NAD+ Precursors Restore Mitophagy and Reverse Aging Markers: Preclinical Findings

SynopsisSelective removal of damaged mitochondria (mitophagy) is crucial for cell health. Human cells show active basal mitophagy, mediated by the PINK1/Parkin pathway and p62 as a receptor. Mitoph...

Nicotinamide Riboside Prevents Muscle Fatigue in Pigs: Preclinical Findings

SynopsisThis study tested how different doses of nicotinamide riboside (NR) affect muscle fatigue in pigs. One hundred barrows were fed diets with 0, 15, 30, or 45 mg NR per kg of body weight, or g...

Nicotinamide Riboside Helps Improve Symptoms in Lupus: Preclinical Findings

SynopsisThe protein PPP2R2A helps regulate the immune system, and in lupus-prone mice, T cells lacking this protein caused less autoimmunity and kidney damage. Without PPP2R2A, T cells produced mor...

Nicotinamide Riboside Protects Mitochondria in Aging Kidneys: Preclinical Findings

SynopsisAs kidneys age, their cells, especially in the distal tubules, undergo changes in mitochondrial structure and function, but little is known about how aging or anti-aging interventions affec...

Effects of Nicotinamide Riboside on Mitochondrial Health and Dopamine in Parkinson's Disease: Preclinical Findings

SynopsisParkinson's disease (PD) involves mitochondrial dysfunction, reduced proteasome activity, and dopamine depletion. NR activated mitochondrial function in C. elegans, rescuing α-synuclein-rel...

Nicotinamide Riboside Preserves Retinal Cells and Mitochondrial Function in Glucocorticoid-Induced Glaucomae: Preclinical Findings

SynopsisGlucocorticoid-induced glaucoma (GIG) is a common side effect of steroid use that can cause blindness by damaging the eye's trabecular meshwork (TM), raising eye pressure, and killing retin...

Targeting Autophagy-NAD Pathway Protects Cells in Niemann-Pick Type C1 Disease: Preclinical Findings

SynopsisImpaired autophagy, which leads to the buildup of misfolded proteins and damaged organelles, has been linked to many human diseases. Loss of autophagy in metabolically active cells can caus...
