GDC-0449 inhibits the Hedgehog signaling pathway

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.

Primary cilia can suppress or promote skin cancer

Tiny, solitary spikes that stick out of nearly every cell in the body play a central role in a type of skin cancer, new research has found. The discovery in mice shows that the microscopic structures known as primary cilia can either suppress or promote this skin cancer, depending on the mutation triggering the disease.

Tiny filaments extending from cells may play a role in common malignant brain tumors

UCSF scientists have discovered that a tiny filament extending from cells, until recently regarded as a remnant of evolution, may play a role in the most common malignant brain tumor in children.

New tumor markers determine therapy intensity

Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are.

Specific features of childhood brain tumors may help guide prognosis

Specific histologic features of childhood medulloblastomas may provide insight into prognosis, according to an article in the new issue of Pediatric and Developmental Pathology.

Medulloblastoma in children - two studies find clues to treatment

Medulloblastoma is one of the most common and most malignant brain tumours among children and teenagers. These tumours grow very rapidly, and fifty percent of patients in the long term die from the condition. The details of the processes that lead to the growth of these tumours have remained unknown until now.

Finding cancer's original cell key to treatments

Cancer biologists are turning their attention to the normal cells that give rise to cancers, to learn more about how tumor growth might be stopped at the earliest opportunity.

Medulloblastoma originates in normal brain "stem" cells that turn malignant

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).

Quick formula could forecast which cancers chemo could kill

Researchers at the University of Rochester Medical Center have coined a simple formula that predicts how well a certain chemotherapy will work for targeting brain and other nervous system cancers. The formula, which publishes mid-July in Cancer Chemotherapy and Pharmacology, is pegged to two important proteins that compose such hard-to-kill tumors - one of which, ironically, makes them so drug-resistant in the first place.

Hedgehog signaling is critical for maintenance of the adult coronary vasculature

A set of promising new anticancer agents could have unforeseen risks in individuals with heart disease, suggests research at Washington University School of Medicine in St. Louis.

REST protein protects embryonic stem cells' versatility and self-renewal

A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature.

Researchers discover signaling system that halts the growth of a childhood brain cancer

A discovery by St. Jude Children's Research Hospital scientists suggests a safer way to treat medulloblastoma, a rare but often fatal childhood brain tumor.

Novel brain cancer drug HhAntag for children may damage bones

A novel drug that fully eliminated brain tumors from mice in a dramatic 2004 study has shown a darker side - causing permanent bone damage in younger mice.

New anti-cancer drug made from corn lillies kills brain tumor stem cells

A drug that shuts down a critical cell-signaling pathway in the most common and aggressive type of adult brain cancer successfully kills cancer stem cells thought to fuel tumor growth and help cancers evade drug and radiation therapy, a Johns Hopkins study shows.

Drug topotecan shows promise against Wilms tumor

St. Jude researchers have shown that the drug topotecan holds promise as a treatment for the recurrent form of a kidney cancer called Wilms tumor, a solid tumor of the kidney that arises from immature kidney cells, and the fifth most common tumor among children.

DNA repair by Brca2 prevents medulloblastoma

St. Jude investigators have gained some of the first major insights into how certain genes known to prevent cancer also guide the nervous system's normal development before birth and during infancy by repairing DNA damage.

Brca2 gene prevents medulloblastoma

Investigators at St. Jude Children's Research Hospital have gained some of the first major insights into how certain genes known to prevent cancer also guide the normal development of the nervous system before birth and during infancy by repairing DNA damage.

Glimpse into early brain development shows how nerve cells move into position

Tucked into the lower, rear portion of the brain, the cerebellum plays key roles in motor learning, motor memory and sensory perception. It's also where the majority of metastatic childhood brain tumors are located. Yet scientists still know very little about its early growth.

New radiotherapy/chemotherapy strategy improves outcomes for children with medulloblastoma

Radiotherapy that is adapted for the severity of disease and followed by a shortened course of chemotherapy substantially improves the outcome of children with a type of brain tumour called medulloblastoma, claim investigators in an Online/Article in The Lancet Oncology.

St. Jude develop strategy to speed future development of more effective and less toxic treatments for medulloblastoma

Investigators at St. Jude Children’s Research Hospital have developed a strategy to speed future development of more effective and less toxic treatments for medulloblastoma, a type of brain cancer. Medulloblastomas arise in the back of the brain and account for about 20 percent of childhood brain tumors.
