Nicotinamide Mononucleotide Supplement Adjusts the Gut Microbiome
In today’s open access paper, the authors report on their investigation of the effects of nicotinamide mononucleotide (NMN) supplementation on the gut microbiome in mice. The gut microbiome changes with age, exhibiting a loss of helpful populations that produce metabolites necessary to health, and the growth in harmful populations that provoke chronic inflammation. Rejuvenating the aged gut microbiome via fecal microbiota transplantation from a...

Sirtuins Remain an Active Area of Research in Aging
Sirtuins are connected to the upregulation of cellular stress response mechanisms triggered by, for example, calorie restriction. Given the failure of past attempts to intervene in aging at the point of sirtuin 1, it may be that the influence of sirtuins on the pace of aging simply isn’t large enough to be useful. That said, work on other sirtuins, such as...

Imflammasome Induced Cellular Senescence
Researchers here show that signaling related to inflammatory regulation within a cell, undertaken in response to stress, can induce cellular senescence. Preventing the onset of the senescent state in response to some forms of stress may be beneficial, and indeed may be a part of the way in which therapies such as low dose mTOR...
