The relative amounts of carddac proteins such as laminin, fibronectin, cytochrome c oxidase, and isomyosin types were studied by gel electrophoresis and Western blotting in control and copper-deficient Sprague-Dawley rats of both sexes fed their respective diets from weanling for 3 weeks. Isomyosin types appeared to shift from V1 to greater levels of V3 in copper deficient rats for both genders. Male copper deficient rats had increased cardiac levels of fibronectin, decreased laminin levels, cardiac hypertrophy and anemia. Both male and female rats fed copper-deficient diet had lower levels of cytochrome c oxidase (CCO) subunit IV, and low liver copper, and high heart-to-body weight ratios compared with their respective controls.
