MammaPrint more cost-effective and clinically-useful test than Oncotype DX

New research from University of the Sciences' Mayes College of Healthcare Business and Policy suggests that MammaPrint - a gene expression profiling (GEP) test used to identify whether women with early-stage breast cancer would benefit from chemotherapy - is the more cost-effective and clinically-useful test than the most frequently used GEP in practice in the United States today.

Adiponectin reduces depression-like symptoms in mice

A hormone with anti-diabetic properties also reduces depression-like symptoms in mice, researchers from the School of Medicine at the UT Health Science Center San Antonio reported today.

Viewpoints: Daschle says health law still has 4 hurdles; Commentators from states such as Calif., Texas and Florida wrestle with options

The GOP-controlled U.S. House plans to hold what can only be called symbolic votes on repealing the sweeping reforms they deride as "Obamacare." Meanwhile, at least 15 governors are said to be leaning toward refusing to expand state Medicaid programs -- a key part of the reform's strategy to provide some form of health insurance to the 32 million people now going without coverage.

Read-through molecule improves muscle function in DMD

A compound that results in a read-through on nonsense mutations in messenger RNA restores dystrophin expression in an animal model of Duchenne muscular dystrophy, research shows.

Gene defect linked to cluster of systemic complications

Research teams from The University of Texas Health Science Center at Houston (UTHealth) and Paris, France have discovered a gene defect linked to a cluster of systemic complications, including life-threatening thoracic aortic disease and intracranial aneurysms. The new syndrome is similar, but distinct from known syndromes such as Marfan and Loeys-Dietz syndrome.

Human immune response: TCD scientists make breakthrough which could lead to new drug therapies

A team of researchers at Trinity College Dublin’s School of Medicine has gained new insights into a protein in the human immune system that plays a key role in the protective response to infection and inflammation. The research findings have just been published in the internationally renowned peer-reviewed Journal of Biological Chemistry.

Does alcohol kill brain cells?

Several origins have been suggested for the idea that alcohol kills brain cells. Some link it to the temperance movement, which called for prohibition of alcohol.

Novel gene therapy approach may treat dysferlinopathies

The challenge of treating patients with genetic disorders in which a single mutated gene is simply too large to be replaced using traditional gene therapy techniques may soon be a thing of the past. A Nationwide Children's Hospital study describes a new gene therapy approach capable of delivering full-length versions of large genes and improving skeletal muscle function. The strategy may hold new hope for treating dysferlinopathies and other muscular dystrophies.

DNA from CF patients with and without chronic infections points to unsuspected mutation

Comparing the DNA from patients at the best and worst extremes of a health condition can reveal genes for resistance and susceptibly. This approach discovered rare variations in the DCTN4 gene among cystic fibrosis patients most prone to early, chronic airway infections.

Conference highlights utility of zebrafish for human disorder studies

Zebrafish, popular as aquarium fish, now have an important place in research labs as a model organism for studying human diseases.

Mouse model demonstrates role of AEG-1 in hepatocellular carcinoma

Researchers have created the first mouse model demonstrating the role of a cancer promoting gene, Astrocyte elevated gene-1 (AEG-1), in hepatocellular carcinoma, or liver cancer. The mouse model represents a critical step in understanding the molecular mechanisms of liver cancer progression and could lead to novel therapies for the disease.

Effect of spaceflight on C. elegans could help it to live longer

The effect of spaceflight on a microscopic worm - Caenorhabditis elegans (C. elegans) - could help it to live longer.

Presence of SPDEF protein may predict prostate cancers that are unable to metastasize

Prostate cancer doesn't kill in the prostate - it's the disease's metastasis to other tissues that can be fatal. A University of Colorado Cancer Center study published this week in the Journal of Biological Chemistry shows that prostate cancer cells containing the protein SPDEF continue to grow at the same pace as their SPDEF- cousins, but that these SPDEF+ cells are unable to survive at possible sites of metastasis.

Dynorphin plays an important role in weakening anxiety

Feelings of anxiety very effectively prevent people from getting into situations that are too dangerous. Those who have had a terrible experience initially tend to avoid the place of tragedy out of fear. If no other oppressive situation arises, normally the symptoms of fear gradually subside.

Protein AMPK protects sensory cells in the inner ear from permanent damage

If you're concerned about losing your hearing because of noise exposure (earbud deafness syndrome), a new discovery published online in the FASEB Journal offers some hope. That's because scientists from Germany and Canada show that the protein, AMPK, which protects cells during a lack of energy, also activates a channel protein in the cell membrane that allows potassium to leave the cell.

New epigenetic path toward a cure for osteoarthritis

In what could be a breakthrough in the practical application of epigenetic science, U.K. scientists used human tissue samples to discover that those with osteoarthritis have a signature epigenetic change (DNA methylation) responsible for switching on and off a gene that produces a destructive enzyme called MMP13.

FDA approves KRAS gene mutation test for colorectal cancer

The U.S. Food and Drug Administration today approved the first genetic test that can help some colorectal cancer (CRC) patients and their doctors determine if the drug Erbitux (cetuximab) would be an effective treatment based on the absence of a gene mutation. The therascreen KRAS RGQ PCR Kit can provide information about the KRAS gene mutation in patients whose CRC has spread to other parts of their body (metastasized).

New insights into role and importance of exosomes and their targeted gene transcripts

In the July 6 issue of Cell Stem Cell, researchers at the University of California, San Diego School of Medicine describe how human epidermal progenitor cells and stem cells control transcription factors to avoid premature differentiation, preserving their ability to produce new skin cells throughout life.

NewYork-Presbyterian/WCMC first in N.Y. City to offer INTRABEAM radiotherapy

NewYork-Presbyterian Hospital/Weill Cornell Medical Center is the first and only hospital in the five boroughs of New York City to offer women with early stage breast cancer INTRABEAM radiotherapy, an innovative radiation treatment delivered in a single dose at the time of surgery.
