Cancer&Entry Information

Cancer Name	hepatocellular carcinoma
ICD-0-3	C22.0
Methods	qPCR, Western blot, Luciferase reporter assay
Sample	Human HCC cell lines including HepG2 and Hep3b, HCC and corresponding adjacent normal tissues
Expression Pattern	up-regulated
Function Description	OSER1-AS1 was highly expressed in HCC tissues and the high expression of OSER1-AS1 was closely associated with larger tumor size, advanced tumor stages, lower disease free survival and overall survival of HCC patients. OSER1-AS1 knockdown significantly inhibited the proliferation, invasion and migration of HCC cells, and induced the apoptosis. In addition, the dual luciferase reporter assay directly demonstrated that OSER1-AS1 functioned as a molecular sponge for miR-372-3p to promote Rab23 expression. Moreover, the results of immunohistochemistry and western blot analysis showed that Rab23 was highly expressed in HCC tissues, and the high expression of Rab23 was closely associated with the poor overall survival of HCC patients. Immunofluorescence assay also found the subcellular localization of Rab23 in HCC cells. Rab23 was obviously downregulated in cells that were transfected with miR-372-3p mimics. MiR-372-3p mimics significantly inhibited the proliferation and invasion of HCC cells). Rab23 restoration partially reversed miR-372-3p-induced tumor suppressive effects on HCC cells.
