Figure 9. Analysis of the protein expression of ARGs in subtype-specific prognostic models by HPA. (A–H) The protein expression of PARP1, GAPDH, FOS, TP63, PRKN, CCL2, BAX and EIF4EBP were determined by immunohistochemistry using indicated antibodies in HPA database, the staining strengths were annotated as Not detected, Low, Medium and High. The bar plots indicating the number of samples with different staining strength in HPA database.
