Nrf2 plays a critical role in the metabolic response during and after spaceflight

Akira Uruno et al. report the volume of epidydimal white adipose tissue and plasma glycerophospholipid and sphingolipid levels in mice increase during spaceflight. These metabolic and physiological changes were largely driven by Nrf2 (NF-E2-related factor-2), ultimately providing a mechanistic target for altering lipid metabolism on Earth and the Great Beyond.
