Project description:Investigation of expression differences between skin and melanomas from a transgenic BRAFV600E zebrafish model of melanoma The embryos described in this study are further analyzed in a manuscript submitted for publication by White, et al. A 15 chip study using RNA extracted from either WT zebrafish skin, mitf-BRAFV600E;p53-/- skin or mitf-BRAFV600E;p53-/- melanoma
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: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: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.
