Infectious Virus Hidden In Chromosomes During Latency Can Be Passed From Parents To Children
Human herpesvirus 6 (HHV-6) infects nearly 100 percent of humans in early childhood, and the infection then lasts for the rest of a person's life...
Dietary Supplements Discouraged For Prostate Cancer Patients
Prostate-specific dietary supplements should not be taken during radiation therapy treatments because they have been shown to increase the radiosensitivity of normal prostate cell lines, leading to normal tissue complications, according to a study in the March issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society ...
Stem Cells Of Humans And Mice Differ More Strongly Than Suspected: New Study Calls Research Factors Into Question
They are considered to be the most important model organism for research into human biology: mice may look totally different, but they are in many ways similar to Homo sapiens on a fundamental level. For instance, an impressive 99 per cent of the mouse genes are matched by a corresponding sequence in the human genome...
Unselfish Molecules May Have Helped Give Birth To The Genetic Material Of Life
One of the biggest questions facing scientists today is how life began...
Is Prenatal Screening For Rare Diseases Like Spinal Muscular Atrophy Too Costly?
Spinal Muscular Atrophy (SMA) is one of many serious disorders for which prenatal testing is available. SMA affects approximately 1 in 10,000 live births and is the leading genetic cause of infant mortality and the second most common autosomal recessive disorder, after cystic fibrosis...
Improvements Needed In Genomic Test Result Discussions
One in three early stage breast cancer patients who received genomic testing when deciding about treatment options felt they did not fully understand their discussions with physicians about their test results and their risk of the disease recurring, a new study has found...
Improvements Needed In Genomic Test Result Discussions
A new study has found that one in three early-stage breast cancer patients who received genomic testing when deciding about treatment options felt they did not fully understand their discussions with physicians about their test results and their risk of recurrence. About one in four experienced distress when receiving their test results...
Max Planck Scientists Develop A Fingerprint For Genes: New Strategy To Play Major Role In Research On Human Diseases
Cells may not have a mouth, but they still need to ingest substances from the external environment. If this process - known as endocytosis - is affected, it can lead to infectious diseases or cardio-vascular diseases, cancer, Huntington's and diabetes...
Enobia Pharma Taps McGill Expertise In Developing First Effective Treatment For Rare Genetic Disorder
Dr. Marc McKee, of McGill's Faculty of Dentistry and the Department of Anatomy and Cell Biology, is collaborating closely with Enobia Pharma Inc, a Quebec biotech company, to develop innovative treatments for serious genetic bone diseases. McKee's research looks into the reasons why calcium-phosphate mineral fails to crystallize properly to form strong bones and teeth...
Food Allergy-Related Disorder Linked To Master Allergy Gene
WHAT: Scientists have identified a region of a human chromosome that is associated with eosinophilic esophagitis (EoE), a recently recognized allergic disease. People with EoE frequently have difficulty eating or may be allergic to one or more foods. This study further suggests that a suspected so-called master allergy gene may play a role in the development of this rare but debilitating disorder...
In Stanford Study Mathematical Innovation Turns Blood Draw Into Information Gold Mine
Scientists at the Stanford University School of Medicine have devised a software algorithm that could enable a common laboratory device to virtually separate a whole-blood sample into its different cell types and detect medically important gene-activity changes specific to any one of those cell types...
New Sensor Array Detects Single Molecules For The First Time
MIT chemical engineers have built a sensor array that, for the first time, can detect single molecules of hydrogen peroxide emanating from a single living cell...
Gene Site Found For A Children's Food Allergy
Pediatrics researchers have identified the first major gene location responsible for a severe, often painful type of food allergy called eosinophilic esophagitis (EoE). In this disease, which may cause weight loss, vomiting, heartburn and swallowing difficulties, a patient may be unable to eat a wide variety of foods...
New Insights On A Fundamental DNA Repair Mechanism
Adding a new link to our understanding of the complex chain of chemistry that keeps living cells alive, a team of researchers from the University of Vermont (UVM), the University of Utah, Vanderbilt University and the National Institute of Standards and Technology (NIST) has demonstrated for the first time the specific activity of the protein NEIL3, one of a group responsible f...
First-Of-Its-Kind Project Will Sequence Difficult Breast Cancers To Provide Insight Into Treatment Strategies
Life Technologies Corporation (NASDAQ: LIFE) has announced that it is collaborating with the Translational Genomics Research Institute (TGen) and US Oncology to sequence the genomes of 14 patients afflicted with triple negative breast cancer whose tumors have progressed despite multiple other therapies...
'Evolutionary Biologist' Studies The Co-Evolution Of Humans And Diseases
Harmit Singh Malik, Ph.D., an evolutionary biologist at Fred Hutchinson Cancer Research Center, has received the 2010 Vilcek Prize for Creative Promise in Biomedical Science. He received the honor, which carries a $25,000 cash prize, for his research on the co-evolution of humans and diseases. The annual Vilcek Foundation awards celebrate "immigrant achievement in biomedical science and arts...
Virus Infections May Be Contributing Factor In Onset Of Gluten Intolerance
A research project in the Academy of Finland's Research Programme on Nutrition, Food and Health (ELVIRA) has brought new knowledge on the hereditary nature of gluten intolerance and identified genes that carry a higher risk of developing the condition...
2010 Yeast Genetics And Molecular Biology Meeting
The Genetics Society of America is pleased to announce the 2010 Yeast Genetics and Molecular Biology Meeting, July 27-August 1, 2010, at the University of British Columbia (UBC) in Vancouver, Canada. This biennial meeting brings together investigators studying various aspects of eukaryotic biology in yeast...
2 Teams Advance On Answers To TB Epidemic By Going 'Back To The Drawing Board'
When people get exposed to the mycobacterium responsible for tuberculosis (TB), some will become sick with a disease that is a major cause of mortality around the world while others simply don't...
Naegleria Genome Sheds Light On Transition From Prokaryotes To Eukaryotes
In the long evolutionary road from bacteria to humans, a major milestone occurred some 1.5 billion years ago when microbes started building closets for all their stuff, storing DNA inside a nucleus, for example, or cramming all the energy machinery inside mitochondria...
Link Between Vitamin D And Skin Cancer
A Henry Ford Hospital study has shown a link between Vitamin D levels and basal cell carcinoma, a finding that could lead researchers to better understand the development of the most common form of skin cancer...
Genetic Cause Discovered For Rare Bleeding Disorder
For some Canadians, any cut such as from dental work or surgery can cause days or more of bleeding. Although they are not hemophiliacs, for some an ordinary bruise can balloon into the size of an orange. For others, knees, elbows and ankles are crippled when bleeding seeps into joints. In very serious cases, hundreds of blood transfusions are required for recovery...
Discovery Of Gene That Affects Susceptibility To TB And Clues To How It Works
University of Washington (UW) researchers have identified a gene involved in susceptibility and resistance to tuberculosis. This same gene, they have found, has a role in the severity of leprosy, which is caused by a related pathogen. The researchers also have learned why this gene is important for susceptibility...
