Astrocytes appear to retaliate against AD

When brain cells start oozing too much of the amyloid protein that is the hallmark of Alzheimer's disease, the astrocytes that normally nourish and protect them deliver a suicide package instead, researchers report.

Researchers identify genetic marker linked with smoking quantity in African Americans

In a step toward understanding possible genetic differences in smoking behaviors, a team of researchers co-led by SRI International has identified a genetic marker associated with smoking quantity in people of African ancestry.

Intermountain signs collaborative research agreement with Myriad

Intermountain Healthcare and Myriad Genetics today announced they have signed a collaborative research agreement. The purpose of this agreement is to perform research and validation studies on transformative molecular diagnostic tests being developed by Myriad in an effort to improve the care and treatments for patients at Intermountain and around the world.

Some patients appear to be more predisposed for recurrent infection from C. diff

University of Cincinnati (UC) researchers have found that some patients appear to be more predisposed for recurrent infection from the bacterium Clostridium difficile, or C. diff, and that it may advance to a more serious inflammatory condition in those individuals.

MGH develops new technique to reconstruct the larynx after surgery for advanced cancer

Massachusetts General Hospital (MGH) surgeons have developed a new technique for reconstructing the larynx after surgery for advanced cancer.

Human cytomegalovirus associated with neovascular AMD

A team of researchers, including a scientist from the Viral Immunology Center at Georgia State University, have found that a type of herpesvirus infection of the eye is associated with neovascular age-related macular degeneration (AMD), a disease that causes blindness in the elderly.

Deletion of 'lunatic fringe' promotes tumor formation of basal-like breast cancers

Multiple research projects - including a 2006 study conducted at the University of North Carolina at Chapel Hill - have used DNA microarray analysis to identify several breast cancer subtypes, including luminal A, luminal B, basal-like and HER2-enriched.

Study uncovers distinct subtype of prostate cancer

A collaborative expedition into the deep genetics of prostate cancer has uncovered a distinct subtype of the disease, one that appears to account for up to 15 percent of all cases, say researchers at Weill Cornell Medical College, the Broad Institute of MIT and Harvard and the Dana-Farber Cancer Institute.

Prenatal Diagnosis publishes Sequenom CMM’s MaterniT21 PLUS LDT clinical study

Sequenom, Inc., a life sciences company providing innovative genetic analysis solutions, today announced that a new publication from the large Women & Infants multi-center clinical study on the Sequenom Center for Molecular Medicine's (Sequenom CMM) MaterniT21 PLUS laboratory-developed test (LDT) has been published online in the peer-reviewed journal, Prenatal Diagnosis.

Large survey of genetic variation offers insights into human diseases

A large survey of human genetic variation, published today in the online version of the journal Science, shows that rare genetic variants are not so rare after all and offers insights into human diseases.

Personal genetic test results does not drive overuse of expensive medical care

People have increasing opportunities to participate in genetic testing that can indicate their range of risk for developing a disease. Receiving these results does not appreciably drive up or diminish test recipients' demand for potentially costly follow-up health services, according to a study performed by researchers at the National Institutes of Health and colleagues at other institutions.

Rare DNA variations may be responsible for differences in susceptibility to common disorders

One-letter switches in the DNA code occur much more frequently in human genomes than anticipated, but are often only found in one or a few individuals. The abundance of rare variations across the human genome is consistent with the population explosion of the past few thousand years, medical geneticists and evolutionary biologists report in the May 17 advanced online edition of Science.

Personal genetic test results don't drive overuse of expensive medical care

People have more and more chances to participate in genetic testing that can indicate their range of risk for developing a disease. Receiving these results does not appreciably drive up- or diminish-test recipients' demand for potentially costly follow-up health services, according to a new study in the May 17, 2012 early online issue of Genetics in Medicine.

Regular eating times, extended daily fasting may prevent diabetes, obesity

It turns out that when we eat may be as important as what we eat. Scientists at the Salk Institute for Biological Studies have found that regular eating times and extending the daily fasting period may override the adverse health effects of a high-fat diet and prevent obesity, diabetes and liver disease in mice.

Researchers identify novel base modification in RNA

Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics that DNA consists of only four bases.

Researchers sequence genomes of 21 breast cancers

In two back-to-back reports published online on 17 May in Cell, researchers have sequenced the genomes of 21 breast cancers and analysed the mutations that emerged during the tumours' development. The individual results are described below.

Researchers identify 57 SNPs associated with autism

By focusing on the identification of common genetic variants, researchers have identified 57 single nucleotide polymorphisms (SNPs) that predict-with a high degree of certainty--the risk that siblings of children with Autism Spectrum Disorder (ASD) will also develop the condition. The findings were presented at the International Meeting for Autism Research.

Breast cancer cell surface protein blows cover of potent tumor-generating cells

Breast cancer stem cells wear a cell surface protein that is part nametag and part bull's eye, identifying them as potent tumor-generating cells and flagging their vulnerability to a drug, researchers at The University of Texas MD Anderson Cancer Center report online in Journal of Clinical Investigation.
