Effect of Hepatic Lipid Overload on Accelerated Hepatocyte Proliferation Promoted by HGF Expression via the SphK1/S1PR2 Pathway in MCD-diet Mouse Partial Hepatectomy.

ABSTRACT: Metabolic dysfunction-associated steatotic liver disease (MASLD) is becoming a major health problem worldwide. Liver regeneration is crucial for restoring liver function, and is regulated by extraordinary complex process, involving numerous factors under both physiologic and pathologic conditions. Sphingosine-1-phosphate (S1P), a bioactive sphingolipid synthesized by sphingosine kinase 1 (SphK1), plays an important role in liver function through S1P receptors (S1PRs)-expressing cells. In this study, we investigated the effect of lipid overload on hepatocyte proliferation in a mouse hepatic steatosis model induced by feeding a methionine- and choline-deficient (MCD) diet. After 50% partial hepatectomy (PHx), liver tissues were sampled at various timepoints and then analyzed by immunohistoch
