Body fat: Do your genes fit?

...s have shown that individuals who possess a common modification of GNB3known as GNB3 825T may be susceptible to high blood pressure, a typicalcomplication of obesity. To examine whether the 825T variant in fact associateswith obesity, Hegele and colleagues studied 213 Canadian Inuit. For eachsubject, they measu...

Brain compound's anti-aggression effects appear to reverse in monogamous male rodents

...this year , researchers studied the effects of the modification on femalemice. Instead of gaining increased aggressiveness like the males, the femaleslost their aggressive behavior in the one context where it normally showed up,when they were nursing pups and a strange male mouse came around, putting thepups in ...

Key developmental genes identified, linked to rare syndrome

... Research Center (CVRC) confirmed in mice that DNA modification enzymes produced by genes called Dnmt3a and Dnmt3b control the establishment of methylation patterns - a crucial process that controls gene function. They also find that mutations in the human Dnmt3b gene may cause a condition called ICF syndrome. ...

Smells may trigger alcohol craving, and relapse, among alcoholics

...eeking behavior which, when combined with behavior modification and appropriate therapeutic agents, can greatly advance the prevention and treatment of craving and relapse. Weiss elaborated. "Once we understand what neural and molecular mechanisms become activated by exposure to alcohol-related cues, we will hav...

Monsanto's modified soya beans don't agree with the heat

...culiar to glyphosate resistance. "It's not genetic modification per se that's causing the effects," he says. Vencill says that the bacterial enzyme that imparts resistance to glyphosate affects a major metabolic pathway in the plant, and has the side effect of sending lignin production "into overdrive". Gluphos...

Increased production of antibiotics in space reported by University of Colorado researchers

...ntal due to relatively high toxicity levels. The modification of the apparatus containing the antibiotic experiments for the flight appears to have made a difference, said Klaus. "We added a new gas-exchange fermentation device, which appears to have stimulated the antibiotic production by 20-fold over the tes...

Aerosol pollutants in atmosphere likely masking global warming

...ht back to space. Toon, who has studied similar modification of clouds over the ocean and their effects, said aerosol particulates in the atmosphere are reflecting sunlight back into space, directly cooling Earth. The new findings by Rosenfeld are more evidence that aerosol-cloud processes may be diluting and...

New findings on genetically modified plants and foods

...ibed for allergens in biotech plants: The genetic modification of crops carries the potential for the transfer of allergens because the process introduces one or more new, novel proteins into foods. (All allergens are proteins, but only a few of the proteins found in nature are allergenic.) Nebraska researchers ...

Chemical receptor key to fetal development

...s for learning and memory," Dr. Poon said. "If the modification lasts for a long time, you remember!" Because it is so involved in this process, the NMDA receptor has been of interest to scientists studying learning and memory. To that end, a few years ago MIT biology professor and Nobel laureate Susumu Tonegawa ...

Memory mechanism found at nerve cell connections in the brain

...mammals that when synapses change, the modification depends on new proteins created specifically at the site." This synaptic chemical activity is an efficient way for the brain to make new proteins and change existing ones rapidly, Huber said. "The mechanism appears to be a vi...

UNC opens first clinical trial of vaccine treatment for advanced breast cancer

...s is the first use of a vaccine directed against a modification of a specific part of the HER-2/neu protein found on breast cancer cells," he added. People have tried using engineered proteins in the treatment of melanoma but not for breast cancer." A breast cancer patient from Rochester, New York, is scheduled f...

Inheritable gene modification research should not proceed on humans without standards and oversight, AAAS report says

...h the potential benefits of human inheritable gene modification (IGM) and the significant concerns about it. Recently, researchers announced credible success in improving patient health through somatic (non-inheritable) gene therapy, signaling that years of research are about to bear fruit. Theoretically, modify...

The site has...

Nanogen reports progress in development of electronic technology for high-throughput screening of protein kinases

...r 10% of cellular proteins are subject to covalent modification via phosphorylation. Protein kinases are particularly important in signal transduction pathways, and kinase dysfunction is thought to contribute to many forms of cancer. At Screentech 2001, Nanogen presented its progress towards developing different...
