Terminal glycosylation and disease: influence on cancer and cystic fibrosis.
Terminal glycosylation has been a recurring theme of the laboratory. In cystic fibrosis (CF), decreased sialic acid and increased fucosyl residues in alpha1,3 position to antennary N-acetyl glucosamine is the CF glycosylation phenotype. The glycosylation phenotype is reversed by transfection of CF airway cells with wtCFTR. In neuronal cells, polymers of alpha2,8sialyl residues are prominent in oligodendrocytes and human neuroblastoma. These findings are discussed in relationship to early studies in our laboratories and those of other investigators. The potential extension of these concepts to future clinical therapeutics is presented.
