high GAS6-AS1 expression levels exhibited a poor prognosis. Small interfering (si)RNA GAS6-AS1 inhibited the activity, colony formation, invasiveness and glycolysis of OSRC-2 and SW839 cells, while GAS6-AS1 overexpression promoted these functions. Moreover, si-GAS6-AS1 increased the phosphorylation level of AMP-activated protein kinase (AMPK) and decreased that of mTOR, as well as decreasing proliferating cell nuclear antigen (PCNA), MMP-2 and hexokinase-2 (HK2) expression, which
