Scientists have alleviated symptoms of the rare premature aging disease ataxia-telangiectasia using NAD+ supplementation in a mouse model [1]. This success deepens our understanding of the role NAD+ plays in aging. The ubiquitous facilitator The coenzyme nicotinamide adenine dinucleotide (NAD+) is one of the foundations of life as we know it, and it may have...

In a cell culture study, researchers have discovered that forcing cancer cells to differentiate into somatic cells can cause them to stop proliferating. Cancer, stem cells, and proliferation The danger of cancer is from its proliferation: its uncontrolled division within the body. This proliferation is explained by the mutated cells exhibiting stem-like properties; in other...

Suppose there was a country ruled by an evil dictator. Further, suppose the entire world was plagued by a terrible disease affecting 100% of the population. The disease isn’t infectious, but it is congenital. It progresses extremely slowly over the course of several decades, but it eventually ends up severely impairing one’s quality of life,...

What is NMN? NMN is short for nicotinamide mononucleotide, a naturally occurring molecule present in all species. On the molecular level, it is a ribonucleotide, a basic structural unit of nucleic acid RNA. In form it consists of a nicotinamide group, a ribose and a phosphate group. It is a precursor molecule of the essential...

A team of researchers led by Dr. Maria Blasco of the Spanish National Cancer Research Center has shown that shorter telomeres make mice more susceptible to kidney fibrosis [1]. The new study not only clearly demonstrates this link but also provides mouse models which can be used to study – and perhaps eventually address –...

A new study in Aging Cell has shown extracellular vesicles from stem cells to extend healthspan and reduce cellular senescence in vitro and in mice. Stem cell exhaustion is a well-studied hallmark of aging that occurs in multiple model organisms and multiple tissue types in humans. This has led to the hypothesis that bolstering these...
