Witryna31 sty 2024 · Nicotinamide adenine dinucleotide (NAD +) and its precursor metabolites are emerging as important regulators of both cell metabolism and cell state. Interestingly, the role of NAD + in human embryonic stem cell (hESC) metabolism and the regulation of pluripotent cell state is unresolved. Witryna2 lip 2024 · NAD + levels decrease during aging in mice, worms, and humans, thereby turning down the activities of sirtuins. Dietary NAD + precursors are effectively taken up by cells, mice, and humans and offset this NAD + decline, leading to health benefits, including a reversal of stem cell aging and an extended lifespan in mice.
