title: Inhibition of liver protein degradation in vivo by intensive treatment with cycloheximide.
abstract: The AA in experiments performed on male rats treated with 0,5 mCi/kg of cycloheximide have observed an inhibition of liver protein degradation and have suggested two mechanism: 1) cycloheximide prevents the acute proteolytic response induced in fibroblast culture by exposure to serum-deficient media and in rat livers after perfusion probably by inhibiting the lysosomal - autophagic system, without modifications in total activity of lysosome proteinases. 2) It may be that protein degradation rate and level of lysosomal proteinases reinterrelated; the latter probably being a factor controlling the overall cell protein turnover rate.
