Obese mice slimmed down by allergy meds
6.8.2009 | Articles - biotech and pharmacy
Over-the-counter allergy medications turn obese, diabetic mice into healthy, normal-weight mice, researchers report. The new research focuses on mast cells, immune system players critical to the inflammatory response involved in allergies. The study appears along with three other independent studies in the July 26 online Nature Medicine that...
Protein p53 plays three cancer-fighting roles
3.8.2009 | Articles - biotech and pharmacy
A new study shows this cancer-controlling protein, p53, does not one, not two, but three different jobs, all in one convenient package. Previous studies have demonstrated that p53 stops cancer from developing by sensing stress, such as DNA damage, and turning on genes that keep cells from dividing until the damage is repaired. The protein, which...
Early testing for Alzheimer’s disease
29.7.2009 | Articles - biotech and pharmacy
pinal fluid compounds can predict in many cases whether people with mild cognitive impairments will develop the disease. Elderly people with mild cognitive losses are at a heightened risk of progressing to Alzheimer’s disease if they have a combination of telltale compounds in their spinal fluid, researchers report in the July 22/29 Journal of...
Mice sperm protected by GPX5 protein
28.7.2009 | Articles - biotech and pharmacy
Older mice without GPX5 are more likely to have offspring with developmental defects. The absence of a protein that protects sperm could have disastrous consequences for a male’s mate and his offspring. A new study by researchers in France shows that a protein called glutathione peroxidase 5, or GPX5 stands guard over sperm and helps prevent...
The gene that makes wiener dogs short-legged
24.7.2009 | Articles - biotech and pharmacy
We may never know how the zebra got its stripes, but we know how the wiener dog got its short legs. Height-challenged dog breeds — including dachshunds, corgis and basset hounds — have an extra copy of a normal gene to thank for their diminutive stature, new research shows.
Schizophrenia risk gets more complex
16.7.2009 | Articles - biotech and pharmacy
Three studies find that thousands of genetic variants probably contribute. Large collections of common genetic variants, rather than the harmful actions of just a few key mutations, probably predispose people to schizophrenia, three large genetic studies suggest.
Caloric restriction extends life in monkeys, study finds
13.7.2009 | Articles - biotech and pharmacy
People who believed calorie restriction wouldn’t extend life in primates might now have to declare themselves a monkey’s uncle. A 20-year study found that Rhesus monkeys fed a nutritious, low-calorie diet have fewer age-related diseases than counterparts on a normal diet, researchers report July 10 in Science. Also, MRIs reveal less shrinking...
Czech scientists and EU regulation
13.7.2009 | GMO - NEWS
The regulation of transgenesis - genetic modification – in Europe is twenty years old. Any rules concerning fast developing field are more or less fossil after such period. More that that: the foundation stone – Directives 90/219/EEC and 90/220/EEC were designed and enforced by the policy pressure by Greens and Communists rather by science...
Estrogen may reprogram prostate cancer gene in black men
29.6.2009 | Articles - biotech and pharmacy
A new study shows how chemical tags on DNA may lead to higher rates of prostate cancer in black men. And estrogen may play a role, researchers reported June 12 at a meeting of the Endocrine Society in Washington, D.C. “It may be that estrogen can reprogram the genome,” says study coauthor Wan-yee Tang of the University of Cincinnati in...
Origins of the swine flu virus
22.6.2009 | Articles - biotech and pharmacy
esearchers use evolutionary history to trace the early days of the pandemic. Closely related forms of the H1N1 strain of influenza virus circulated undetected in swine for years, a study published online June 11 in Nature reports. The virus, which has spread to multiple continents, has now been classified by the World Health Organization as a...
