4TO7 cells: miR-23b/27b/24 overexpression vs control

ABSTRACT: Transcriptional profiling of 4TO7 cells featuring ectopic expression of miR-23b/27b/24 compared to vector control cells. Gene expression changes will be examined as potential direct targets of the miRNAs for use in later studies on metastasis suppression or activation.

MiR-23b/-27b Targets in Prostate Cancer Cell Lines

MiR-23b/-27b Targets in Prostate Cancer Cell Lines

Project description:Analysis of genes regulated by miR-23b/-27b overexpression in aggressive PC3-ML cells, confirmed by antagomiR inhibition of miR-23b and miR-27b in the relatively indolent cell line LNCaP. Genes that were downregulated in PC3-ML overexpression and upregulated with LNCaP inhibition were further explored as downstream targets of miR-23b/-27b. PC3-Ml cells were transduced with miR-23b/-27b or a scrambled miRNA control, and only cells expressing greater than 95% transduction efficiency were used for array. LNCaP cells were transfected with antagomiRs to miR-23b and miR-27b, or a non-coding control.

Dysregulation of a miR-23b/27b-p53 axis impairs muscle differentiation in humans with type 2 diabetes

Project description:Impaired skeletal muscle function is a central feature in the pathophysiology of type 2 diabetes (T2DM). The disease phenotype could be due to immature muscle cell development, which in turn may occur as the result of disturbed microRNA-mediated regulation of muscle differentiation in T2DM. To address this hypothesis, we assessed global miRNA expression during in vitro differentiation of muscle stem cells derived from T2DM patients and healthy controls. We identified the mir-23b/27b cluster to be downregulated in the patients, and further demonstrated that a pro-myogenic effect of these miRNAs occurs through targeting of several genes in the p53 pathway, which was concordantly dysregulated in the muscle cells derived from humans with T2DM. In conclusion, we have identified a novel myogenesis-controlling pathway, the miR-23b/27b-p53 axis, potentially contributing to the sustained multiple muscular dysfunctions in T2DM in humans.

Identification of microRNA-27b target genes in breast cancer cell lines

Project description:To identify the microRNA-27b (miR-27b) target genes in luminal-type breast cancer cells, we performed the microarray analysis using miR-27b knockdown MCF7-luc cell line (MCF7-luc anti-miR-27b), miR-27b overexpressing MCF7-luc cell line (MCF7-luc miR-27b o.e.) and their contro cell line (MCF7-luc anti-NC). After establishing MCF7-luc anti-miR-27b, MCF7-luc miR-27b o.e. and MCF7-luc anti-NC using lentivirus vector, we performed the microarray analysis.

Global changes in gene expression in response to miR-200 overexpression in 4TO7 cells

Project description:Transcriptional profiling of 4TO7 cells stably overexpressing miR-200s or CDH1. We observe a dramatic shift in the gene signatures when miR-200s (cluster 2; miR-200c/141, or both clusters) are overexpressed relative to controls. However, cluster 1 overexpression (miRs-200b/a/429) alone or CDH1 overexpression does not induce global changes in gene expression to levels observed for cluster 2 (miR-200c/141) or both clusters together. One cell line (4TO7) cells: four different overexpression experiments, Cluster 1, Cluster 2, Clusters 1+2, CDH1, and respective controls, Puro vec, Hygro vec, Puro+Hygro vec and Puro vec. Each experiment has two biological replicates. Total, 16 samples.

RNA-seq in breast cancer cell lines after manipulation of miR-23b expression

Project description:RNA sequencing technology has been carried out in order to evaluate mRNA expression changes after manipulation of miR-23b in both MCF-7 and MDA-MB-231 breast cancer cell lines Our study implicates miR-23b in cytoskeletal remodeling in breast cancer. To evaluate the entire set of genes modulated by miR-23b we performed RNA-seq after ectopic manipulation of this miRNA in breast cancer cell lines. We over-expressed this miRNA in MCF-7 epithelial cancer cell lines and also reduced its activity by stably transfecting MDA-MB-231 mesenchymal-like cancer cell lines with a specific sponge vector. RNA-seq analysis revealed a number of candidate targets of this miRNA.
