Next, we evaluated the protein levels of TRAF1-TRAF7 in different human cancer cell lines, including the human ovarian cancer cell SK-OV-3, human melanoma cell MeWo, human malignant glioblastoma cell U251, human prostate cancer cell 22RV1, and human breast cancer cell BT549. The gene discussed is TRAF1; the disease is Familial prostate cancer.
