摘      要：Background:Hepatocellular carcinoma(HCC)is one of the most prevalent human cancers with high *** non-coding RNA heart and neural crest derivatives expressed 2 anti-sense 1(HAND2-AS1)is down-regulated in several cancers including HCC,yet the precise mechanisms how HAND2-AS1 regulates cell survival in HCC remains poorly ***:The expression levels of HAND2-AS1 and miR-300 were measured using quantitative real-time *** protein levels of suppressor of cytokine signaling 5(SOCS5),Bcl-2,Bax and cleaved caspase-3 were determined by Western *** viability and cell proliferation were assessed using cell counting kit-8 and clone formation assay,*** apoptosis was detected using flow *** interactions between HAND2-AS1 and miR-300,miR-300 and SOCS5 were validated using luciferase reporter ***:HAND2-AS1 was down-regulated in HCC tissues and cell lines,and the expression level of HAND2-AS1 was positively correlated to patient ***2-AS1 over-expression reduced viability and proliferation in HCC *** HAND2-AS1 level induced apoptosis in HCC cells,accompanied with increased Bax and cleaved caspase-3 levels and decreased Bcl-2 *** also validated that HAND2-AS1 acted as a sponge of miR-300,and there was a negative correlation between expression levels of HAND2-AS1 and miR-300 in HCC ***,we found that SOCS5 was a downstream target of *** addition,miR-300 mimics abolished HAND2-AS1-mediated inhibition of cell viability and ***-300 mimics also reversed the HAND2-AS1-induced apoptosis in HCC ***:lncRNA HAND2-AS1 inhibits proliferation in HCC through regulating miR-300/SOCS5 axis.
