Circadian differences in behavioral sensitization to cocaine: putative role of arylalkylamine N-acetyltransferase.

Circadian rhythms might be involved in addictive behaviors. The pineal secretory product melatonin decreases cocaine sensitization in rats; mice mutant for the critical melatonin-synthesizing enzyme, arylalkylamine N-acetyltransferase (AANAT), exhibit altered behaviors. We hypothesized that AANAT/melatonin system, which is up-regulated at night, affects cocaine sensitization in mice. Intraperitoneal cocaine treatment (10 and 20 mg/kg) dose-dependently increased locomotor activity of both normal (C3H/HeJ) and AANAT mutant (C57BL/6J) mice; this effect was similar during the day and at night. Injections of cocaine during the day for three days resulted in behavioral sensitization in normal and AANAT mutant mice whereas treatment at night triggered sensitization in AANAT-deficient mice only. AANAT expression and synthesis of N-acetylserotonin/melatonin could play a role in addictive properties of cocaine.[1]
