B cell lymphoma 6 (BCL6) represses fasting gene expression by opposing peroxisome proliferator-activated receptor alpha (PPARa) activity at enhancers, and its ablation protects against steatosis by enhancing fatty acid catabolism.
A system genetics approach reveals a unique molecular signature of non-alcoholic fatty liver disease in mice and identifies novel genetic factors affecting hepatic steatosis.
Loss of hepatic Cdk1 leads to oxidative stress, increased fatty acids in blood, and hyperinsulinemia, which resulted in insulin resistance and hepatic steatosis, similar as in diabetes.
Glucocorticoid receptor directly regulates the transcriptional activity of peroxisome proliferator-activated alpha (PPARα) before birth in anticipation of the sudden shifts in the postnatal nutrient source and metabolic demands.
Circadian neutrophil infiltration in the liver modulates liver clock-gene expression and daily hepatic metabolism through the secretion of elastase and activation of JNK-FGF21-Bmal1 axis in the hepatocyte.
Long-term increased testosterone improved body composition and bone density, but lowered HDL and raised risks of hypertension, androgenic alopecia, prostate cancer, and spinal stenosis in males.
The hepatic endocannabinoid/CB1R system controls the soluble leptin receptor’s expression and/or subsequent release by Trib3-induced regulation of C/EBP homologous protein levels in hepatocytes to affect leptin signaling in the liver.
