Cancer / Oncology News From Medical News TodayLatest Cancer / Oncology News From Medical News Today.Brain Tumour Origin Identified- August 12, 2008 Australian and American scientists have identified the origins of the most malignant type of brain tumour in a discovery that could lead to better therapies and improve our understanding of how tumours initiate. The team, led by Professor Brandon Wainwright from the Institute for Molecular Bioscience at the University of Queensland in Brisbane, Australia, and Dr Robert Wechsler-Reya from Duke University in Durham, USA, studied medulloblastomas, which occur most often in children.http://www.medicalnewstoday.com/articles/117956.php Childhood Brain Tumor Traced To Normal Stem Cells Gone Bad- August 12, 2008 An aggressive childhood brain tumor known as medulloblastoma originates in normal brain "stem" cells that turn malignant when acted on by a known mutant, cancer-causing oncogene, say researchers from Dana-Farber Cancer Institute and the University of California, San Francisco (UCSF). Reporting in the Aug. 12 issue of Cancer Cell, the scientists say they have uncovered new origins for these tumors from early stem cells as well as more mature cells.http://www.medicalnewstoday.com/articles/117927.php Scientists Characterize Immune Response, Inflammatory Gene In VEEV- August 12, 2008 A collaborative team of scientists from the Uniformed Services University of the Health Sciences (USU) and the Tumor Vaccines and Biotechnology Branch, Division of Cellular and Gene Therapies, Center for Biologics Evaluation and Research, Food and Drug Administration have characterized the immune response and inflammatory gene response in Venezuelan equine encephalitis virus (VEEV). In an article published in the June 16 edition of the BMC Genomics 2008, Drs.http://www.medicalnewstoday.com/articles/117926.php Newly Discovered Molecular Switch Helps Decide Cell Type In Early Embryo Development - Finding Creates New Path To Study Birth Defects And Cancer- August 12, 2008 Researchers have discovered a central molecular switch in fruit fly embryos that opens new avenues for studying the causes of birth defects and cancer in humans. Writing about their study in the Aug. 12 Developmental Cell, scientists at Cincinnati Children's Hospital Medical Center determined the switch to be a main tuning mechanism for instructing cells whether to form sensory nerves or blood cells in different parts of the body.http://www.medicalnewstoday.com/articles/117938.php |
