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

ABSTRACT: This study tested the hypothesis that mRNA expression profiles change in the muscular type rat saphenous artery during early postnatal development. To explore this, we performed mRNA 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 mRNA (n = 8; GeneChip® Rat Gene 1.0) 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.

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.

Transcriptional profiling from young, old, healthy, or injured rat iliac arteries.

Project description:Transcriptional profiling from young, old, healthy, or injured rat iliac arteries. We studied the gene expression profile in a model of mechanical vascular injury in the iliac artery of aging (22 months old) and young rats (4 months old). We investigated aging-related variations in gene expression at 30 min, 3d and 7d post injury.

Gene expression in a resistance artery in 2 models of hypertension in the rat

Project description:We investigated morphometric structure and gene expression by microarray analysis in a small diameter artery, branch of the saphenous artery (a resistance artery), in representative models of renin-angiotensin system (RAS)-dependent and glucocorticoid hypertension, using the spontaneously hypertensive rat (SHR) and adrenocorticotropic hormone (ACTH)-induced hypertensive rat, respectively. Sixteen-week-old male Wistar-Kyoto (WKY) and age-matched spontaneously hypertensive rats (SHR) were used. Keywords: Comparison of global gene expression in resistance arteries of normotensive and genetically hypertensive rats and ACTH-treated rats.

Unique gene program of rat mesenteric arteries as revealed by Deep RNA Sequencing

Project description:This study used Deep RNA sequencing to define gene expression in the small resistance arteries and compare to a reference conduit artery, the aorta Methods: Deep RNA Sequencing (~90 million reads) was performed on 2 samples of adult SD rat mesenteric arteries and compared to that of 2 samples of aorta. Results: ~900 genes were identified that were expressed at least 2-fold difference between meseteric artery and aorta mRNA profiles of 2 samples of rat mesenteric artery and 2 samples of rat aorta were sequenced using Illumina HiSeq

Proteomic profiling of tissue-engineered, small-diameter vascular grafts implanted into the ovine carotid artery

Project description:Albeit vascular prostheses for the replacement of large arteries (e.g. aorta) are commercially available for decades, small-diameter vascular grafts (e.g., for coronary artery bypass graft surgery) still remain an unmet clinical need. Biostable polymers commonly used for the fabrication of aortic prostheses (e.g., poly(ethylene terephthalate) or expanded poly(tetrafluoroethylene)) have insufficient haemocompatibility to withstand thrombosis at low blood flow characteristic of small arteries (e.g., coronary artery). Hence, researchers endeavor to develop a biodegradable, tissue-engineered vascular graft (TEVG) to avoid the use of autologous blood vessels, such as saphenous vein or internal mammary artery, as conduits during the bypass surgery. Although a number of promising prototypes have been designed to date, none of them passed the pre-clinical trials successfully. Implantation into the ovine or porcine arteries is associated with thrombosis, neointimal hyperplasia, and aneurysms within one-year postoperation, precluding further clinical translation of TEVGs. Among the reasons of such impediment is that pathophysiology of TEVG implantation remains unclear and the molecular events occurring in the TEVG upon its implantation have not been properly investigated hitherto. Here, we for the first time performed a proteomic profiling of the TEVGs (n = 12) implanted into the ovine carotid arteries for one year and suffered from thrombosis to identify the signatures of TEVG failure in an unbiased manner. Contralateral intact ovine carotid arteries (n = 12) have been selected as a control group.

A comparison of genome-wide DNA methylation patterns between different tissues from patients with coronary heart disease

Project description:Using the Illumina Infinium Human Methylation27 BeadChip, we performed a genome-wide analysis of DNA methylation in right coronary artery in the area of advanced atherosclerotic plaques, atherosclerotic-resistant internal mammary arteries, and great saphenous veins obtained from same patients with coronary heart disease. The resulting DNA methylation patterns were markedly different between all the vascular tissues. The genes hypomethylated in athero-prone arteries to compare with atherosclerotic-resistant arteries were predominately involved in regulation of inflammation and immune processes, as well as development. The great saphenous veins exhibited an increase of the DNA methylation age in comparison to the internal mammary arteries. Gene ontology analysis for genes harboring hypermethylated CpG-sites in veins revealed the enrichment for biological processes associated with the development. Four CpG-sites located within the MIR10B gene sequence and about 1 Kb upstream of the HOXD4 gene were also confirmed as hypomethylated in the independent dataset of right coronary arteries in the area of advanced atherosclerotic plaques in comparison with the other vascular tissues. Bisulfite converted genomic DNA from 24 samples was denatured, whole-genome amplified, fragmented and subsequently hybridized to the Illumina Infinium 27k Human Methylation Beadchip.
