The laboratory of Dr. Fr©d©ric Charron, in Montreal, made this discovery The laboratory of Dr. Fr©d©ric Charron, a researcher at the Institut de recherches cliniques de Montr©al (IRCM), has discovered a new molecular mechanism that permits the guidance of visual nerves towards the brain. Their findings have been published in the current issue of the Journal of Neuroscience. The research was conducted in collaboration with Dr. Tomomi Shimogori from the RIKEN Brain...

 Genetic variations in the Sonic Hedgehog pathway increase the likelihood of recurrence, reduce survival time and limit response to therapy for people with non-muscle invasive bladder cancer, scientists from The University of Texas M. D. Anderson Cancer Center reported today at the American Association for Cancer Research Frontiers in Cancer Prevention Research Conference. "These variations are strongly associated with response to standard immunotherapy that patients receive after tumor...

The master gene Math1 is involved in the genesis of the most common childhood brain tumor, medulloblastoma, said researchers from Baylor College of Medicine (www.bcm.edu) in a report in the current issue of the journal Science. The finding provides a new treatment target in the deadly disease that most commonly affects children and young adults, said Dr. Huda Zoghbi (http://www.bcm.edu/pediatrics/index.cfm?Realm=99992437&This_Template=huda_zoghbi,...

Howard Hughes Medical Institute (HHMI) researchers have identified a new factor that is necessary for the development of many forms of medulloblastoma, the most common type of malignant childhood brain cancer. HHMI investigator Huda Y. Zoghbi and colleagues at Baylor College of Medicine prevented medulloblastoma from developing in mice by shutting down production of the protein Atoh1 in susceptible brain cells. The team's findings, reported in the December 4, 2009, issue of Science, suggest...

Researchers at the University of Wisconsin-Madison School of Medicine and Public Health have identified a molecular mechanism that allows two powerful signaling pathways to interact and begin a process leading to colorectal tumors. "We are very excited about these findings," says Vladimir Spiegelman, an associate professor of dermatology. "Drugs could be developed to block this mechanism and prevent colorectal cancer, which affects millions of people worldwide." The research will appear in...

Researchers at the California Institute of Technology (Caltech) have proposed a novel model that differs from a widely held hypothesis about the mechanisms by which developing animals pattern their tissues and structures. Cells in a developing animal require information about their position with respect to other cells so that they can adopt specific patterns of gene expression and function correctly. The most accepted paradigm is that this positional information comes in the form of chemical...

Study data appears in New England Journal of Medicine Analyses of clinical trial results published today in the New England Journal of Medicine (NEJM) shows a potential new investigational therapy for advanced and metastatic basal cell skin cancer. The study, conducted at TGen Clinical Research Service (TCRS) at Scottsdale Healthcare and two other sites appears to demonstrate tumor shrinkage and limited side effects. TCRS is a strategic alliance between the Translational Genomics Research...

The Hedgehog signaling pathway is involved in a preliminary study and case report describing positive responses to an experimental anticancer drug in a majority of people with advanced or metastatic basal cell skin cancers. One patient with the most common type of pediatric brain cancer, medulloblastoma, also showed tumor shrinkage. Initial results of the drug trial, conducted at Johns Hopkins (Baltimore), the Karmanos Cancer Center (Detroit) and the Translational Genomics Research Institute...

Hedgehog trial results suggest antitumor activity in basal cell skin cancer SCOTTSDALE, Ariz., Sept. 2 /PRNewswire-USNewswire/ -- A study published today in the New England Journal of Medicine reports a potential new investigational therapy for advanced and metastatic basal cell skin cancer tested at the Virginia G. Piper Cancer Center at Scottsdale Healthcare and other sites appears to demonstrate tumor shrinkage and limited side effects in patients. "Inhibition of the Hedgehog Pathway...

Scientists in Switzerland have discovered a way to block the growth of human colon cancer cells, preventing the disease from reaching advanced stages and developing liver metastases. The research shows that blocking the so-called Hedgehog-GLI pathway can prevent the growth of tumors, metastatic lesions and cancer stem cells, the cells thought to lie at the root of cancer growth. Colon cancer often begins in a treatable form when it is confined to the bowel wall, but later it can develop to an...
