SCD and metabolic dysfunction-associated steatotic liver disease: In addition to the changes of 11β-HSD1, 5αR1 and 5βR in the liver, we also found that postnatal overfeeding induced a significant increase in DNL by SREBP-1c, ACC, SCD1 and FASN overexpression in the liver from weaning to adulthood, which might be an important mechanism underlying the development and progression of NAFLD in adulthood, that is, overexposure to GC through 11β-HSD1 up-regulation in the liver.
