Based on the UALCAN database, we found that the protein expression level of CFP in the primary tissue of breast cancer, colon cancer, lung adenocarcinoma, ovarian cancer and uterine corpus endometrial carcinoma were lower than in normal tissues, however, we did not obtain a significant difference in clear cell renal cell carcinoma (Figure 2A-F). The gene discussed is CFP; the disease is clear cell renal carcinoma.
