Biologists find a way to boost intestinal stem cell populations

Cells that line the intestinal tract are replaced every few days, a high rate of turnover that relies on a healthy population of intestinal stem cells. MIT and University of Tokyo biologists have now found that aging takes ...

Does dietary restriction protect against age-related leaky gut?

Flies eating a Spartan diet are protected from leaky gut and the systemic inflammation associated with it as they age. Conversely, flies on a rich Atkins-like diet are more prone to developing intestinal permeability, a condition ...

How does dietary restriction extend lifespan in flies?

Lifespan in flies is extended by limiting the activity of a group of proteins called GATA transcription factors (TFs), giving clues to how a moderate reduction in food intake protects against multiple ageing-related diseases, ...

Manipulating mitochondrial networks could promote healthy aging

Manipulating mitochondrial networks inside cells—either by dietary restriction or by genetic manipulation that mimics it—may increase lifespan and promote health, according to new research from Harvard T.H. Chan School ...

Caloric restriction for anti-aging

(Medical Xpress)—The idea that reducing the amount of food you eat can slow metabolism and extend lifespan has been around for a while. Only recently has it become more mainstream. On sites like the popular Fight Aging ...
