Hedgehog pathway activation is required for proliferation of cerebellar granule cell neuron precursors during development and is etiologic in certain cerebellar tumors. To identify genes expressed specifically in granule cell neuron precursors, we used oligonucleotide microarrays to analyze regulation of 13,179 genes/expressed sequence tags in heterogeneous primary cultures of neonatal mouse cerebellum that respond to the mitogen Sonic hedgehog. In conjunction, we applied experiment-specific noi ...[more]

Transcription profiling of mouse P5 cerebellum to investigate conserved mechanisms across development and tumorigenesis revealed by a mouse development perspective of neuroblastoma

Project description:Identification of common mechanisms underlying organ development and primary tumor formation should yield new insights into tumor biology and facilitate the generation of relevant cancer models. We have developed a novel method to project the gene expression profiles of medulloblastomas (MBs)—human cerebellar tumors—onto a mouse cerebellar development sequence: postnatal days 1-60 (P1-P60). Genomically, human medulloblastomas were closest to mouse P1-P10 cerebella, and normal human cerebella were closest to mouse P30-P60 cerebella. Furthermore, metastatic MBs were highly associated with mouse P5 cerebella, suggesting that a clinically distinct subset of tumors is identifiable by molecular similarity to a precise developmental stage. Genewise, down- and up-regulated MB genes segregate to late and early stages of development, respectively. Comparable results for human lung cancer vis-a-vis the developing mouse lung suggest the generalizability of this multiscalar developmental perspective on tumor biology. Our findings indicate both a recapitulation of tissue-specific developmental programs in diverse solid tumors and the utility of tumor characterization on the developmental time axis for identifying novel aspects of clinical and biological behavior. Experiment Overall Design: Time series with technical (split aliquots) replicates.

Effect of chronic glucocorticoid (GC) treatment on neonatal mouse whole cerebellum and whole lung

Project description:Dexamethasone (1ug/g, Dex) or vehicle (saline) injected into postnatal days 0-7 (P0 to P7) of C57BL6J mouse pups every day. Whole organ were harvested at P7. Biological replicates (n = 4) per condition: whole cerebellum or whole lung, treated with dexamethasone or vehicle. This microarray experiment was performed concurrently with the study described in PMID:19164857. The culture and experiment designs in PMID:19164857 are identical to those in this microarray experiment. KEYWORDS: cell type comparison, treatment comparison.

Differential gene expression in stellate sympathetic ganglia after cardiac pressure overload

Project description:Transcriptom analysis of stellate sympathetic ganglia after 8 weeks of cardiac pressure overload caused by transverse aortic constriction. Comparative transcriptome analysis was determined using the GeneChip Mouse Genome 430 2.0 Array (Affymetrix, Santa Clara, CA, USA). Six microarrays from stellate sympathetic ganglia of mice were performed 8 weeks after transverse aortic constriction or sham operation.

Expression data of Myh6-MeCP2 transgenic mice

Project description:Hearts of Myh6-MeCP2 transgenic mice and wildtype littermates were rapidly dissected and flash frozen. We used Affymetrix microarrays to assess gene expression changes induced by overexpression of MeCP2 under the control of a cardiomycyte specific promoter. Hearts were dissected 2-3 weeks after birth from transgenic Myh6-MeCP2 mice and littermates to study gene expression alterations.

Target genes of thyroid hormone in cerebellum neurons

Project description:Cerebellar post-natal development is particularly sensitive to thyroid hormone and low levels of thyroid hormone (hypothyroidism) result in permanent defects in cerebellar architecture and function. All cell types of the cerebellum are affected, but the main sign of hypothyroidism in mice is the persistence of the external granular layer, composed of mitotic neuronal precursors at P21. To make the genetic link between thyroid hormone and cerebellar development, we sought to identify new thyroid hormone target genes, in particular in granule cells which represent the vast majority of cerebellar cells. Primary cultures of cerebellar neurons were made by dissociation of cerebella from newborn wild-type mice. These cells were plated 48 hours in serum-free medium to avoid invasion of the culture by glial cells. In order to include a kinetic and a maximum number of target genes, several cultures were either treated or left untreated as controls for 6 hours (T1), 16 hours (T2), 24 hours (T3) or 48 hours (T4) and results were pairwise compared for each time point.

Transcriptome analysis of arabinose fermentation by engineered Saccharomyces cerevisiae

Project description:Saccharomyces cerevisiae IMS0002 which, after metabolic and evolutionary engineering, ferments the pentose sugar arabinose. Glucose and arabinose-limited anaerobic chemostat cultures of IMS0002 and its non-evolved ancestor IMS0001 were subjected to transcriptome analysis to identify key genetic changes contributing to efficient arabinose utilization by strain IMS0002. Glucose- and arabinose limited anaerobic chemostat cultivation of strains IMS0002 and glucose limited IMS0001 at D= 0.03 h-1

Gene expression of cerebellar granule cell layer

Project description:We performed gene-expression analysis of mouse cerebellar granule cell layer as compared to that of Purkinje cells. DNA microarray analysis detected genes in cerebellar granule cell layer, most of which are classified into functional molecule categories. Our comparative analysis between Purkinje cells and the granule cell layer showed that the characteristic expression pattern in Purkinje cells was particularly represented by M-bM-^@M-^\the neural communication systemM-bM-^@M-^] components. Pukinje cells and granule cell layer of the mouse cerebellum were collected by laser microdissection for RNA extraction and hybridization on Affymetrix microarrays.

CLN3 patients with differing progression of the disease

Project description:Mutations in the CLN3 gene lead to juvenile neuronal ceroid lipofuscinosis, a pediatric neurodegenerative disorder characterized by visual loss, epilepsy and psychomotor deterioration. Although most CLN3 patients carry the same 1 kb deletion in the CLN3 gene, their disease phenotype can be variable. The aims of this study were (1) to identify genes that are dysregulated in CLN3 disease regardless of the clinical course that could be useful as biomarkers, and (2) to find modifier genes that affect the progression rate of the disease. Genome-wide expression profiling was performed in 8 CLN3 patients, homozygous for the 1 kb deletion, with different disease progression and compared to seven age and gender matched controls. Lymphocytes from eight patients diagnosed with CLN3 disease,all homozygous for the 1 kb deletion in the CLN3 gene and classified as having rapid (n = 2), average (n=4), and slow disease progression (n = 2), were used. These eight patients did not receive anticonvulsive medication. In addition, lymphocytes of seven age and gender matched controls were included in the study. Lymphocytes were prepared from fresh patient blood samples by Ficoll-gradient centrifugation (BiocollM-BM-., Biochrom AG, Berlin, Germany) according to the manufacturerM-bM-^@M-^Ys protocol and used for RNA isolation (RNeasyM-BM-. Micro Kit, Qiagen, Hilden, Germany).
