Gene Therapy for Skin Disease Produces Long-Term Benefits

December 27, 2013 11:10 am | News | Comments

In a new study, researchers evaluated a patient with a genetic skin disorder known as epidermolysis bullosa (EB) nearly seven years after he had undergone a gene therapy procedure as part of a clinical trial. The study revealed that a small number of skin stem cells transplanted into the patient's legs were sufficient to restore normal skin function, without causing any adverse side effects.

Concussions May Be Related to Alzheimer's Plaque Buildup

December 27, 2013 10:31 am | News | Comments

A new study suggests that a history of concussion involving at least a momentary loss of consciousness may be related to the buildup of Alzheimer's-associated plaques in the brain. The research is published in the Dec. 26, 2013, online issue of Neurology, the medical journal of the American Academy of Neurology.

Antioxidant Drug Knocks Down MS-Like Disease in Mice

Researchers at Oregon Health & Science University have discovered that an antioxidant designed by scientists more than a dozen years ago to fight damage within human cells significantly helps symptoms in mice that have a multiple sclerosis-like disease. 

Potential Therapeutic Target for Rare Soft-Tissue Cancer Identified

December 27, 2013 9:30 am | News | Comments

In the study, published online in Cell Reports, scientists found that inhibiting the action of a protein called BRD4 caused cancer cells to die in a mouse model of malignant peripheral nerve sheath tumors (MPNSTs). Learn more...

Toys, Books, Cribs Harbor Bacteria for Long Periods, Study Finds

December 27, 2013 9:15 am | News | Comments

University at Buffalo research published today in Infection and Immunity shows that Streptococcus pneumoniae and Streptococcus pyogenes do persist on surfaces for far longer than has been appreciated. The findings suggest that additional precautions may be necessary to prevent infections, especially in settings such as schools, daycare centers and hospitals.

Molecule Associated with Kawasaki Disease Discovered

December 27, 2013 9:06 am | News | Comments

Sanford-Burnham Medical Research Institute scientists have discovered a new molecule that forms when certain white blood cells—macrophages—are stimulated in response to pathogens. The molecule, termed "THRIL," helps regulate the immune response and shows an association with Kawasaki disease.

Genetic Marker Predicts Susceptibility to H7N9 Bird Flu

December 26, 2013 12:07 pm | News | Comments

Published in the Journal Proceedings of the National Academy of Sciences, senior author, Associate Professor Katherine Kedzierska from the Department of Microbiology and Immunology said that being able to predict which patients will be more susceptible to the emerging influenza strain, will allow clinicians to better manage an early intervention strategy.

Low Oxygen Conditions Promote Breast Cancer Spread

December 26, 2013 11:40 am | News | Comments

Biologists at The Johns Hopkins University have discovered that low oxygen conditions, which often persist inside tumors, are sufficient to initiate a molecular chain of events that transforms breast cancer cells from being rigid and stationery to mobile and invasive. 

First Structure of Enzyme that Removes Methylation Obtained

December 26, 2013 11:28 am | News | Comments

Scientists have obtained the first detailed molecular structure of a member of the Tet family of enzymes. The finding is important for the field of epigenetics because Tet enzymes chemically modify DNA, changing signposts that tell the cell's machinery "this gene is shut off" into other signs that say "ready for a change."

Systematic, Genomic Study of Cervical Cancer Completed

December 26, 2013 11:19 am | News | Comments

Researchers from the Boston area, Mexico and Norway have completed a comprehensive genomic analysis of cervical cancer in two patient populations. The study identified recurrent genetic mutations not previously found in cervical cancer, including at least one for which targeted treatments have been approved for other forms of cancer.

New Genetic Risk Factor for Type 2 Diabetes Revealed

December 26, 2013 11:03 am | News | Comments

An international team of researchers in Mexico and the United States has uncovered a new genetic clue that contributes to an increased risk of developing type 2 diabetes, particularly the elevated risk among Mexican and other Latin American populations.

Molecular Markers Used to Assess Early Sciatic Nerve Injury

December 26, 2013 10:51 am | News | Comments

Substance P and calcitonin gene-related peptide are the main neuropeptides in peripheral nerve ganglia, which can anterogradely transmit nociceptive information to the central nervous system. Findings published in Neural Regeneration Research  suggest that these neuropeptides may possibly serve as an index for evaluating early peripheral nerve injury.

Study Shows Where Alzheimer's Starts, How It Spreads

December 23, 2013 11:40 am | News | Comments

Using high-resolution functional MRI (fMRI) imaging in patients with Alzheimer's disease and in mouse models of the disease, Columbia University Medical Center (CUMC) researchers have clarified three fundamental issues about Alzheimer's: where it starts, why it starts there and how it spreads. In addition to advancing understanding of Alzheimer's, the findings could improve early detection of the disease. Learn more...

New, Reversible Cause of Aging Discovered

December 20, 2013 12:29 pm | News | Comments

Researchers have discovered a cause of aging in mammals that may be reversible. The essence of this finding is a series of molecular events that enable communication inside cells between the nucleus and mitochondria.          

Study IDs, Breaks Down 'Wall' Around Tumors

December 20, 2013 12:12 pm | News | Comments

Researchers have identified how the ‘wall’ around cancer tumors functions and how to break it down, enabling the body’s own defenses to reach and kill the cancer cells within.                     

Drug-resistant E. Coli Emerged from Single Strain of Bacteria

December 20, 2013 11:57 am | News | Comments

Virulent, drug-resistant forms of E. coli that have recently spread around the world emerged from a single strain of the bacteria– not many different strains, as has been widely supposed.                     

One Step Closer to a 'Universal' Flu Vaccine
