Favine/CCDC3 deficiency accelerated atherosclerosis and thrombus formation is associated with decreased MEF2C-KLF2 pathway

ABSTRACT: Currently, no mouse models manifest calcification and thrombus formation, which is frequently associated with human atherosclerosis. We demonstrated that lack of Favine/CCDC3 in apoE knockout mice accelerated atherosclerosis accompanied by large cholesterol crystals and calcification, and also promoted thrombus formation in the left ventricle and arteries. Circulating Favine was detectable in WT mouse lasma. RNA-sequencing analysis of aortae in DKO mice showed similar gene expression patterns of human atherosclerosis with unstable and vulnerable plaques. Importantly, human FAVINE mRNA expressions were lower in atheroma plaque than in adjacent intact aortic tissue and decreased with the progression of atherosclerosis. Pathway analysis of aortae in DKO mice suggested the decrease of the MEF2C-KLF2-mediated transcriptional pathway. Favine insufficiency and its attenuated downstream pathways may increase atherosclerosis progression with calcification and thrombus, which have not previously been fully modeled in experimental animals. Favine and its downstream pathways may have therapeutic potential for atherosclerosis.

Multi-platform approach for plaque-derived biomarkers for the vulnerable plaque. Challenges and promises.

Project description:Plaque rupture and subsequent thrombus formation is responsible for the majority of clinical complications of atherosclerosis and nonetheless our understanding of what underlies plaque vulnerability and rupture is still sparse and mostly deductively based on animal models and in vitro studies. We adopted five different -omics platforms to compare ruptured atherosclerotic and advanced-stable tissue within the same carotid plaque specimen from 24 carotid endarterectomy patients. Segments designated as stable feature either a fibrous cap atheroma or pathological intimal thickening. Segments designated as ruptured include a thrombus and/or presented intraplaque hemorrhage. For the present study only those samples were selected for further analysis that were flanked by two segments of identical classification, be it stable (S) or ruptured (R); and were derived from CEA specimen that contained plaque segments of both classifications.

Parton2018 - A model of Atherosclerosis and atheroma formation.

Project description:SBML and SBGN-ML models of atherosclerosis and atheroma formation. This model is described in the publication: New models of atherosclerosis and multi-drug therapeutic interventions. Andrew Parton, Victoria McGilligan, Melody Chemaly, Maurice O’Kane, Steven Watterson Bioinformatics, bty980, https://doi.org/10.1093/bioinformatics/bty980 Motivation. Atherosclerosis is amongst the leading causes of death globally. However, it is challenging to study in vivo or in vitro and no detailed, openly-available computational models exist. Clinical studies hint that pharmaceutical therapy may be possible. Here we develop the first detailed, computational model of atherosclerosis and use it to develop multi-drug therapeutic hypotheses. Results. We assembled a network describing atheroma development from the literature. Maps and mathematical models were produced using the Systems Biology Graphical Notation (SBGN) and Systems Biology Markup Language (SBML), respectively. The model was constrained against clinical and laboratory data. We identified five drugs that together potentially reverse advanced atheroma formation. Availability and Implementation. The map is available in the supplementary information in SBGN-ML format. The model is available in the supplementary material and from BioModels, a repository of SBML models, containing CellDesigner markup.

Coagulation Factor XIII-Binding Aptamers as Bivalent Ligands Targeting Fibrin and Activated Platelets in the Thrombus

Project description:Thromboembolic diseases are commonly associated with thrombus-induced ischemia and tissue damage; identification of the location of the thrombus, or thrombus-targeting, may facilitate diagnosis and target therapy. We hypothesized that aptamers with high affinity and specificity for coagulation factor XIII (FXIII) can serve as thrombus-targeting probes. With systematic evolution of ligands by exponential enrichment technology and semi-activated FXIII (FXIII’) as the target, guanine-rich FXIII’-binding aptamers (FAs; 76 nt) were selected from a library of single-stranded DNA. Next generation sequencing identified FAs with the highest frequency; bio-layer interferometry revealed a dissociation constant (Kd) from 0.7 to 2.5 nM. Truncation with preservation of a conserved region based on entropy analysis resulted in three truncated FAs (FATs; 41-47 nt) that exhibited 4-fold signal in binding to activated vs. resting platelets, as determined by flowcytometry. In addition, FAT2 exhibited up to 4.2-fold binding of that from scrambled ssDNA to platelet/fibrin clot or whole blood clot in vitro, suggesting binding to both activated plateltes and fibrin. FAT2 also exhibited targeting effects in a microcirculatory thrombosis model in mice. Nevertheless, FATs induced no effect on blood coagulation, as determined by thromboelastometry. In conclusion, FXIII-binding aptamers are potentially amenable to thrombus targeting in theranostic application of thromboembolic diseases.

Single cell RNA sequencing of distal thrombus tissue from CTEPH patients

Project description:Our current understanding of CTEPH pathobiology is primarily derived from cell-based studies limited by the use of specific cell markers or phenotypic modulation in cell culture. Therefore, our main objective is to identify the multiple cell types that comprise the CTEPH thrombus and to study their dysfunction. Here we used single cell RNA sequencing (scRNAseq) of tissue removed at the time of pulmonary endarterectomy (PEA) surgery from five patients to identify the multiple cell types. Our scRNAseq identify the multiple cell types including macrophages, T cells, and smooth muscle cells, that comprise CTEPH thrombus. Notably, multiple macrophage subclusters were identified but broadly split into two categories, with the larger group characterized by an upregulation of inflammatory signaling predicted to promote pulmonary vascular remodeling. Both CD4+ and CD8+ T cells were identified and likely contribute to chronic inflammation in CTEPH. Smooth muscle cells were a heterogeneous population, with a cluster of myofibroblasts that express markers of fibrosis and are predicted to arise from other smooth muscle cell clusters based on pseudotime analysis. Lastly, our analysis identified protease-activated receptor 1 (PAR1) as a potential therapeutic target that links thrombosis to chronic PE in CTEPH

Differential gene expression in thrombus-derived white blood cells of patients with acute coronary syndrome

Project description:Inflammatory mechanisms and immune cells are involved in acute coronary syndromes (ACS) and may lead to acute plaque rupture. However, the local expression of the different genes potentially involved is largely unknown. We therefore performed an Affymetrix analysis of genes expressed in white blood cells obtained from an occluding coronary thrombus or peripheral blood of patients with ST-elevation myocardial infarction.

To examine vascular smooth muscle cells (VSMC) under four conditions

Project description:Vascular calcification is a hallmark of atherosclerosis and end-stage renal disease (ESRD). However, the molecular mechanism of vascular calcification is poorly understood. Diabetes mellitus is increasingly recognized as the most important cause for atherosclerosis and ESRD. Emerging evidence supports the concept that vascular calcification resembles the process of osteogenesis, in which the vascular smooth muscle cells (VSMC) undergo osteochondrogenic differentiation. Recently, we have established an in vitro calcification system with primary mouse VSMC. With the use of osteogenic stimuli, we induced trans-differentiation of primary mouse VSMC into bone-like cells. Interestingly stroptozotocin (STZ), O-GlcNAcase inhibitor and a drug that has been used to induce diabetes in mice, was able to induce calcification of VSMC and the expression of the osteogenic transcription factor Runx2, suggesting glycosylation may be involved in regulation of Runx2. We have reported an essential role of Runx2 in oxidative stress-induce VSMC calcification and have recently generated a tissue specific mouse with Runx2 ablation in smooth muscle cells. Therefore, we will use STZ and other relevant reagents in the glucose synthesis/metabolism pathways as stimuli for VSMC calcification to characterize the glycogene profiles during VSMC calcification. Results from VSMC of Runx2 knockout mice will be compared with those from control mice to determine the regulation of calcification-associated glycogenes by Runx2 in response to STZ. These studies will provide foundation for further mechanistic studies and may lead to identification of novel strategies and targets for diabetes-induced vascular calcification. To examine vascular smooth muscle cells (VSMC) under two conditions: 1) wild-type VSMC differentiated into bone-like cells with osteogenic media, 2) wild-type VSMC treated with STZ and osteogenic media
