BST1 regulates nicotinamide riboside metabolism via its glycohydrolase and base-exchange activities
Nicotinamide riboside (NR) is a NAD + precursor exhibiting beneficial effects against aging. Here the authors demonstrate that orally administered NR increases NAD + levels in a diphasic manner and that bone marrow stromal cell antigen 1 plays a crucial ...

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Objective: A decay in intracellular NAD+ levels is one of the hallmarks of physiological decline in normal tissue functions. Accordingly, dietary supplementation with NAD+ precursors can prevent, alleviate, or even reverse multiple metabolic ...

Nicotinamide riboside alleviates exercise intolerance in ANT1-deficient mice
Objective: Mitochondrial disorders are often characterized by muscle weakness and fatigue. Null mutations in the heart-muscle adenine nucleotide translocator isoform 1 (ANT1) of both humans and mice cause cardiomyopathy and myopathy associated with ...

Abstract Objectives Pediatric acute pancreatitis (AP), Crohn's disease (CD), and irritable bowel syndrome (IBS) are associated with gut dysbiosis, but differences and similarities between conditions are unknown. We hypothesized that gut microbial ecology would differ across these disorders. Methods Stool was collected from 120 subjects (AP [n = 30], CD

ABSTRACT The Nav1.5 channel, a major isoform of voltage‐gated sodium ion channel, is mainly found in ventricular cardiomyocytes, playing a key role in generating essential cardiac action potentials for normal heart rhythms. Mutations in Nav1.5 have been associated with severe heart conditions such as long QT syndrome, Brugada syndrome, cardiac ...

Metabolic remodelling in anthracycline cardiotoxicity: mechanisms and therapeutic insights
Cardiac metabolic remodelling in anthracycline‐induced cardiomyopathy and metabolically oriented cardioprotective strategies. Schematic representation of substrate utilization, mitochondrial bioenergetic function and metabolic flexibility in the healthy heart, in anthracycline‐induced cardiomyopathy and under potential cardioprotective interventions ...

Dietary NA restriction converts the effect of NAMPT inhibition from cytostatic to cytotoxic in SCLC in vivo. ABSTRACT Small‐cell lung cancer (SCLC) is an aggressive malignancy with limited therapeutic options. We previously showed that nicotinic acid riboside (NAR) sustains NAD biosynthesis in vivo and compensates for NAMPT inhibition in SCLC models ...
