Beyond cell lines, we obtained the IHC slice images of HTRA1, RBBP7, NFE2L2, SCAF11, ABL1, PAK2, and CPTP in colorectal cancer, breast cancer, prostate cancer, lung cancer, and Non-Hodgkin’s Lymphoma from The Human Protein Atlas (HPA) database to assess the expression of these genes in human tumor tissues, although the IHC image of ADORA3 was not available. The gene discussed is PAK2; the disease is lung carcinoma.
