RECK-Mediated Suppression of Tumor Cell Invasion Is Regulated by Glycosylation in Human Tumor Cell Lines

Abstract excerpt

RECK, a glycosylphosphatidylinositol (GPI)-anchored glycoprotein, negatively regulates matrix metalloproteinases (MMP), such as MMP-9, and inhibits tumor invasion and metastasis. The predicted amino acid sequence of human RECK includes five putative N-glycosylation sites; however, the precise biochemical role of glycosylated RECK remains unknown. In this study, we examined the link between glycosylation and the...
