...ge include prostate cancer, nervous system cancer, neurofibromatosis (fleshy growths of abnormal nerve tissue), the most common type of dwarfism, Apert syndrome (malformation of the skulls, hands and feet), and Marfan syndrome, which involves defects of the eyes, bones, heart and blood vessels. The schizophrenia stu...

Gene that prevents tumor growth also carries messages from circadian clock

...ts by physicians that many patients suffering from neurofibromatosis also suffer from sleep disturbances. But this is the first time someone has definitively linked Nf1 to the circadian system, said Julie Williams, PhD, first author of the study by scientists at the University of Pennsylvania School of Medicine. Their...

Tiny molecular change inactivates tumor suppressor gene in neurofibromatosis

Researchers identify potential treatment for learning disability in neurofibromatosis

...ers studying learning disabilities associated with neurofibromatosis type 1, or NF1, have traced the problem to excessive activity of a crucial signaling molecule and have successfully reversed the disabilities in mice by giving them an experimental drug. The findings provide hope that these learning problems may one...

Making meningiomas: Scientists pioneer animal model of human meningioma

...an be associated with a hereditary disorder called neurofibromatosis type 2. Neurofibromatosis type 2 (NF2) is caused by mutations in the NF2 gene, a tumor suppressor gene whose disruption facilitates the development of cancer. However, both sporadic and familial cases of meningioma development are often associated wi...

Researchers identify cell, genetic environment behind nerve-tissue tumors that lead to cancer

The magic behind merlin

...is encoded by the NF2 gene. Mutations in NF2 cause neurofibromatosis type 2, a hereditary cancer syndrome characterized by a predisposition to develop tumors of the central nervous system. Although NF2 was cloned a decade ago, this paper by Dr. McClatchey and colleagues provides unprecedented insight into the biologic...

Researchers identify important function of NF2 tumor suppressor

... known to be involved in the rare genetic disorder neurofibromatosis type 2 (NF2). The protein, called merlin, plays a key role in cell-to-cell communication and may be involved in other types of cancer. The discovery also may support the theory that some tumors are destined to spread or metastasize from the outset,...

Ancient DNA analysis unveils mystery of history's most horribly deformed man -- The Elephant Man

Based on published clinical features, cancer geneticists and other clinical geneticists believe that Merrick had at least ...

Brain tumor growth requires abnormal neighbors

... St. Louis. In trying to develop a mouse model of neurofibromatosis 1 (NF1), a genetic disorder that predisposes children to certain types of brain tumors, the team discovered that tumors only developed when all brain cells were genetically abnormal, not just the cell type that becomes cancerous. The study is feature...
