A paper published in Aging explains the relationship of long noncoding RNAs, which change with aging, to age-related macular degeneration (AMD). A disease of deposits and aging This paper begins with a discussion of AMD and its prevalence. AMD is the most common cause of vision loss in people over 70 years old [1]. Its...

In a new paper published in Nature, scientists have found that raising NAD+ levels via supplementation with nicotinamide mononucleotide (NMN) activates SIRT1 to dampen metastasis in mouse TNBC models [1]. A double-edged sword NAD+ is a ubiquitous co-enzyme that facilitates numerous processes in our body, from energy production to DNA repair. Its levels decline with...

Scientists have shown that the NAD+ precursor nicotinamide riboside (NR) alleviates symptoms of leaky gut caused by ethanol consumption in mice by improving mitochondrial function [1]. Nicotinamide Riboside (NR): Benefits and Side EffectsNicotinamide riboside (NR) is a B3 vitamin. Nicotinamide riboside gets converted into nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for life.Read MoreCategory: Supplements...

A recent study published in Molecules has tested multiple thiazole-based derivatives that appear to activate the sirtuin SIRT1 more than resveratrol [1]. Sirtuins Resveratrol, commonly found in grape skins and red wine, generated some of the initial interest in sirtuin activators after initial studies showing many therapeutic benefits, such as cancer prevention [2]. Combined with...

A team of researchers publishing in Cell Death & Disease has found that the age-related decline of mitochondrial calcium uptake family member 3 (MICU3), a regulator of mitochondrial function, is associated with sarcopenia, the aging-associated loss of muscle. Why mitochondria control their calcium uptake The calcium ion, Ca2+, is vital in mitochondrial metabolism and interacts...

A review published in The Malaysian Journal of Medical Sciences has outlined what effects caloric restriction (CR) has on the development and differentiation of stem cells. Stem cells and their exhaustion The reviewers began by discussing stem cell exhaustion, a hallmark of aging and a common concern of aging research that we have covered extensively....
