Abstract

The transdifferentiation from adenocarcinoma to neuroendocrine prostate cancer (NEPC) in men confers antiandrogen therapy resistance. Here our analysis combining CRISPR‒Cas9 screening with single-cell RNA sequencing tracking of tumor transition demonstrated that antiandrogen-induced zinc finger MYND-type containing 8 (ZMYND8)-dependent epigenetic programming orchestrates NEPC transdifferentiation. Ablation of Zmynd8 prevents NEPC development, while ZMYND8 upregulation mediated by achaete-scute homolog 1 promotes NEPC differentiation. We show that forkhead box protein M1 (FOXM1) stabilizes ZMYND8 binding to chromatin regions characterized by H3K4me1-H3K14ac modification and FOXM1 targeting. Antiandrogen therapy releases the SWI/SNF chromatin remodeling complex from the androgen receptor, facilitating its interaction with ZMYND8-FOXM1 to upregulate critical neuroendocrine lineage regulators. We develop iZMYND8-34, a small molecule designed to inhibit ZMYND8's histone recognition, which effectively blocks NEPC development. These findings reveal the critical role of ZMYND8-dependent epigenetic programming induced by androgen deprivation therapy in orchestrating lineage fate. Targeting ZMYND8 emerges as a promising strategy for impeding NEPC development.

期刊介绍： Cancer is a devastating disease responsible for millions of deaths worldwide. However, many of these deaths could be prevented with improved prevention and treatment strategies. To achieve this, it is crucial to focus on accurate diagnosis, effective treatment methods, and understanding the socioeconomic factors that influence cancer rates. Nature Cancer aims to serve as a unique platform for sharing the latest advancements in cancer research across various scientific fields, encompassing life sciences, physical sciences, applied sciences, and social sciences. The journal is particularly interested in fundamental research that enhances our understanding of tumor development and progression, as well as research that translates this knowledge into clinical applications through innovative diagnostic and therapeutic approaches. Additionally, Nature Cancer welcomes clinical studies that inform cancer diagnosis, treatment, and prevention, along with contributions exploring the societal impact of cancer on a global scale. In addition to publishing original research, Nature Cancer will feature Comments, Reviews, News & Views, Features, and Correspondence that hold significant value for the diverse field of cancer research.
