Survival and cell-cycle alterations were performed after drug treatments in isogenic DT40, DLD1, and OVCAR cell lines with BRCA1, BRCA2, or PALB2 deficiencies and in organoids cultured from prostate cancer patient-derived xenografts with BRCA2 loss.
A number of germline mutations in DNA damage repair genes ( BRCA1, BRCA2, CHEK2, ATM and PALB2) and in DNA mismatch repair genes ( MLH1, MSH2, MSH6 and PMS2) can drive the development of prostate cancer.
The purpose of this article is to provide a review of principles of genetic testing in prostate cancer and highlight the significance of clinical genetic testing of BRCA1/2 and other genes (CHEK2, HOXB13, PALB2), including Lynch syndrome genes (MLH1, MSH2, MSH6, and PMS2) in men with metastatic prostate cancer.
