Enriched environment
Publishing in Aging, researchers have reversed the early aging of prenatally harmed young mice by exposing them to a more enriched environment. Young organisms born old Newborn rodents from sleep-deprived mothers have conditions that are biologically similar to the processes of aging. One rat study found that maternal sleep deprivation causes these animals to be...
Resveratrol foods
According to a review published in Food Science and Human Wellness, resveratrol has a positive impact on mitochondrial dysfunction, one of the hallmarks of aging. A hallmark with downstream consequences Why we Age: Mitochondrial DysfunctionAs they age, the mitochondria in our cells lose their ability to provide cellular energy and release reactive oxygen species that...
Effect of AMD
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...
Triple negative
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...
Intestinal molecules
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...
Improvement
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...
