Parental metabolic syndrome epigenetically reprograms offspring hepatic lipid metabolism in mice

We report that parental metabolic syndrome epigenetically reprograms members of the TGF-β family, including neuronal regeneration–related protein (NREP) and growth differentiation factor 15 (GDF15). NREP and GDF15 modulate the expression of several genes involved in the regulation of hepatic lipid metabolism. In particular, NREP downregulation increases the protein abundance of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) and ATP-citrate lyase (ACLY) in a TGF-β receptor/PI3K/protein kinase B–dependent manner, to regulate hepatic acetyl-CoA and cholesterol synthesis. Reduced hepatic expression of NREP in patients with NAFLD and substantial correlations between low serum NREP levels and the presence of steatosis and nonalcoholic steatohepatitis highlight the clinical translational relevance of our findings in the context of recent preclinical trials implicating ACLY in NAFLD progression.

Non-alcoholic fatty liver disease is the most common cause of liver disease in the United States, and is estimated to affect up to a quarter of adults in the world. It is defined by excess fat accumulating in the liver and usually occurs in people with obesity, high blood sugars (diabetes), abnormal cholesterol or triglyceride levels, or high blood pressure. These disorders often run together and as a group are called metabolic syndrome. The “non-alcoholic” part of “non-alcoholic fatty liver disease” is important to distinguish it from alcohol-related liver disease, which can also cause excess liver...

Authors: Serradilla Martín M, Oliver Guillén JR, Palomares Cano A, Ramia Ángel JM Abstract The term "metabolic syndrome" refers to a group of alterations comprising central obesity reduced high-density lipoprotein cholesterol concentrations, elevated triglyceride concentrations, arterial hypertension, and hyperglycemia. This syndrome has established itself as one of the epidemics of the 21st century. Among its causative agents are insulin resistance, leptin and adiponectin, changes in microbiota, and epigenetics. Its incidence in the European population is estimated to be around 25%. ...

This study aimed to investigate putative risk factors differentially related with NAFLD in obese males and females diagnosed with metabolic syndrome (MetS), stratified using the non-invasive hepatic steatosis index (HSI). METHODS AND RESULTS: a cross-sectional analysis of the PREDIMED Plus study was performed of 278 participants with MetS (141 males and 137 females) of the Navarra-Nutrition node. Subjects were categorized by HSI tertiles and gender. Baseline clinical, biochemical variants and adherence to a Mediterranean diet and physical activity were evaluated. Multivariate analyses showed that females had 4.54 more ...

This study aimed to investigate the effects of a 12-week multicomponent intervention program in markers of metabolic syndrome and NAFLD in Brazilian overweight/obese low-income school-aged children.MethodsThis quasi-experimental study comprised overweight/obese school-aged children, aged 7 –13 years. The participants were assigned to intervention (n = 17) or control group (n = 18). The multicomponent intervention was developed during 12 weeks, consisting of exercise sessions (twice/week; 1 h), nutritional education sessions (once/month), and parental support (twice/week). The fol...
