Figure S2 from PD-L1 Expression and Immune Escape in Melanoma Resistance to MAPK Inhibitors

Heat map of immunohistochemical (IHC) expression of tumor PD-L1, HLA-A and HLA-DPB1 (top panel) compared to the RNA expression for the HLA genes (bottom panel). A. Comparison of protein and RNA expression of patients' PRE tumors (n=17). B. Comparison of the change (Î") in protein expression from PRE to EDT to the change in RNA expression (n=8). C. Comparison of the change (Î") in protein expression from PRE to PROG to the change in RNA expression (n=13).
