| Abstract: | In the present experiments the changes in levels of ribosome,polysome and 3H-leucine incorporation rate in liver post-mitochondrial supernatant (PM-supernatant) were investigated in Sedericient and Se-supplented rats.The results demonstrated that the amounts of ribosome and polysome as well as the ratio of polysome to ribosome in liver PM-supernatant from the Se-deficient rats were all remarkahly decreased.In the meantime,the rate of protein synthesis expressed as radioactivity or 3H-leucine incorporated into protein in the PM-supernatant system also decreased significantly.The results suggest that the decreases of ribosomes and proportion of ribosomal aggregates in PM-supernatant may be responsible for the decrease of the protein synthesis activity in liver of the Se-deficient animals. |
