Brief Summary:This study reveals how castration resistant prostate cancers (CRPC) can produce androgens and become resistant to the inhibitor of androgen production abiraterone. The authors uncover dual phosphorylated-SREBF1 as a sensor of androgen deficiency. Its nuclear translocation and deposition of H2A-K130ac epigenetic marks activates a distinct transcription program that includes SREBF1. This will then lead to intratumoral cholesterol and androgen biosynthesis, liberati...
