EZH2 Overexpression in Breast Cancer is due to MicroRNA-Dependent Suppression of ZBTB4

Project description:In order to Sp1 and EZH2-specific gene expression pattern in breast cancer, small interfering RNA for Sp1 and EZH2 was transfected in MDA-MB-231 cells. Four groups of samples are included: 1. si control (siCT_1, siCT_2, siCT_3). 2. siSp1 (siSp1_1, sisSp1_2, siSp1_3). 3. si control (siCT_A, siCT_B, siCT_C). 4. siEZH2 (siZEH2_1, siZEH2_2,siEZJ2_3). Gene expression profiles of Sp1 and EZH2 depleted cells were compared to that of siRNA controls. Experiments were performed in MDA-MB-231 cells.

Genome wide map of EZH2 and SOX2 binding in mammospheres reveals common set of bound regions.

Project description:We generated genome wide map of EZH2 and SOX2 protein binding in MDA-MB-231 mammospheres and we discovered enrichment of both protein on the genes regulated by SCIRT

Chip-chip from MDA-MB-231 cells with SMYD2 and EZH2

Project description:The histone methyl transferase EZH2 and SMYD2 are master epigenetic regulators involved in histone methylation and gene transcription repression. Here, we report that SMYD2 and EZH2 may act as a complex in transcriptional regulation and are involved in the progression of breast cancer. ChIP-on-chip assays were performed to find unique promoters co-targeted by EZH2 and SMYD2 in MDA-MB-231 cells.

miRNAs were significantly regulated by myocardin and ERα

Project description:Using microarray, we compared miRNAs expression profiles of MDA-MB-231 cells transfected with myocardin and empty vector (pcDNA3.1) and found that 25 miRNAs were significantly changed in myocardin-transfected groups (17 up-regulated and 9 down-regulated miRNAs). Moreover, we showed that 18 of 25 miRNAs significantly regulated by myocardin were inhibited by ERα in MDA-MB-231 cells. In addition,through a microarray approach, we identify the subset of miRNAs modulated by ERα in MDA-MB-231 cells. Our results determined that ERα may function as tumor-promoter through down-regulating expression of 3 miRNAs (miR-26b, miR-146a and miR-331-3p) in MDA-MB-231 cells.

Gene expression data of cancer cell lines treated with inhibitors of G9a and EZH2

Project description:Epigenetic modifications modulate gene expression and, when deregulated, contribute to the development and progression of cancer. G9a (EHMT2) and EZH2 are two histone methyltransferases commonly upregulated in several cancer types, leading to the silencing of tumor suppressor genes. We performed high throughput sequencing of a breast cancer cell line (MDA-MB-231), an ovarian cancer cell line (CAOV3) and a melanoma cell line (D14) treated with a G9a inhibitor (UNC0642), EZH2 inhibitor (GSK126) and their combination.

Genes regulated by HS3ST2

Project description:We used Affymetrix HG U133 Plus 2.0 GeneChips to compare the transcriptome of HS3ST2-transfected and control vector-transfected MDA-MB-231 cells. MDA-MB-231 cells were transfected with HS3ST2- or control-vector. Subsequently, total RNA was collected and processed for analysis using Affymetrix microarrays. Three independent replicates were prepared for each comparison group.
