These results suggest that HNF3α expression is negatively associated with survival in patients with breast cancer.[42] In renal tubular epithelial cells, we found that TGF‐β1 can induce an increase in HNF3α expression, and HNF3α mediated the TGF‐β1‐induced pro‐fibrotic response. This evidence concerns the gene FOXA1 and breast cancer.
