| Research Abstract |
We generated transgenic mice overexpressing a glycosyltransferase, LARGE. The mice were born and grew normally, and laminin binding activity of dystroglycan was greatly increased in the skeletal muscle. We crossed the transgenic mice with dy^<2J> mice, a mouse model of congenital muscular dystrophy, to examin therapeutic effect of LARGE overexpression. The dystrophic change of dy^<2J> mice overexpressing LARGE, however, was not improved and the degeneration of myofibers was rather deteriorated.
