Aggrecanase degradation of type III collagen is associated with clinical knee pain

There is a lack of biochemical markers for non-invasive and objective assessment of symptomatic osteoarthritis (OA). Aggrecanase activity has been shown to be associated with joint deterioration and symptomatic disease through the degradation of extracellular matrix proteins, such as type III collag…

Characterization of serological neo-epitope biomarkers reflecting collagen remodeling in clinically stable chronic obstructive pulmonary disease

OBJECTIVES:
Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation that leads to excessive remodeling of the lung extracellular matrix (ECM), resulting in release of protein fragments (neo-epitopes) to the blood. Serological markers assessing this have previously been…

Type VIII collagen is elevated in diseases associated with angiogenesis and vascular remodeling

OBJECTIVES:
Type VIII collagen is involved in angiogenesis and remodeling of arteries. We hypothesized that type VIII collagen was upregulated in diseases associated with vascular remodeling, e.g. pulmonary fibrosis and cancer. In this paper we present the development and validation of a competiti…

The development and characterization of an ELISA specifically detecting the active form of cathepsin K

OBJECTIVE:
Cathepsin K plays essential roles in bone resorption and is intensely investigated as a therapeutic target for the treatment of osteoporosis. Hence an assessment of the active form of cathepsin K may provide important biological information in metabolic bone diseases, such as osteoporosi…

MMP mediated type V collagen degradation (C5M) is elevated in ankylosing spondylitis

OBJECTIVES:
Type V collagen has been demonstrated to control fibril formation. The aim of this study was to develop an ELISA capable of detecting a fragment of type V collagen generated by MMP-2/9 and to evaluate the assay as biomarker for ankylosing spondylitis (AS).

DESIGN AND METHODS:
A frag…

Protein fingerprints - relying on and understanding the information of serological protein measurements

In 2004, the FDA has articulated a Critical Path Initiative to improve the efficiency of product development industry-wide, and brought attention to the pressing needs of defining new tools to better assess safety and effectiveness of new products. A better understanding of protein subtypes, protein…

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…

Enzyme-linked immunosorbent assay (ELISAs) for metalloproteinase derived type II collagen neoepitope, CIIM--increased serum CIIM in subjects with severe radiographic osteoarthritis

OBJECTIVES:
In joint degenerative diseases, the collagens are degraded by matrix metalloproteinases and protein fragments are released to serum as potential biomarkers.

METHODS:
A collagen type II specific neoepitope, CIIM, was identified (…RDGAAG(1053)) by mass spectrometry. Two ELISAs against…

Enzyme-linked immunosorbent serum assays (ELISAs) for rat and human N-terminal pro-peptide of collagen type I (PINP)--assessment of corresponding epitopes

OBJECTIVES:
The present study describes two newly developed N-terminal pro-peptides of collagen type I (PINP) competitive enzyme-linked immunosorbent assays (ELISAs) for the assessment of corresponding PINP epitopes in the rat- and human species.

METHODS:
Monoclonal antibodies were raised again…

A novel assay for extracellular matrix remodeling associated with liver fibrosis: An enzyme-linked immunosorbent assay (ELISA) for a MMP-9 proteolytically revealed neo-epitope of type III collagen

OBJECTIVES:
Accumulation of extracellular matrix (ECM) components and increased matrix-metalloprotease (MMPs) activity are hallmarks of fibrosis. We developed an ELISA for quantification of MMP-9 derived collagen type III (CO3) degradation.

DESIGN AND METHODS:
A monoclonal antibody targeting a …

Novel combinations of Post-Translational Modification (PTM) neo-epitopes provide tissue-specific biochemical markers--are they the cause or the consequence of the disease?

The aim of this review is to discuss the potential usefulness of novel advances in the class of biochemical markers, neo-epitopes. Neo-epitopes are post-translational modifications (PTMs) of proteins formed by processes such as protease cleavage, citrullination, nitrosylation, glycosylation and isom…
