Signaling pathway discovered which may help find treatment for glioblastoma multiforme
Malignant gliomas are the most common subtype of primary brain tumor – and one of the deadliest. An international team of scientists, headed by researchers at the Ludwig Institute for Cancer Research (LICR) at the University of California, San Diego School of Medicine, report that they have discovered a new signaling pathway between GBM cells – one that, if ultimately blocked or disrupted, could significantly slow or reduce tumor growth and malignancy.

'Gateway' gene discovered for brain cancer
Researchers have discovered that the same genetic regulator that triggers growth of stem cells during brain development also plays a central role in the development of the lethal brain cancer malignant glioma. In experiments on mice with such gliomas, they showed that knocking out the function of a particular regulatory protein, Olig2, almost completely eliminated tumor formation.

Regulatory Approval for New Cotara(R) Brain Cancer Clinical Trial
Peregrine Pharmaceuticals, Inc. (Nasdaq: PPHM), a biopharmaceutical company with a portfolio of innovative, clinical stage products for the treatment of cancer and hepatitis C virus infection, today announced that it has received regulatory approval in India for a new clinical trial of its lead tumor necrosis therapy (TNT) agent Cotara(R). The trial is designed to test the safety and efficacy of Cotara in patients with glioblastoma multiforme, a deadly form of brain cancer. Cotara is currently being studied in a multi-center U.S. glioblastoma trial. Previous studies using Cotara to treat brain cancer have produced encouraging results, and Peregrine expects that positive data from this trial in combination with data from the ongoing U.S. clinical trial should provide the foundation for planning the future development and commercialization of Cotara.

Chromosomal Testing Can Determine Brain Tumor Therapy
A trial involving two types of rare, malignant but treatable brain tumors shows that missing portions of two chromosomes can predict which patients will likely do better with therapy. The results, says senior author Walter J. Curran Jr., M.D., professor and chair of radiation oncology at Jefferson Medical College of Thomas Jefferson University in Philadelphia, represents a paradigm shift in treating such tumors, known as gliomas.

New mouse model that closely mimics human medulloblastoma
Researchers have created a mouse model that closely mimics human medulloblastoma, the most common type of childhood brain tumor. The new model, which was created by knocking out a key component of the DNA repair machinery, will aid in exploring the genetic roots of this deadly brain cancer. The researchers, led by Howard Hughes Medical Institute investigator Frederick W. Alt, published their findings the week of April 24, 2006, in the early online edition of the Proceedings of the National Academy of Sciences. Catherine Yan, who is in Alt's laboratory at Children's Hospital Boston, was lead author of the article. Other co-authors were from Brigham & Women's Hospital, CBR Institute of Biomedical Research, Children's Hospital and Dana-Farber Cancer Institute, all of Harvard Medical School.

Discovery could change the way doctors treat glioblastomas
Researchers at UCLA's Jonsson Cancer have identified key characteristics in certain deadly brain tumors that make them 51 times more likely to respond to a specific class of drugs than tumors in which the molecular signature is absent. The discovery of the telltale molecular signature the expression of a mutant protein and the presence of a tumor suppressor protein called PTEN will allow researchers to identify patients who are likely to respond to the drug treatment before they undergo therapies that are not likely to work, said Dr. Paul Mischel, a UCLA associate professor of pathology and laboratory medicine and a Jonsson Cancer Center researcher.

Glioblastoma Gene Variations Can Predict Treatment Response
Screening glioblastoma brain tumors for two gene variations can reliably predict which tumors will respond to a specific class of drugs, a new study shows. The findings may lead to improved treatment for this devastating disease. The study was funded in part by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH), and appears in the November 10, 2005, issue of the New England Journal of Medicine. Glioblastomas are the most common malignant brain tumors in adults, and they are notoriously difficult to treat successfully. "The survival with glioblastoma is usually a year on average, and that hasn't improved in a while, so this is a very serious and challenging disease," says Paul Mischel, M.D., of the David Geffen School of Medicine and Jonsson Comprehensive Cancer Center at the University of California , Los Angeles (UCLA), who led the study. While drugs are available to help treat glioblastoma, they often have minimal effect, and doctors usually have time to try only one or two treatments before the disease causes severe impairment. Glioblastomas feature many genetic variations that affect their response to different treatments. Researchers are trying to identify these genetic factors and to tease apart how they affect the disease in order to determine which patients are the most likely to benefit from specific drugs.

The panel has developed evidence-based reviews that consolidate the information available and identify questions to be answered in future research. The two new reviews are published in the September 1, 2005 issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO.

Combined gene therapy can eliminate glioblastoma multiforme
Despite aggressive treatment, glioblastoma multiforme (GBM) the most common and deadly of brain cancers usually claims the lives of its victims within six to 12 months of diagnosis. Because GBM is so aggressive, the disease has been the target of a number of laboratory and clinical studies investigating the effectiveness of gene therapy to deliver novel therapies to the brain. In laboratory studies, this type of gene therapy has proved almost completely effective. But in clinical trials, it has had limited effectiveness.

Errant neuro-developmental gene implicated in brain cancer
A gene that's normally silenced after contributing to brain development was found to be expressed in cells from medulloblastoma, the most common form of pediatric brain malignancy in children, scientists report in an article published in the February 1 issue of the journal Cancer Research. In their study, the scientists discovered that multiple extra copies of the gene, called OTX2, had been switched back on among tumor cells removed from patients with medulloblastoma brain tumors. In the United States, medulloblastoma accounts for approximately 30 percent of all pediatric brain tumors.
