Genes modulated by DNA demethylation in UM1 cells

ABSTRACT: Ornithine decarboxylase antizyme 1 mediates DNA demethylation. Using a human oral cancer cell line, UM1, genes induiced by DNA demethylation were screened. To verify the methylation status of those induced genes, the gene expression profile was compared with that of 5-Aza-2’-deoxycytidine treated sample. Keywords: DNA demthylation, ornithine decarboxylase antizyme 1, 5-Aza-2’-deoxycytidine

Genes modulated by DNA demethylation in UM1 cells

Project description:Ornithine decarboxylase antizyme 1 mediates DNA demethylation. Using a human oral cancer cell line, UM1, genes induiced by DNA demethylation were screened. To verify the methylation status of those induced genes, the gene expression profile was compared with that of 5-Aza-2â-deoxycytidine treated sample. Preparation of samples, hybridization process and data analysis were performed according to the manufacture's protocol (BD Biosciences). To verify the genes induced by ornithine decarboxylase antizyme via DNA demethylation, 5-Aza-2â-deoxycytidine treatment was carried out as a parallel experiment.

MCF7 cells gene expression change by inducing CpG demethylation using 5-Aza-2'-deoxycytidine (Aza)

MCF7 cells gene expression change by inducing CpG demethylation using 5-Aza-2'-deoxycytidine (Aza)

Project description:Promoter methylation is able to induce downregulation of gene expression. 5-Aza-2'-deoxycytidine(Aza), methytransferase inhibitor, induce CpG demethylation. Here, 5-Aza-2'-deoxycytidine(Aza) is treated in a human breast cancer cell, MCF7, for detection of gene expression change. To analyze gene expression change by aza, control RNA isolated from MCF-7 was compared with RNA isolated from MCF-7 treated with 5uM and 10uM aza.

Improved DNA methylation analysis via enrichment of demethylated cells expressing an X-inactivated GFP transgene

Project description:The demethylating drug 5-aza-2’-deoxycytidine (5-aza-2dC) is frequently used to investigate the effect of global DNA demethylation on gene expression in cultured mammalian cells. Here, we utilize a novel method that uses the reactivation of an X-inactivated GFP transgene as a marker to enrich for cells that have undergone drug-induced demethylation. By combining it with microarray gene expression profiling, we demonstrate the method’s utility in identifying genes activated by global DNA demethylation. Keywords: 5-aza-2'-deoxycytidine; methylation; dermal fibroblast; X-linked GFP

Genome-wide DNA demethylation of TGW (neuroblastoma cell line) after treatment of mock and 5-aza-2'-deoxycytidine (5-aza-dC)

Project description:A neuroblasoma cell line, TGW, was treated with a DNA demethylating agents (5-aza-2'-deoxycytidine: 5-aza-dC). Genome-wide DNA methylation was analyzed using the Infinium Human MethylationEPIC BeadChip.

Analysis of normal lung cells treated with 5-aza-dC to induce DNA demethylation

Project description:Analysis of 2 cultured normal lung cell lines, Normal Human Bronchial Epithelial (NHBE) and Human Small Airway Epithelial (SAEC) cells (Lonza, Walkersville, MD), following treatment with 5-aza-dC to induce DNA demethylation. These results provide insight into the role of epigenetic alterations, specifically demethylation, in differential gene expression in various lung neoplasms. Two normal lung cell lines, NHBE and SAEC, were treated with 5uM 5-aza deoxycytidine for 72 hours and Trichostatin A for 24 hours prior to harvesting total RNA for expression array analysis using the Affymetrix Human Genome U133 Plus 2.0 expression platform. Signal intensity and statistical significance was established for each transcript using dChip version 2005. Two-fold increase based on the 90% confidence interval of the result and expression minus baseline >50 was used as the statistical cutoff value after 5Aza-dC and/or TSA treatment to identify upregulated candidate genes.

5-aza-2-deoxycytidine treatment of Swarm rat chondrosarcoma cells

Project description:The puropose of this experiment was to identify gene expression changes that result from 5-aza-2-deoxycytidine induced DNA demethylation of Swarm rat chondrosarcoma cells. The gene expression profiles of untreated Swarm rat chondrosarcoma cells were compared to the gene expression profiles of Swarm rat chondrosarcoma cells that were treated for 5 passages with a low dose of 5-aza-2-deoxycytidine (0.1uM).

MicroRNA expression data from human breast cancer cell lines after demethylation treatment.

Project description:The contribution of aberrant DNA methylation and the downstream effects in tumorogenesis through silencing of tumor suppressor genes (TSGs) and microRNAs has been investigated. Since these epigenetic alterations can be reversed, we investigated the effects of the epigenetic therapy in breast cancer cell lines. We used microarrays to investigate the global microRNA expression profile after demethylation treatment with 5-aza-2’-deoxycytidine (DAC) in breast cancer cell lines and identified distinct classes of early and late systematic stable or transient effects of the treatment.
