Project description:Dendrite and synapse development are critical for establishing appropriate neuronal circuits, and disrupted timing of these events can alter connectivity leading to disordered neural function. In early postnatal development of cerebellar granule neurons (CGNs), the expression of many genes is temporally regulated. Further, NFI (Nuclear Factor I) proteins have been shown to play important roles in the regulation of gene expression in developing CGNs. To identify NFI-regulated genome-wide targets involved in late maturation of mouse CGNs, we performed two groups of microarray expression analysis: (1) temporal expression arrays using 1.5 and 6 day cultures of mouse CGNs representing immature and more mature CGNs, respectively, which identified 844 Temporal-Up or Down genes; and (2) NFI-regulated genes in 6 day CGN cultures that were infected at the time of plating with lentiviral vectors expressing either NFI dominant repressor (NFI-EnR) or EnR control protein. This identified 686 NFI-Up (NFI-EnR down-regulated) or NFI-Down (NFI-EnR up-regulated) genes. Overlap analysis identified 212 temporal genes that were regulated by NFI. These results indicated that NFI plays a pivotal role in the regulation of late CGN maturation.

These results indicated that NFI plays a pivotal role in the regulation of late CGN maturation. For temporal arrays, mouse CGN progenitors were purified from P6 mouse cerebellum and cultured for either 1.5 or 6 days. Three biological replicates were analyzed for each time point. For NFI arrays, CGN progenitors from P6 mice were transduced upon plating with either NFI-EnR or EnR control lentivirus and cultured 6 days. Four pairs of biological replicates were performed.

Project description:It is generally believed that cerebellar granule neurons originate exclusively from granule neuron precursors (GNPs) in the external germinal layer (EGL). Here we identify a rare population of neuronal progenitors in the developing cerebellum that expresses Nestin. Although Nestin is widely considered a marker for multipotent stem cells, these Nestin-expressing progenitors (NEPs) are committed to the granule neuron lineage. Unlike conventional GNPs, which reside in the outer EGL and proliferate extensively, NEPs reside in the deep part of the EGL and are quiescent. Expression profiling reveals that NEPs are distinct from GNPs, and in particular, express markedly reduced levels of genes associated with DNA repair. Consistent with this, upon aberrant activation of Sonic hedgehog (Shh) signaling, NEPs exhibit more severe genomic instability and give rise to tumors more efficiently than GNPs. These studies identify a novel progenitor for cerebellar granule neurons and a novel cell of origin for medulloblastoma. 4 samples of Nestin expressing progenitors (NEPs), 4 samples of Math1 positive cells (GNPs) and 3 samples of Neural stem cells (CD133+ NSCs) were used for microarray analysis to determine the distinct genetic profile of NEPs. 4 samples of NEP-derived tumor and 4 samples of GNP-derived tumor were used to determine the similarity of those tumors by microarray analysis.
