Project description:Genome-wide DNA methylation profiling of SETD2-null 786-0 RCC cells treated with decitabine (100nM and 300nM) or DMSO vehicle. The Illumina Infinium HumanMethylation EPIC BeadChip was used to obtain DNA methylation profiles across approximately 850K CpGs.

Project description:While early stages of clear cell renal cell carcinoma (ccRCC) are curable, survival outcome for metastatic ccRCC remains poor. The purpose of the current study was to apply a new individualized bioinformatics analysis (IBA) strategy to these transcriptome data in conjunction with Gene Set Enrichment Analysis of the Connectivity Map (C-MAP) database to identify and reposition FDA-approved drugs for anti-cancer therapy. We demonstrated that one of the drugs predicted to revert the RCC gene signature towards normal kidney, pentamidine, is effective against RCC cells in culture and in a RCC xenograft model. Most importantly, pentamidine slows tumor growth in the 786-O human ccRCC xenograft mouse model. To determine which genes are regulated by pentamidine in a human RCC cell line, 786-O, we treated these cells with pentamidine and performed transcriptional profiling analysis. We used microarrays to determine the set of genes regulated by pentamidine in 786-O renal cell cancer cells. Total RNA was isolated from 786-O cells treated with 25 μM pentamidine or vehicle control (DMSO) for 6 hours and hybridized to Affymetrix microarrays.

Project description:786-0 is a cell line derived from a clear cell renal carcinoma. Previous studies have shown that the 786-O cell line harbors an inactivating mutation in the von-Hippel Lindau (VHL) gene. Mutations in the VHL gene occur in the majority of sporadic clear cell renal cell. To determine how inactivation of the VHL affects cellular functions, we created a derivative of 786-0, which we call 786-VHL in which a functional allele of VHL has been introduced back into the 786-O cell line. The renal cell carcinoma cell line 786-0, which harbors a mutated allele of VHL, was compared to a cell line derived from 786-0, termed 786-VHL, that contains a functional allele of VHL. Genes whose expression characteristics were dependent on functional VHL were identified.

Project description:Genome-wide DNA methylation profiling of primary AML samples treated with 100nM decitabine (DAC), cytarabine (AraC), or DMSO. Eight distinct AML samples were grown using an in vitro stromal co-culture system for 4 days and then treated with either DAC, Ara-C or DMSO for 3 days. DNA was prepared for genome-wide methylation analysis with the Illumina Infinium 450k Human DNA methylation BeadChip. DNA from each sample/treatment was analyzed on duplicate arrays.

Project description:Kidney cancer accounts for more than 100,000 deaths per year world-wide. More than 80% are clear cell tumors (ccRCCs) and the majority are associated with loss of function of the von Hippel Lindau (pVHL) tumor suppressor resulting in upregulation of HIF-{alpha} subunits, and activation of HIF-dependent transcriptional pathways. Recent GWAS studies have discovered RCC-susceptibility loci both within EPAS1 (HIF-2{alpha}) and in an intergenic region of unknown function on 11q13.3. As part of an ongoing study to define the direct transcriptional targets of HIF-2 in renal cancer, we undertook a genome-wide analysis of HIF-2-binding sites in pVHL-defective 786-O cells (that lack functional HIF-1{alpha} due to a truncated transcript) using chromatin immunoprecipitation with antibodies directed against HIF-2{alpha} and its dimerization partner HIF-1{beta}, coupled to high-throughput sequencing (ChIP-seq). Amongst approximately 600 pangenomic HIF-2{beta} ChIP signals, we observed strong binding (ranked 12th by peak height) almost precisely coinciding with the RCC predisposition SNP rs7105934 on 11q13.3. We report binding of HIF-2{alpha} and HIF-1{beta} in 786-O clear cell renal carcinoma cells. 3 samples examined, HIF-2{alpha}, HIF-1{beta} and pre-immune control ChIP.
