(Submitter supplied) Severe malnutrition in young children is associated with signs of hepatic dysfunction such as steatosis and hypoalbuminemia, but its etiology is unknown. To investigate the underlying mechanisms of hepatic dysfunction we used a rat model of malnutrition by placing weanling rats on a low protein or control diet (5% or 20% of calories from protein, respectively) for four weeks. Low protein diet-fed rats developed hypoalbuminemia and severe hepatic steatosis, consistent with the human phenotype. more...

(Submitter supplied) BACKGROUND: Correlating in vitro mitochondrial data to outcomes in vivo remains a challenge and improving methods to assess mitochondrial function in vivo would both guide safer candidate selection and support the growing number of discovery programmes targeting mitochondria for pharmacological intervention. OBJECTIVES: The aim was to assess the toxicity profile of a compound with complex III electron transport chain inhibitory activity (GSK932121A) in order to identify markers and mechanisms of mitochondrial perturbation in vivo. more...

(Submitter supplied) Human pluriopotent H9 cells were differentiated to hepatocyte-like cells and exposed to a cocktail of lactate, pyruvate and octanoic acid (LPO) for 48 hours. This stimulated development of macrovesicular steatosis, which has previously been reported to impact on mitochondrial metabolism. Under our experimental conditions, we identified rewiring of the TCA cycle linked to macrovesicular steatosis. As key TCA cycle metabolites, alpha-ketoglutarate, succinate and fumarate impact on ten-eleven translocation (TET) enzyme activity, we hypothesised that this rewiring would impact on levels of 5-hydroxymethylcytosine (5hmC) enrichment across the genome. more...

(Submitter supplied) The goal of this study was to determine the changes to cellular transcriptional programs following induction of intracellular lipid accumulation, with the aim of confirming the utility of this model for exploring mechanisms underlying the pathogenesis of NAFLD. Comparisons with other publically available data confirm that the alterations we observe in mRNA expression are similar to those observed in both humans and rodents.
