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. The gene discussed is TGFB1; the disease is breast carcinoma.
