Project description:Transcriptomic analysis of targets regulated by miR-125b in primary endothelial cells
| PRJNA125811 | ENA
Project description:Human vein umbilical endothelial cells (HUVEC) were transfected with pre-miR control and pre-miR 146 (Ambion) in order to identify targets (direct and indirect) downregulated by miR-146a in endothelial cells. 164 transcripts were downregulated with a fold change ≥ 1.2. Total RNA was obtained from cells transfected in HUVEC with pre-miR control and pre-miR 146a. Three independent transfections were performed for each condition. 2 replicates for control re-control and 3 for pre-miR 146a were analyzed.

Project description:Endothelial cells are critical for angiogenesis, and microRNAs plays important roles in this process. We investigated the regulatory role of microRNAs in endothelial cells of hepatocellular carcinoma (HCC) by examining the microRNA expression profile of human umbilical vein endothelial cells (HUVECs) in the absence or presence of human HCC cells, and identified miR-146a as the most highly up-regulated microRNA. Furthermore, we revealed that miR-146a promoted the expression of platelet-derived growth factor receptor (PDGFRA) in HUVECs, and this process was mediated by BRCA1. Overexpression of PDGFRA in the ECs of HCC tissues was associated with microvascular invasion, and predicted a poorer prognosis. These results suggest that MiR-146a plays a key role in regulating the angiogenic activity of ECs in HCC through miR-146a-BRCA1-PDGFRA pathway. MiR-146a may emerge as a potential anti-angiogenic target on ECs for HCC therapy. We have employed whole genome OneArray to examine the genome expression changes of HUVECs overexpressing miR-146a.

Project description:This study was designed to explore the role of miRNA-146a (miR-146a) and its target genes in the endothelial cells. In this study we have demonstrated that lipopolysaccharide (LPS) induced upregulation of miR-146a in the human umbilical vein endothelial cells (HUVEC) and the induction was blocked by the silencing of the toll-like receptors (TLRs) adaptor molecules MyD88 and nonspecific NF-κB inhibitor BAY 11-7082. In addition, knockdown of miR-146a by transfection of the locked nucleic acid (LNA)-antimiR-146a significantly decreased the increased cell migration and tube formation induced by LPS. A combined analysis of the bioinformatics miRanda algorithms and the whole genome expression microarray of the immunoprecipitated Ago2 ribonucleoprotein complex identified 14 transcripts as the potential target genes. Subsequent transfection with miR-146a precursor pre-miR-146a into the HUVEC validated that the CARD10 was the target gene of the miR-146a both in the transcript and protein level.

Project description:We have found expression of miR-146a up-regulated in gastric cancer. To identify new targets of miR-146a we profiled the transcriptome after miR-146a over-expression in the human gastric cancer cell line SNU638. SNU638 cells were transfected in triplicates with 50 nM miR-146a or control (siGlo) using Lipofectamine 2000. Total RNA was harvested 24 h after transfection using Trizol reagent. There are a total of six arrays included in this experiment, including three biological replicates of mRNA expression after miR-146a over-expression and three controls in SNU638 cells.

Project description:5d IL-7-supported bone marrow cultures from C57BL/6 mice deficient for either the transcription factor Bob1 or microRNA-146a Micro-RNAs (miRNAs) are required for many processes during hematopoietic development and activation, including B-cell differentiation. The lymphocyte-specific transcription factor Bob1 is critical for the proper development and function of B cells. Bob1-/- mice are immunodeficient and lack germinal centers. Microarray expression analysis of Bob1-deficient B cells shows numerous up-regulated genes, suggesting that Bob1 may affect targets indirectly via the control of miRNAs. Using a gain-of-function/loss-of-function approach in WEHI-231 and primary pro-B and pre-B cells, we identified miR-146a as a direct target of Bob1. Ttranscriptome-wide analysis of miR-146a-/- B cells shows a number of misregulated genes involved in immune regulation, while analysis of Bob1-/- cells shows increased expression of cell cycle-related genes. These results support previous evidence that Bob1 suppresses proliferation, a previously underappreciated role for Bob1 that is in line with the cancer-prone phenotype of mir-146a-/- mice. 8 samples in total; 2 biological duplicates each of Bob1wt, Bob1KO, wild-type C57BL/6Ncrl, and mir-146aKO
