Post-translational Modifications in Cartilage Oligomeric Matrix Protein

Cartilage oligomeric matrix protein in systemic sclerosis.

Post-translational modifications of protein biopharmaceuticals.

The majority of therapeutic proteins display one or more post-translational modifications (PTMs). These modifications normally influence the biochemical and therapeutic properties of such proteins. Choosing an expression system capable of generating an appropriate product PTM profile remains one of the most crucial decisions a drug developer must make. This review considers the PTMs most often ...

Cartilage oligomeric matrix protein-induced complement activation in systemic sclerosis

INTRODUCTION Complexes between cartilage oligomeric matrix protein (COMP) and the complement activation product C3b have been found in the circulation of patients with rheumatoid arthritis and systemic lupus erythematosus. In systemic sclerosis (SSc) COMP expression in the skin is upregulated both in lesional and non-lesional skin, which is also reflected in an increased amount of circulating C...

Cartilage Oligomeric Matrix Protein in Idiopathic Pulmonary Fibrosis

Idiopathic pulmonary fibrosis (IPF) is a progressive and life threatening disease with median survival of 2.5-3 years. The IPF lung is characterized by abnormal lung remodeling, epithelial cell hyperplasia, myofibroblast foci formation, and extracellular matrix deposition. Analysis of gene expression microarray data revealed that cartilage oligomeric matrix protein (COMP), a non-collagenous ext...

Circulating cartilage oligomeric matrix protein in juvenile idiopathic arthritis.

OBJECTIVES Raised serum cartilage oligomeric matrix protein (sCOMP) has been reported to predict erosive disease in early rheumatoid arthritis (RA). In juvenile idiopathic arthritis (JIA), subnormal sCOMP levels have been associated with ongoing inflammation and growth retardation. In this study we aimed to assess sCOMP, C-reactive protein (CRP), and insulin-like growth factor (IGF)-1 in childr...
