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

ABSTRACT: 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.

Cancer stem cells (CSCs) have been identified in various types of cancer; however, the mechanisms by which cells acquire CSC properties such as drug resistance and tumour seeding ability are not fully understood. Here, we identified microRNA-27b (miR-27b) as a key regulator for the generation of a side-population in breast cancer cells that showed CSC properties, and also found that the anti-type II diabetes (T2D) drug metformin reduced this side-population via miR-27b-mediated repression of ect ...[more]

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.

miR-27b synergizes with anticancer drugs

Project description:Drug resistance, caused by complex and redundant mechanisms, is a major obstacle in cancer treatment, especially in liver and kidney cancers. Combinational therapy of miRNAs, which concurrently target multiple pathways, with anticancer drugs represent a new strategy to improve the drug response. By a systems approach, we identified that miR-27b, a miRNA deleted in liver and kidney cancers, sensitizes cancer cells to a broad spectrum of anticancer drugs in vitro and in vivo. Two samples transfected with nontarget miRNA control or miR-27b mimics followed by 48 hours doxorubicin treatment

The effect of knocking down miR-27b on DIV14 mouse cortical neurons

Project description:To understand the effect of reducing miR-27b levels on genome-wide expression in cortical neurons and identify potential targets of miR-27b, we generated dissociated cortical neuron cultures and treated them with lentivirus to knock down miR-27b. 2 treatment conditions (control lentivirus or lentivirus to knock down miR-27b); 3 neuronal preparations of dissociated mouse cortical neurons; total of 6 samples

Gene expression analysis of THP-1 cells (monocytic cell line) transfected with microRNA mimics: let-7d-5p, miR-27b-3p, miR-151a-5p.

Project description:In our previous study, hsa-let-7d-5p,hsa-miR-27b-3p,hsa-miR-151-5p were significantly upregulated in the plasma of atopic patients. To study the each function of hsa-let-7d-5p,hsa-miR-27b-3p,hsa-miR-151-5p, which are significantly upregulated in the plasma of atopic patients, we performed mimic-transfected THP-1 cells, a mononuclear cell line, and performed comprehensive genetic analysis.

Heart mRNA profiles of TAC 8-weeks wild type (WT) and miR-27b-3p knockout mice

Project description:Aim: The heart undergoes pathological remodelling under increased stress and neuronal imbalance. MicroRNAs (miRNAs) are involved in post-transcriptional regulation of genes in cardiac physiology and pathology. However, the mechanisms underlying miRNA-mediated regulation of pathological cardiac remodelling remain to be studied. This study aims to explore the function of endogenous microRNA-27b-3p (miR-27b-3p) in pathological cardiac remodelling. Methods and results: We found that miR-27b-3p expression was elevated in heart of patients with cardiac hypertrophy and in transverse aortic constriction (TAC)-induced cardiac hypertrophy mouse model. MiR-27b-3p-knockout mice showed significantly attenuated cardiac hypertrophy, fibrosis, and inflammation induced by two independent pathological cardiac hypertrophy models, TAC and Angiotensin II (Ang II) perfusion. Transcriptome sequencing analysis revealed that miR-27b-3p deletion significantly downregulated TAC-induced cardiac hypertrophy, fibrosis, and inflammatory genes. We identified fibroblast growth factor 1 (FGF1) as a novel miR-27b-3p target gene in the heart, which was upregulated in miR-27b-3p-null mice. Conclusions: Our study has demonstrated that miR-27b-3p induces pathological cardiac remodelling and suggests that inhibition of endogenous miR-27b-3p or administration of FGF1 might have the potential to suppress cardiac remodelling in a clinical setting.

Effect of microRNA-27b-3p mimic treatment on human osteoarthritis fibroblast-like synoviocyte gene expression profiles

Project description:OBJECTIVE: To identify the changes in gene expression elicited by miR-27b-3p mimic transfection of human osteoarthritis (OA) primary fibroblast-like synoviocytes (FLS) obtained from patients undergoing knee arthroplasty. Cells were cultured, and treated for 48 h with miR-27b-3p mimic or Cel-miR-39-3p control mimic. Total RNA was then extracted, and mRNA libraries were prepared using Illumina's TruSEQ stranded total RNA library preparation kit, pooled together, and sequenced on Illumina's NextSeq550.
