Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

A reduced form of nicotinamide riboside defines a new path for NAD+ biosynthesis and acts as an orally bioavailable NAD+ precursor

Molecular Metabolism, 2019
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

Molecular Metabolism, 2022
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 ...

Gut microbiome in pediatric acute pancreatitis and Crohn's disease versus irritable bowel syndrome and healthy controls

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
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

Late INa as a Therapeutic Target: New Strategies, Computational Modelling, Drug Development, and Clinical Translation

Medicinal Research Reviews, EarlyView.
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 ...

Nicotinic Acid Restriction Enhances the Therapeutic Benefit of NAMPT Inhibition in Small‐Cell Lung Cancer Models

Cancer Science, EarlyView.
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 ...

Discoveries of Nicotinamide Riboside as a Nutrient and Conserved NRK Genes Establish a Preiss-Handler Independent Route to NAD+ in Fungi and Humans [PDF]

, 2004
NAD+ is essential for life in all organisms, both as a coenzyme for oxidoreductases and as a source of ADPribosyl groups used in various reactions, including those that retard aging in experimental systems. Nicotinic acid and nicotinamide were defined as

Nicotinamide riboside supplementation dysregulates redox and energy metabolism in rats: Implications for exercise performance

, 2018
New Findings: What is the central question of this study? The aim was to investigate the potential metabolic and redox mechanisms that impaired exercise performance after 21 days of supplementation with 300 mg (kg body weight)−1 of nicotinamide riboside ...
