Role of PGC-1α in the Mitochondrial NAD + Pool in Metabolic Diseases.
2021
Mitochondria play vital roles, including ATP generation, regulation of cellular metabolism, and cell survival. Mitochondria contain the majority of cellular nicotinamide adenine dinucleotide (NAD+), which an essential cofactor that regulates metabolic function. A decrease in both mitochondria biogenesis and NAD+ is a characteristic of metabolic diseases, and peroxisome proliferator-activated receptor γ coactivator 1-α (PGC-1α) orchestrates mitochondrial biogenesis and is involved in mitochondrial NAD+ pool. Here we discuss how PGC-1α is involved in the NAD+ synthesis pathway and metabolism, as well as the strategy for increasing the NAD+ pool in the metabolic disease state.
