In ventricular muscle from 30- to 60-day-old Bio 14.6 cardiomyopathic hamsters, dystrophin-associated glycoproteins of 43, 50 and 150 kDa are markedly reduced in abundance. In particular, the 50-kDa glycoprotein is totally deficient in the sareolemma of myopathic ventricular myocytes as revealed by immunofluorescence microscopy. The dystrophin-glycoprotein complex formation is defective in the cardiomyopathic hamster heart, because dystrophin and the glycoproteins behave independently when digitonin-solubilized ventricular homogenates are fractionated on wheat germ agglutinin beads or anti-dystrophin immunoaffinity beads. © 1993.
