GSTP1 and Familial prostate cancer: Overexpression of GSTP1 has been found in different types of cancer and may be involved in the development of resistance to chemotherapeutics in cancer cells, such as the resistance of ovarian cancer cells against carboplatin and cisplatin, breast cancer cells and prostate cancer cells against adriamycin, gastric cancer cells against 5-fluorouracil and cisplatin, and neurogliomas against cisplatin and irinotecan [22,217,218].
