Hepatocyte nuclear factor 4alpha (HNF4) is a transcription factor involved in liver function. Dysregulation of HNF4 leads to hepatocarcinogenesis. However, the role and mechanism of HNF4 in colorectal cancer is still unknown. Here we demonstrate that HNF4 is upregulated in colorectal cancers. and HNF4 upregulation promotes colorectal tumorigenesis. Notably, expression levels of HNF4 are positively correlated with the Wnt/{beta}-catenin signaling pathway in colorectal cancer patients. Further, we showed that HNF4 is transcriptionally activated by Wnt/{beta}-catenin/TCF3 and is at least partially responsible for the oncognesis activity of the Wnt signaling in colorectal cancer. Our findings indicate that HNF4 is a direct target of that Wnt/{beta}-catenin pathway and could play an important role in colorectal carcinogenesis.
