Targeting translesion synthesis to facilitate the eradication of ovarian cancer stem cells by platinum-based therapy

Abstract

Understanding the mechanisms by which cancer stem cells (CSCs) survive chemotherapy is essential for the development of new therapies. Recently, we demonstrated that ovarian CSCs survive cisplatin treatment through enhanced expression of DNA polymerase η (Pol η). Identification of micro RNA-93 (miR-93) as the regulator of Pol η provides a novel target to improve the outcome of platinum-based therapy.
