A recent study has found that the overexpression of telomerase reverse transcriptase (TERT), which is a subunit of telomerase, an enzyme essential for telomere maintenance, leads to lifespan extension in mice without significant side effects [1]. Protecting DNA Telomere shortening is a well-known hallmark of aging. Telomeres are protective DNA sequences at the ends of...

Researchers have found that kinesin family member 9 (KIF9), a protein that diminishes with aging, is instrumental in allowing cells to consume harmful proteins and fights Alzheimer's in a mouse model. Consuming amyloids before they become a problem What is Autophagy?Autophagy, derived from ancient Greek, means "eating of self". Autophagy is the way cells break...

A new paper published in Nature Aging suggests that somatic mutations cause significant remodeling of the epigenetic landscape. The findings might be relevant to future anti-aging interventions [1]. The genome and the epigenome Genomic instability and epigenetic alterations are two of the hallmarks of aging [2]. The former occurs in somatic cells due to replication...

How long can people live? This is not just a foundational question in science. The answer has important public policy implications and is of interest to us all. Recent scientific evidence has revealed the answer, so what’s next in humanity’s never-ending battle against disease and the persistent ravages of aging? Larger increases in lifespan not...

Researchers publishing in Physical Review X have discovered compounds that can double the efficiency of the sirtuin SIRT3 in processing NAD+. Looking for a new way to boost enzymes The researchers begin their paper by noting that most drugs administered to people are geared towards inhibition of particular enzymes in order to treat a disease....

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...
