Project description:Gene expression profiling was performed on CNS tissue from neonatal mice carrying the T9H translocation and maternal or paternal duplication of proximal Chromosomes 7 and 15. Our analysis revealed the presence of two novel paternally expressed intergenic transcripts at the PWS/AS locus. The transcripts were termed Pec2 and Pec3 for paternally expressed in the CNS.Our analysis also revealed imprinting of Magel2, Mkrn3, Ndn,Ube3a and Usp29, as well as Pec2 and Pec3 in embryonic brain, 15.5 dpc, and provided a survery of biallelically expressed genes on proximal Chromosomes 7 and 15 in embryonic and neonatal CNS. This SuperSeries is composed of the following subset Series:; GSE12227: Neonatal and embyronic CNS of mice with maternal or paternal duplication of proximal chromosomes 7 and 15 (430A); GSE12230: Neonatal and embyronic CNS of mice with maternal or paternal duplication of proximal chromosomes 7 and 15 (430B) Experiment Overall Design: Refer to individual Series

Experiment Overall Design: Eight samples were analyzed by microarray analysis using GeneChip 430B (no biological replicates). RNAs were from neonatal cortex and cerebellum, and from whole brain of 13.5 and 15.5 dpc embryos, purified from mice carrying either maternal or paternal duplication of proximal chromosomes 7 and 15.

Project description:According to Mendel's laws, each parent makes an equal genetic contribution to an offspring in sexually reproducing organisms. The bipolar mitotic spindle controls the equal segregation of paternal and maternal chromosomes during the first cell division. By overexpression of a single protein, GPR-1, in the maternal strain we changed the structure of the mitotic spindle from bipolar to two monopolar spindles to segregate maternal and paternal chromosomes into different cell lineages, resulting in non-mendelian segregation for entire genomes. To follow maternal and paternal segregation of the chromosomes we used red and green histone markers respectively. By mating gpr-1-overexpressing hermaphrodites with wild-type males, mendelian F1 worms that express both markers simultaneously in all tissues and non-mendelian F1 worms that express red and green markers in different tissues will be produced representing embryos with bipolar and embryos with two monopolar spindles. Thus, we show that the rules of genetic inheritance can be changed, which may inspire the formation of a new field of synthetic zoology. Transcriptional profiling was done to investigate the differences in gene expression between mendelian and non-mendelian offspring. Approximately 60 adult worms were used per sample. Four conditions were collected: hermaphrodites of the paternal strain, hermaphrodites of the maternal strain, co-segregating (mendelian) F1 after crossing of parental strains, and (non-mendelian) F1 that segregates the paternal genotype to body wall muscle, intestine + germline and the maternal genotype to the nervous system after crossing of parental strains.

Project description:Methylation profiles of chr12-16 were generated by meDIP and array hybridisation in 3 cases with maternal uniparental disomy of chromosome 15, and three cases of paternal uniparental disomy of chromosome 15. Comparison of these profiles reveals differentially methylated (imprinted) regions on chromosome 15. Methylated DNA was enriched by immunoprecipitation using antibodies against 5-methylcytosine. meDIP and input DNA was labeled with cy5 and cy3 respectively and hybridized to Nimblegen arrays comprising 2.1 million 50-85mers covering human chromosomes 12-16 at a mean density of ~1 probe per 100bp. Resulting log2 fluorescence ratios correspond to methylation levels. Six samples were analyzed, with technical replicates for each DNA.
