S-Nitrosylation of NOTCH1 Regulates Mesenchymal Stem Cells Differentiation Into Hepatocyte-Like Cells by Inhibiting Notch Signalling Pathway.

ABSTRACT: The differentiation of mesenchymal stem cells (MSCs) into hepatocyte-like cells (HLCs) is considered one of the most promising strategies for alternative hepatocyte transplantation to treat end-stage liver disease. To advance this method, it is crucial to gain a deeper understanding of the mechanisms governing hepatogenic differentiation. The study demonstrated that suppression of the intracellular domain release of the Notch pathway receptor via the γ-secretase inhibitor N-[(3, 5-difluorophenyl)acetyl]-L-alanyl-2-phenylglycine-1, 1-dimethylethyl ester (DAPT) significantly promotes the expression of hepatocyte-related genes and proteins in HLCs. Increased expression of intracellular inducible NO synthase (iNOS) during differentiation led to elevated endogenous NO production. Biotin switch
