Single gene change increases mouse lifespan by 20 percent

By lowering the expression of a single gene, researchers at the National Institutes of Health have extended the average lifespan of a group of mice by about 20 percent—the equivalent of raising the average human lifespan ...

Key molecular pathways leading to Alzheimer's identified

Key molecular pathways that ultimately lead to late-onset Alzheimer's disease, the most common form of the disorder, have been identified by researchers at Columbia University Medical Center (CUMC). The study, which used ...

Heading for regeneration

The rabbit can't do it, neither can a frog, but zebrafish and axolotls can and flatworms are true masters of the craft: Regeneration. Why some animals can re-grow lost body parts or organs while others cannot remains a big ...

Researcher studies protein's role in aging

With time, the amino acid known as asparagine will eventually degrade. Long considered a type of protein "damage," the phenomenon has come to be accepted as yet another part of aging: our hair turns gray, our joints begin ...

Critical pathway in cell cycle may lead to cancer development

A team of scientists at the Salk Institute for Biological Studies has identified why disruption of a vital pathway in cell cycle control leads to the proliferation of cancer cells. Their findings on telomeres, the stretches ...

Researchers identify potential biomarker for cancer diagnosis

Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments, or whole chromosomes that were not incorporated into daughter cells after cell ...
