【 摘 要 】

Monoclonal antibodies used to distinguish between dystrophin and utrophin were systematically applied to skeletal muscles containing arteries and veins. Small arteries were found to contain long forms of both utrophin and dystrophin, while small veins contained only long forms of utrophin. In addition, all sizes of vascular smooth muscles were demonstrated to contain another related M r 80 kDa protein (possibly a short utrophin transcript). Regardless of their tissue distributions, we assumed that each of these molecules had distinct properties, i.e. dystrophin with a mechanical function and utrophin with an architectural function. This difference in the roles of dystrophin and utrophin could reduce the efficiency of protection against muscle membrane degeneration when utrophin overexpression is programmed.
