YAP protein has a direct role of in the repression of hepatocyte differentiation through the transcriptional upregulation of Snail and downregulation of HNF4α. Snail and YAP cooperate in the active repression of epithelial/hepatocyte differentiation through their reciprocal upregulation and the HNF4α downregulation. HNF4α actively and stably represses the mesenchymal program, downregulating both Snail and YAP. The same molecular interplay could be involved in different physiological and pathological cell outcomes
