Synopsis Glioblastoma multiforme (GBM) is the most aggressive and deadly form of brain cancer, known for its rapid growth and invasion into surrounding tissue. Because GBM cells rewire their metab...

NAD+ Supports Metabolism in Impaired Urea Cycle: Preclinical Findings

SynopsisProblems in the urea cycle and how they relate to obesity and inflammation are not well understood, partly because classical urea cycle defects are severe and dramatic. To study this, resea...

Fluorinated NR Enhances NAD+ Depletion in Glioblastoma Therapy: Preclinical Findings

Synopsis Glioblastoma is one of the most aggressive and treatment-resistant brain cancers, partly because its cells rely heavily on NAD+, a molecule vital for energy production and survival. The d...

Nicotinamide Riboside Supports Brain Health and Reduces Inflammation in Alzheimer’s Disease: Preclinical Findings

SynopsisNicotinamide riboside (NR), a precursor of NAD+, can improve cognitive function and reduce brain inflammation in Alzheimer's disease (AD) mouse models, even without affecting beta-amyloid p...

NAD+ Precursor Supplementation Enhances Metabolic Efficiency and Antibody Production: Preclinical Findings

Synopsis This study explored how NAD+ precursors can enhance productivity in Chinese hamster ovary (CHO) cells, which are widely used to produce therapeutic antibodies. Previous research showed th...

Nicotinamide Riboside Restores NAD+ and Improves Mitochondrial Function in HIV-Nephropathy: Preclinical Findings

Nicotinamide Riboside Protects the Heart from Blood Flow Injury: Preclinical Findings

SynopsisMyocardial ischemia-reperfusion (I/R) injury damages the heart when blood flow returns to previously blocked tissue, causing oxidative stress, inflammation, and cell death. This study teste...

Nicotinamide Riboside Prevents Chemotherapy-Induced Peripheral Neuropathy: Preclinical Findings

Synopsis Paclitaxel (PTX) is a widely used chemotherapy drug for cancers such as breast, lung, and ovarian cancer, but one of its major side effects is chemotherapy-induced peripheral neuropathy (...

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...

NAD+ Metabolism and Heart Failure: Review

SynopsisNAD+, along with its reduced form NADH, is central to energy metabolism and is also the starting point for NADP+ production and a co-substrate for key enzymes that regulate oxidative stress...

NMRK2 Serves as a Diagnostic Biomarker for Renal Cell Carcinoma: Preclinical Findings

Synopsis Xp11.2 translocation renal cell carcinoma (tRCC) is a rare and aggressive form of kidney cancer that currently lacks reliable diagnostic tools and effective treatments. This study identif...

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...
