Abstract

Small leucine rich proteoglycans (SLRPs) are important constituents of extracellular matrix (ECM) and contribute to the production, organization and remodelling of collagen and elastin through complex biological systems. The relative expression and distribution of SLRPs in a variety of different mammalian tissues is poorly characterized. The aim of this study was to map the expression of seven SLRPs (biglycan, versican, prolargin, fibromodulin, osteoglycin, decorin and lumican) in seven tissues (bone, cartilage, cruciate ligament, skin, ventricular myocardium, mitral valve and cornea) in young adult dogs using a combination of quantitative real-time PCR, immunohistochemistry and protein immunoblotting.

Clear and consistent patterns of SLAP expression and distribution were identified for the seven tissues examined, with the greatest SLRP expression in cartilage, skin, cornea and mitral valve, and the least expression in myocardium. In general, lumican and prolargin had the greatest expression across the seven tissues whilst osteoglycin was the least abundantly expressed SLRP. These data provide a SLRP profile for different canine tissues which can inform future studies of SLRP expression in development and disease.
