Normal Growth Control and Tumor Formation in the Mammalian Brain
Overview
The development of the mammalian brain is a highly regulated process involving both cell-autonomous and non-cell-autonomous decisions that determine cell fate, proliferation, migration and death. The genes that govern these critical decisions are often mutated in human cancers, and their de-regulated function in the central nervous system (CNS) leads to the development of brain tumors. Our laboratory is interested in understanding the key signals that control normal neural stem cell (NSC) and glial cell growth and differentiation in vitro and in vivo. To this end, we study the genes mutated in the two cancer predisposition syndromes, neurofibromatosis 1 (NF1) and neurofibromatosis 2 (NF2), in which affected individuals develop brain tumors. We have generated numerous genetically-engineered mouse models to explore the relationship between developmental neurobiology (normal growth regulation in the brain) and neuro-oncology (brain tumor formation).
