New study could lead to new drugs to prevent premature birth

Dr Raheela Khan, of the University’s Academic Division of Obstetrics and Gynaecology based at the newly-opened University of Nottingham Medical School at Derby, is working with colleagues Dr Balwir Matharoo-Ball and Dr Dave Barratt in the University’s School of Pharmacy on the research looking at what makes some women go into labour before their baby is due.

A peptide called magainin, found in the skin of the African clawed frog, holds the secret to creating bacteria-killing surfaces

A peptide called magainin, first found in the skin of the African clawed frog, holds the secret to creating bacteria-killing surfaces, according to researchers at the University of Pennsylvania. The Penn scientists have taken a joint experimental-computational approach to mimicking magainin.

Researchers find new purpose for existing drugs to suppress colon cancer metastasis, secure post-radiation brain function, and trick tumors

Drugs approved for treatment of specific maladies sometimes show unexpected benefits. Researchers at the 95th annual meeting of the American Association for Cancer Research demonstrated highlighted how some drugs may one day offer previously unforeseen benefits for patients.

Enzyme called COX-2 may promote the development of ovarian tumors

Fox Chase Cancer Center scientists have identified how an enzyme called COX-2 may promote the development of ovarian tumors, adding further insight into the mechanism of COX-2 inhibitors and the prevention of this highly lethal disease. The data was presented today at the 95th Annual Meeting of the American Association for Cancer Research in Orlando, Fla.

Halting the development of certain pancreatic, ovarian, colon and lung cancers may be possible with new therapy

By investigating a single molecule that influences cell growth, a research group in the Purdue Cancer Center, including Brian S. Henriksen, has gained new insight into the chain of events that make some cancer cells divide uncontrollably, insight that may eventually lead to a way to break that chain, stopping cancer in its tracks. The molecule, known as Icmt, has a critical role in the development of Ras, an ordinarily beneficial protein that tells a cell to divide. The research group has determined how to inhibit Icmt's influence on Ras, without which the protein cannot develop effectively into an instigator of cell growth.

Discovery of molecule that is part of the machinery that mediates the sense of hearing

A group of scientists at The Scripps Research Institute, at the University of California in San Diego, and at the Oregon Hearing Research Center and Vollum Institute at Oregon Health & Science University have discovered a key molecule that is part of the machinery that mediates the sense of hearing.

p53 protein peptide stops cancer in its tracks

Researchers have dreamed of thwarting cancer by using proteins that halt cell growth and kill the tumor. In theory, the approach should work. In practice, however, scientists have not had an easy time of getting tumor suppressor proteins into cells where they can block growth effectively.

Supercomputer used to determine structures and functions of proteins

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are proposing to use a supercomputer originally developed to simulate elementary particles in high-energy physics to help determine the structures and functions of proteins, including, for example, the 30,000 or so proteins encoded by the human genome. Structural information will help scientists better understand proteins’ role in disease and health, and may lead to new diagnostic and therapeutic agents.

New Research Information on Tumor Necrosis Therapy

Researchers for Peregrine Pharmaceuticals presented today at the Strategic Research Institute’s Clinical-Stage Product Partnering Summit in La Jolla, CA a summary of clinical experience with Tumor Necrosis Therapy (TNT). The TNT technology is being developed in the U.S. and Europe by Peregrine under the trade name Cotara™. Over 200 patients have been treated with TNT world-wide and a TNT product has been approved to treat grade III or IV advanced lung cancer in the People’s Republic of China. A Cotara registration study for brain cancer has been approved by the U.S. Food and Drug Administration, and a Phase I colorectal cancer study is on-going at Stanford University Medical Center.

Stem cell research that could help diabetics

University of Florida adult stem cell experts have restored normal blood sugar levels in diabetic mice for three months by chemically coaxing bone marrow cells to produce insulin, a hormone normally made in the pancreas.

Breast feeding increases choline which means more brain cells

Five years ago, University of North Carolina at Chapel Hill researchers first reported finding that the nutrient choline played a critical role in memory and brain function by positively affecting the brain’s physical development. Differences in development influenced action, the scientists and their colleagues found. In animal experiments conducted at Duke University, both young and old rats performed significantly better on memory tasks if they received enough choline before birth compared with same-age rats whose mothers were fed choline-deficient diets. The latter showed deficits in the hippocampus and septums of their brains.
