7th European Breast Cancer Conference
Discovery that PARP protein exists in all breast tumors will help target chemo and predict response
The presence of a protein called PARP in tumors can help predict their response to chemotherapy, German researchers will tell the European Breast Cancer Conference on Friday, March 26. They have found that PARP expression exists across all breast cancer subtypes, and that these tumors are highly sensitive to chemotherapy. PARP positive tumors could become a new entity in breast cancer, and the researchers believe that they may be on the verge of a major change in the way breast cancer is treated.

Slowing down immune system's 'brakes' may improve HIV vaccines
Like a skittish driver slamming the brakes, a special class of T cells may be limiting the effectiveness of therapeutic vaccines for HIV by slowing the immune system response too soon, report University of Pittsburgh health science researchers in the current issue of PLoS ONE. Their study may help researchers improve the efficacy of such vaccines by devising methods to circumvent the braking mechanism of these cells.

Tumors hide out from the immune system by mimicking lymph nodes
A new mechanism explaining how tumors escape the body's natural immune surveillance has recently been discovered at EPFL in Switzerland. The study shows how tumors can create a tolerant microenviroment and avoid attack by the immune system by mimicking key features of lymph nodes. The discovery, published in Science and in Science Express, online March 25, 2010, underscores the role of the lymphatic system in cancer and may open up new possibilities for cancer treatment.

New test takes guesswork out of diagnosing early stage Alzheimer's disease
A new test developed by Japanese scientists may revolutionize how and when physicians diagnose Alzheimer's disease. According to a research report published online in the FASEB Journal, the new test measures proteins in the spinal fluid known to be one of the main causes of brain degeneration and memory impairment in Alzheimer's patients: high molecular weight A-Beta oligomers.

Nanoparticles Switch Off Cancer Genes In Human Tumors
US scientists have successfully completed a study where they showed targeted nanoparticles injected directly into a patient's bloodstream navigated into tumors, delivered double-stranded small interfering RNAs and turned off a gene that drives cancer growth. You can read about the study, by researchers from the California Institute of Technology in Pasadena (Caltech), the University of California, Los Angeles (UCLA), and others, in the 21 March advance online issue of Nature.

Taking The Guesswork Out Of Diagnosing Early-Stage Alzheimer's Disease
A new test developed by Japanese scientists may revolutionize how and when physicians diagnose Alzheimer's disease . According to a research report published online in The FASEB Journal, the new test measures proteins in the spinal fluid known to be one of the main causes of brain degeneration and memory impairment in Alzheimer's patients: high molecular weight A-Beta oligomers. This tool, once fully implemented, would allow physicians to diagnose and treat Alzheimer's disease in its early stages, a time when diagnosing the disease is very difficult. "Alzheimer's disease is a growing problem, due to aging of the population in all developed countries," said Takahiko Tokuda, M.D., Ph.D., a researcher from the Department of Neurology at the Kyoto Prefectural University of Medicine Graduate School of Medical Science in Japan who was involved in the work. "We hope that our new diagnostic test will, in the future, significantly improve the lives of people with Alzheimer's disease, and lead to much better ways of treating this devastating disorder."
