Scientists uncover vast new gene regulatory network linked with cancer

Researchers at Columbia University Medical Center (CUMC) and two other institutions have uncovered a vast new gene regulatory network in mammalian cells that could explain genetic variability in cancer and other diseases.

Scientists reveal how resistance to hormone leptin develops

The effects of obesity - both on our bodies and on the health budget - are well known, and now, scientists are getting closer to understanding how the disease progresses, providing clues for future treatments.

Brain stem cell treatment for multiple sclerosis

The prospect of doing human clinical trials with stem cells to treat diseases like multiple sclerosis may be growing closer, say scientists at the University at Buffalo and the University at Rochester, who have developed a more precise way to isolate stem cells that will make myelin.

NextBio predicts mechanisms underlying drug toxicity and identifies new cancer biomarker

New research presented this week highlights the ability of NextBio to help life scientists and clinicians investigate publicly available genomic data to assess biological mechanisms underlying drug toxicity, as well as discover prospective cancer biomarkers for further validation.

Engineered HBLs could prevent deadly allergic reactions

Researchers from the University of Notre Dame have announced a breakthrough approach to allergy treatment that inhibits food allergies, drug allergies, and asthmatic reactions without suppressing a sufferer's entire immunological system.

Obese post-menopausal women outperform normal weight counterparts in cognitive tasks

Obesity has been associated with cognitive decline, characterized by a deterioration of mental abilities that involve memory, language, and thought-processing speed.

Study finds vitamin D is critical in human immune response to tuberculosis

"Vitamin D is needed to activate the immune system's response to tuberculosis (TB)," a finding that "could lead to new treatments for the lung disease," researchers from the University of California in Los Angeles (UCLA) said in a study published Wednesday in the journal Science Translational Medicine, Agence France-Presse reports.

Penn researchers demonstrate sound-processing deficits in mice brains with mutated dysbindin gene

Recent studies have identified many genes that may put people with schizophrenia at risk for the disease. But, what links genetic differences to changes in altered brain activity in schizophrenia is not clear. Now, three labs at the Perelman School of Medicine at the University of Pennsylvania have come together using electrophysiological, anatomical, and immunohistochemical approaches - along with a unique high-speed imaging technique - to understand how schizophrenia works at the cellular level.

Researchers identify gut bacteria bile acids linked to effectiveness of statin drugs in lowering cholesterol

Statins can be effective at lowering cholesterol, but they have a perplexing tendency to work for some people and not others. Gut bacteria may be the reason.

Researchers demonstrate that iPS stem cells may be used for gene therapy

This research, published on Oct. 12 on the Nature review website, provides evidence of a major concept could pave the way for the future use of these stem cells to treat humans, through perspective gene therapies.

Scientists characterize and isolate potential stem cells to treat MS, myelin disorders

Scientists have improved upon their own previous world-best efforts to pluck out just the right stem cells to address the brain problem at the core of multiple sclerosis and a large number of rare, fatal children's diseases.

Different molecular mechanisms in suprachiasmatic nucleus linked to jet lag differences

It's no secret that long-distance, west-to-east air travel - Seattle to Paris, for example - can raise havoc with a person's sleep and waking patterns, and that the effects are substantially less pronounced when traveling in the opposite direction.

ESCs express genes linked with early germ cell specification

Ordinarily, embryonic stem cells exist only a day or two as they begin the formation of the embryo itself. Then they are gone. In the laboratory dish, however, they act more like perpetual stem cells - renewing themselves and exhibiting the ability to form cells of almost any type, a status called totipotency.

AiC: Health Research receives U.S. Army grant for neuroimaging studies of human performance

The Arlington Innovation Center: Health Research (AiC: Health Research), of Virginia Tech's National Capital Region, has been awarded a $1.5 million cooperative research and development agreement from the U.S. Army for neuroimaging studies of human performance.

Study: Green vegetables boost immune function

Researchers reporting online in the journal Cell, a Cell Press publication, on October 13th have found another good reason to eat your green vegetables, although it may or may not win any arguments with kids at the dinner table.

Nature publishes Sangamo's gene correction strategy for A1AT deficiency

Sangamo BioSciences, Inc. (Nasdaq: SGMO) announced the publication of a preclinical study demonstrating highly specific, functional correction of the alpha 1-antitrypsin (A1AT) gene defect in patient-derived induced pluripotent stem cells (iPSCs) using zinc finger nucleases.

Survey analyses management of patients suffering from EGFRI toxicities

A recent survey of nurses from seven European countries, published in the peer-reviewed journal ecancermedicalscience, has analysed the management of patients suffering from toxicities due to treatment with epidermal growth factor receptor inhibitors.

BCL11A protein might serve as potential target for sickle cell disease

Flipping a single molecular switch can reverse illness in a model of sickle cell disease, according to a study by researchers at Children's Hospital Boston and Dana-Farber Cancer Institute. When turned off, the switch, a protein called BCL11A, allows the body to manufacture red blood cells with an alternate form of hemoglobin unaffected by the mutation that causes the disease.

Avita Medical introduces ReCell Spray-On Skin for chronic leg ulcers

Avita Medical Ltd., the regenerative medicine company, announced today that it has launched ReCell Spray-On Skin for the treatment of chronic leg ulcers, a market estimated at over US$1 billion.
