LIPID METABOLISM

NAD+ regeneration drives cancer cell proliferation

NAD+ is a key electron acceptor in proliferating cells, needed to increase biomass. Computational and experimental approaches demonstrate that NAD+ regeneration is critical for de novo lipid synthesis when exogenous sources are limited, underlying cancer cell dependence on lipids when mitochondrial respiration is reduced.
