Identify FOXA2-interacting proteins in NEPC cells

Following extensive treatment with androgen receptor (AR) pathway inhibitors, a significant number of metastatic prostate cancer develop treatment resistance, and approximately 20% of these castration-resistant prostate cancers (CRPC) transdifferentiate, at least partially, into neuroendocrine (NE) prostate cancer (NEPC).In human cancer, FOXA2 is highly expressed in most of NEPC and a small portion of CRPC patients, has been suggested as a marker of NEPC and elevated in other NE lineage cancers including SCLC. In addition, preclinical studies demonstrated that Foxa2 is required for NEPC tumor growth and metastasis in TRAMP mouse model and associated with NEPC transformation in Pten, Trp53, and Rb1 triple knockout mouse model. However, whether FOXA2 is an essential driver of NEPC, and the underlying mechanism in shaping epigenetic landscape of NEPC is largely unknown.
