Project description:strand specific sequencing of RNAs from MAoECs to determine the endothelial-specific expression profile of protein-coding and long non-coding RNAs
Project description:Calcific aortic valve disease (CAVD) is the most common valvular heart disease in the aging population, ranging from initial aortic valve sclerosis to advanced aortic valve stenosis (AVS), but its underlying mechanism remains poorly understood. The present study aimed to explore the differentially expressed long non-coding RNAs and genes in CAVD.
Project description:Analysis of primary bovine aortic endothelial cells treated for 24 hours with TGF-beta 1 5 ng/ml. TGF-beta 1 has been shown to induce endothelial-to-mesenchymal transition (EndoMT) and to be implicated in differentiation of endothelial cells into smooth muscle-like cells as occurred in vascular neointimal formation. Primary aortic endothelial cells seeded on 10 mm diameter plates were incubated with TGF-beta 1 (5 ng/ml) for 24 hours or left under basal conditions. Triplicates from three different cultures.
Project description:Human aortic endothelial cells were stimulated by lysophosphatidylcholine (LPC) (10μM) with or without interleukin 35 (IL-35) (10ng/mL) or IL-10 (10ng/mL) for 18 hours. Total RNAs were extracted from samples, then mRNA and non-coding RNAs were enriched by removing rRNA from the total RNA. The library was sequenced by Illumina HiSeq4000 using PE100 strategy and the reads were mapped to the human hg19 reference genome.

Project description:Porcine aortic and aortic valve endothelial cells were exposed to 20 dynes/cm2 steady laminar shear stress with static cultures serving as controls. Total RNA was hybridized to Agilent Human 1 cDNA arrays and processed using the Agilent Feature Extraction Software Keywords = aortic valve Keywords = endothelial Keywords = shear stress Keywords: other
Project description:To characterize the transcriptome of primary vascular endothelial cells (ECs) during TNFα-response, we performed total RNA-seq on primary human aortic ECs (HAEC), before and after TNFα (45 min. 10 ng/mL).
Project description:Hypoxia is human atherosclerotic lesions and has multiple adverse effects on endothelial cell metabolism. Recently, key roles of long non coding RNAs (lncRNAs) in the development of atherosclerosis have begun to emerge. In this study, we investigated the long non-coding RNA profiles of HUVECs subjected to hypoxia using GRO-Seq. We demonstrate that hypoxia regulates the nascent transcription of ~1800 lncRNAs. Interestingly, we provide evidence that promoter associated lncRNAs are more likely to be induced by hypoxia compared to enhancer associated lncRNAs which exhibit equal distribution of up- and downregulated transcripts. We also found that hypoxia leads to significant induction in the activity of superenhancers next to genes and transcription factors implicated in angiogenesis, cell survival and adhesion whereas superenhancers near regulators of peptidyl-tyrosine dephosphorylation, signal transduction and GTPase activity were repressed. Despite majority of lncRNAs exhibiting low detection in RNA-Seq, a subset of lncRNAs were expressed at comparable levels to mRNAs. Among these MALAT1, HYMAI, LOC730101, KIAA1656 and LOC339803 were found differentially expressed in human atherosclerotic and may thus serve as potential biomarkers for lesion hypoxia.
