Early treatment stops epilepsy in its tracks

Yale School of Medicine researchers have shown for the first time that it is possible to suppress the development of epilepsy in genetically predisposed animals - which could open the door to treating epilepsy as a preventable disease.

Drug study for brain cancer shows promising results

A clinical study conducted at Henry Ford Hospital on the use of a drug to extend the survival of patients with the most common and aggressive type of brain cancer, has yielded results that were significantly better than expected.

Biocapture surfaces produced for study of brain chemistry

A research team at Penn State has developed a novel method for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules.

Why the switch stays on

Cellular processes, such as when to multiply, are often regulated by switches that control the frequency and timing of interactions between proteins.

Reprogrammed human adult stem cells rescue diseased muscle in mice

Scientists report that adult stem cells isolated from humans with muscular dystrophy can be genetically corrected and used to induce functional improvement when transplanted into a mouse model of the disease.

Protein fingerprinting made easy

Combining some traditional experimental methods of molecular biology with computational methods of artificial intelligence, a group of researchers from Ruder Boskovic Instititute and Faculty of Natural Sciences and Mathematics from Zagreb, Croatia, demonstrated a novel approach for producing 'protein fingerprints' of diverse tissues.

Odyssey Thera granted U.S. patent for animal imaging

Odyssey Thera, Inc. has announced that the United States Patent and Trademark Office granted U.S. Patent No. 7,306,914, entitled "Protein-fragment Complementation Assays (PCA) in whole animals: applications to drug efficacy, ADME, cancer biology, immunology, infectious disease and gene therapy.

More regulatory DNA than previously thought

Surrounding the small islands of genes within the human genome is a vast sea of mysterious DNA. While most of this non-coding DNA is junk, some of it is used to help genes turn on and off.

Losses of long-established genes contribute to human evolution

While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage.

Researchers advance stem cell gene therapy

Ireland Cancer Center of University Hospitals Case Medical Center researchers have recently made great strides in stem cell gene therapy research by transferring a new gene to cancer patients, via their own stem cells, with the ultimate goal of being able to use stronger chemotherapy treatment with less severe side effects.

Researchers find genetic switch for internal body clock

University of California, Irvine researchers have identified the chemical switch that triggers the genetic mechanism regulating our internal body clock.

Crimean Congo hemorrhagic fever virus strips away immune system's defensive measures

When the alert goes out that a virus has invaded the body, cells that have yet to be attacked prepare by "armoring" themselves for combat, attaching specific antiviral molecules to many of their own proteins to help resist the invader.

Secret lives of enzymes revealed

In a new study in Nature, Brandeis University Howard Hughes Medical Investigator Dr. Dorothee Kern and collaborators pull back the curtain on the secret lives of enzymes, the ubiquitous proteins that catalyze chemical reactions in the cell.

Cell trafficking finding may aid drug development

With findings highlighted on a recent cover of Developmental Cell , researchers at Weill Cornell Medical College in New York City have shed important new light on key trafficking mechanisms within epithelial cells. Epithelial cells line the outside of nearly all organs.

Biodegradable polymers with neurotransmitters promote nerve regrowth

Research reported December 11 in the journal Advanced Materials describes a potentially promising strategy for encouraging the regeneration of damaged central nervous system cells known as neurons.

Novel technique using computer modeling identifies potential side effects of pharmaceuticals

Early identification of adverse effects of drugs before they are tested in humans is crucial in developing new therapeutics, as unexpected effects account for a third of all drug failures during the development process.

Lethal human H5N1 influenza virus Replikin gene still upregulated

Replikins Ltd. has announced its latest findings regarding the virus replikin count in human H5N1 influenza virus. The company's software-driven analysis has found that the prevalence of these sequences has remained high in Indonesia; in addition, higher counts now have been found in China.

Bosutinib safe, effective for chronic myelogenous leukemia

A new drug for chronic myelogenous leukemia works for patients who have developed resistance to frontline therapy and causes fewer side effects than other medications in its class, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports at the 49th annual meeting of the American Society of Hematology.

Cancer cell line developed that is resistant to new cancer therapy

A cancer cell line that is resistant to one of the newest classes of cancer treatments has been developed by researchers who already are using it to determine what else to give patients when this happens.
