The developing neocortex contains two types of progenitor cells for glutamatergic, pyramidal-projection neurons. The first type, radial glia, produce neurons and glia, divide at the ventricular surface, and express Pax6, a homeodomain transcription factor. The second type, intermediate progenitor cells, are derived from radial glia, produce only neurons,(More)
The deep cerebellar nuclei (DCN) are the main output centers of the cerebellum, but little is known about their development. Using transcription factors as cell type-specific markers, we found that DCN neurons in mice are produced in the rhombic lip and migrate rostrally in a subpial stream to the nuclear transitory zone (NTZ). The rhombic lip-derived cells(More)
Selenoprotein K (SelK) is a membrane protein residing in the endoplasmic reticulum. The function of SelK is mostly unknown; however, it has been shown to participate in anti-oxidant defense, calcium regulation and in the endoplasmic reticulum associated protein degradation (ERAD) pathway. In order to study the function of SelK and the role of selenocysteine(More)
Dysregulated Hedgehog (Hh) signaling has been implicated in a growing number of human cancers. Although first identified as an important developmental signaling pathway crucial for cellular proliferation, differentiation, and migration during organogenesis in invertebrates, these fundamental processes have been co-opted in human cancers. Initial evidence(More)
Mouse models have increased our understanding of the pathogenesis of medulloblastoma (MB), the most common malignant pediatric brain tumor that often forms in the cerebellum. A major goal of ongoing research is to better understand the early stages of tumorigenesis and to establish the genetic and environmental changes that underlie MB initiation and(More)
