Spinal degeneration
Researchers publishing in Aging have outlined a relationship between disc degeneration, macrophage polarization, inflammation, and sirtuins, demonstrating their effectiveness in a rat model of the disease. A crippling and painful disease Intervertebral disc degeneration (IDD) is a major cause of pain and disability [1], as it leads to the physical deterioration of the shock-absorbing discs...
Enlarged heart
A paper published today in Nature Cardiovascular Research has explained a relationship between dilated cardiac myopathy (DCM), epigenetic dysregulation, NAD+, and the epigenetic regulatory molecule Kdm8. A gradual decline of ability DCM occurs when the left ventricle of the heart becomes enlarged and loses its ability to pump enough blood. The heart muscle gradually thins,...
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...
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...
Diagram of NADH
What is NAD+? Nicotinamide adenine dinucleotide (NAD+) is a key coenzyme found in all living cells. It is a dinucleotide, which means that it consists of two nucleotides joined through their phosphate groups. One nucleotide contains an adenine base, and the other contains nicotinamide. NAD+ is essential for life, one of the most versatile molecules...
Research mouse
A study published in Aging has shown that the sirtuin SIRT6 has positive effects on multiple hallmarks of aging in the hearts of mice. Sirtuins Sirtuins are a family of proteins that have been shown to have significant effects on longevity in multiple model organisms. In a previous study, the sirtuin SIRT2 was shown to...
