Excessive matrix metalloprotease-mediated degradation of interstitial tissue (type I collagen) independently predicts short-term survival in an observational study of postmenopausal women diagnosed with cancer.

August 8, 2017

Oncotarget

Abstract Extensive tissue remodeling mediated by matrix metalloproteases (MMPs) is an important part of cancer. The aim of this study was to investigate whether serum biomarkers reflecting MMP-mediated degradation of type I collagen (C1M), type IV collagen (C4M) and citrullinated vimentin (VICM) were predictive of cancer-specific mortality. Between 1999 and 2001, 5855 Danish postmenopausal women […]

Type I and III collagen turnover is increased in axial spondyloarthritis and psoriatic arthritis. Associations with disease activity and diagnostic capacity.

August 1, 2017

Clin Exp Rheumatol

Abstract OBJECTIVES To investigate the turnover of type I and III collagen by neo-epitope markers in patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). METHODS Patients with PsA (n=101) or axSpA (n=110) and healthy subjects (n=120) were included. Demographic and clinical data were recorded. Markers of type I and III collagen were quantified by […]

Osteoarthritis Cartilage

Abstract The extracellular matrix (ECM) of articular cartilage is comprised of complex networks of proteins and glycoproteins, all of which are expressed by its resident cell, the chondrocyte. Cartilage is a unique tissue given its complexity and ability to resist repeated load and deformation. The mechanisms by which articular cartilage maintains its integrity throughout our […]

The minor collagens in articular cartilage.

August 1, 2017

Protein Cell

Abstract Articular cartilage is a connective tissue consisting of a specialized extracellular matrix (ECM) that dominates the bulk of its wet and dry weight. Type II collagen and aggrecan are the main ECM proteins in cartilage. However, little attention has been paid to less abundant molecular components, especially minor collagens, including type IV, VI, IX, […]

The Dual Amylin- and Calcitonin-Receptor Agonist KBP-042 Works as Adjunct to Metformin on Fasting Hyperglycemia and HbA1c in a Rat Model of Type 2 Diabetes.

July 1, 2017

J Pharmacol Exp Ther

Abstract KBP-042 is a dual amylin and calcitonin receptor agonist that increases glucose tolerance and insulin action and reduces body weight in rat models of obesity and prediabetes. The objective of the present study was to 1) evaluate KBP-042 as a treatment of late-stage type 2 diabetes in a rat model and 2) assess the […]

Misbalance in type III collagen formation/degradation as a novel serological biomarker for penetrating (Montreal B3) Crohn’s disease.

July 1, 2017

Aliment Pharmacol Ther

Abstract BACKGROUND Misbalances in extracellular matrix turnover are key factors in the development of stricturing (Montreal B2) and penetrating (Montreal B3) Crohn’s disease. AIM To determine whether serological markers for collagen formation and degradation could serve as biomarkers for complications of Crohn’s disease. METHODS Serum biomarkers for type I, III, V and VI collagen formation […]

Serological biomarkers detect active joint destruction and inflammation in patients with haemophilic arthropathy.

July 1, 2017

Haemophilia

Abstract INTRODUCTION Progressive arthropathy caused by recurrent joint bleeds is a severe complication in haemophilia. AIM We investigated whether biomarkers of cartilage and bone degradation, and inflammation were altered in haemophilia patients and whether these biomarkers could identify haemophilia patients with arthropathy. METHODS Serum from 35 haemophilia patients with varying degrees of arthropathy and 43 […]

Metabolic Syndrome, Insulin Resistance, and Cognitive Dysfunction: Does Your Metabolic Profile Affect Your Brain?

July 1, 2017

Diabetes

Abstract Dementia and type 2 diabetes are both characterized by long prodromal phases, challenging the study of potential risk factors and their temporal relation. The progressive relation among metabolic syndrome, insulin resistance (IR), and dementia has recently been questioned, wherefore the aim of this study was to assess the potential association among these precursors of […]

Biomarker of extracellular matrix remodelling C1M and proinflammatory cytokine interleukin 6 are related to synovitis and pain in end-stage knee osteoarthritis patients.

July 1, 2017

Pain

Abstract Little is known about local and systemic biomarkers in relation to synovitis and pain in end-stage osteoarthritis (OA) patients. We investigated the associations between the novel extracellular matrix biomarker, C1M, and local and systemic interleukin 6 (IL-6) with synovitis and pain. Serum C1M, plasma, and synovial fluid IL-6 (p-IL-6, sf-IL-6) were measured in 104 […]
