MiR-148b modulates the expression of multiple genes

ABSTRACT: To identify which miR-148b targets were involved in tumorigenesis, a microarray analysis was performed for miR-148b over-expressing cells versus controls and 129 (49 up and 80 down) modulated genes were revealed.

miR-148b modulates the expression of multiple genes

Project description:To identify which miR-148b targets were involved in tumorigenesis, a microarray analysis was performed for miR-148b over-expressing cells versus controls and 129 (49 up and 80 down) modulated genes were revealed. The effects of miR-148b on cancer progression depend on the direct and indirect regulation of multiple target genes. To identify miR-148b modulated genes, MDA-MB-231 cells were transfected with miR-148b precursors or negative controls (pre-miR-148b or control) and used 48h later for microarray and western blot (WB) analyses. When a âWhole Human Genome Oligo Microarrayâ (Agilent) platform was employed, 129 differentially expressed genes (49 upregulated, 80 downmodulated) were found at 48h, considering a fold change (FC) cut of 1.5 and a false discovery rate (FDR) of 16% (Table S4). Crossing these results with the list of putative miR-148b targets (3642) obtained by the miRecords System, we observed that 33 of the modulated genes were also miR-148b predicted targets and interestingly, 26 out of these 33 genes were downmodulated.

miR-148b modulates the C1GALT1 expression explaining the abnormal glycosylation process in IgA Nephropathy

Project description:Immunoglobulin A nephropathy (IgAN) is the most common form of primary glomerulonephritis worldwide characterized by aberrant O-glycosylation in the hinge region of IgA1. The basis for the abnormal glycosylation in IgAN is still unknown, but an important involvement of the enzyme core 1, beta 1,3-galactosyltransferase 1 (C1GALT1) is known. However, the role of microRNAs (miRNAs), a new family of key mRNA regulatory molecules, in the IgAN pathogenesis has not yet been reported. In this study, by high-throughput microRNA profiling, we identified 37 miRNAs differentially expressed in peripheral blood mononuclear cells (PBMCs) from IgAN patients compared to healthy subjects. Among them, upregulated miR-148b potentially targeted C1GALT1, INVS and PTEN, three genes notably downregulated in IgAN patients. C1GALT1 expression levels in IgAN patients were reduced and negatively correlated with the upregulated miR-148b expression. We demonstrated the biological relationship between miR-148b and C1GALT1 by transient transfection experiments ex vivo. When we reduced the upregulated miR-148b function in PBMCs of IgAN patients an increase of the C1GALT1 mRNA and protein levels was observed. We validated biologically also the miR-148b targeting of INVS , involved in the altered modulation of the WNT–β-catenin and PI3K/Akt pathways in IgAN patients. All together our data evidence an important role of miR-148b in the pathogenesis of IgAN, which could explain the aberrant glycosylation of IgA1 in the pathogenesis and should light on a potential target for the theraphy of the disease.

Expression data from E10 cells with miR-129 over-expression

Project description:miRNAs are known to regulate gene expression by suppressing translation, but there is also a wealth of data showing that they can act as critical regulators of mRNA stability of their targets. In this experiment, we analyzed the mRNA expression profiles of E10 with high expression of miR-129 as compared to control cells to identify miR-129 targets. E10 cells infected with miR-129 over-expressing lentivirus or the control lentivirus were cultured for 48 hours. More than 80% of cells were infected. Total RNA samples were isolated using Trizol (invitrogen), and subjected to labeling, fragmentation and hybridization, according to manufacturer’s protocols. Mouse Genome 430 2.0 Array (Affymetrix) was used for mRNA expression profiling.
