Matrix Metalloprotease Generated Fragments of Type VI Collagen Have Serum Biomarker Potential in Cancer - A Proof of Concept Study

BACKGROUND:
Type VI collagen (COL6) is associated with several pro-tumorigenic events. COL6 is primarily composed of three alpha-chains (a1-a3) forming a specialized microfibrillar network to support tissue architecture. COL6 homeostasis is lost in the tumor due to increased COL6 synthesis by activ…

Cancer risk in relation to body fat distribution, evaluated by DXA-scans, in postmenopausal women - the Prospective Epidemiological Risk Factor (PERF) study

Studies with direct measures of body fat distribution are required to explore the association between central and general obesity to cancer risk in postmenopausal women. This study investigates the association between central obesity and general obesity to overall/site-specific cancer risk in postme…

Specific elastin degradation products are associated with poor outcome in the ECLIPSE COPD cohort

Chronic obstructive pulmonary disease (COPD) is characterized by a slow heterogeneous progression. Therefore, improved biomarkers that can accurately identify patients with the highest likelihood of progression and therefore the ability to benefit from a given treatment, are needed. Elastin is an es…

Collagens and Cancer associated fibroblasts in the reactive stroma and its relation to Cancer biology

The extracellular matrix (ECM) plays an important role in cancer progression. It can be divided into the basement membrane (BM) that supports epithelial/endothelial cell behavior and the interstitial matrix (IM) that supports the underlying stromal compartment. The major components of the ECM are th…

Biochemical and histological characterisation of an experimental rodent model of non-alcoholic steatohepatitis - Effects of a peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist and a glucagon-like peptide-1 analogue

BACKGROUND:
Non-alcoholic steatohepatitis (NASH) is a prevalent disease that is highly associated with the metabolic syndrome and type II diabetes. The development of in vivo models that reflect all nuances of the human NASH pathology is essential for drug discovery and development. We aimed to fur…

Association of metabolites reflecting type III and VI collagen formation with modified Rodnan skin score in systemic sclerosis - a cross-sectional study

OBJECTIVE:
The objective was to investigate blood-based biomarkers of type I (PRO-C1), III (PRO-C3) and VI (PRO-C6) collagen formation in systemic sclerosis (SSc) patients and examine their correlation to modified Rodnan skin score (mRSS).

METHODS:
Limited (lSSc, n = 76) and diffuse SSc (dSSc, …

GPDPLQ1237-A Type II Collagen Neo-Epitope Biomarker of Osteoclast- and Inflammation-Derived Cartilage Degradation in vitro

C-telopeptide of type II collagen (CTX-II) has been shown to be a highly relevant biomarker of cartilage degradation in human rheumatic diseases, if measured in synovial fluid or urine. However, serum or plasma CTX-II have not been demonstrated to have any clinical utility to date. Here, we describe…

Combining Naproxen and a Dual Amylin and Calcitonin Receptor Agonist improves pain and structural outcomes in the Collagen-Induced Arthritis rat model

BACKGROUND:
Pain is a debilitating symptom of rheumatoid arthritis (RA), caused by joint inflammation and cartilage and bone destruction. Nonsteroidal anti-inflammatory drugs (NSAIDs) are used to treat pain and inflammation in RA, but are not disease-modifying and do not prevent joint destruction w…

Enhanced processing of von Willebrand factor reflects disease severity and discriminates severe portal hypertension in cirrhosis

OBJECTIVES:
Portal hypertension in cirrhosis is associated with endothelial dysfunction, impaired wound healing, and decreased platelet count. Increased von Willebrand factor (VWF) formation has been suggested as a compensatory mechanism, but the role of VWF processing has not been directly assesse…

Serological Assessment of Activated Fibroblasts by alpha-Smooth Muscle Actin (α-SMA): A Noninvasive Biomarker of Activated Fibroblasts in Lung Disorders

OBJECTIVES:
Remodeling of the extracellular matrix (ECM) is a key event in different lung disorders, such as fibrosis and cancer. The most common cell type in the connective tissue is fibroblasts, which transdifferentiate into myofibroblasts upon activation. All myofibroblasts express α-SMA, which …

Metabolites of C-reactive protein and vimentin are associated with disease activity of axial spondyloarthritis.

OBJECTIVES:
Non-radiographic (nr-axSpA) and radiographic (AS) forms of axial spondyloarthritis (axSpA) share clinical features, but have different radiographic patterns. Radiographic progression is not associated with the current disease activity biomarkers. We investigated a matrix metalloproteina…

Collagen type IV remodelling gender-specifically predicts mortality in decompensated cirrhosis

BACKGROUND & AIMS:
Remodelling of extracellular matrix is crucial in progressive liver fibrosis. Collagen type III desposition has been shown in acute decompensation. Extratracellular matrix is compiled of deposition of various components. The role of basement membrane collagen type IV in advanced …

Molecular taxonomy of osteoarthritis for patient stratification, disease management and drug development

PURPOSE OF REVIEW:
This review focuses on the molecular taxonomy of osteoarthritis from the perspective of molecular biomarkers. We discuss how wet biochemical markers may be used to understand disease pathogenesis and progression and define molecular endotypes of osteoarthritis and how these corre…

Potential diagnostic value of a type X collagen neo-epitope biomarker for knee osteoarthritis.

OBJECTIVE:
Phenotypic changes of chondrocytes toward hypertrophy might be fundamental in the pathogenesis of OA, of which type X collagen (Col10) is a well-known marker. The purpose was to develop a specific immunoassay for blood quantification of a newly identified neo-epitope of type X collagen t…

Vastatin (the NC1 domain of human type VIII collagen a1 chain) is linked to stromal reactivity and elevated in serum from patients with colorectal cancer.

Vastatin, a fragment derived from type VIII collagen, is one of the least studied collagen-derived matrikines. Vastatin can be detected in serum but little is known regarding the relevance of serum vastatin in colorectal cancer (CRC). In this study, serum vastatin was measured (ELISA) in 67 healthy …

The mTORC1/4E-BP1 axis represents a critical signaling node during fibrogenesis.

Myofibroblasts are the key effector cells responsible for excessive extracellular matrix deposition in multiple fibrotic conditions, including idiopathic pulmonary fibrosis (IPF). The PI3K/Akt/mTOR axis has been implicated in fibrosis, with pan-PI3K/mTOR inhibition currently under clinical evaluatio…
