Open Access Abstract Introduction Asporin also known as periodontal ligament-associated protein 1 PLAP1 is a member of the family of small leucine-rich proteoglycan SLRP family. It is present within the cartilage extracellular matrix ECM and is reported to have a genetic association with osteoarthritis. Its D14 allele has recently been found to be associated with lumbar disc degeneration in Asian subjects. There have been no studies however of this gene s normal immunohistochemical localization within the human intervertebral disc or of expression levels in Caucasian individuals with disc degeneration. Methods Studies were approved by our human subjects Institutional Review Board. Methods included immunohistochemical localization of asporin in the disc of humans and the sand rat a small rodent with spontaneous age-related disc degeneration and Affymetrix microarray analysis of asporin gene expression in vivo and in vitro. Results .
