Abstract

LncRNA has been validated to be related to different cancers, whereas its regulation mechanism in hepatocellular carcinoma (HCC) is poorly known. In this study, LOXL1-AS1 was overexpressed in HCC cell lines, and LOXL1-AS1 knockdown repressed cell proliferation and stimulated apoptosis in HCC. Besides, the activating role of LOXL1-AS1 in the AKT pathway was also confirmed. Further, miR-1224-5p was sponged by LOXL1-AS1, and overexpression exerted inhibitory function in HCC. Moreover, ITPRIPL2 as amiR-1224-5ptarget gene. Meanwhile, ITPRIPL2 deficiency suppressed HCC cell proliferation. Finally, miR-1224-5p inhibitor reversed the hindering role of LOXL1-AS1 depletion in HCC cell proliferation and AKT pathway, and this rescuing effect was offset by ITPRIPL2 silencing. In summary, LOXL1-AS1 induced cell proliferation and suppresses cell apoptosis in primary HCCvia activating AKT pathway, sponging miR-1224-5p and upregulating ITPRIPL2, which may provide some fresh thoughts for researches about the molecular regulation mechanism of lncRNA in HCC.
