Transcription profiling by array of methamphetamine (METH)-treated rats with high or low behavioural responses against saline-treated controls


ABSTRACT: To gain a better understanding of the mechanisms associated with the differences in the individual response to METH and thereby, further develop a list of candidate genes and pathways of possible relevance to human stimulant dependence, mania and psychosis, we conducted the present study. Rats were treated acutely with either METH or saline and their behavior measured for 3 hours after drug administration. METH treated rats were divided into high responders (HR) and low responders (LR) based on their stereotypy response. We compared gene expression between HR and LR and between these two groups and saline control.

Methamphetamine (METH) administration mimics many of the symptoms of mania and can produce psychosis after chronic use. Both rodents and man display interindividual variation in response to METH. The molecular mechanisms underlying these differences might be relevant to both stimulant addiction and endogenous psychosis. We treated 50 Sprague-Dawley rats acutely with METH (4.0 mg/kg) and 10 control rats with saline, and measured their behavior for 3 h after drug administration. Animals were divid  ...[more]
