Forkhead box protein A1 (FOXA1), also known as hepatocyte nuclear factor 3-alpha (HNF-3A), is a protein that in humans is encoded by the FOXA1 gene.^[3][4][5]

Function

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.^[3]

Marker in breast cancer

FOXA1 in breast cancer is highly correlated with ERα⁺, GATA3⁺, and PR⁺ protein expression as well as endocrine signaling. FOXA1 acts as a pioneer factor for ERa in ERα⁺ breast cancer, and its expression might identify ERα⁺ cancers that undergo rapid reprogramming of ERa signaling that is associated with poor outcomes and treatment resistance.^[6] Conversely, in ERα⁻ 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.^[7] Expression in ERα⁻ cancers may identify a subset of tumors that is responsive to other endocrine therapies such as androgen receptor antagonist treatment.^[8][9]

Role in prostate cancer

Mutations in this gene have been recurrently seen in instances of prostate cancer.^[10]
