Forkhead transcription factor (FOXA1) is a pioneering factor in the development of some organs and certain cancers. It opens tight chromatin by interacting with nucleosomal core histones. FOXA1 can bind to cis-acting elements and recruit other transcription factors to induce transcription. FOXA1 is involved in embryonic development, establishment of tissue-specific gene expression and regulation of gene expression in differentiated tissues, and participates in the development of a variety of endoderm-derived organ systems, such as liver, pancreas, lung and prostate. FOXA1 is related to many diseases and plays a role in hormone-dependent diseases such as breast cancer and prostate cancer.
