Transient transfection of miR-449 family in the hepatocellular carcinoma cell line HLE

ABSTRACT: In this study, we comparatively analyzed the members of the miR-449 family (miR-449a, miR-449b, and miR-449c) with regards to their target genes and functional effects in hepatocellular carcinoma (HCC). Microarray analysis after transient transfection of miR-449a, miR-449b, and/or miR-449c in the HCC cell line HLE identified putative target genes of miR-449a, miR-449b, and miR-449c.

Microarray analysis after transient transfection of miR-449a, miR-449b, and/or miR-449c in the HCC cell line HLE identified putative target genes of miR-449a, miR-449b, and miR-449c. For transient overexpression of miRNAs, the HCC cell line HLE was transfected with 50 nM Allstars Negative Control or miScript miRNA mimics. MiRNA mimics for miR-449a, miR-449b, and miR-449c were either single transfected or cotransfected in equimolar amounts (16.7 nM each). Global mRNA expression profiling was performed utilizing pooled RNA of three biological replicates per microarray and two microarrays per condition.

Transcriptomic impact of microRNAs-449 or microRNAs-34 overexpression in proliferating human airway epithelial cells

Project description:We used microarrays to detail the global programme of gene expression that occurs in response to miR-449 or miR-34 overexpression in proliferating HAECs. Each donors were transfected with pre-miR-Negative control, pre-miR-449a and pre-miR-449b. The donors 3 and 4 were morever transfected with pre-miRs-34 (34a, 34b-5p, 34c-5p).

NGS-based miRNome reveals regulation in the miR-34/miR-449 cluster targetome in sinonasal cancers [miRNA-seq]

Project description:Using NGS-based miRNome, followed by AGO2-RIP-seq, the miR-34c and miR-449a and their direct targets were identified as factors involved in the development and progression of sinonasal cancers (SNCs). Both miR-34c and miR-449a were independent prognostic biomarkers and were associated with patient outcome.

Gene expression signatures in HCC cell lines transfected with a miR-199a-3p mimic molecule

Project description:To clarify the role of miR-199a-3p in HCC, we carried out a gene expression microarray analysis using HCC cell lines (HLE and HLF) transfected with a miR-199a-3p mimic or a negative control. We found that 819 genes were downregulated (>2-fold) by miR-199a-3p in both cell lines.

Antiandrogen Flutamide-Induced Restoration of miR-449 Expression Mitigates Molecular Markers Associated with Ovarian Cancer Risk

Project description:The involvement of the androgen receptor (AR) pathway in the development of epithelial ovarian cancer is increasingly recognized. We examined the effects of the anti-androgen agent flutamide on miRNA expression in women at high risk (HR) for ovarian cancer. Flutamide treatment restored the reduced expression of miR-449a and miR-449b-5p in HR tissues, thereby decreasing CSF1R and AR expression associated with an increased risk of ovarian cancer. In addition to the known direct binding of flutamide to the AR, we found that flutamide also suppresses AR expression via miR-449a and miR-449b-5p upregulation, revealing a novel dual-inhibitory mechanism on the AR pathway. Taken together, our study highlights the chemopreventive potential of flutamide in ovarian cancer and suggests avenues for future research and clinical applications.

Proteomic analysis of genes regulated by miR-4510 in hepatocellular carcinoma

Project description:Patients with advanced hepatocellular carcinoma (HCC) are currently treated by Sorafenib and Regorafenib but efficacy of these multikinase inhibitors is disappointing. Thus, new drugs and therapies are needed to improve HCC management in clinic. We recently reported the remarkable capacity of miR-4510 to impede the growth of HCC and hepatoblastoma cells in vitro and in vivo through GPC3 targeting and Wnt pathway inactivation (Cartier F et al, Oncotarget 2017). Here, we used a label-free proteomic approach to identify new targets of miR-4510 in HCC-deriving Huh7 cells. We transfected HCC-derived Huh7 cells with either a synthetic miR-4510 mimic or a small RNA control, extracted total proteins 24hr later and comparatively analyzed proteomes of control and miR-4510-transfected cells using a quantitative label-free approach.

Gene expression changes in the respiratory epithelium of miR-34/449 knockout mice

Project description:MicroRNA ablation prevents multiciliogenesis via cell cycle deregulation MicroRNAs (miRNAs) have been implicated in various biological processes but have been most frequently described to inhibit proliferation and tumorigenesis. Here we describe an essential function of the miR-34/449 family during differentiation of multiciliated cells that is mediated by their well-described suppression of cell cycle progression. Constitutive deletion of all six members of this miRNA family triggers a derepression of multiple cell cycle-promoting proteins, thereby preventing epithelial cells from exiting the cell cycle and to maintain in a quiescent state. As a result, formation of motile multicilia is strongly inhibited in several tissues including the respiratory epithelium and the fallopian tube. Consequently, mice lacking miR-34/449 genes display infertility as well as severe chronic airway disease leading to postnatal death. These results show how miRNA-mediated repression of the cell cycle is required to allow multiciliogenesis to proceed during epithelial differentiation.
