T-beta-RIII joins the fight against breast cancer

... analysis revealed that the mechanism behind these protective effects of T-beta-RIII was likely to be T-beta-RIII cleavage at the cell membrane, which releases soluble T-beta-RIII that blocks TGF-beta signaling. As low levels of T-beta-RIII were found to be associated with decreased recurrence-free survival of ...

Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

...at allows for the chemical breakdown of the tough, protective casing that houses insects and worms to the severe congestion and polyp formation typical of chronic sinusitis. A team of Hopkins sinus experts has found that the gene for the enzyme, acidic mammalian chitinase (AMCase), is up to 250 times more a...

Intravenous gene therapy protects normal tissue of mice during whole-body radiation

... body. In the study, mice were used to test the protective effects of manganese superoxide dismutase plasmid liposome (MnSOD-PL) gene therapy on the bone marrow during whole-body irradiation. The researchers found that in a control group of mice that received an initial 9 Gy dose of radiation there was 80 pe...

Animals that received transplants essentially regained control of their movement, placebo-treated animals did not recover and those that received neurotrophic factors, ca...

New approach to BSE successful in lab

...the normal variant is PrP-C. PrP-C seems to have a protective effect in diseases like a stroke. Interestingly, mice which cannot produce any PrP-C appear to be completely healthy. This has become the starting point for a new therapeutic approach which for some years now has been current in research circles: can...

Record ozone loss during 2006 over South Pole

...Atmospheric Engineer Claus Zehner said. Ozone is a protective layer found about 25 kilometres above us mostly in the stratospheric stratum of the atmosphere that acts as a sunlight filter shielding life on Earth from harmful ultraviolet rays. Over the last decade the ozone level has lowered by about 0,3% per ye...

Unique gene regulation gives chilly bugs survival advantage at bottom of the world

...a) lose their ability to continually express these protective heat-shock proteins. Instead, like most animals, adult midges produce these proteins only when they are stressed. The discovery currently appears in the online edition of the Proceedings of the National Academy of Sciences. The proteins help defend...

Early-stage immune system control of HIV may depend on inherited factors

It's in your head: The brain's own globin defends you from shock and stroke

...brain's response to oxygen deprivation and plays a protective role against brain damage. Structurally similar to hemoglobin (blood) and myoglobin (skeletal muscle), neuroglobin is found in neurons and is most prevalent in areas of the brain that have adapted to physiological stress, such as stroke. Unlike hemog...
