ProteomicsNicotinamide riboside supplementation confers modest effects on skeletal muscle metabolism without mitochondrial and acetyl-proteome remodelingNicotinamide riboside supplementation confers modest effects on skeletal muscle metabolism without mitochondrial and acetyl-proteome remodeling
Nicotinamide riboside supplements (NRS) have been touted as a nutraceutical that promotes cardiometabolic and musculoskeletal health by enhancing nicotinamide adenine dinucleotide (NAD+) biosynthesis, mitochondrial function and/or the activities of NAD-dependent sirtuin deacetylase enzymes. This inv...

ProteomicsDisruption of acetyl-lysine turnover in muscle mitochondria promotes insulin resistance and redox stress without overt respiratory dysfunction
A double knockout (DKO) mouse model harboring muscle-specific deficits in acetyl CoA buffering by carnitine acetyltransferase (CrAT), and lysine deacetylation by SIRT3, resulted in additive hyperacetylation of the mitochondrial proteome, which was augmented exponentially by chronic high fat feeding....

ProteomicsPyruvate-supported flux through medium chain ketothiolase promotes mitochondrial lipid tolerance in cardiac and skeletal muscles
Even-chain acylcarnitine (AC) metabolites, most of which are generated as byproducts of incomplete fatty acid oxidation (FAO), are viewed as biomarkers of mitochondrial lipid stress attributable to one or more metabolic bottlenecks in the beta-oxidation pathway. The origins and functional implicatio...

ProteomicsKetone flux through BDH1 supports metabolic remodeling of skeletal and cardiac muscles in response to intermittent time-restricted feeding
Time-restricted feeding (TRF) has gained attention as a dietary regimen that promotes metabolic health. This study sought to determine if ketone flux in skeletal and cardiac muscles plays an essential role in conferring the health benefits of an intermittent TRF (iTRF) schedule. Notably, we found th...

ProteomicsDisruption of STIM1-mediated Ca2+ sensing and energy metabolism in adult skeletal muscle compromises exercise tolerance, proteostasis and lean mass
STIM1 is a single-pass transmembrane endoplasmic/sarcoplasmic reticulum (E/SR) protein recognized for its role in store operated Ca2+ entry (SOCE), an ancient and ubiquitous signaling pathway. Whereas STIM1 is indispensable during development, its biological and metabolic functions in mature muscle ...

ProteomicsComprehensive respiratory phenomics across multiple models of mitochondrial protein hyperacylation reveals a paradoxically marginal impact on bioenergetics
Acyl CoA metabolites derived from catabolism of carbon fuels can react with lysine residues of mitochondrial proteins, giving rise to a large family of post-translation modifications (PTMs). Mass spectrometry-based detection of thousands of acyl-PTMs scattered throughout the proteome has established...

ProteomicsMetformin Impairs Intestinal Fructose Metabolism
Objective: To investigate the effects of metformin on intestinal carbohydrate metabolism in vivo. Method: Male mice preconditioned with a high-fat, high-sucrose diet were treated orally with metformin or a control solution for two weeks. Fructose metabolism, glucose production from fructose, and p...
