YTHDC1 Is Essential for Postnatal Liver Development and Homeostasis.

ABSTRACT: Hepatocytes play a crucial role in liver function, with their maturation occurring during postnatal development. However, the molecular mechanisms underlying this maturation are not yet fully understood. In this study, YTHDC1 is identified as a key positive regulator of hepatocyte maturation and an essential factor in maintaining liver homeostasis. YTHDC1 expression increases in the liver after birth, and hepatocyte-specific deletion of Ythdc1 impairs hepatocyte maturation, leading to reduced liver weight, liver injury, inflammation, and fibrosis. These defects contribute to the development of nonalcoholic steatohepatitis and hepatocellular carcinoma in mice. YTHDC1 supports postnatal hepatocyte maturation and liver function by enhancing the expression of key transcription factors, FOXA1 a
