Scientists uncover new genes responsible for cancer, deafness

From deep within the genomes of organisms as diverse as plants, worms and yeast, scientists have uncovered new genes responsible for causing human diseases such as cancer and deafness.

Researchers invent zinc-stapled insulin to reduce insulin-related cancer risk

For millions of Americans with Type-2 diabetes and inject insulin to control diabetes (with onset typically in adulthood) the associated risk of cancer is of increasing concern. Studies have demonstrated that obesity and excess insulin - whether naturally produced by the body or injected in synthetic form - are associated with an increased incidence of some common cancers.

Stress hormones may suppress tumor growth: Study

Chronic stress triggers a chain of molecular events that protects breakaway ovarian cancer cells from destruction, a team of researchers led by scientists at The University of Texas M. D. Anderson Cancer Center reports April 12 in the early online publication of the Journal of Clinical Investigation.

Gilead Sciences doses first patient in Quad Phase III clinical program

Gilead Sciences, Inc. today announced that it has dosed the first patient in the Phase III clinical program evaluating its investigational fixed-dose, single-tablet "Quad" regimen of elvitegravir, cobicistat (formerly GS 9350), emtricitabine and tenofovir disoproxil fumarate.

Researchers report major step forward in effort to understand and engineer protein structure

Researchers in Singapore are reporting this week that they have gleaned key insights into the architecture of a protein that controls iron levels in almost all organisms. Their study culminated in one of the first successful attempts to take apart a complex biological nanostructure and isolate the rules that govern its natural formation.

Scientists identify specific mechanism that triggers resistance to vancomycin

A new study led by the scientific director of the Michael G. DeGroote Institute for Infectious Disease Research has uncovered for the first time how bacteria recognize and develop resistance to a powerful antibiotic used to treat superbug infections.

Ku protein employs unique mechanism for DNA repair: Researchers

Scientists have shown in multiple contexts that DNA damage over our lifetimes is a key mechanism behind the development of cancer and other age-related diseases. Not everyone gets these diseases, because the body has multiple mechanisms for repairing the damage caused to DNA by aging, the environment and other human behaviors - but the mechanisms behind certain kinds of DNA repair have not been well-understood.

Effective compound against antibiotic-resistant biofilms

Researchers at North Carolina State University have found a chemical compound that, when used in conjunction with conventional antibiotics, is effective in destroying biofilms produced by antibiotic-resistant strains of bacteria such as the Staphylococcus strain MRSA and Acinetobacter. The compound also re-sentsitizes those bacteria to antibiotics.

Drugs that affect methylation state of genes could reverse autism's effects: The FASEB Journal

A new discovery raises hope that autism may be more easily diagnosed and that its effects may be more reversible than previously thought. In a new study appearing online in The FASEB Journal, scientists have identified a way to detect the disorder using blood and have discovered that drugs which affect the methylation state of genes could reverse autism's effects.

New methodology helps investigate unfolding of DNA

NYU Langone Medical Center researchers have developed a powerful new method to investigate the discrete steps necessary to turn on individual genes and examine how the process goes wrong in cancer and other diseases. The finding, based on seven years of research and described in the April 9 issue of Molecular Cell, allows scientists to investigate the unfolding of DNA, a process required for gene activation.

Researchers show iRGD peptide increases treatment efficacy against cancer

Researchers have shown that a peptide (a chain of amino acids) called iRGD helps co-administered drugs penetrate deeply into tumor tissue. The peptide has been shown to substantially increase treatment efficacy against human breast, prostate and pancreatic cancers in mice, achieving the same therapeutic effect as a normal dose with one-third as much of the drug.

Single vaccine for anthrax and plague: iBio confirms grant of rights

iBio, Inc. confirmed today the grant of rights to use iBio's proprietary technology, the iBioLaunch™ platform, in support of a $5.3 million government-funded project for the development of a single vaccine to protect against both anthrax and plague. The project will be managed by Fraunhofer USA Center for Molecular Biotechnology (CMB) pursuant to the long-term agreement between iBio and CMB for advancement of the iBio technology.

Study: 75% of men with diabetes will develop some degree of ED

Erectile dysfunction is one of the most prevalent diabetes-induced complications in men; current estimates suggest that as many as 75% of men with diabetes will develop some degree of ED, and in many cases diabetics develop more severe forms of ED that are less responsive to standard drugs.

Cancer research at Georgia Tech: Report

Cancer treatment typically involves surgery, radiation therapy, chemotherapy, hormone therapy or biological therapy. An oncologist may use one therapy or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient's age and general health, and other factors.

Radius Health to develop lightweight X-ray emitter employing MAX technology at UCLA incubator space

While today many medical-imaging needs are being met with traditional vacuum tube-based technology, large segments of the X-ray-imaging market are poorly served, and there is widespread demand for both performance improvements and cost reductions.

New production method yields hundredsfold more ubiquitylated proteins critical for cancer research

Scientists at the University of Delaware have developed a new method for producing proteins critical to research on cancer, Alzheimer's, and other diseases.

Scientists create genetic map to identify mechanism behind heart abnormalities

Though heart disease is a major cause of disability and death, very little is understood about its genetic underpinnings. Recently, an international team of investigators at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA), Sanford-Burnham Medical Research Institute (Sanford-Burnham) and other organizations shed new light on the subject.

Combating immune suppressive cells in liver may prevent the spread of cancer: Study

Scientists have uncovered what could be a very important clue in answering one of the most perplexing questions about cancer: why does it spread to the liver more than any other organ? In a new research report published in the April 2010 issue of Journal of Leukocyte Biology, scientists from New York University describe experimental results suggesting that the immune system may be the reason.

RXi Pharmaceuticals reports net loss of 28% for 2009

RXi Pharmaceuticals Corporation, a biopharmaceutical company pursuing the development and commercialization of proprietary therapeutics based on RNA interference (RNAi), today reported financial results for the fourth quarter and year ended December 31, 2009.

High-fructose corn syrup makes rats fat: Princeton University study questioned

"HFCS makes rats fat? I can hardly believe that Princeton sent out a press release yesterday announcing the results of this rat study. The press release says: "Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same."
