Project description:We used a multi-omics approach to study the impact of miR-223 in the RAW cell line. We evidenced changes linked to cell death, histone acetylation, bone remodeling, RNA regulation. Changes in miR-223 expression altered the metabolic profile of cells including nucleotides. miR-223 impacted NF-kB levels, macrophage differentiation and osteoclastogenesis.

Project description:We used a multi-omics approach combining transcriptomics, proteomics and metabolomics to study the impact of over-expression and inhibition of the microRNA miR-223, a pleiotropic regulator of metabolic-related disease, in the RAW monocyte-macrophage cell line. We analyzed the levels of proteins, mRNAs, and metabolites in order to identify genes involved in miR-223 regulation, to determine candidate disease biomarkers and potential therapeutic targets. We observed that both up- and down-regulation of miR-223 induced profound changes in the mRNA, protein and metabolite profiles in RAW cells. Microarray-based transcriptomics evidenced a change in 120 genes that were linked predominantly to histone acetylation, bone remodeling and RNA regulation. In addition, 30 out the 120 genes encoded long noncoding RNAs. The nanoLC-MS/MS revealed that 52 proteins were significantly altered when comparing scramble, pre- and anti-miR-223 treatments. Sixteen out of the mRNAs coding these proteins genes are predicted to have binding sites for miR-223. CARM-1, Ube2g2, Cactin and Ndufaf4 were confirmed to be miR-223 targets by western blotting. Analyses using Gene Ontology annotations evidenced association with cell death, splicing and stability of mRNAs, bone remodeling and cell metabolism. miR-223 alteration changed the expression of CARM-1, Ube2g2, Cactin and Ndufaf4 during osteoclastogenesis and macrophage, indicating that these genes are potential biomarkers of these processes. The most important discriminant metabolites found in the metabolomics study were found to be hydrophilic amino acids, carboxylic acids linked to metabolism and pyrimidine nucleotides, indicating that changes in miR-223 expression alter the metabolic profile of cells, and may affect their apoptotic and proliferative state.

Project description:Microvesicles (MV) are small membrane-bound particles comprised of exosomes and various sized extracellular vesicles. These are released by a number of cell types. Microvesicles have a variety of cellular functions from communication to mediating growth and differentiation. Microvesicles contain proteins and nucleic acids. Previously, we showed that plasma microvesicles contain microRNAs (miRNAs). Based on our previous report, the majority of peripheral blood microvesicles are derived from platelets while mononuclear phagocytes, including macrophages, are the second most abundant population. Here, we characterized macrophage-derived microvesicles and whether they influenced the differentiation of naïve monocytes. We also identified the miRNA content of the macrophage-derived microvesicles. We found that RNA molecules contained in the macrophage-derived microvesicles were transported to target cells, including monocytes, endothelial cells, epithelial cells and fibroblasts. Furthermore, we found that miR-223 was transported to target cells and was functionally active. Based on our observations, we hypothesize that microvesicles bind to and activate target cells. Furthermore, we find that microvesicles induce the differentiation of macrophages. Thus, defining key components of this response may identify novel targets to regulate host defense and inflammation. We used GeneChip microarrays to examine changes in gene expression induced by MV in primary monocyte-derived macrophages (MDM) and in THP1 cells, and compare this to cells treated with GM-CSF and PMA, respectively.

We used GeneChip microarrays to examine changes in gene expression induced by MV in primary monocyte-derived macrophages (MDM) and in THP1 cells, and compare this to cells treated with GM-CSF and PMA, respectively. All experiments were done in triplicates. Primary monocytes were collected from buffy coats (BC). The freshly isolated monocytes from three donors (Mono1-3) were either treated with GM-CSF or subjected to RNA isolation. Following treatment, MVs were isolated from the GM-CSF-treated macrophage cultures. RNA was isolated from the remaining cells for profiling (GM1-3). The isolated MVs were then used to treat new BC monocytes for 24 h (BC-GMCSF-MV24). A fraction of the new BC monocytes was subjected to RNA extraction for profiling (BC1-3). For THP1 cells, they were treated with either DMSO or PMA to produce MVs. The MVs were collected and the remaining cells lyzed for RNA extraction and profiling (DMSO1-3 and PMA1-3). The collected MVs from the DMSO or PMA-treated THP1 cells were incubated with new THP1 for 24 h and designated DMSO-MV24 or PMA-MV24. We had a total of 24 samples.

Project description:miR-223 is step-wise increasingly up-regulated in the normal esophagus - Barrett's esophagus -esophageal adenocarcinoma carcinoma sequence. In this study, we aimed to determine the function of miR-223 in esophageal adenocarcinoma carcinogenesis. miR-223 was transfected in OE33 cells using 10nM pre-miR hsa-miR-223 miRNA precursor (Ambion, Life Technologies, Grand Island, NY) and lipofectamin 2000 (OE33_223_1 and OE33_223_2). Mock control OE33 cells were transfected with a negative control pre-miR miRNA (OE33_NEG_1 and OE33_NEG_2). HumanHT-12 v4 Expression BeadChip arrays (Illumina, San Diego, CA) were used for microarray hybridizations to examine the global gene expression of two biological replicated experiments (four samples in total). The array targets more than 25,000 annotated genes with 47,323 unique probes derived from the National Center for Biotechnology Information (NCBI) Reference Sequence (RefSeq) Release 38 and UniGene (Build 199) databases.
