IHC of FOXA1 on an FFPE Breast Carcinoma Tissue
| Intended Use | For In Vitro Diagnostic Use | |||||||||||||||||||||||||||||||||||
| Summary and Explanation | 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. FOXA1 is a downstream target of GATA3 in the mammary gland. FOXA1 in breast cancer is highly correlated with ERα+, GATA3+, and PR+ protein expression as well as endocrine signaling. FOXA1 absence in ERα+ cancer might identify ERa cancers that are resistant to endocrine therapy. In ERα− breast cancer, FOXA1 is highly correlated with improved disease free survival and GATA3. Expression in ERα− cancers may identify a subset of tumors that is responsive to other endocrine therapies such as androgen receptor antagonist treatment. | |||||||||||||||||||||||||||||||||||
