Cancer-related gene expression profiles in NF1-associated pilocytic astrocytomas

Abstract excerpt

BACKGROUND: Individuals affected with neurofibromatosis 1 (NF1) develop juvenile pilocytic astrocytomas (JPA) at an increased frequency, suggesting that the NF1 gene product, neurofibromin, functions as a negative growth regulator for astrocytes. Previously, the authors demonstrated that NF1-associated astrocytomas exhibit deletions and loss of NF1 gene expression on the DNA and protein levels. However, little is...
