PCYT2-regulated lipid biosynthesis is critical to muscle health and ageing

摘要

Human mutations in PCYT2 result in severe pathology with failure to thrive and progressive degenerative disease. Cikes et al. demonstrate that loss of PCYT2-synthesized phosphatidylethanolamines in muscle impairs sarcolemmal lipid bilayer stability and mitochondrial homeostasis, leading to muscle degeneration and premature ageing in mice.
