Project description:5-aza-2'-deoxycytidine (DAC) treated and untreated Caco-2 cells were compared using an expression microarray. Total RNA from untreated Caco-2 cells was labeled with Cy3, and total RNA from DAC-treated Caco-2 cells was labeled with Cy5.
Project description:This SuperSeries is composed of the following subset Series: GSE19659: Indirect expression microarray from 5 pairs of tissues from colorectal cancer patients GSE19660: Expression microarray with 5-aza-2'-deoxycytidine-treated Caco-2 cells Refer to individual Series
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.
Project description:A neuroblastoma cell line, NB-1, was treated with mock, a DNA demethylating agent (5-aza-2'-deoxycytidine: 5-aza-dC), a synthetic retinoic acid (tamibarotene: TBT), and the combination of 5-aza-dC and TBT. A genome-wide gene expression analysis was performed using SurePrint G3 Human Gene Expression 8 x 60K v2 Microarray.
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). Five chip study. For these experiments, microarray was carried out on untreated (control) Swarm rat chondrosarcoma cells (3 biological replicates), and microarray was also carried out on Swarm rat chondrosarcoma cells treated with 5-aza-2-deoxycytidine (2 biological replicates).
