First cigarette "buzz", addiction linked to gene

Anyone who has ever tried smoking probably remembers that first cigarette vividly. For some, it brought a wave of nausea or a nasty coughing fit. For others, those first puffs also came with a rush of pleasure or "buzz."

Discovery of obesity genes

A study of 228 women has revealed genetic variants responsible for body shape. Based on work in the fruit fly Drosophila melanogaster, research published in the open access journal BMC Genetics identifies natural variation in the human LAMA5 gene as a key determinant of weight.

BioNanomatrix awarded NIH grant for nanoscale platform for single-molecule DNA mapping

BioNanomatrix, Inc. has announced receipt of a grant from the National Human Genome Research Institute of the U.S. National Institutes of Health (NIH). Under the direction of BioNanomatrix principal investigator Dr. Ming Xiao, the two-year $399,020 project will develop a nanoscale platform for single-molecule haplotyping imaging and analysis of long strands of DNA at ultra-high resolution in a massively parallel format.

Genetic biomarker linked to subcutaneous growth hormone dose-response

The interindividual variability of response to subcutaneously applied protein-based drugs remains poorly understood. However, defining genetic markers that can be associated with biological effects of such drugs may improve the understanding of individual variability of response and even drug resistance.

Recipe for cell reprogramming adds protein

A drug-like molecule called Wnt can be substituted for the cancer gene c-Myc, one of four genes added to adult cells to reprogram them to an embryonic-stem-cell-like state, according to Whitehead researchers.

Oestrogen - a beneficial addition to treatment of schizophrenia in women

Australian scientists have found that women suffering from schizophrenia were less likely to suffer hallucinations or delusions, when the hormone oestrogen was added to their treatment.

Testosterone and body fat are controlled by the same genes

Genes that control percentage of body fat are also responsible for circulating levels of testosterone in men, research published in the latest edition of Clinical Endocrinology shows. The research shows a 23% overlap between the genes that control testosterone and those that regulate body fat composition, suggesting that these two variables are partly controlled by the same set of genes.

Genetic discovery may lead to new blood test for people at high risk for cancer

Research funded in part by the Canadian Cancer Society may lead to a genetic screening test that could help families who are at high risk for cancer.

Scientists discover link between DNA copy number changes and cancer risk

Scientists at The Hospital for Sick Children (SickKids) have discovered a link between a newly discovered form of inherited genetic alteration, termed DNA copy number variation (CNV), and cancer susceptibility.

First NY to LA living-donor transplant chain results in three lifesaving kidney transplants at UCLA

The lives of three Los Angeles-area kidney transplant patients were transformed by one of the West Coast's first three-way living donor kidney transplant chains, made possible through the generosity of a non-directed, altruistic kidney donor from New York City -- announced today at a joint news conference.

Anti-reflux surgery - research may lead to changes in treatment recommendations

Researchers at Wake Forest University Baptist Medical Center have found that the reflux and swallowing problems that are common symptoms in patients with Rett syndrome and other neurological impairments, may be caused by a different mechanism than they are in healthy individuals. The finding leaves researchers to wonder if these patients truly benefit from anti-reflux surgery commonly performed in these children.

Exercise enhancing pill in the pipeline

A pill which could help people exercise for longer is in the pipeline but is sure to cause controversy as it can apparently deliver some of the benefits of exercise, even for those who do not move a muscle.

Immunotherapy shows promise in high-risk pediatric sarcomas

Based on a pilot study in children with sarcoma, researchers at the National Institutes of Health (NIH) believe that immunotherapy could prove beneficial in treating high-risk forms of this cancer.

Genetic defect in skin cells leads to neurodermatitis, hay fever and asthma

New knowledge points to the fact that a genetically induced lack of filaggrin, a key protein of the skin barrier, plays a decisive role in the origin of allergies.

Inherited form of hearing loss stems from gene mutation

Pat Phalin learned she had hearing loss at 30, when she volunteered to give hearing tests at her local school. The pupils heard sounds she could not hear.

Experimental drug turns lab mice into long-distance runners

Trying to reap the health benefits of exercise? Forget treadmills and spin classes, researchers at the Salk Institute for Biological Studies may have found a way around the sweat and pain. They identified two signaling pathways that are activated in response to exercise and converge to dramatically increase endurance.

Monkey virus found in people living and working with monkeys

A research team led by University of Washington scientists has found that several people in South and Southeast Asian countries working and living around monkeys have been infected with simian foamy virus (SFV), a primate virus that, to date, has not been shown to cause human disease.
