Mucins and O-glycosylation in Health and Disease

Abstract:

Mucins are evolutionarily conserved transmembrane and extracellular matrix molecules that mediate cell communication and signaling events, and also serve as a protective barrier on the external surface of cells.  Many of the unique functional properties of mucins are due to the abundant O-linked glycans present. Defects in mucin-type O-linked glycosylation are responsible for a number of diseases and are also associated with tumor progression and metastasis; HDL-cholesterol and triglyceride levels; congenital defects; and bone mineral density alterations.  Our research investigates the role of this conserved protein modification in normal organ development and function to gain a mechanistic understanding of how alterations in O-glycosylation and mucin biosynthesis contribute to disease susceptibility and progression.
