Hepatic stearoyl-CoA desaturase deficiency ameliorates hyperglycemia through bile acid signaling in an insulin-independent manner

Mugagga Kalyesubula, Daehan Kim, Woo Sung Kim…·James Mukasa Ntambi

This study shows that liver-specific SCD1 deficiency reduces hyperglycemia and hepatic steatosis in T1D through bile acid-FXR-Glut1 signaling, independent of insulin.

Stearoyl-CoA Desaturases regulate stem and progenitor cell metabolism and function in response to nutrient abundance

Kubra B. Akkaya-Colak, Andrea R. Keller, Maria H. Festing…·Maria M. Mihaylova

This study shows that Stearoyl-CoA Desaturases (SCDs) regulate intestinal stem and progenitor cell metabolism and function in response to nutrient abundance, affecting tissue homeostasis and regeneration.
