Nicotinamide Riboside and Metformin Restore Mitochondrial Function: Preclinical Findings

SynopsisMitophagy is the process cells use to clear damaged mitochondria, keeping cells healthy. Defects in this process are linked to neurodegenerative diseases. Using stem cell–derived brain cell...

Nicotinamide Riboside Improves Blood Cell Formation in Aging and Ataxia Telangiectasia: Preclinical Findings

SynopsisNAD+ supplements can boost mitochondrial health and DNA repair, which benefits stem cells in aging or disease. This study tested nicotinamide riboside (NR) in mice with reduced blood stem c...

In Ovo Feeding of Commercial Broiler Eggs: Preclinical Findings

SynopsisScientists have focused on improving muscle growth during early development because the number of muscle fibers formed before birth sets future growth potential. In poultry, feeding embryos...

Nicotinamide Riboside Protects Against Cardiac Hypertrophy by Reducing Inflammation and Oxidative Stress: Preclinical Findings

Synopsis Cardiac hypertrophy, a thickening of the heart muscle caused by pressure overload, can lead to heart failure. In mice, nicotinamide riboside (NR), a precursor to NAD+, reduced heart and l...

Nicotinamide Riboside Supplementation Improves Neurological Scores and Markers of Immune Health in Ataxia Telangiectasia: Clinical Findings

Objectives To investigate the effects of NR supplementation in patients with ataxia telangiectasia (AT). Journal Movement Disorders Key Outcomes NR supplementation improved ataxia scores (SARA an...

Nicotinamide Riboside Reduces Brain Inflammation, Protects Muscle Health, and Enhances Weight Loss in Obesity: Preclinical Findings

Synopsis Obesity treatments like calorie restriction (CR) often cause muscle loss and increase brain inflammation, which can interfere with weight control. In this study, obese rats were given CR,...

NAD+ Precursors in Health, Disease, and Aging: Review

SynopsisNAD+ is an essential molecule that helps the body make energy, send signals between cells, keep mitochondria healthy, and decide whether cells survive or die. Research shows that NAD+ level...

Mitophagy Enhancers, Including Nicotinamide Riboside, Are Protective in Alzheimer's Disease: Preclinical Findings

Synopsis This study examines whether mitophagy enhancers can protect brain cells from the harmful effects of mutant APP and amyloid beta (Aβ) in Alzheimer’s disease (AD). Since mitochondrial dysfu...

Nicotinamide Riboside Has Minor Effect on Energy Metabolism in Obesity: Preclinical Findings

SynopsisNR has been shown to reverse obesity-related health issues in mice, but effects may vary by strain. Researchers compared mildly obese C57BL/6N and C57BL/6J mice on high-fat diets, with or w...

Nicotinamide Riboside Reduces Brain Inflammation and Cellular Aging in Alzheimer’s Disease: Preclinical Findings

Synopsis In Alzheimer’s disease, brain cells often show low NAD+ levels, high inflammation, and impaired cellular cleanup of damaged components. In mice with Alzheimer’s-like brain changes, five m...

Nicotinamide Riboside Reduces Heart Damage in Presence of Fentanyl, Midazolam, and Cangrelor: Preclinical Findings

SynopsisWhen blood flow to the heart is blocked and then restored—a process called ischemia-reperfusion injury—cells can be severely damaged. Researchers tested several potential protective compoun...

Disrupted NAD+ Metabolism Leads to Brain Defects in Zika Virus-Linked Microcephaly: Preclinical Findings

Synopsis Zika virus (ZIKV) infection during pregnancy can cause microcephaly, a condition where babies are born with abnormally small brains. In this study, researchers analyzed infected mouse bra...

Unstable NAD+ Metabolism Leads to Impaired Heart Mitochondrial Function: Preclinical Findings

SynopsisPoly(ADP-ribose) polymerase (PARP) enzymes repair DNA but use NAD+ as fuel. Excessive DNA damage in heart cell mitochondria can overactivate PARP, depleting NAD+ and impairing mitochondrial...

Unique Mutations in Mouse Hepatitis Virus Reduce Virus Replication: Preclinical Findings

SynopsisAll coronaviruses contain a small domain called the macrodomain, or Mac1, within the nonstructural protein 3 (nsp3). Mac1 binds to and removes a molecule called mono-ADP-ribose (MAR) that a...
