Assessment of extracellular matrix-related biomarkers in patients with lower extremity artery disease

BACKGROUND:
The prevalence of lower extremity artery disease (LEAD) is high (20%-25%) in the population older than 65 years, but patients are seldom identified until the disease is advanced. Circulating markers of disease activity might provide patients with a key opportunity for timely treatment. …

Acute Myocardial Infarction and Pulmonary Diseases Result in Two Different Degradation Profiles of Elastin as Quantified by Two Novel ELISAs

BACKGROUND:
Elastin is a signature protein of the arteries and lungs, thus it was hypothesized that elastin is subject to enzymatic degradation during cardiovascular and pulmonary diseases. The aim was to investigate if different fragments of the same protein entail different information associated…

A MMP derived versican neo-epitope is elevated in plasma from patients with atherosclerotic heart disease

Extracellular matrix remodelling is a prerequisite for plaque rupture in atherosclerotic lesion. Versican, an extracellular matrix proteoglycan present in normal and atherosclerotic arteries is a substrate for matrix metalloproteinases (MMPs) present in macrophage rich areas. The aim of the current …

Atherofibrosis - a unique and common process of the disease pathogenesis of atherosclerosis and fibrosis - lessons for biomarker development

The hallmark of a variety of fibrotic diseases such as liver fibrosis, lung fibrosis, skin fibrosis and atherosclerosis is extensive extracellular matrix remodeling (ECMr) of the disease affected tissue. Inflammation often leads to tissue disruption and destruction, upon which locally released batte…

Novel cardiac-specific biomarkers and the cardiovascular continuum

The concept of the cardiovascular continuum, introduced during the early 1990s, created a holistic view of the chain of events connecting cardiovascular-related risk factors with the progressive development of pathological-related tissue remodelling and ultimately, heart failure and death. Understan…

Tumor necrosis factor-α and receptor activator of nuclear factor-κB ligand augment human macrophage foam-cell destruction of extracellular matrix through protease-mediated processes

By secreting proteases such as cathepsins and matrix metalloproteinases (MMPs), macrophage foam cells may be a major cause of ruptured atherosclerotic plaques. The aims of the present study were to investigate in vitro role of human macrophage foam cells in degrading type I collagen, a major compone…

Development and validation of an enzyme-linked immunosorbent assay for the quantification of a specific MMP-9 mediated degradation fragment of type III collagen--A novel biomarker of atherosclerotic plaque remodeling

Degradation of collagen in the arterial wall by matrix metalloproteinases is the hallmark of atherosclerosis. We have developed an ELISA for the quantification of type III collagen degradation mediated by MMP-9 in urine.

DESIGN AND METHODS:
A monoclonal antibody targeting a specific MMP-9 genera…

Levels of Circulating MMCN-151, a Degradation Product of Mimecan, Reflect Pathological Extracellular Matrix Remodeling in Apolipoprotein E Knockout Mice

AIM:
Arterial extracellular matrix (ECM) remodeling by matrix metalloproteinases (MMPs) is one of the major hallmarks of atherosclerosis. Mimecan, also known as osteoglycin has been implicated in the integrity of the ECM. This study assessed the validity of an enzyme-linked immunosorbent assay (ELI…

Distribution, size, shape, growth potential and extent of abdominal aortic calcified deposits predict mortality in postmenopausal women

Aortic calcification is a major risk factor for death from cardiovascular disease. We investigated the relationship between mortality and the composite markers of number, size, morphology and distribution of calcified plaques in the lumbar aorta.

METHODS:
308 postmenopausal women aged 48-76 were…

Macrophage-mediated proteolytic remodeling of the extracellular matrix in atherosclerosis results in neoepitopes: a potential new class of biochemical markers

Worldwide, cardiovascular disease (CVD) is the leading cause of death. Most CVD-related deaths are caused by years of preceding atherogenesis and the extensive development of atherosclerotic plaques, some of which may rupture to cause myocardial infarction. Macrophages are known to have a role in al…

Human macrophage foam cells degrade atherosclerotic plaques through cathepsin K mediated processes

BACKGROUND:
Proteolytic degradation of Type I Collagen by proteases may play an important role in remodeling of atherosclerotic plaques, contributing to increased risk of plaque rupture.The aim of the current study was to investigate whether human macrophage foam cells degrade the extracellular mat…

Long-term prevention with hormone-replacement therapy after the menopause: which women should be targeted?

For decades, hormone-replacement therapy (HRT) was considered safe and was the first choice in prevention of postmenopausal osteoporosis induced by estrogen deficiency. Numerous experimental and epidemiological studies further supported a protective effect of exogenous female sex hormones on atherog…
