BRCA1 and ovarian cancer: Nearly 20% of cases of high‐grade ovarian serous adenocarcinoma have BRCA germline mutations, of which more than 40% do not have a family history of cancer.6 BRCA1 plays an important role in many life processes, including transcriptional regulation, double‐stranded DNA damage repair, transcription‐coupled DNA repair, cell cycle regulation, gene silencing, and energy metabolism regulation.7 Our previous studies confirmed that BRCA1 is a key factor in the recurrence and drug resistance of ovarian cancer.8 Emerging evidence suggests that the relationship between autophagy and cancers is twofold.
