Project description:We report the application of transcriptome sequencing for investigating of the hsa-miR-371a-5p and hsa-miR-518a-3p regulated genes. JAR, JEG-3 and BeWo choriocarcinoma cells were transfected with hsa-miR-371a-5p or hsa-miR-518a-3p inhibitors or control inhibitors. Totally, 237, 132 and 277 genes with > 2 folds change and adjusted P < 0.05 were upregulated in JAR, JEG-3 and BeWo cells respectively after hsa-miR-371a-5p knockdown. Meanwhile, 229, 269 and 191 genes were upregulated in JAR, JEG-3 and BeWo cells respectively after hsa-miR-518a-3p knockdown. The top upregulated genes included many oncogenes or oncogenesis associated ones. Enrichment analysis showed hsa-miR-371a-5p and hsa-miR-518a-3p regulated diverse pathways related to tumorigenesis and metastasis. Our results would be helpful for the searching of early molecular biomarkers and therapeutic targets for gestational trophoblastic neoplasia.

Project description:miR-493-5p, miR-3662, and miR-589-3p were estimated as working microRNAs in bleomycin- and methotrexate-induced phenotypic changes in A549 cells via microRNAs-Proteins Analysis of Integrative Relationship (miR-PAIR). To verify the effect of these miRNAs on the their target protein expression levels, comprehensive expression of proteins in A549 cells treated with miR-493-59, miR-3662, and miR-589-3p mimic was examined by SWATH-MS method. As expected by a miR-PAIR mehtod, almost target proteins were succesfully regulated by miR-493-5p and miR-589-3p mimics.

Project description:Hematopoietic stem/progenitor cells (HS/PCs) were transduced with lentiviral vectors overexpressing OFP and either miR-511-3p or a control, mutated miRNA sequence (miR-511-3p-mut). The transduced HS/PCs were then transplanted in recipient C57BL/6 mice. Tumors (Lewis lung carcinomas, LLC) were injected s.c. 4 weeks after HS/PC transplant. Lentiviral vector-transduced (OFP+), tumor-associated macrophages (TAMs) were isolated 4 weeks after LLC injection by fluorescence-activated cell sorting. Gene expression profiles of TAMs overexpressing either miR-511-3p or miR-511-3p-mut were obtained from 3 independent biological samples/each. Gene expression profiles of miRNA-overexpressing TAMs were then compared with the gene expression profiles of wild-type TAMs isolated from LLCs grown in nontransplanted C57BL/6 mice; the latter TAMs were subfractioned into MRC1+CD11c(low) or CD11c+MRC1(low) subsets before RNA isolation and analysis. Comparison of gene expression profiles of TAMs revealed that miR-511-3p overexpression tunes down the expression of multiple genes that are classically upregulated in protumoral MRC1+CD11c(low) TAMs. TAMs were isolated from Lewis lung carcinomas grown s.c. in C57BL/6 mice.

Project description:As recently reported by our group, we performed miRNA and gene expression profiling of CD34+ hematopoietic stem/progenitor cells (HSPCs) isolated from 42 PMF patient samples compared with 31 healthy controls. Integrative analysis of these profiles by means of Ingenuity Pathway Analysis (IPA) allowed the identification of several aberrantly regulated miRNA-mRNA target pairs organized in interaction networks. In particular, our results highlighted the up-regulation of miR-494-3p in CD34+ cells from PMF patients (Norfo R et al, Blood, 2014). Interestingly, among the most upregulated miRNAs, miR-494-3p emerges as being associated to the highest number of downregulated target mRNAs. In order to understand the biological role of miR-494-3p during the hematopoietic commitment and differentiation, we overexpressed this miRNA in cord blood (CB) derived-CD34+ cells. Cells were electroporated with either miR-494-3p miRNA mimic (mimic miR-494) or a negative control mimic (mimic Neg CTR). qRT-PCR confirmed miR-494-3p overexpression 24h and 4 days after transfection (RQ ± SEM, 512.60 ± 137.37, p<.01, and 20.63 ± 3.03, p<.01, respectively). Immunophenotypic analysis of CD41 and CD42b megakaryocyte (MK) lineage differentiation markers, performed on serum-free megakaryocytic ultilineage culture at day 3, 5, 8, 10 and 12, demonstrated that miR-494-3p overexpression induces a significant increase in the MK fraction compared to control samples. Accordingly, morphological analysis of May-Grünwald-Giemsa stained cytospins revealed an expansion of megakaryocytic lineage in samples overexpressing miR-494-3p. These data were further confirmed by collagen-based clonogenic assays which showed a significant increase in the percentage of megakaryocytic colonies in miR-494-3p overexpressing samples compared with controls. In order to better characterize the molecular mechanisms underlying the effects of miR-494-3p on HSPCs differentiation, we performed gene expression analysis of miR-494-3p overexpressing cells 24 hours after the last nucleofection.

Project description:The transcription factor c-Myb plays a key role in human primary CD34+ hematopoietic progenitor cells (HPCs) lineage choice, by enhancing erythropoiesis at the expense of megakaryopoiesis. We previously demonstrated that c-Myb affects erythroid versus megakaryocyte lineage decision in part by transactivating KLF1 and LMO2 expression. To further unravel the molecular mechanisms through which c-myb affects lineage fate decision, we profiled the miRNA and mRNA changes in myb-silenced CD34+ HPCs. The integrative analysis of miRNA/mRNA expression changes upon c-myb silencing in human CD34+ HPCs highlighted a set of 19 miRNA with 150 anticorrelated putative target mRNAs. Among the miRNAs downregulated in myb-silenced progenitors with the highest number of predicted target mRNAs, we selected hsa-miR-486-3p based on the in vitro effects of its overexpression on HPCs commitment. Indeed, morphological and flow cytometric analyses after liquid culture showed that hsa-miR-486-3p overexpression in HPCs enhanced erythroid and granulocyte differentiation while restraining megakaryocyte and macrophage differentiation. Moreover, collagen-based clonogenic assay demonstrated a strong impairement megakaryocyte commitment upon hsa-miR-486-3p overexpression in CD34+ cells. Moreover, in order to identify the mRNA target through which hsa-miR-486-3p affects lineage fate decision, we profiled the mRNA changes in mimic transfected CD34+ HPC by means of Affymetrix GeneAtlas U219 strip array. Gene expression profiling of hsa-miR-486-3p overexpressing CD34+ cells enabled us to identify a set of 8 genes downregulated and computationally predicted, putative hsa-miR-486-3p targets. Among them, we selected c-maf transcript as upregulated upon myb silencing. Worth of note, c-maf silencing in CD34+ progenitor cells was able to reverse the affects of myb silencing on erythroid versus megakaryocyte lineage choice. Integrative miRNA/mRNA analysis highlighted a set of miRNAs and anticorrelated putative target mRNAs modulated upon myb silencing, therefore potential players in myb-driven HPCs lineage choice. Among them, we demonstrated the hsa-miR-486-3p/c-maf pair as partially contributing to the effects of myb on HPCs commitment. Therefore, our data collectively identified myb-driven hsa-miR-486-3p upregulation and subsequent c-maf downregulation as a new molecular mechanism through which cMyb favours erythropoiesis while restraining megakaryopoiesis. Gene expression profile (GEP) was performed on total RNA derived from three independent experiments at 24h after the last nucleofection.
