Brain tumors represent the most common solid tumor of childhood, with gliomas comprising the largest fraction of these cancers. Several features distinguish them from their adult counterparts, including their natural history, causative genetic mutations, and brain locations. These unique properties suggest that the cellular and molecular etiologies that underlie their development and maintenance might...
Low‐grade brain tumors (pilocytic astrocytomas) that result from a genomic rearrangement in which the BRAF kinase domain is fused to the amino terminal of the KIAA1549 gene (KIAA1549:BRAF fusion; f‐BRAF) commonly arise in the cerebellum of young children. To model this temporal and spatial specificity in mice, we generated conditional KIAA1549:BRAF strains that coexpresses green fluorescent protein...
Pilocytic astrocytoma (PA) is the most common pediatric brain tumor. Most arise in the cerebellum, but they also can develop in the brainstem and optic nerve, where gross total resection (GTR) is not possible. In the absence of GTR, significant variability in both clinical behavior and histology exists. To identify potential markers associated with poor clinical outcome, we retrospectively assessed...
