FOXA1 mutations co-opt nascent transcription factor networks in partnership with androgen receptor to enhance prostate tumorigenicity.

Abstract excerpt

Mutations in the pioneer transcription factor FOXA1 occur in 10%-40% of prostate cancers and broadly alter chromatin accessibility. In a cohort of 874 primary and metastatic tumors, we confirm frequent Wing2 missense mutations and indels, as well as C-terminal truncating frameshifts. To define their functional impact, we performed single-nucleus multiome profiling in mouse prostate organoids expressing...
