In Aging, researchers have described how they removed visceral fat from older male mice by targeting the metabolic regulatory protein CD47. A key regulator of metabolism Visible fat carried around the body is subcutaneous fat. While this kind of fat is obviously not healthy to have in large amounts, it is not as immediately dangerous...

A recent study investigated the impact of two amino acids, phenylalanine and tyrosine, on lifespan using UK Biobank data. The researchers reported an association between tyrosine and shorter lifespan, with sex-specific differences. The results for phenylalanine were more inconsistent [1]. One by one Model animal research has shown that protein restriction can extend lifespan. However,...

In Aging Cell, researchers have outlined the relationship between Alzheimer's, increased pain sensitivity, and the enzyme LPCAT2. Pain is among the earliest signs The key characteristics of Alzheimer's disease, such as cognitive decline and brain deterioration, are very well-known [1]. However, other symptoms, such as pain sensitivity, may precede these key manifestations, providing an early...

Scientists have demonstrated that even two days on a Western-like high-fat diet reduce hippocampal glucose availability, which activates a subset of inhibitory neurons and causes memory problems in mice [1]. Is it OK to eat junk occasionally? Metabolic disease and obesity are known to harm cognitive function and have been linked to neurodegenerative diseases such...

In Aging Cell, researchers have published their surprising findings that epigenetic clocks are not significantly related to most measurements of metabolic health after weight loss interventions. The utility of clocks What Are Epigenetic ClocksAn epigenetic clock is a biochemical test that uses DNA methylation levels and accumulation of methyl groups on DNA to determine biological...

A recent study reported that long-term nicotine consumption had a positive impact on motor function in male mice. The beneficial effects were mediated by sphingolipid and NAD+ metabolism [1]. Two faces of tobacco smoking Smoking tobacco is widely considered detrimental to health for multiple good reasons, as it has been associated with increased risks of...
