In this study, we sought to elucidate the role of VRK-1 in regulation of adult life span in C. elegans. We found that overexpression of VRK-1::GFP (green fluorescent protein), which was detected in the nuclei of cells in multiple somatic tissues, including the intestine, increased life span. Conversely, genetic inhibition of vrk-1 decreased life span. We further showed that vrk-1 was essential for the increased life span of mitochondrial respiratory mutants. We demonstrated that VRK-1 was responsible for increasing the level of active and phosphorylated form of AMPK, thus promoting longevity. A Fisetin Variant, CMS121, Slows Disease Progress in an Alzheimer's Mouse Model https://www.fightaging.org/archives/2020/08/a-fisetin-variant-cms121-slows-disease-progress-in-an-alzheimers-mouse-model/ The research materials here are of interest because fisetin has been shown to be a senolytic compound in mice, capable of selectively destroying harmful senescent cells. Other senolytics have reversed the progression of Alzheimer's disease pathology in mouse models of the condition. Destroying senescent cells in the brain reduces inflammatory signaling, and chronic inflammation is a significant mechanism in neurodegenerative conditions such as Alzheimer's disease. Whether this compound works well as a senolytic in humans has yet to be established - a clinical trial is underway, so hopefully we'll find out in the next year or two. The researchers here are not inte...
