Project description:Transcriptome analysis of urothelial KRT5-traced and KRT8-traced YFP-sorted cells with and without combinatorial loss of Trp53 and Pten. Bladders from 2-month-old KRT5-CreERT2, Rosa26YFP/LacZ mice, 2-month-old KRT8-CreERT2, Rosa26YFP/LacZ mice, 5-month-old KRT5-CreERT2, p53flox/flox, Ptenflox/flox, Rosa26YFP/+ mice, and 5-month-old KRT8-CreERT2, p53flox/flox, Ptenflox/flox, Rosa26YFP/+ mice were enzymatically dissociated, sorted for YFP by FACS, harvested, resuspended in Trizol and snap frozen for subsequent molecular analysis.
Project description:Describing the chromatin landscape of normal urothelial cells by ChIPseq analysis of 6 histones marks and 1 chromatin factor in 2 patient derived Normal Human Urothelial cells
Project description:This SuperSeries is composed of the following subset Series: GSE31864: Epigenome profiling of repressive histone modifications, DNA methylation and gene expression in normal and malignant urothelial cells GSE31865: Global methylation in normal and malignant urothelial cells Refer to individual Series
Project description:Genome wide DNA methylation profiling of normal and upper-tract urothelial carcinomas tissues. The Illumina Infinium EPIC arrays was used to obtain DNA methylation profiles across approximately 866,091 probes. Samples included 35 upper-tract urothelial carcinomas samples and 8 adjacent normal tissues
Project description:We have created 5-methylcytosine profiles for normal and malignant urothelial cells. Competitive hybridization of background and 5-methylcytosine enriched immunoprecipiated DNA fractions
Project description:Activating mutations of FGFR3 are found in a high proportion of bladder tumours. The molecular consequences of FGFR3 mutation in urothelial cells and the mechanisms by which mutant FGFR3 may drive bladder tumourigenesis are largely unknown. We used expression arrays to identify downstream targets of mutant FGFR3 signalling in normal urothelial cells. TERT-immortalized normal urothelial cells stably transduced to express the most common FGFR3 mutation (S249C) were compared with control cells transduced with the empty vector (pFB).
Project description:To gain a more depth knowledge of repressive epigenetic gene regulation in UCC, we have profiled H3K9m3 and H3K27m3 in normal and malignant urothelial cells. We matched these profiles to those 5-methylcytosine and gene expression. We hypothesized that differences represent pro-carcinogenic events within the urothelium. We identified a panel of genes with cancer specific epigenetic mediated aberrant expression. Two repressive histone modifications (H3K9m3 and H3K27m3) , cytosine methylation and gene expression were compared between normal human urothelial cell line (NHU) and malignant urothelial cells (EJ and RT112).
