Ordinary Heart Cells Become "Biological Pacemakers" With Injection Of A Single Gene
Cedars-Sinai Heart Institute researchers have reprogrammed ordinary heart cells to become exact replicas of highly specialized pacemaker cells by injecting a single gene (Tbx18)-a major step forward in the...
A Purdue University biochemist has determined the function of a gene that when mutated leads to a genetic variation of amyotrophic lateral sclerosis, or Lou Gehrig's disease. James Clemens, an assistant professor of biochemistry, found that a gene called VAPB is responsible for transporting...
Lung cancer researchers at St. Joseph's Hospital and Medical Center in Phoenix, Ariz., in collaboration with researchers at the Translational Genomics Research Institute and other institutions, have identified a gene that plays a role in the growth and spread of non-small cell lung cancer...
By linking 15 new genetic regions to coronary artery disease, a large international study sheds new light on the underlying causes of this most common form of heart disease, which results from the build up of fatty material or plaque on the insides of the blood vessels of the heart. One...
Reading the headlines of web articles about this obesity and depression study is like*witnessing a game of "telephone" between narcissists, idiots and sociopaths. Oof. A truly stunning*example of how health studies get distorted in the media. More »

An international research team including scientists from the University of Toronto's Faculty of Medicine has discovered a link between a mutation in an immune system gene and Alzheimer's disease. Using data from 25,000 people, researchers from the Faculty of Medicine and University College...
Preliminary findings from the first trial of a new drug for patients with mesothelioma show that it has some success in preventing the spread of the deadly disease in patients lacking an active tumour suppressor gene called NF2. The study is presented at the 24th EORTC-NCI-AACR [1] Symposium on...
A gene that is associated with regeneration of injured nerve cells has been identified by scientists at Penn State University and Duke University. The team, led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn State, has found that a mutation in a single...
University of South Florida researchers have identified a genetic biomarker for age-related hearing loss, a major breakthrough in understanding and preventing a condition of aging that affects 30 million Americans and greatly diminishes their quality of life. In a nine-year study that was a...
Researchers at Moffitt Cancer Center have discovered a unique immune gene signature that can predict the presence of microscopic lymph node-like structures in metastatic melanoma. The presence of these immune structures, the researchers said, appears to be associated with better survival and may...
It has long been known that breast density, or mammographic density, is a strong risk factor for breast cancer, and that estrogen and progestin hormone therapy increases dense breast tissue. Now, a study published in BioMed Central's open access journal Breast Cancer Research has identified...
Decreased activity of a group of genes may explain why in young children the "fear center" of the anxious brain can't learn to distinguish real threats from the imaginary, according to a new University of Wisconsin study. The study, published in the Proceedings of the National Academy of...
A single genetic variant in kidney donors' cells may help determine whether their transplanted organs will survive long term, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings provide new information that might be used...
Scientists at the Montreal Neurological Institute and Hospital - The Neuro, McGill University working with a team at Oxford University have uncovered the genetic defect underlying a group of rare genetic disorders. Using a new technique that has revolutionized genetic studies, the teams...
New insights into sperms' swimming skills shed light on male infertility, which affects one in 20 men, and could provide a new avenue to the development of a male contraceptive pill. In a study published in the journal PLoS Genetics, researchers from Monash University, the University of...
Researchers from Queen Mary, University of London have developed a new gene test that can detect pre-cancerous cells in patients with benign-looking mouth lesions. The test could potentially allow at-risk patients to receive earlier treatment, significantly improving their chance of survival...
The X Factor*trucks rolled through Providence, R.I., tonight, for what we first thought would be a bust. After giving out more noes than we could count, L.A. Reid, Britney Spears,...
Scientists have restored the sense of smell in mice through gene therapy for the first time -- a hopeful sign for people who can't smell anything from birth or lose it due to disease. The achievement in curing congenital anosmia -- the medical term for lifelong inability to detect odors -- may...
Two opposing teams battle it out to regulate gene expression on the DNA playing field. One, the activators, keeps DNA open to enzymes that transcribe DNA into RNA. Their repressor opponents antagonize that effort by twisting DNA into an inaccessible coil around histone proteins, an amalgam...
