Calorie Restriction tagged posts

Cutting calories significantly may not be an easy task for most, but it’s tied to a host of health benefits ranging from longer lifespan to a much lower chance of developing cancer, heart disease, diabetes and neurodegenerative conditions such as Alzheimer’s.

A new study from teams led by Scripps Research Professors Bruno Conti, PhD, and Gary Siuzdak, PhD, illuminates the critical role that body temperature plays in realizing these diet-induced health benefits. Through their findings, the scientists pave the way toward creating a medicinal compound that imitates the valuable effects of reduced body temperature.

The research appears in Science Signaling.

β-Hydroxybutyrate Prevents Vascular Senescence through hnRNP A1-Mediated Upregulation of Oct4

A molecule produced during fasting or calorie restriction has anti-aging effects on the vascular system, which could reduce the occurrence and severity of human diseases related to blood vessels, such as cardiovascular disease, according to a study led by Georgia State University.

“As people become older, they are more susceptible to disease, like cancer, cardiovascular disease and Alzheimer’s disease,” said Dr. Ming-Hui Zou, senior author of the study, director of the Center for Molecular and Translational Medicine at Georgia State and a Georgia Research Alliance Eminent Scholar in Molecular Medicine. “Age is the most important so-called risk factor for human disease...

Highlights •SIRT1-ΔE2 is a tissue-restricted splice variant of SIRT1 •SIRT1-FL/SIRT1-ΔE2 are indistinguishable vis-à-vis intrinsic catalytic activities •The conserved exon 2 (E2) domain may act to tether substrates •E2 encodes molecular specificity of interactions and functions

Two alternate forms of SIRT1 leads to the discovery of how molecular specificity is encoded. While the search for elixir of life has captivated human imagination for millennia, researchers around the world have put in efforts to extend healthy lifespan and reduce the burden of morbid diseases in an increasingly aging population...
