The mitochondrial membrane lipid cardiolipin directly governs fiber‑type adaptations in aging skeletal muscle via the estrogen‑related receptor γ, a mechanism described as a hidden molecular switch in recent reports. The discovery clarifies a longstanding paradox in how muscle fibers remodel with age, linking lipid signaling to estrogen‑related pathways.
It is relevant to older adults experiencing sarcopenia and to scientists studying muscle plasticity. The study appears in Nature and is echoed by Science Connected, Yahoo and Medical Xpress, indicating broad scientific interest.
Ongoing work will test whether modulating cardiolipin or estrogen‑related receptor γ can alter muscle performance in the elderly. These findings could inform future therapeutic strategies aimed at preserving muscle function as people age.
