MiRNA profiling of human saphenous vein pericyte exosomes

ABSTRACT: Human saphenous vein perciytes (hSVPs) were proved increase angiogenesis in mouse myocardial infarction model by producing and releasing miR-132, which has proangiogenic, prosurvival, and antifibrotic activity. To investigate whether their exosomes have a role in their proangiogenic activity, we examined exosomes secreted by these cells. Nanoparticle tracking analysis (NTA) results indicated the presence of exosome size particles in the preparations. Experiments performed with hypoxic (1% O2) human umbilical vein endothelial cells (HUVECs) confirmed that the pericyte exosomes had proangiogenic and anti-apoptotic features. To understand the miRNA cargo of these exosomes that is important in their unique properties, we performed a miRNA array for profiling of 752 miRNAs.

Aberrantly expressed lncRNAs in Primary Varicose Great Saphenous Veins

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.

Microarray analysis of HSVSMC treated with TGF-beta in the presence and absence of small molecule kinase inhibitors

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.

Time-dependent changes of microglial exosomal miRNAs expression signatures following repetitive mild traumatic brain injury

Project description:To acquire the time profiling of miRNA levels in microglial exosomes from injured brain after rmTBI, we employed a developed rmTBI mice model, and harvested the microglial exosomes at 1, 3, 7, 14, 21, 28, 35 and 42 DPI. The exosomes were first identified by TEM scanning, NTA measurement and Western Blot. miRNA microArray was performed to detect the miRNA levels in microglial exosomes after rmTBI. 3, 14 and 42 DPI were selected to respectively represents the time-point of acute phase, sub-acute phase and chronic phase after rmTBI. 10 miRNAs had an expression change of more than two-folds (up- or down-regualted) with a P value less than 0.05 at the 3 time-points. Among them, the expression changes of miR-124-3p were particularly evident. In addition, miR-124-3p was the only miRNA that up-regulated at 3 and 14 DPI, and down-regulated (reversely expressed) at 42 DPI, suggesting that its low expression in the chronic phase after rmTBI may exert a reverse impact on neural pathology, compared with that in the acute and sub-acute phase.

Alteration of mRNA and microRNA expression profiles in rat muscular type vasculature in early postnatal development [miRNA]

Project description:This study tested the hypothesis that miRNA expression profiles change in the muscular type rat saphenous artery during early postnatal development. To explore this, we performed miRNA microarray analysis on muscular type saphenous arteries of young (10-12 days) and adult (2-3 months) rats. For one sample four saphenous arteries from 2 young animals (n = 4 samples per group) or two saphenous arteries from one adult animal (n = 4 samples per group) were used to profile miRNA (n = 8; GeneChip® miRNA 3.0) expression changes during the muscular type rat saphenous artery during early postnatal development. In this study, 10-12 days old (“young”) and 2 - 3 months old (“adult”) male Wistar rats were used.

Exosomes from MSC facilitate diabetic wound healing by promoting angiogenesis

Project description:Mesenchymal stem cell (MSC)-derived exosomes had been reported to be a prospective candidate in accelerating diabetic wound healing. Hence, this study intended to explore whether exosomes originating from the human umbilical cord MSC (hucMSC) could display a superior proangiogenic effect on diabetic wound repair and its underlying molecular mechanism.

Pericardial fluid exosome miRNA profiling

Project description:Pericardial sac surrounding the heart contains pericardial fluid (PF), which is rich in exosomes. PF exosomes increase angiogenesis in hypoxic endothelial cells and in animal model of hindlimb ischemia by passing the proangiogenic miRNAs to recipient cells. However, under pathological conditions such as diabetes, exosome cargo composition changes and harmful miRNAs can be transferred to the recipient cells and induce more deleterious effects in target tissues. In order to check cargo composition of different PF exosomes, we used PF exosomes from non-diabetic aortic valve replacement (AVR), mitral valve replacement (MVR), coronary artery bypass grafting (CABG) patients and CABG patients with diabetes.
