Cycloheximide 146-159 insulin-like growth factor 1 Rattus norvegicus 44-47 1710190-10 1990 Cycloheximide-induced blockade of protein biosynthesis also revealed that the IGF binding activity is subject to measurable turnover thereby suggesting that its accumulation represents the balance struck between synthetic and degradative processes. Cycloheximide 0-13 insulin-like growth factor 1 Rattus norvegicus 78-81
