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

ABSTRACT: 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.

Genome-wide methylation and expression analysis of two breast cancer cell lines [RNA-Seq]

Project description:To improve our understanding of the relationships between methylation and expression we profiled mRNA expression and single-base resolution methylation levels for two breast cancer cell lines, MCF7 and T47D. Expression was profiled using RNA-seq. Methylation was assayed using Methyl-MAPS, which uses methylation-sensitive and -dependent restriction enzyme digests followed by high-throughput sequencing to identify methylation levels at individual CpGs (Edwards et al. 2010, Genome Research). RNA-Seq was used to generate mRNA expression profiles of MCF7 and T47D cells under standard growth conditions.

RNA-sequencing (RNA-seq) in breast cancer cell lines after ectopic manipulation of miR-26a expression

Project description:RNA sequencing technology has been carried out in order to evaluate mRNA expression changes after manipulation of miR-26a in both MCF-7 and MDA-MB-231 breast cancer cell lines. To evaluate the entire set of genes modulated by miR-26a in breast cancer, we performed RNA-seq after ectopic manipulation of this miRNA. We over-expressed miR-26a 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. GO terms and pathway enriched analysis of the transcripts that significantly change upon miR-26 ectopic manipulation implicates miR-26ab in cell cycle, apoptosis, cell spreading and cell adhesion in breast cancer

RNA-seq transcriptome analysis of breast cancer cell lines under shikonin treatment.

Project description:Shikonin is a naphthoquinone isolated from the dried root of Lithospermum erythrorhizon, an herb used in Chinese medicine. Although several studies have indicated that shikonin exhibits antitumor activity in breast cancer, the mechanism of action remains unclear. In the present study, we performed transcriptome analysis using RNA-seq and explored the mechanism of action of shikonin in regulating the growth of different types of breast cancer cells. The IC50 of shikonin on MCF-7, SKBR-3 and MDA-MB-231 cells were 10.3 μΜ, 15.0 μΜ, 15.0 μΜ respectively. Our results also demonstrated that shikonin arrests the progression of cell cycle and induces apoptosis in MDA-MB-231 cells. Using RNA-seq transcriptome analysis, we found 38 common genes that significantly express in different types of breast cancer cells under shikonin treatment. In particular, our results indicated that shikonin induces the expression of dual specificity phosphatase (DUSP)-1 and DUSP2 in both RNA and protein levels. In addition, shikonin also inhibits the phosphorylation of JNK and p38, the downstream signaling molecules of DUSP1 and DUSP2. Therefore, our results suggest that shikonin induces the expression of DUSP1 and DUSP2 which consequently switches off JNK and p38 MAPK pathways and causes cell cycle arrest and apoptosis in breast cancer cells.

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.
