The Role of CDCP1 in Carotid Artery Stenosis: Implications for Mitochondrial Autophagy and Therapeutic Potential of 8-isopentenylnaringenin

ABSTRACT: Carotid artery stenosis (CAS) is a major cause of cardiovascular diseases, such as myocardial infarction and stroke. Mitochondrial dysfunction can trigger the onset of these conditions. CUB Domain Containing Protein 1 (CDCP1) is a transmembrane protein that has been demonstrated to contribute to various tumors and myocardial infarction; however, its role in carotid artery stenosis has not yet been reported. In this study, we investigated how CDCP1 affects cellular activity by regulating mitochondrial autophagy, and we propose that 8-isopentenylnaringenin (8-PN) may promote autophagy and alleviate carotid artery stenosis by reducing the expression of CDCP1. CDCP1 is upregulated in vascular smooth muscle cells within a carotid artery stenosis model, as demonstrated by studies conducted both in vivo and in vitro. Knocking down CDCP1 enhanced mitochondrial autophagy by upregulating ATG4A, leading to a reduction in reactive oxygen species (ROS) release and protection of cell viability. Moreover, both in vitro and in vivo experiments confirmed that 8-PN effectively decreases CDCP1 expression, activates cellular autophagy, and mitigates the progression of carotid artery stenosis. These findings highlight the importance ofCDCP1 in carotid artery stenosis and underscore the capability as a therapeutic option for this condition.

Transcription profiling of stroke-susceptible and asymptomatic human carotid plaques

Project description:A microarray analysis of advanced human atherosclerotic carotid artery plaques (equal or over 70% stenosis, NASCET criteria) from radiologically confirmed ipsilateral stroke patients (stroke-susceptible plaques, n=12) compared with carotid plaques collected from clinically asymptomatic patients with clear brain imaging (asymptomatic plaques, n=9) with equivalent conventional risk factors and severity of carotid stenosis.

The effects of Mycophenolate treatment on the transcriptomes of patients with symptomatic carotid artery stenosis

Project description:This study was conducted in order to assess the effects of the compound Mycophenolate mofetil (MMF), an inhibitor of the enzyme inosine monophosphate dehydroxygenase (IMPDH) with a strong cytostatic effect on T-cells, on the phenotype of human carotid artery stenosis in humans in vivo. This was done at the transcriptome level by comparing the gene expression profiles of carotid endarterectomy samples from patients with carotid artery stenosis (>70% diameter stenosis on angiography) that were randomly assigned to treatment with MMF 1000 mg (N=9) or Placebo (N=11), respectively. MMF or placebo was given for at least 2 weeks prior to undergoing carotid endarterectomy (CEA).

Role of CDCP1 and Cardiac Fibrosis in a Mouse Model of Dilated Cardiomyopathy (DCM)

Project description:Cardiac fibrosis is a common pathological feature of various cardiac diseases that contributes significantly to heart failure progression and poor clinical outcomes. Recent genetic studies have shown that lower expression of CUB domain-containing protein 1 (CDCP1) is linked to myocardial recovery, but its direct role in cardiac pathophysiology remains unkown. In this study, we investigated the functional contribution of CDCP1 to pressure overload-induced cardiac remodeling and fibrosis. CDCP1 deletion attenuated Ang II/PE-induced cardiac dysfunction as demonstrated by reduced left ventricular mass index and improved cardiac function compared to wild-type controls. Histological analysis revealed significantly decreased cardiac fibrosis in CDCP1-KO mice. Transcriptomic profiling revealed that CDCP1 KO attenuates cardiac fibrosis through downregulation of matrix metalloproteases, collagen biosynthesis and limiting the pathological remodeling extracellular matrix. Spatial transcriptomics further revealed region-specific alterations in fibrotic and inflammatory signatures among the subtypes of cardiomyocytes and fibroblasts, suggesting localized CDCP1-dependent effects on cardiac remodeling. Our findings establish CDCP1 as a critical regulator of pressure overload-induced cardiac fibrosis and dysfunction. Our work provides direct evidence supporting CDCP1 inhibition as a potential therapeutic strategy for cardiac fibrosis.

Next Generation Sequencing of Asymptomatic and Symptomatic Carotid Atherosclerotic Plaques

Project description:Atherosclerotic plaque rupture is the etiology of ischemic stroke and myocardial infarction. Ribosome-depleted total RNA was sequenced from carotid plaques obtained from patients undergoing carotid endarterectomy with high-grade stenosis and either 1) a carotid-related ischemic cerebrovascular event within the previous 5 days ('recently ruptured,' n=6) or 2) an absence of a cerebrovascular event ('asymptomatic,' n=5). Examination of the differentially expressed genes supported the importance of inflammation and inhibition of proliferation and migration coupled with an increase in apoptosis. Thus, the transcriptome of recently ruptured plaques is enriched with transcripts associated with inflammation and fibrous cap thinning and support further examination of the role of B lymphocytes and interferons in atherosclerotic plaque rupture.

Single-cell transcriptome of the murine carotid artery following acute injury

Project description:Acute vascular injury is an unwelcome consequence of invasive treatments designed to alleviate symptoms of vascular stenosis. Resulting fibrotic scarring and neointima formation may result in loss of lumen diameter and diminished vascular function. Understanding of the key phases of acute inflammation, resolution and remodeling has the potential to minimise unwanted effects on the vasculature and therefore improve patient outcomes. The cellular landscape of blood vessels is highly hetergeneous in nature, and therefore data at single-cell resolution is of high relevance to this problem. Herein, the cellularity of murine carotid artery tissue is described in a cell- and time-resolved manner. Single-cell RNA-sequencing of carotid tissue isolated at time-points ranging from uninjured vessel to 14 days post-injury enabled the recapitulation of all stages of vascular injury. In these data, a sub-population of smooth muscle cells which also arises in atherosclerosis and myocardial infarction was identified. So-called stem cells/endothelial cells/monocytes (SEM) cells are candidates for repopulating injured vessels, and were amongst the most proliferative cell clusters following wire-injury of the carotid artery. Transcriptional signatures reflecting SEM gene expression patterns could also be detected in bulk RNA-sequencing of neointimal tissue isolated by laser capture microdissection. These data indicate that phenotypic plasticity of smooth muscle cells is highly important to the progression of lumen loss following acute vascular insult.

The Stockholm Atherosclerosis Gene Expression (STAGE) study: Global Gene Expression data from coronary and carotid artery disease patients

Project description:Tissue samples have been isolated during corornary artery by-pass grafting (CABG)surgery from the atheroscelrotic arterial wall (AAW, aortic root puncture for proxmal ligation of by-pass vessel), non-atherosclertoci arterial wall (NAAW, distal part of mammary artery used a graft for LAD), liver, skeletal muscle (Recturs m), pericardial mediastinal visceral fat) in CAD patients. Carotid lesions samples from 25 validation patients. We used microarrays to measure global gene expression in these tissues to cluster groups of functionally associated genes and then, second step clustering of patients within each cluster to link clusters to patient phenotypes primarily coronary stenosis (CAD) and Intima media thickness (IMT) in carotid stenosis patients. . All samples were taken during surgery. The time of operation was less than 3 hours in most instances. Sammon plots show strong clustering of tissue-specific arrays. Even separating AAW from NAAW and carotid lesions.
