Project description:This SuperSeries is composed of the following subset Series: GSE29192: Implication of Nos2 inactivation on the transcriptome of developing cerebellum and Ptch1+/- medulloblastomas (mRNA) GSE29199: Implication of Nos2 inactivation on genomic changes in Ptch1+/- medulloblastomas (array-CGH) Refer to individual Series
Project description:The Ptch1+/- strain constitues an established mouse model for the Shh-driven type of medulloblastoma. Combined Ptch1+/- Nos2-/- mice show a two-fold increased incidence for this tumor. Here, the impact of Nos2 inactivation on copy number alterations during medulloblastoma development was investigated by array-based comparative genomic hybridization (arrayCGH) of tumor samples from both genotypes.
Project description:The Ptch1+/- strain constitues an established mouse model for the Shh-driven type of medulloblastoma. Combined Ptch1+/- Nos2-/- mice show a two-fold increased incidence for this tumor. Here, the impact of Nos2 inactivation on medulloblastoma development was investigated by gene expression profiling of tumor samples as well as healthy cerebellum at different ages and genotypes.
