Project description:Tumor progression is accompanied by an altered myelopoiesis that causes the accumulation of cells inhibiting anti-tumor T lymphocytes. We previously reported that immunosuppressive cells can be generated in vitro from bone marrow cells (BM) after four days GM-CSF and IL-6 treatment. Here, we describe that miR-142-3p down-regulation directs macrophage differentiation and determines the acquisition of their immunosuppressive function in cancer. Enforced miR over-expression impaired monocyte to macrophage transition both in vitro and in vivo. Conversely, forced miR down-regulation promoted the generation of immunosuppressive macrophages even during G-CSF-induced granulocytic differentiation. To identify how miR-142-3p regulates MDSC generation and activity, we analyze the gene expression of BM cultures transfected with either CTRL- or miR 142-3p mimic oligo -transfected before four days GM-CSF and IL-6 treatment. Keywords: Expression profiling by array

Keywords: Expression profiling by array BM cells were transfected either CTRL- or miR 142-3p mimic oligo before GM-CSF and IL-6 treatment to generate in vitro MDSCs during enforced miR over-expression. A triplicate of each sample was considered.Total RNA from obtained in vitro BM-differentiated MDSCs was isolated by Trizol reagent, and cRNA samples were hybridized to the Affymetrix GeneChip MOE430 2.0.
Project description:To investigate machanism of miR-210-3p regulating angiogenic ability of human umbilical vein endothelial cells (HUVECs) in hypoxic conditions, we transfected miR-210-3p mimic to overexpress miR-210-3p in human umbilical vein endothelial cells. We than performed RNA sequencing of miR-210-3p mimic-transfected and control HUVECs under hypoxic conditions to evaluate the transcriptional changes in the miR-210-3p-overexpressing HUVECs.
Project description:Bone marrow-derived macrophages were transfected with miRNA-204-3p mimics or mimics negative control for 24 hours. RNA-seq was performed to compare miR-204-3p overexpression versus control cells.
Project description:This experiment captures expression over 60,000 well-annotated RefSeq human transcripts over RNA samples from SH-SY5Y neuroblastoma cells transfected with human and non-human primate microRNA mimic variants of miR-299-3p, miR-503-3p, miR-508-3p and miR-541-3p, as well as a RNA duplex negative control (C2 mimic, Dharmacon).
Project description:Analysis of changes in gene expression after transfection with miR-552-3p or miR-608 mimic in A549 cells Total RNA was obtained from A549 cells transfected with miR-552-3p or miR-608 or negative control mimic, and gene expression was compared using microarrays.
Project description:We intended to investigate effects of mmu-miR-15a-3p on gene expression in mice We used microarrays to compare gene expression in mouse B/CMBA.Ov cell lines transfected with mmu-miR-15a-3p and negative control mimic
Project description:To identify the target of miR-4653-3p, mRNA microarray analysis was performed to compare mRNA expression between MIA PaCa-2 cells transfected with miR-4653-3p mimic and negative control cells.
Project description:To analyze the effect of miR-223-3p expression on the mRNA level we employed whole genome microarray expression profiling to identify genes with a potential seed region targeted by miR-223-3p. A549 cells were transfected for 48h with either a mirVana miRNA mimic Control or miR-223-3p.
