Cycloheximide blockade of VIP peptide induction with a minimum effect on basal VIP levels in chromaffin cells
VIP peptide content was measured 24 h after the addition of PMA, preceded by treatment with 0.5 μg/ml cycloheximide for 60 min before the addition of PMA. Values are mean ± S.E.M. determined from quadruplicate wells. VIP radioimmunoassay was carried out as described by Lee et al. (1999).
