Description
Description
FOXA1 is a member of the forkhead class of DNA-binding proteins. These hepatocyte nuclear factors are transcriptional activators for liver-specific transcripts such as albumin and transthyretin, and they also interact with chromatin as a pioneer factor. Similar family members in mice have roles in the regulation of metabolism and in the differentiation of the pancreas and liver.
FOXA1 in breast cancer is highly correlated with ERalpha+, GATA3+, and PR+ protein expression as well as endocrine signaling. FOXA1 acts as a pioneer factor for ERa in ERalpha+ breast cancer, and its expression might identify ERalpha+ cancers that undergo rapid reprogramming of ERa signaling that is associated with poor outcomes and treatment resistance. Conversely, in ERalpha− breast cancer FOXA1 is highly correlated with low-grade morphology and improved disease free survival. FOXA1 is a downstream target of GATA3 in the mammary gland. Expression in ERalpha− cancers may identify a subset of tumors that is responsive to other endocrine therapies such as androgen receptor antagonist treatment. [Wiki]
