Abstract: | Previous work indicates that intrastriatal administration of MK-801 does not completely block D1 agonist-induced gene expression in dopamine-depleted rats. The present study examined the effects of systemic MK-801 on such gene expression. A low dose of MK-801 did not affect induction of c-fos or zif268. A high dose completely blocked induction of c-fos, but only slightly suppressed zif268. The data suggest that NMDA receptor activity may not always be necessary for D1-induced gene expression. |
