Outline of Final Research Achievements |
α-Dystroglycan (α-DG) stabilizes plasma membrane by binding with laminin via its glycan chain. Mutations of glycpsyltransferases involved in the glycosylation ofα-DG lead to multi-organ disorders including muscular dystrophy, brain anomaly and eye abnormality, which is called α-dystroglycanopathy. In this study, we conducted basic research to develop glycosyltransferase replacement therapy forα-dystroglycanopathy, which aims to treat the patients by correcting abnormal glycan structure of α-DG with glycpsyltransferases protein. Further, using CRISPR/Cas9 genome editing technology, we established cell culture assay system for the glycosyltransferase replacement therapy, and advocated to use ricin-B subunit as a trafficking tag to the endoplasmic reticurum.
