Interestingly, even after 1 week of the dietary challenge, the liver-specific CtBP2-deficient mice exhibited hepatic steatosis (Fig. 5i and Supplementary Fig. 6j) with liver dysfunction as indicated by the elevated serum alanine aminotransferase (ALT) levels (Fig. 5h). Here, CTBP2 is linked to Hepatic steatosis.
