Project description:Investigation of expression differences between melanomas harvested from MiniCoopR-GFP versus MiniCoopR-SETDB1 transgenic zebrafish The embryos described in this study are further analyzed in a manuscript submitted for publication by White, et al. A 12 chip study comparing gene expression levels in 80hpf animals either WT (Tu), mitf-BRAFV600E, p53-/-, or mitf-BRAFV600E;p53-/- (double)
Project description:These datasets contain the transcriptomes from E12.5 mouse retinal tissues from embryos carrying three different combinations of the Vsx2 ocular retardation J (orJ) allele and the Mitf mi (mi) allele: orJ-heterozygous, which serves as the control, orJ-homozygous, and orJ-homozygous; mi-heterozygous. The orJ allele is a recessive loss of function and the mi allele is semi-dominant. Mitf is direct target of repression by Vsx2 in the retina and is an established causal factor in the orJ ocular phenotype of microphthalmia. The goal of this analysis was to determine if blocking Mitf function in the orJ mutant would restore retinal gene expression to wild type levels. All libraries were prepared and sequenced together, facilitating direct comparisons of the gene expression profiles across the 3 genotypes.
Project description:Investigation of expression differences between melanomas harvested from MiniCoopR-GFP versus MiniCoopR-SETDB1 transgenic zebrafish. An eight-chip study using total RNA prepared from four distinct melanomas from zebrafish injected with MiniCoopR-GFP (control) transposon and four distinct melanomas from zebrafish injected with MiniCoopR-SETDB1 transposon. Injected animals carried a p53 loss-of-function mutation, a mutation in nacre, and an mitf:BRAF-V600E transgene. Each chip measures the expression level of 32,292 genes.
Project description:S23 experiment: We sought to identify the microRNAs (miRNAs) enriched in the neural crest cell (NCC) population from E11.5 mouse embryos. To accomplish this, we utilized a transgenic mouse line harboring Cre-recombinase under the control of the Wnt1 NCC-specific promoter and also carrying the R26R-YFP allele. We sorted YFP+ (NCCs) and YFP- (non-NCCs) from E11.5 Wnt1Cre-R26R mouse embryos via FACS and compared the relative enrichment of miRNAs in the YFP+ population by miRNA microarray. 220 experiment: We sought to identify the microRNAs (miRNAs) enriched in the neural crest cell (NCC) population from E10.5 mouse embryos. To accomplish this, we utilized a transgenic mouse line harboring Cre-recombinase under the control of the Wnt1 NCC-specific promoter and also carrying the R26R-YFP allele. We sorted YFP+ (NCCs) and YFP- (non-NCCs) from E10.5 Wnt1Cre-R26R mouse embryos via FACS and compared the relative enrichment of miRNAs in the YFP+ population by miRNA microarray. 221 experiment: Our research has shown that heterozygous deletion of the miRNA processing enzyme Dicer leads to developmental delay of the thymus in mouse embryos. We sought to identify the microRNAs (miRNAs) affected by the loss of a single copy of Dicer in the neural crest cell (NCC) population from E10.5 mouse embryos. To accomplish this, we utilized a transgenic mouse line harboring a floxed allele of Dicer, Cre-recombinase under the control of the Wnt1 NCC-specific promoter, and also carrying the R26R-YFP allele. We sorted YFP+ (NCCs) cells from E10.5 Dicerfl/+,Wnt1Cre,R26R and Dicer+/+,Wnt1Cre,R26R mouse embryos via FACS and compared the relative expression of miRNAs in the Dicer-heterozygotes compared to Dicer-wildtypes by miRNA microarray.
