[Stimulation of nuclear membrane components and DNA biosynthesis in rat liver cells after inhibition of translation with cycloheximide].

After a drastic inhibition of protein synthesis (95%) in rat liver by cycloheximide (0.2-0.4 mg/100 g of body weight) the recovery and subsequently prolonged marked stimulation of proteins, lipids and DNA were found. The correlation of nuclear membrane proteins and lipids synthesis was observed in a recovery and stimulation phases. Nuclear DNA synthesis increases after the stimulation biosynthesis of nuclear membrane components (36-40 hours after cycloheximide injection). The changes of a phospholipid composition and structure organisation of nuclear membrane hydrophobic zones (by spin probe) were found in stimulated DNA synthesis (48-60 hours).
