In a new study, researchers have found that lithocholic acid, a metabolite found in the serum of calorically restricted mice, can mimic the effects of caloric restriction [1]. Restricting calories to live longer Caloric restriction without malnutrition improves healthspan and extended lifespan in multiple model organisms and has been found to have health benefits in...

In Aging Cell, researchers have published details on the pathway by which a compound commonly found in ketone bodies ameliorates osteoarthritis in a rat model. Chondrocytes are crucial in arthritis The cartilage holding joints together is built and maintained by chondrocytes, which synthesize such necessary proteins as collagen and aggrecan [1]. Unfortunately, the cellular senescence...

Researchers publishing in Nature Aging have discovered that inhibiting a glucose transporter leads to a decrease in senescent cells. Forcing a reduction in calories Why we Age: Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part; instead, they emit...

In Nature Communications, researchers have published their discovery of a compound found in carrots that promotes mitochondrial health and improves the physical abilities of older mice. Walking down the caloric restriction pathway Although it is difficult to establish in human beings, caloric restriction is one of the most well-known interventions known to be effective across...

Scientists have found that in killifish, old age is associated with a dampened response to fasting and identified the protein that might be responsible. A similar mechanism might exist in humans [1]. Fast less furious Various fasting regimens are thought to confer health and longevity benefits [2], and some potentially geroprotective drugs actually mimic caloric...

Japanese researchers publishing in Aging have described how improving the AMPK metabolic pathway improves outcomes in a rat model of stroke. Targeting metabolism directly This paper begins with a look back at previous research on the focus of this study, 5′-adenosine monophosphate-activated protein kinase (AMPK). This signaling molecule is described here as 'evolutionarily conserved', meaning...
