Cohesin down-regulation drives hematopoietic stem cell aging

Aging is characterized by increases in inflammation and decreases in stem cell function. The relationship between these processes remains incompletely understood. Researchers of the Leibniz Institute on Aging (FLI) in Jena, Germany, identified a new role of the protein cohesin in mediating inflammatory signaling in hematopoietic stem cells (HSCs). Cohesin is required for gene regulation

Do cancer treatments accelerate brain aging?

Previously on Medical News Today, we covered a study explaining that an experience called chemo brain affects many people undergoing cancer — particularly breast cancer — treatment. Chemo brain occurs during cancer treatment, and it may last for a long time after the treatment is over. People experiencing it report a loss of quality in

Low-protein high-carb diet shows promise for healthy brain aging

Low-protein high-carbohydrate diets may be the key to longevity, and healthy brain ageing in particular, according to a new mice study from the University of Sydney. Published today in Cell Reports, the research from the University’s Charles Perkins Centre shows improvements in overall health and brain health, as well as learning and memory in mice

Healthy aging: Gut bacteria may prevent disease

In the ancient myth of Tithonus, the eponymous protagonist asks the gods to live forever but forgets to demand eternal youth. Although he gained immortality, the diseases of old age eventually defeat Tithonus, and he bitterly regrets his immortality. While achieving longevity is a goal worth pursuing and an ambition that humankind has harbored since

High Blood Pressure Threatens Aging Brain, Study Says

WEDNESDAY, July 11, 2018 — Here’s yet another reason to get your blood pressure under control: High blood pressure later in life may contribute to blood vessel blockages and tangles linked to Alzheimer’s disease, new research suggests. Tracking nearly 1,300 older people until they died, scientists found markedly higher risks of one or more brain

Dietary supplement shows promise for reversing cardiovascular aging

Scientists have long known that restricting calories can fend off physiological signs of aging, with studies in fruit flies, roundworms, rodents and even people showing that chronically slashing intake by about a third can reap myriad health benefits and, in some cases, extend lifespan. From a public health perspective, that advice would be impractical for
