Project description:LncRNAs are key regulatory molecules involved in a variety of biological process and human diseases. However, the pathological effects of lncRNAs on primary varicose great saphenous veins (GSVs) remain unclear. In this study, we aimed at identifying aberrantly expressed lncRNAs involved in the prevalence of GSV varicosities and exploring their potential regulating effects. 6 paired tissues of the varicose great saphenous vein patient were used to compare the expression differences between varicose veins (VVs) and adjacent normal segments of saphenous veins (NVs) in the study. The lncRNA and mRNA expression profile of 6 paired vein tissues were studied using the microarry.

Project description:Serum-starved, quieced HSVSMC (human saphenous vein smooth muscle cells, isolated from the great saphenous vein of coronary artery bypass graft patients) were treated with recombinant human TGFbeta-1 (10ng/mL) in the presence or absence of ALK5 kinase inhibitor SB-525334 (10uM) or ALK1/2 kinase inhibitor KO2288, https://doi.org/10.1371/journal.pone.0062721, (10uM). Gene expression analysis was performed on RNA extracted from cells at the 24h timepoint. RNA samples from three independent experiments (performed on cells from three different patients) were analysed. Quiesced, unstimulated cells were used as a negative control.

Project description:To further understand the mechanism approach to occlusive vein grafts, we have employed RNA-seq to identify key genes in occlusive venin grafts following CABG in human. The occluded vein graft and intraoperative spare great saphenous vein of patients undergoing clinical re-coronary artery bypass grafting were obtained for RNA-seq. The sequencing results were cleaned and bioinformatics annlysis was conducted by using WGCNA and a variety of online databases and software. The key genes or proteins affecting the occurrence of vein graft restenosis were screened out(ITGB2), and the expression level of the target genes or proteins was verified by real-time PCR and Western blot. And to further learn the effect of ITGB2 in human primary venous smooth muscle cells, ITGB2 gene was silenced by SiRNA. The effect of ITGB2 silencing on proliferation, migration and invasion of venous smooth muscle cells after PDGF-BB-stimulation were detected by Edu assay, scrathch experiment and transwell experiment. And Edu assay showed that ITGB2 silencing could inhibit the proliferation of PDGF-BB sitmulated smooth muscle cells. Scratch assay showed that ITGB2 silencing inhibited the migration of PDGF-BB stimulated smooth muscle cells. Transwell assay showed that ITGB2 silencing significantly inhibited the invasion of PDGF-BB stimulated smooth muscle cells. It is indicated that ITGB2 was the key gene in vein graft restenosis,and may be the potential treatment target in restenosis patients.

Project description:Smooth muscle cell (SMC) phenotypic switching from a contractile to a synthetic state is implicated in diverse vascular pathologies, including neointimal formation. This study was designed to identify lncRNAs that may play a role in vascular pathologies. Primary smooth muscle cells cultured from surplus human saphenous vein tissue were treated with inflammatory and proliferative stimuli, IL1α and PDGF, for 72h and RNA extracted for RNA-sequencing. Using edgeR processed data we found expression of many lncRNAs was altered following treatment and could play a role in vascular disease.

Project description:Human ES or iPS Cells were differentiated into endothelial cells (ECs) defined by expression of CD31 (PECAM1) and CD144 (VE-Cadherin) on the cell surface. All ES or iPS derived ECs were greater than 90% double positive for these two markers. These in vitro derived ECs were compared to each other and to ECs from primary cell sources; arterial (aortic Ecs), venous (saphenous vein) and lymphatic.

Project description:Proliferation of vascular smooth muscle cells (vSMCs) following injury is a crucial factor contributing to pathological vascular remodelling. MicroRNAs (miRNAs) are powerful gene regulators and attractive therapeutics agents. Here, we aim to systemically identify and characterise miRNAs with therapeutic potential in targeting aberrant vSMC proliferation. We performed a high-throughput in vitro screen using a library of 2042 human miRNA-mimics for their impact on VSMC proliferation and identified seven novel antiproliferative miRNAs i.e miR-1827, miR-4774-3p, miR-5681b, miR-449b-5p, miR-491-3p, miR-323a-3p, and miR-892b.Overexpression of these 7 miRNAs affects proliferation of vSMCs from different vascular beds. Focusing on vein graft failure, a condition in which miRNA based therapeutics can be applied to the graft ex-vivo, we showed that these miRNAs reduced human saphenous vein SMC (HSVSMC) proliferation without inducing apoptosis or senescence, and five of them also significantly decreased migration.In contrast to HSVSMC, miRNA overexpression on saphenous vein endothelial cells (ECs) led to no or lower decrease of proliferation for the seven miRNAs. We performed RNA-seq on HSVEC overexpressing the seven miRNAs and showed a limited response of ECs to the miRNA overexpression.

Cells were quiesced in 0.2% serum for 48h followed by addition of 10ng/ml IL1α , 20ng/ml PDGF or both 10ng/ml IL1α and 20ng/ml PDGF together. Cells were collected after 72h and RNA extracted using Qiagen RNeasy kits. RNA-sequencing was carried out by Beckman Coulter Genomics on the r-RNA depleted fraction.

Project description:The locational predisposition of vascular pathologies illustrates the need for a better insight into vascular heterogeneity. To investigate the transcriptomic basis of angiodiversity, we isolated and analyzed transcriptomes from endothelial cells and vascular smooth muscle cells from nine different adult canine macrovessels: the aorta, coronary artery, vena cava, portal vein, femoral artery, femoral vein, saphenous vein, pulmonary vein, and pulmonary artery. We identified both reported and novel expression patterns defining specialized adult blood vessels. Our findings also show that adult vascular cells in culture express a remarkably high number of transcription factors crucial to organ development in the embryo. The persistent expression of these genes in culture indicates that these genes are not regulated by the flow or surrounding cell types but are rather fixed in the molecular memory. Therefore, our findings prompt the re-thinking of the extrapolation of results from single-origin endothelial cell systems.
