Abstract

We examined the time-course of expression of c-fos and jun-B mRNAs in the fetal rat suprachiasmatic nuclei (SCN) following maternal cocaine injection on gestational day 20. Both c-fos and jun-B mRNA levels increased within 20 min, peaked at 40 min and declined to baseline by 120 min after cocaine treatment (30 mg/kg). In mice, the D₁-dopamine agonist, SKF 38393, induced c-fos and jun-B mRNAs in the fetal SCN and striatum. Regulated expression of immediate early genes in the fetal SCN may play a role in entrainment of the fetal clock.
