High salt intake exacerbates aortic dissection through IL-17 pathway

Project description:Rationale— Aortic dissection (AD) is a fatal disease that occurs suddenly without preceding clinical signs or symptoms. It is desirable to prevent AD before the onset. Although high salt intake is an established risk factor for cardiovascular diseases, the relationship between high salt intake and AD has not been clarified. Although recent studies have shown that high salt intake promotes interleukin (IL)-17-dependent inflammation, it is unknown whether this mechanism is involved in the pathogenesis of AD. Objective— The purpose of this study was to investigate the effect of high salt challenge on AD and involvement of IL-17. Methods and Results— We used a mouse AD model that was induced by continuous infusion of -aminopropionitrile and angiotensin II. High salt challenge exacerbated AD lesion length compared to the mice without high salt challenge, which was abolished in IL-17 knockout mice. Unexpectedly, deletion of IL-17 resulted in the activation of Smad pathway, induction of synthetic phenotype of smooth muscle cells, remodeling of extracellular matrix in aortic tunica media, reduced stiffness of aortic walls, and less stress-induced activation of NFkB. Conclusions— These findings establish the worsening effect of high salt intake on AD that involves IL-17 pathway through the extracellular matrix metabolism. Salt restriction may represent a low-cost and practical way to reduce AD risk.

Expression data from control, aortic aneurysm, and aortic dissection cells

Project description:Aneurysmatic and dissection cells show a specific alteration of gene expression, which allow a disease specific distinction. We used microarrays to analyse the cellular gene expression of controls, thoracic aortic aneurysm, and aortic dissection.

Epigenome analysis of ascending aorta from normal, aortic dissection and bicuspid aortic valve patients

Project description:Genome wide DNA methylation profiling of ascending aorta tissue samples from normal, aortic dissection and bicuspid aortic valve patients with aortic dilation. The Illumina Infinium 450k Human DNA methylation Beadchip was used to obtain DNA methylation profiles across more than 450,000 CpGs in ascending aorta samples. Samples included 6 normal donors, 12 patients with aortic dissection and 6 patients with bicuspid aortic valve and dilated aorta.

Expression data from aortic dissection patients and the healthy controls

Project description:The mechanisms of acute aortic dissection are not well understood. Transcriptomic strategy has been proven to be an effective way to find the potential mechanisms and also the reliable biomarkers for a specific disease. The whole-genome expression profiling was assayed in a panel of aortic tissues from 4 male acute aortic dissection patients and 4 male healthy controls.

Exaggerated autophagy as molecular characterization of Stanford type A aortic dissection: A transcriptome analysis of human ascending aortic tissues

Project description:Purpose: The aim of this study is to have a fullscape of molecular pathology of Stanford type A aortic dissection Methods: All TAAD patients under consideration underwent an ascending aortic replacement surgery during a cardiopulmonary bypass. The normal ascending aortic tissue samples were obtained from patients undergoing coronary artery bypass grafting surgery (CABG) without any aortic diseases. We selected 20 samples (10 TAAD and 10 normal) for the whole transcriptome sequencing. Total RNA was extracted from each sample using TRIzol Reagent (ThermoFisher) and was stored in 1 mL of 75% ethanol at -80 ℃ until further usage. Conclusions: We identified exaggerated autophagy as a molecular biomarker for aortic dissection. We also predicted 10 hub genes and an HIF1A-ATG3 axis which could provide new insights in understanding aortic dissection.

17 -estradiol impedes aortic root dilation and rupture in male Marfan mice

Project description:Thoracic aortic aneurysms have a higher prevalence in male patients compared to female patients. Marfan syndrome causes a hereditary form of TAA with dilation of the aortic root. Male patients with Marfan syndrome are more likely than women to have aortic dilation and dissection and mouse models of Marfan syndrome demonstrate larger aortic roots in males compared to females even after adjustment for body size. Similar sex disparities are present in patients and models of abdominal aortic aneurysms where estrogen has been demonstrated to attenuate aneurysm formation perhaps through anti-inflammatory mechanisms. In this study we demonstrate the effects of estrogen on aortic dilation and rupture in a Marfan mouse model and we investigate if these effects operate through suppression of complement components of the immune system.

Circulating microRNAs: a novel potential biomarker for diagnosing acute aortic dissection

Project description:Microarrays with 1,205 human microRNAs and 142 viral microRNAs were used for screening candidate diagnostic markers in the 3 categories of subjects from 24 plasma samples including acute aortic dissection, healthy and aortic aneurysm subjects. There were two microRNAs overlapping in the 3 group comparisons. Finally, 16 candidate microRNAs discovered via microarrays were selected for the further validation.
