The molecular mechanisms behind the potential 'anti-aging' effects of exercise remain to be elucidated. Janssens et al. studied the lipidome of different mouse tissues and human skeletal muscle. They identified an evolutionary conserved 'lipid aging' signature, characterized by bis(monoacylglycero)phosphate accumulation, which, at the muscle level, can be attenuated by exercise.
Keywords: lipidomics; older adults; omics; physical activity.
