Research Abstract

Glycosphingolipids (GSLs) are ubiquitous membrane components that modulate transmembrane signaling and mediate cell-to-cell and cell-to-matrix interactions. The purpose of this study was to clarify the functional roles of GSLs in maintaining osteochondral homeostasis using different strains of GSLs synthase knockout (KO) mice. Although all strains of KO mice developed and grew normally, osteoarthritic changes were dramatically enhanced with aging. IL-1 stimulation of chondrocytes from KO mice significantly increased MMP-13 mRNA expression and apoptosis. In addition, KO mice delayed enchondral ossification during fracture repair process. These findings indicate that GSLs have a chondro-/osteo- protective role and prevent disease progression, although GSLs are not essential for osteochondral tissue development in young mice.
