Adult stem cell changes underlie rare genetic disease associated with accelerated aging
Adult stem cells may provide an explanation for the cause of a Hutchinson-Gilford Progeria Syndrome (HGPS), a rare disease that causes premature aging in children, according to researchers at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).

Researchers have found that the anti-malarial drug quinine can block a cell's ability to take up the essential amino acid tryptophan, a discovery that may explain many of the adverse side-effects associated with quinine. Once confirmed, these findings would suggest that dietary tryptophan suppleme...Recruitment of reproductive features into other cell types may underlie extended lifespan in animals
In the sense that organisms existing today are connected through a chain of life through their parents, grandparents and other ancestors almost a billion years back to the first animals of the pre-Cambrian era, an animal's reproductive cells can be considered to be immortal. These germline cells...Mayo Clinic: Brain disorder suggests common mechanism may underlie many neurodegenerative diseases

Despite the popular notion that antioxidants, such as vitamins C and E, offer health-promoting benefits by protecting against damaging free radicals, a new study in the August 10 issue of the journal Cell reveals that, in fact, balance is the key. The researchers show in mice that an overload of n...'Guardian of the genome' protein found to underlie skin tanning
A protein known as the "master watchman of the genome" for its ability to guard against cancer-causing DNA damage has been found to provide an entirely different level of cancer protection: By prompting the skin to tan in response to ultraviolet light from the sun, it deters the development of mela...Different strategies underlie the ecology of microbial invasions
