In the multiple regression analysis leptin, sObR, FLpI, waist-to-hip ratio, HbA1c, lipids, and HOMA-IR correlated independently with HS (P < 0.0001 for all).
Melatonin reverses leptin methylation and expression and decreases inflammation and chronic liver steatosis not via apoptosis or histone deacetylation (HDAC).
Circulating WISP-1/CCN4 positively correlated with body mass index, body fat percentage, leptin and triglyceride levels, hip circumference and fatty liver index.
Our results suggest that mSJH exerts an anti-hepatic steatosis effect via activation of leptin and associated signaling cascades related to lipid metabolism.
We investigated the liver effect of leptin independently of insulin sensitization and appetite suppression using hepatocyte-specific Pten-deficient (AlbCrePtenff) mouse, a model of severe fatty liver with insulin hypersensitivity.
These changes were also accompanied by altered serum levels of leptin, adiponectin, and insulin, as well as by prevention of steatosis (fatty liver) in ActRIIB-mFc-treated ORX mice.
Adoptive transfer of iNKT cells into obese mice or in vivo activation of iNKT cells via their lipid ligand, alpha-galactocylceramide, decreased body fat, triglyceride levels, leptin, and fatty liver and improved insulin sensitivity through anti-inflammatory cytokine production by adipose-derived iNKT cells.
Here we show that high intake of salt activates the aldose reductase-fructokinase pathway in the liver and hypothalamus, leading to endogenous fructose production with the development of leptin resistance and hyperphagia that cause obesity, insulin resistance, and fatty liver.
Both liver tissue and blood samples were processed to evaluate steatosis and NASH changes in histology (Oil Red, Sirius Red and H&E); presence of endothelial damage (CD31, Moesin/p-Moesin, Akt/p-Akt, eNOS/p-eNOS), oxidative stress (iNOS) and fibrosis (αSMA, Col1, PDGF, VEGF) proteins in liver tissue; and inflammatory (IL6, IL10, MCP-1, IL17α, TNFα), liver biochemical function, and hormonal (leptin, ghrelin, visfatin and insulin) alterations in plasma.
In logistic regression analysis, only insulin resistance was associated with portal inflammation), lobular inflammation and steatosis; liver steatosis was related with leptin levels, too.
The probiotic mixture showed promise as a treatment for NAFLD pathogenesis, and may improve HFSD-induced steatosis through its effects on leptin, resistin, inflammatory biomarkers, and hepatic function markers.
In genotype-3 infected patients, SVR was associated only with fibrosis stage and lower homeostasis model assessment insulin resistance at baseline, but not with the degree of steatosis or leptin concentrations.
We demonstrate that brain leptin protects from steatosis by promoting hepatic triglyceride export and decreasing de novo lipogenesis independently of caloric intake.
