Researchers use retro approach to produce new drugs

This alternative approach to creating artificial organic molecules, called bioretrosynthesis, was first proposed four years ago by Brian Bachmann, associate professor of chemistry at Vanderbilt University. Now Bachmann and a team of collaborators report that they have succeeded in using the method to produce the HIV drug didanosine.

Faster DNA sequencing techniques more likely to improve care for patients with breast cancer

Faster and cheaper DNA sequencing techniques will likely improve care for patients with breast cancer but also create challenges for clinicians as they counsel patients on their treatment options.

CSP analogues may attenuate S. pneumoniae virulence, resistance

The spread of virulent, antibiotic-resistant strains of Streptococcus pneumoniae may be controllable through the use of competence-stimulating peptide analogues, US researchers believe.

Cumulative amount of specific gene products affects changes in cell fate, say researchers

Johns Hopkins biologists have discovered that when biological signals hit cells in rhythmic waves, the magnitude of the cells' response can depend on the number of signaling cycles — not their strength or duration. Because such so-called “oscillating signaling cycles” are common in many biological systems, the scientists expect their findings in single-celled organisms to help explain the molecular workings of phenomena such as tissue and organ formation and fundamental forms of learning.

DUF1220 protein domain also linked to severity of autism

The same gene family that may have helped the human brain become larger and more complex than in any other animal also is linked to the severity of autism, according to new research from the University of Colorado Anschutz Medical Campus.

FDA approves Xolair for treatment of chronic idiopathic urticaria

Genentech, a member of the Roche Group, today announced that the U.S. Food and Drug Administration approved Xolair (omalizumab) for the treatment of chronic idiopathic urticaria, a form of chronic hives.

CUMC researchers devise new system for classifying periodontal disease

Researchers at Columbia University Medical Center have devised a new system for classifying periodontal disease based on the genetic signature of affected tissue, rather than on clinical signs and symptoms. The new classification system, the first of its kind, may allow for earlier detection and more individualized treatment of severe periodontitis, before loss of teeth and supportive bone occurs.

People with rare inherited mutated gene have high chance of getting lung cancer

People who have an inherited mutation of a certain gene have a high chance of getting lung cancer — higher, even, than heavy smokers with or without the inherited mutation, according to new findings by cancer researchers at UT Southwestern Medical Center. Although both genders have an equal risk of inheriting the mutation, those who develop lung cancer are mostly women and have never smoked, the researchers found.

Study: Mood stabilizing drug may help prevent head and neck cancer

A new study indicates that a commonly used mood stabilizing drug may help prevent head and neck cancer. The study is published early online in Cancer, a peer-reviewed journal of the American Cancer Society.

Scientists develop unique cells to repair patient's defective and diseased bladder

For the first time, scientists have succeeded in coaxing laboratory cultures of human stem cells to develop into the specialized, unique cells needed to repair a patient's defective or diseased bladder.

Researchers uncover cause of rare type of ovarian cancer that strikes girls and young women

The cause of a rare type of ovarian cancer that most often strikes girls and young women has been uncovered by an international research team led by the Translational Genomics Research Institute, according to a study published online today by the renowned scientific journal, Nature Genetics.

Scientists explore link between SCN10A and cardiac arrhythmia risk

Although genome-wide association studies have linked DNA variants in the gene SCN10A with increased risk for cardiac arrhythmia, efforts to determine the gene's direct influence on the heart's electrical activity have been unproductive. Now, scientists from the University of Chicago have discovered that these SCN10A variants regulate the function of a different gene, SCN5A, which appears to be the primary gene responsible for cardiac arrhythmia risk.

Scientists unlock one of mysteries of modern genetics

Scientists at Indiana University have unlocked one of the mysteries of modern genetics: how acquired traits can be passed between generations in a process called epigenetic inheritance. The new work finds that cells don't know to silence some genes based on information hardwired into their DNA sequences, but recognize heritable chemical marks that are added to the genes. These chemical tags serve as a form of molecular memory, allowing cells to recognize the genes and remember to silence them again in each new generation.

Misplaced protein provides promising drug target for kidney cancer

The shortage of oxygen, or hypoxia, created when rapidly multiplying kidney cancer cells outgrow their local blood supply can accelerate tumor growth by causing a nuclear protein called SPOP-which normally suppresses tumor growth-to move out of the nucleus to the cytoplasm, where it has the opposite effect, promoting rapid proliferation.

Researchers identify steps by which cell removes RNA from cytoplasm

RNA encodes the proteins that play a key role in cellular reproduction, but the manner in which cells regulate its removal once these proteins are synthesized remains a mystery. One piece of this mystery has been solved as researchers at the University of North Carolina at Chapel Hill who have identified the steps by which a cell removes RNA from the cytoplasm.

NIH awarded five-year grant of up to $28 million to fight deadly Ebola virus

The National Institutes of Health (NIH) has awarded a five-year grant of up to $28 million to establish a new center for excellence to find an antibody "cocktail" to fight the deadly Ebola virus.

Researchers identify genetic defect that causes a subset of irritable bowel syndrome

Is irritable bowel syndrome (IBS) caused by genetics, diet, past trauma, anxiety? All are thought to play a role, but now, for the first time, researchers have reported a defined genetic defect that causes a subset of IBS. The research was published in the journal Gastroenterology.

NIH awards $28M grant to establish new center for excellence to find treatment for Ebola virus

The National Institutes of Health has awarded a five-year, $28 million grant to establish a new center for excellence to find an antibody "cocktail" to fight two types of viruses that cause severe hemorrhagic fever, including the deadly Ebola virus. The project involves researchers from 15 institutions, including Kartik Chandran, Ph.D., and Jonathan Lai, Ph.D., at Albert Einstein College of Medicine of Yeshiva University. Einstein will receive approximately $4 million of the total grant.

NSCLC gene fusion testing, targeted crizotinib – not yet cost effective

Genomic fusion testing for echinoderm microtubule-associated protein-like 4 and anaplastic lymphoma kinase genes plus targeted first-line crizotinib is not a cost effective treatment strategy for patients with advanced non-squamous non-small-cell lung cancer, shows a Canadian analysis.

New tool pinpoints genetic sources of disease

Many diseases are the result of either variations in the genome or reversible chemical changes to DNA, known as the epigenome. New data obtained by Johns Hopkins scientists show a connection between genetic variants and epigenetic information.
