Researchers discover three disease-causing genes in Salmonella

Researchers have discovered a novel mechanism in Salmonella that affects its virulence and its susceptibility to antibiotics by changing its production of proteins in a previously unheard of manner. This allows Salmonella to selectively change its levels of certain proteins to respond to inhospitable conditions.

Scientists identify new targets to develop treatment for HD

Scientists at the Buck Institute for Age Research have discovered that a particular family of enzymes are involved in the breakdown of proteins that modify the production of toxic fragments that lead to the pathology of Huntington's disease. These enzymes, matrix metalloproteinases, provide new targets for drug therapies for the disease - targets that have already been shown to respond to cancer drugs currently in clinical development.

Genetic interaction with diet causes variations in metabolic traits

Ever notice some people seem to eat anything they want and never gain a pound, while others seem to gain weight just by looking at fattening foods. You may be seeing things correctly after all. According to research published in the July 2010 issue of Genetics, this may have a biological cause. Using fruit flies, researchers have found that genes interacting with diet, rather than diet alone, are the main cause of variation in metabolic traits, such as body weight. This helps explain why some diets work better for some people than others, and suggests that future diets should be tailored to an individual's genes rather than to physical appearance.

The neck played major role in evolution of human brain: Study

By deciphering the genetics in humans and fish, scientists now believe that the neck - that little body part between your head and shoulders - gave humans so much freedom of movement that it played a surprising and major role in the evolution of the human brain, according to New York University and Cornell University neuroscientists in the online journal Nature Communications (July 27, 2010.)

Positive results from study with Genome Sequencer FLX System for HIV drug-resistant mutation detection

454 Life Sciences, a Roche Company, has announced promising new results from a multi-site collaborative research study which used the company's Genome Sequencer FLX System to perform HIV drug-resistant mutation detection.

Dopamine-releasing cells essential for detected odor to be associated with negative experience: Study

It is common sense that it's worth learning what things and situations are harmful to us if we want to have a long and healthy life. For example, after getting a nasty sunburn, we learn our lesson, and apply sun cream before going sunbathing next time. The importance of such learned avoidance strategies is reflected by the fact that even fruit flies possess them.

Iverson Genetic Diagnostics receives CMS approval for Warfarin clinical study

Iverson Genetic Diagnostics today announced the company has received approval from CMS to conduct a WARFARIN Clinical Study. The two-year (2) study will assess the impact of genetic information in calculating doses and the changes in the rate of adverse events when initiating Warfarin drug therapy. These changes will be compared against doses initiated without genetic data. The randomized and blinded, multi-center study will involve more than 7000 participants at over 50 sites nationwide.

Affymetrix releases new data for rapid design of custom arrays

Affymetrix, Inc.today announced that it has released an unparalleled data set based on extensive validation of novel SNPs from the 1000 Genomes Project. This data will give researchers access to more rare mutations for genome-wide association studies and will enable the rapid design of custom arrays for a variety of applications, including the validation of sequencing results.

Highlights on reasoning behind MRC's negative decision on funding of IVF

Thirty-two years ago today, the world's first baby was born after in vitro fertilisation. However, the work that led to the birth of Louise Brown on 25 July 1978 had to be privately funded after the UK's Medical Research Council decided in 1971 against providing the Cambridge physiologist Robert Edwards and the Oldham gynaecologist Patrick Steptoe with long-term financial support. Today, an intriguing paper published in Europe's leading reproductive medicine journal Human Reproduction reveals for the first time the reasoning behind the MRC's much-criticised decision.

HTG patients face increased risk for heart disease, stroke: Study

It can make blood look like cream of tomato soup. Patients with high levels of triglycerides in their blood, a disease called hypertriglyceridemia face an increased risk for heart disease and stroke. HTG affects one in 20 people in North America and is also associated with obesity, diabetes and pancreatitis. Most people now understand the importance of LDL, the bad cholesterol and HDL, the good cholesterol, to their overall health.

GRB7 gene drives an aggressive form of breast cancer, researchers find

Oregon Health & Science University Knight Cancer Institute researchers found that the GRB7 gene drives an aggressive form of breast cancer and acts independently of the HER-2 gene, known to be a stimulator of breast cancer growth. Isolating the role of this gene could ultimately help fine-tune a patient's treatment and enable physicians to provide a more accurate prognosis.

Repetition of DRD4 genotype may increase risk for extensive alcohol use

Your friend walks into a bar to meet you for happy hour. He sidles up to the bar and orders a drink - does that make you more likely to get a drink yourself? According to new findings reported in Psychological Science, a journal of the Association for Psychological Science, genetics may determine the extent to which you are influenced by social drinking cues - signals such as advertisements, drinks placed on a bar, and seeing other people around you drinking.

Bullied children are at risk for developing emotional problems

Bullying victimization is common among children of school age, although its consequences are often anything but benign. The recent death of a Massachusetts teen by suicide prompted state lawmakers to pass one of the most far-reaching anti-bullying laws within the U.S. Whether such legislative actions result in measurable decreases in physical or emotional distress among school peers remains to be seen.

Osteocalcin hormone can regulate glucose levels: Research

Researchers led by Columbia University Medical Center have discovered that the skeleton plays an important role in regulating blood sugar and have further illuminated how bone controls this process. The finding, published in Cell, is important because it may lead to more targeted drugs for type 2 diabetes.

Gene expression profiling may provide molecular diagnostic tool to diagnose depression

Blood tests have been extremely important tools aiding doctors in making medical diagnoses and in guiding the treatment of many diseases. However, psychiatry is one area of medicine where there are few diagnostic blood tests.New scientific fields may someday generate blood tests that can be used for these purposes. Some of the areas under increasingly intensive study are genetics, the study of variations in the genes that can be extracted from blood cells, and genomics like proteomics, the measurement of the levels of specific proteins in the blood, and gene expression profiling, which measures the levels of RNA produced from DNA as an indication of the level of the "activity" of particular genes.
