Calcium activated neutral proteases (milli- and micro-CANP) and endogenous CANP inhibitor of muscle in Duchenne muscular dystrophy (DMD).
Calcium activated neutral protease (milli- and micro-forms) and its endogenous inhibitor have been quantified in muscle from Duchenne muscular dystrophy (DMD) patients. The specific activities of both the enzymes are found to be significantly elevated. Some of the properties studied indicate that the enzymes from DMD and normal are not qualitatively different. The ratios of milli- to micro-enzyme in normal and disease state suggest that these enzymes have independent roles to play. The absence of a significant increase in the level of the endogenous inhibitor is probably indicative of its mode of regulation, in disease condition.
