Common cancer gene sends death order to tiny killer

...er cells, one missing p53 and the other containing healthy p53. They then looked for any of the 500 known human microRNAs that are activated only in cells containing p53. It turned out that the miR-34a gene is turned on by p53, and in fact, experiments demonstrated that p53 binds directly to the genetic m...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...ins of people with Alzheimer’s disease compared to healthy people. It’s recognized as a critical player in bringing about much of the brain damage that follows a stroke and brain injury, so it’s no surprise that its presence in the brains of Alzheimer’s patients would be assumed to be part of the problem. ...

Research team identifies new Alzheimer's gene

... neuroscientific findings, researchers suggest the healthy form of the GAB2 gene may protect brain cells from developing tangles, one of the hallmarks of Alzheimer’s disease. If the findings are confirmed, this discovery could provide a target for future Alzheimer’s therapeutic drugs. “We hope that this s...

Envisat captures first image of Sargassum from space

...etation plays an important role in determining how healthy it is. Accurately monitoring chlorophyll from space, therefore, provides a valuable tool for modelling primary productivity. "The 709 band used by MERIS is not present on other ocean-colour sensors. It was essential to our detecting Sargassum," G...

Study shows big power of small RNAs, not just proteins, in halting cancer

...es by activating an immune response in surrounding healthy cells. Most suspected that proteins would be revealed as key to the power of p53, but this latest research published June 6 by Nature now identifies miRNAs as a critical force behind the anti-proliferation potential of p53. Expression of most ...

Newly discovered antibody may be body's natural defense against Alzheimer's
