A recent study investigated the effect of a single treatment of prostaglandin E2 on improving muscle strength and rejuvenating muscle stem cells in mice. The researchers explored the molecular and epigenetic aspects underlying this rejuvenation [1]. Aging muscle stem cells Sarcopenia, a loss of skeletal muscle mass and strength, is an age-related disorder that leads...

In Aging Cell, Dr. Vadim Gladyshev and a team of researchers have described how elamipretide beneficially affects mitochondrial pathways and reverses frailty in mice. A drug on its way to the clinic As a mitochondria-affecting antioxidant peptide, elamipretide has been, and continues to be, the subject of multiple investigations. As far back as 2004, researchers...

The authors of a recent study describe Ginkgolide B, a compound with senotherapeutic potential that improved muscle health, metabolism, frailty, inflammation, and senescence metrics and increased lifespan in female mice [1]. From East Asia to the clinic Ginkgolide B is a compound that can be extracted from Ginkgo biloba, an East Asian tree known as...

In Aging Cell, researchers have described how different combinations of gut bacteria impact muscle strength in mice. Expanding upon a known link The link between gut bacteria and health is well-documented, and multiple biomarkers have confirmed that a healthy gut leads to health elsewhere [1]. This is not just due to inflammation caused by pathogenic...

A recent study linked probiotic-induced gut microbiome and metabolite changes to improved muscle functioning in older sarcopenia patients [1]. Sarcopenia and the gut Sarcopenia is an age-related condition. People with sarcopenia suffer from a reduction in muscle mass, strength, and function, leading to a decreased quality of life and increased morbidity and mortality [2]. The...

In a study published in Aging Cell, researchers have outlined a relationship between mitochondrial fragmentation in skeletal muscle and the loss of strength with age. Broken power plants Why We Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that harm cells...
