PPM1D Is a Potential Prognostic Biomarker and Correlates with Immune Cell Infiltration in Hepatocellular Carcinoma

Protein phosphatase magnesium-dependent 1 delta (PPM1D) mRNA expression was significantly higher in several human cancers, including hepatocellular carcinoma (HCC), than in the corresponding normal human tissues. The PPM1D mRNA high expression in HCC was significantly correlated with poor prognosis.
