An important component of the decrease in protein synthesis in muscle of diabetic animals is a fall in the ribosome content. Therefore, we have investigated the turnover of ribosomes in skeletal muscle, heart, and liver of rats during the onset of diabetes. Synthesis rates were measured by incorporation of label into the protein moieties of the ribosomes, and a dual isotope technique was used to relate ribosome synthesis to that of total tissue protein. Degradation rates were calculated as the difference between the rates of synthesis and accumulation. The loss of ribosomes from gastrocnemius muscle and heart took place mainly between the 2nd and 4th days of insulin deficiency and was brought about largely by a very pronounced increase in the degradation rate, though synthesis also fell by a substantial amount. Rates of total tissue protein synthesis decreased markedly, but the degradation rates were only slightly elevated, if at all. Thus, the effect of diabetes on muscle ribosome breakdown was quite distinct from that on degradation of total tissue protein. In liver the response of protein synthesis to diabetes was much less pronounced than in muscle, and ribosome synthesis was not affected.
