Non-alcoholic fatty liver disease (NAFLD) results from increased hepatic lipid accumulation and steatosis, and is closely linked to liver one-carbon (C1) metabolism. We assessed in C57BL6/N mice whether NAFLD induced by a high-fat (HF) diet over 8 weeks can be reversed by additional 4 weeks of a dietary methyl-donor supplementation (MDS). MDS in the obese(More)
Obesity is an underlying risk factor in the development of cardiovascular disease, dyslipidemia and non-alcoholic fatty liver disease (NAFLD). Increased hepatic lipid accumulation is a hallmark in the progression of NAFLD and impairments in liver phosphatidylcholine (PC) metabolism may be central to the pathogenesis. Hepatic PC biosynthesis, which is linked(More)
Cystic fibrosis (CF) is characterised by the absence of CFTR function resulting in a reduced Cl(-) secretion and an increase in Na+ absorption. This Na+ hyperabsorption is mediated by the human amiloride-sensitive epithelial sodium channel (ENaC), but the underlying mechanisms are still unknown. After demonstrating functional differences of the Na+(More)
Small intestine and liver greatly contribute to whole body lipid, cholesterol and phospholipid metabolism but to which extent cholesterol and phospholipid handling in these tissues is affected by high fat Western-style obesogenic diets remains to be determined. We therefore measured cholesterol and phospholipid concentration in intestine and liver and(More)
In humans, plasma amino acid concentrations of branched-chain amino acids (BCAA) and aromatic amino acids (AAA) increase in states of obesity, insulin resistance and diabetes. We here assessed whether these putative biomarkers can also be identified in two different obesity and diabetic mouse models. C57BL/6 mice with diet-induced obesity (DIO) mimic the(More)
SUPPLEMENTAL FIGURES Figure S1: Experimental design of the MDS feeding trial. Open and gray boxes represent feeding of control (C) and high-fat (HF) diet, respectively, and open-lined and gray-lined boxes represent methyl-donor supplemented control (CMS) and methyl-donor supplemented high-fat (HFMS) dietary feeding, respectively. C and HF mice sacrificed(More)
