Cancer&Entry Information

Cancer Name	hepatocellular carcinoma
ICD-0-3	C22.0
Methods	qPCR, Western blot, Luciferase reporter assay, in vitro knockdown, RIP
Sample	HCC cell lines (HepG2, Hep3B, Huh7 and SMMC7721), normal human liver cells (LO2), HCC tissues and adjacent nontumor tissues, HCC tissues and adjacent nontumor tissues
Expression Pattern	up-regulated
Function Description	We found that DSCAM-AS1 was up-regulated in HCC tissues relative to adjacent non-tumor tissues. Serum levels of DSCAM-AS1 were higher in HCC patients than that in healthy controls. Increased DSCAM-AS1 was associated with poor prognosis. Knockdown of DSCAM-AS1 significantly inhibited HCC cell proliferation, migration and invasion. Moreover, miR-338-3p was confirmed as a direct target of DSCAM-AS1 in HCC cells. The miR-338-3p inhibitor could partially reverse the inhibitory effect of DSCAM-AS1 depletion in HCC cells. DSCAM-AS1 positively regulated CyclinD1 and smoothened (SMO) expression (two targets of miR-338-3p) in HCC cells. Moreover, tumor growth was tremendously retarded in nude mice received injection of SMCC-7721 cells transfected with sh-DSCAM-AS1.
