Molecular taxonomy of osteoarthritis for patient stratification, disease management and drug development: biochemical markers associated with emerging clinical phenotypes and molecular endotypes.

January 1, 2019

Curr Opin Rheumatol

Abstract 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 correspond to clinical phenotypes. RECENT FINDINGS Emerging evidence suggests that osteoarthritis is […]

RAAS inhibitors directly reduce diabetes-induced renal fibrosis via growth factor inhibition.

January 1, 2019

J Physiol

Abstract KEY POINTS Increased activation of the renin-angiotensin-aldosterone system (RAAS) and elevated growth factor production are of crucial importance in the development of renal fibrosis leading to diabetic kidney disease. The aim of this study was to provide evidence for the antifibrotic potential of RAAS inhibitor (RAASi) treatment and to explore the exact mechanism of […]

Assessment of liver fibrosis progression and regression by a serological collagen turnover profile.

January 1, 2019

Am J Physiol Gastrointest Liver Physiol

Abstract There is a need for noninvasive biomarkers that can identify patients with progressive liver fibrosis and monitor response to antifibrotic therapy. An equally important need is identification of patients with spontaneous fibrosis regression, since they may not need treatment nor be included in clinical studies with fibrosis as end point. Circulating biomarkers, originating from […]

A biomarker of collagen type I degradation is associated with cardiovascular events and mortality in patients with atherosclerosis.

January 1, 2019

J Intern Med

Abstract OBJECTIVE Atherosclerosis is characterized by accumulation of lipids, cells and extracellular matrix (ECM) proteins in the arterial wall. Collagen type I (COL1), a component of the arterial ECM, is cleaved by matrix metalloproteinases (MMPs) and known to be remodelled in atherosclerosis. We explored whether the MMP-mediated COL1 biomarker, C1M, was associated with cardiovascular events, […]

Understanding cardiac extracellular matrix remodeling to develop biomarkers of myocardial infarction outcomes.

January 1, 2019

Matrix Biol

Abstract Cardiovascular Disease (CVD) is the most common cause of death in industrialized countries, and myocardial infarction (MI) is a major CVD with significant morbidity and mortality. Following MI, the left ventricle (LV) undergoes a wound healing response to ischemia that results in extracellular matrix (ECM) scar formation to replace necrotic myocytes. While ECM accumulation […]

Changes of patient-reported outcomes and protein fingerprint biomarkers after exercise therapy for axial spondyloarthritis.

January 1, 2019

Clin Rheumatol

Abstract The objective of this study was to investigate the patient-reported outcomes (PROs) and matrix metalloproteinase (MMP) derived extracellular matrix (ECM) biomarkers in non-radiographic (nr)-axial spondyloarthritis (axSpA) and radiographic (r)-axSpA after exercise intervention. Forty-six axSpA patients with stable disease and treatment underwent 24 weeks long exercise intervention. The clinical and laboratory assessments were performed at baseline […]

Recent advances in understanding the phenotypes of osteoarthritis.

January 1, 2019

F1000Res

Abstract Recent research in the field of osteoarthritis (OA) has focused on understanding the underlying molecular and clinical phenotypes of the disease. This narrative review article focuses on recent advances in our understanding of the phenotypes of OA and proposes that the disease represents a diversity of clinical phenotypes that are underpinned by a number […]

A caspase-6-cleaved fragment of Glial Fibrillary Acidic Protein as a potential serological biomarker of CNS injury after cardiac arrest.

January 1, 2019

PLoS One

Abstract Blood levels of Glial Fibrillary Acidic protein (GFAP) reflect processes associated with different types of CNS injury. Evidence suggests that GFAP is cleaved by caspases during CNS injury, hence positioning GFAP fragments as potential biomarkers of injury-associated processes. We set out to develop an assay detecting the neo-epitope generated by caspase-6 cleavage of GFAP […]

Circulating levels of PRO-C3 reflect liver fibrosis and liver function in HIV positive patients receiving modern cART.

January 1, 2019

PLoS One

Abstract BACKGROUND AND AIMS Although combined antiretroviral treatment (cART) has improved overall survival of HIV infected patients, liver fibrosis and liver related-mortality still constitute major challenges in HIV positive patients. Collagen accumulates in the liver during fibrogenesis. Recent studies showed that circulating levels of extracellular matrix (ECM) fragments might reflect degree of portal hypertension and […]

Tissue metabolite of type I collagen, C1M, and CRP predicts structural progression of rheumatoid arthritis.

January 1, 2019

BMC Rheumatol

Abstract BACKGROUND Biomarkers of rheumatoid arthritis (RA) disease activity typically measure inflammation or autoimmunity (e.g. CRP, RF). C1M and C3M, metabolites of type I and III collagen, are markers reflecting tissue metabolism. These markers have been documented to provide additional prognostic and predictive value compared to commonly used biomarkers. We investigated the relationship of high […]
