Proatherogenic gene regulation explained by cell-type-specific miRNA profiling

ABSTRACT: Regulation of coding and non-coding genes is studied from primary human aortic endothelial cells (HAECs), venous endothelial cells (HUVECs), aortic smooth muscle cells (HASMCs) and macrophages (CD14+) under pro-atherogenic stimuli (hypoxia, oxPAPC and hypoxia+oxPAPC) by integrating three different sequencing techniques: GRO-seq, miRNA-seq and RNA-seq.

Evidence for the importance of OxPAPC interaction with cysteines in regulating endothelial cell function

Project description:Oxidation products of 1-palmitoyl-2-arachidonoyl-sn-glycerol-2-phosphatidylcholine (PAPC), referred to as OxPAPC, accumulate in atherosclerotic lesions and regulate over 1000 genes in human aortic endothelial cells (HAEC). We previously demonstrated that OxPAPC covalently binds to a number of proteins in HAEC. The goal of these studies was to gain insight into the binding mechanism and determine if binding regulates activity. In whole cells N-acetylcysteine inhibited gene regulation by OxPAPC, and blocking cell cysteines with N-ethylmaleimide strongly inhibited OxPAPC binding. Using MS, we demonstrate that most of the binding of OxPAPC to cysteine is mediated by PEIPC. We also show that OxPAPC binds to a model protein, H-Ras, at cysteines previously shown to regulate activity in response to 15dPGJ2. This binding was observed with recombinant protein and in cells overexpressing H-Ras. 15dPGJ2 and OxPAPC increased H-Ras activity at comparable concentrations. Using microarray analysis, we demonstrate a considerable overlap of gene regulation by OxPAPC and 15dPGJ2 in HAEC, suggesting that some effects attributed to 15dPGJ2 may also be regulated by OxPAPC since OxPAPC lipids and 15dPGJ2 both accumulate in inflammatory sites. Overall, we provide evidence for the importance of OxPAPC-cysteine interactions in regulating HAEC function. Control, OxPAPC, and 15dPGJ2-treated HAECs Samples. 'Control' is media (1%FBS, 99%M199)-only treated HAECs. 15dPGJ2 and OxPAPC are treated with those respective compounds in media.

ChIP-seq of H3K27acethylation of human aortic endothelial cells (HAECs) treated with Cobalt chloride (CoCl2)

Project description:Endothelial-to-mesenchymal transition (EndMT) is a fundamental process in vascular remodeling, and hypoxia is known to induce EndMT and involved in cardiovascular disease development. Cobalt chloride (CoCl2), a chemical inducer of hypoxia-inducible factor-1 (HIF-1) could influence cellular function and its differentiation. However, exact molecular mechanism how stabilization of HIF-1 by cobalt chloride in human primary ECs affects cellular behavior and EndMT process is largely unknown. In this study, we performed ChIP-seq for H3K27ac in human aortic endothelial cells (HAECs) treated with CoCl2

Transcription profiling of human aortic endothelial cells with miR-10a knock down

Project description:This study investigates the miR-10a-mediated transcriptome in human aortic endothelial cells (HAECs). The EC transcriptome was profiled in miR-10a knockdown HAECs. Specifically, small amounts of EC RNA were isolated from control cells and miR-10 knockdown cells expressing miRNA inhibitor control (Dharmacon) and miR-10a inhibitors (Dharmacon), respectively . Eight 2-channel assays comparing knockdown to control were performed using the Agilent Whole Human Genome Microarray 4x44K [G4112F].

NRF2 Controls Endothelial Plasticity with miR-93

Project description:Here we studied the role of oxidized phospholipids in mediating phenotype switching of endothelial cells between quiescent and angiogenic states. Two oxPAPC datasets, a microRNA array and global run-on sequencing (GRO-seq), was combined with Nuclear factor erythroid 2-Related Factor 2 (NRF2) binding model to select candidate miRNAs for further studies. The pre-screening resulted in a selection of miR-106b~25 cluster for further studies. The cluster was shown to be both oxPAPC-responsive and NRF2-regulated, and its diagnostic and prognostic potential was investigated in pericardial fluid samples of heart failure and atherosclerosis patients. As the most abundant member of the cluster in both endothelial cells and pericardial fluid of atherosclerosis patients, miR-93-5p was selected for more detailed studies. RNA-seq from miR-93 overexpressing cells revealed significant changes in pathways related to angiogenesis. Together with NRF2, miR-93 was shown to control endothelial plasticity through regulation of the key players, namely Krüppel-like factor 2 (KLF2) for quiescence, 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 (PFKFB3) for glycolysis, and Vascular Endothelial Growth Factor A (VEGFA), Forkhead box protein O1 (FOXO1) and MYC proto-oncogene protein (MYC) for growth and proliferation.The findings show that NRF2 and miR-93 control the activity of endothelial cells and mediate the effects of oxPAPC on endothelial activation, collectively providing novel mechanisms for the control of endothelial plasticity and oxPAPC response.

RNA-Seq of human aortic endothelial cells with lysophosphatidylinositol against untreated controls

Project description:Vascular Innate immune cells, such as macrophages, elicit long-term T cell-, and B cell- immune responses, by expressing danger-associated molecular pattern (DAMP) receptors, T cell co-stimulation receptors and presenting antigens to the adaptive system through major histocompatibility complex (MHC)-II. Here, we investigated whether human aortic endothelial cells (HAECs) could also be “transdifferentiated” into innate immune cells after treatment of hyperlipidemia-upregulated DAMP molecules, lysophosphatidylinositol (LPI). HAECs were treated with vehicle control or lysophosphatidylinositol (16:0) (10µM) for 18 hours.
