PPM1D is a potential prognostic biomarker and correlates with immune cell infiltration in hepatocellular carcinoma
Figure 3. Correlation analysis of PPM1D expression and infiltration levels of immune cells in HCC tissues based on the TIMER database. PPM1D expression in HCC tissues positively correlates with tumor purity and infiltration levels of B cells, CD8+ T cells, CD4+ T cells, macrophages, and DCs.
