Low-Protein, High-Carbohydrate Diet May Be Key to Longevity, Animal Study Shows

Calorie restriction (CR) and low-protein, high-carbohydrate (LPHC) diets improve cardiometabolic health in mice. Wahl et al show that, like healthspan, CR and LPHC diets positively affect hippocampus biology in mice by influencing hippocampus gene expression, nutrient-sensing pathways, dendritic morphology, and cognition.

Model of TH5487-mediated inhibition of proinflammatory gene expression: inflammation, at its onset and throughout its progress, is associated with generation of reactive oxygen species, causing damage to DNA in particular at guanine-rich promoters; OGG1 binding to oxidized guanines at promoter regions facilitates recruitment of downstream transcription factors that drive proinflammatory gene expression, and a cellular inflammatory response; in the presence of TH5487, OGG1 can no longer interact with DNA substrates in promoters, so proinflammatory gene expression is inhibited, and the cellular inflammatory response is prevented.
