Abstract
Hepatocellular carcinoma HCC is a lethal liver malignancy worldwide In this study we reported that protein phosphatase magnesiumdependent 1δ PPM1D was highly expressed in the majority of HCC cases approximately 59 and significantly associated with high serum αfetoprotein AFP level P = 0044 Kaplan Meier and Cox regression data indicated that PPM1D overexpression was an independent predictor of HCCspecific overall survival HR 2799 95 CI 1346–5818 P = 0006 Overexpressing PPM1D promoted cell viability and invasion whereas RNA interferencemediated knockdown of PPM1D inhibited proliferation invasion and migration of cultured HCC cells In addition PPM1D suppression by small interfering RNA decreased the tumorigenicity of HCC cells in vivo Overall results suggest that PPM1D is a potential prognostic marker and therapeutic target for HCC
