Researchers publishing in Nature Aging have described how mitochondrial stress is a key part of why senolytics are effective. Finding targeted effectiveness What Are Senolytics? Senotherapeutics for Senescent CellsSenolytics work by targeting one of several pro-survival pathways that senescent cells use to evade apoptosis and cling onto life. One of the challenges in dealing with...

Scientists have created “nanoflowers” that nudge donor cells to produce more mitochondria, which can then be transferred to recipient cells to boost their mitochondrial function [1]. Mitochondrial transfer is difficult to improve Energy is required for life, and most energy in our cells is produced by mitochondria. When these organelles start to falter, it's a...

A new report from the Interventions Testing Program adds three new compounds to the list of lifespan-extending compounds confirmed during their experiments: epicatechin, halofuginone, and mitoglitazone [1]. Rigorous testing The National Institute on Aging’s Interventions Testing Program (ITP) is designed to rigorously test potential lifespan-extending compounds with a protocol that ensures reproducibility. In a standard investigation,...

Scientists have discovered a possible mechanism behind age-related inflammation. It involves wrong building blocks being incorporated into mitochondrial DNA during replication and can be countered by adding the correct ones [1]. Too similar to bacteria Mitochondria, the cells’ energy-producing organelles, are considered to have developed from bacteria that once entered an ancient cell and stayed,...

Scientists have found a way to directly stimulate the assembly of Complex I in mitochondria, rescuing memory deficits in mouse models of Alzheimer’s and frontotemporal dementia [1]. Mitochondrial signal transducers Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that harm cells and...

A new study demonstrates that novel gene-editing tools can correct disease-causing mutations in mitochondrial DNA in primary human cells [1]. Smaller editing tools needed Genome-editing tools such as CRISPR were one of the greatest scientific breakthroughs of this century. However, they are only good for editing nuclear DNA. Mitochondria, the energy-producing organelles, have their own...
