Changes in gene/protein expression markedly outlast the transient changes in behavior evoked by a single dose of a psychostimulant. These changes in gene expression are thought to underlie and/or trigger enduring changes in neuroplasticity that lead to drug addiction. We used cDNA arrays to gain a more complete picture of changes in striatal gene expression 1 and 3 h after an acute injection of amphetamine. Consistent, reliable gene expression changes were detected when criteria of at least a 1.5-fold difference and three replicate hybridizations using independent samples were performed. Using these criteria, the mRNA for three immediate early genes (IEGs), coding for activity-regulated cytoskeletal-associated protein (Arc), nerve growth factor-induced protein A (NGFI-A; early growth response protein 1) and nerve growth factor-induced protein B (NGFI-B), were upregulated 1 and 3 h after amphetamine as previously described. Novel genes, RL/IF-1 (coding for I kappa B alpha chain) and serum/glucocorticoid-regulated serine/threonine protein kinase (SGK) also were increased throughout the striatum, at 1 but not 3 h. Conversely, amphetamine increased the mRNA coding for the secretogranin II precursor (chromogranin C) only at the 3 h time point when a specific decrease in regulator of G-protein signaling 4 (RGS4) mRNA was also observed. Gene changes and unique patterns of expression were verified by in situ hybridization, providing valuable information about changes in gene expression in response to acute amphetamine.
