Morphine blocks tumor growth
Current research suggests that taking morphine can block new blood vessel and tumor growth. The related report by Koodie et al, "Morphine suppresses tumor angiogenesis through a HIF1�/p38MAPK pathway," appears in the August 2010 issue of the American Journal of Pathology.

Molecular mechanism triggering Parkinson's disease identified in Stanford study
Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic mutation linked to Parkinson's causes the cells' death, but could also open the door to new therapeutic approaches for the malady.

One molecule, many more insulin-producing cells to treat diabetes, says Pitt team
With a single stimulatory molecule, human insulin-producing beta cell replication can be sustained for at least four weeks in a mouse model of diabetes, according to researchers at the University of Pittsburgh School of Medicine in Diabetes. They also found several cocktails of molecules that drive human beta cells to replicate, as well as important differences between mouse and human beta cells that could influence how these approaches are best used to treat diabetes.

Source - Medical News Today : Hospira Begins Phase I U.S. Clinical Trial Of Biosimilar Erythropoietin In Renal Patients Hospira, Inc. (NYSE: HSP), the world leader in generic injectable pharmaceuticals, announced the start of a U.S. Phase I clinical trial of its biosimilar erythropoietin (EPO) in patients with renal (kidney) dysfunction who have anemia , an important step on the road toward introducing a biosimilar product in the United States. Erythropoietin is a treatment for anemia associated with chronic renal failure and chemotherapy. The controlled, randomized trial of patients on hemodialysis who have already been treated with Amgen's Epogen(R) (epoetin alfa), is taking place at 20 different hemodialysis centers across the United States. Patients in the trial will be treated with both Epogen and Hospira's EPO, with each patient receiving one drug first and then being switched to the second drug. The goal of the Phase I trial is to test safety and pharmacokinetics, or measurements of the drug's blood level and distribution in the body, compared with the reference product. Pending successful completion of the Phase I trial, Hospira would launch an expanded Phase III trial in 2011, also comparing safety and efficacy of Hospira's EPO with Epogen. http://www.medicalnewstoday.com/articles/196120.php Proposed Lowering Of PSA Threshold For Biopsy Could Result In Increased Overdiagnosis And Overtreatment Of Prostate Cancer, Study New research from the US suggests that most American men diagnosed withprostate cancer receive aggressive treatment, even if their prostate-specific antigen (PSA) level is below the current recommended 4.0 nanograms per milliliter threshold for biopsy and their diagnosis indicates low-risk disease; the researchers argue against lowering the threshold, suggesting there is no evidence that waiting for PSA to reach the current threshold before doing a biopsy leads to significant increases in non-curable cases, whereas lowering it is likely to lead to overdiagnosis and overtreatment. Dr Yu-Hsuan Shao, of the Cancer Institute of New Jersey, New Brunswick, and colleagues report their findings in a paper that was published online on 26 July in the Archives of Internal Medicine, a JAMA/Archives journal. http://www.medicalnewstoday.com/articles/196014.php Canadian Researchers Testing Unique Vaccines For Prion Diseases And Common Cancers Several Canadian researchers have come together to help control the relentless spread of a prion disease, chronic wasting disease (CWD) in deer and elk, through vaccines. At the same time they aim to generate safe and effective therapies for common cancers . This simultaneous research is possible thanks to a unique connection they have discovered between the two unrelated diseases. The project builds on links between prion proteins present in certain prion diseases like CWD in animals and common cancers in people like melanoma and lymphoma . The multi-provincial research is made possible by Vancouver-based PrioNet Canada's Bootstrap program and involves three scientists along with two industry partners, Toronto-based Amorfix Life Sciences Ltd. and Saskatoon-based PREVENT - the Pan Provincial Vaccine Initiative. http://www.medicalnewstoday.com/articles/195975.php Starve A Cancer Researchers at Boston College, MA, have found that reducing calorie intake can restrict the growth and spread of brain cancer .
