Abstract

Addition of lead acetate to PC12 pheochromocytoma cells elicits induction of c-fos, an immediate early response gene. Induction of c-fos was concentration- and time-dependent: the lowest concentration of lead acetate tested that induced c-fos was 10 μM; induction was observed after a 30 min incubation and remained high after 90 min. Treatment with lead acetate and cycloheximide superinduced c-fos mRNA. Actinomycin D, an inhibitor of mRNA transcription, decreased the level of c-fos mRNA induced by lead acetate by almost 80%. Cadmium chloride and zinc chloride did not induce c-fos mRNA. Since the c-fos gene encodes a transcription factor, Pb²⁺ has the potential to deregulate the expression of other genes.
