Nicotinamide mononucleotide increases muscle insulin sensitivity in prediabetic women

Synthesis of nicotinamide adenine dinucleotide (NAD+) decreases during aging, which is thought to limit the activity of enzymes that require it for their catalytic activity. Studies in animals indicate that replenishment of cellular NAD+ can have beneficial effects on aging and age-related diseases, but the situation in humans is less clear. Yoshino et al. report the effects of supplementation with the NAD+ precursor nicotinamide mononucleotide in overweight or obese postmenopausal women with prediabetes (see the Perspective by Hepler and Bass). The treatment improved insulin sensitivity in muscle, although a change in NAD+ content was not detected. The treatment also increased the expression of platelet-derived growth factor b. The results support potential therapeutic action of NAD+ supplementation in humans, but how various NAD+ precursors are processed in specific tissues remains to be fully explored.

Structure reveals the activation mechanism of the MC4 receptor to initiate satiation signaling

Science for just $15 USD.
Abstract
Obesity is a global epidemic causing morbidity and impaired quality of life. The melanocortin receptor 4 (MC4R) is at the crux of appetite, energy homeostasis, and body-weight control in the central nervous system and is a prime target for anti-obesity drugs. Here, we present the cryo-EM structure of the human MC4R-G
s signaling complex bound to the agonist setmelanotide, a cyclic peptide recently approved for the treatment of obesity. The work reveals the mechanism of MC4R activation, highlighting a molecular switch that initiates satiation signaling. In addition, our findings indicate that Ca
2+ is required for agonist but not antagonist efficacy. These results fill a gap in understanding MC4R activation and could guide the design of future weight management drugs.View Full Text ....
