UNLABELLED With no approved pharmacological treatment, nonalcoholic fatty liver disease (NAFLD) is now the most common cause of chronic liver disease in Western countries and its worldwide prevalence continues to increase along with the growing obesity epidemic. Here, we show that a high-fat high-sucrose (HFHS) diet, eliciting chronic hepatosteatosis(More)
Neuromuscular diseases are often caused by inherited mutations that lead to progressive skeletal muscle weakness and degeneration. In diverse populations of normal healthy mice, we observed correlations between the abundance of mRNA transcripts related to mitochondrial biogenesis, the dystrophin-sarcoglycan complex, and nicotinamide adenine dinucleotide(More)
Adult stem cells (SCs) are essential for tissue maintenance and regeneration yet are susceptible to senescence during aging. We demonstrate the importance of the amount of the oxidized form of cellular nicotinamide adenine dinucleotide (NAD(+)) and its effect on mitochondrial activity as a pivotal switch to modulate muscle SC (MuSC) senescence. Treatment(More)
BACKGROUND & AIMS To date, no pharmacological therapy has been approved for non-alcoholic fatty liver disease (NAFLD). The aim of the present study was to evaluate the therapeutic potential of poly ADP-ribose polymerase (PARP) inhibitors in mouse models of NAFLD. METHODS As poly ADP-ribosylation (PARylation) of proteins by PARPs consumes nicotinamide(More)
BACKGROUND & AIMS Mitochondrial dysfunction, oxidative stress, inflammation, and metabolic reprograming are crucial contributors of hepatic injury and subsequent development of liver fibrosis. Poly(ADP-ribose) polymerases (PARP) and their interplay with sirtuins have an important role in the regulation of intermediary metabolism, however, if PARP inhibition(More)
