Results

Elevated CDCA2 expression in HCC was associated with malignant features and worse prognosis

CDCA2 knockdown and overexpression in HCC cell lines

CDCA2 promoted HCC cell proliferation and migration in vitro

CDCA2 promoted the G1/S transition of HCC cells possibly by the upregulation and activation of CCND1/CDK4/6 and CCNE1/CDK2

CDCA2 played an antiapoptotic role in HCC cells by inactivating the p38 MAPK pathway and activating the JNK/c-Jun pathway

GO analysis of genes correlated with CDCA2 in HCC

CDCA2 expression was regulated by CYPJ
