MK-801 attenuates cocaine induction of c-fos and preprodynorphin mRNA levels in Fischer rats. Academic Article uri icon

Overview

abstract

  • This study shows that single (15 mg/kg) or binge (3x15 mg/kg) cocaine administration increases c-fos mRNA levels, but only binge cocaine administration increases preprodynorphin mRNA levels in the caudate/putamen of Fischer rats. This increase in both c-fos and preprodynorphin mRNA levels is attenuated by the noncompetitive NMDA antagonist MK-801 (0.25 mg/kg), suggesting a preferential role for NMDA receptor co-activation in cellular events leading to cocaine-induced behaviors.
