Researchers publishing in Cell Stem Cell have found that the mitochondrial protein OPA1 is an integral, regulatory part of muscle stem cell activation, the process by which muscle stem cells proliferate and become active muscle tissue (myogenesis) [1]. Another piece of the puzzle We have recently reported on the effects of mitochondrial fusion and fission...

Scientists have drastically improved various symptoms of atherosclerosis in mice by precisely targeting mitochondria with a plant-derived antioxidant [1]. Age-related and deadly Atherosclerosis, the accumulation of plaques on arterial walls, is one of the deadliest age-related diseases. Atherosclerotic plaques, which consist mostly of cholesterol and fat, can impede blood flow in the artery or burst,...

Publishing in GeroScience, a team of researchers that included Nir Barzilai and Matt Kaeberlein examined genes that may affect both mitochondria and lifespan [1]. From the mitochondria to the nucleus Over time, evolution has moved mitochondrial DNA from the individual mitochondria to the nucleus, where they are better protected. SENS Research Foundation, in conjunction with...

Scientists have discovered that immature oocytes maintain their youth by shutting down one of the protein complexes that produce energy in mitochondria [1]. Live slow, stay young Every female is endowed with a finite number of oocytes that form before birth, then reside in the ovaries in a dormant state until maturation and release. Oocytes...

A study published in the Journal of the American Medical Association has examined the dosage and safety of a urolithin A supplement [1]. This study also examined urolithin A's effect on muscle endurance and specific health biomarkers. A randomized, controlled clinical trial  This study is a follow-up to prior work done by the Amazentis company,...

Research published in Circulation has shown that mitochondrial, but not nuclear, telomerase reverse transcriptase (TERT) protects against damage caused by heart attacks in a murine model. A non-canonical role While TERT's name comes from its main function, the protection of telomere length in the cellular nucleus, the researchers make it clear that TERT has other...
