title: Evidence for regulation of vasopressin gene transcription by the NMDA receptor.
abstract: We investigated the effects of dizocilpine maleate (MK-801), an NMDA receptor antagonist, on arginine vasopressin heterogeneous nuclear RNA expression in the supraoptic nucleus in the rat hypothalamus. MK-801 treatment completely blocked the osmotic stimulus-induced increase in AVP hnRNA expression, but had no effect on basal AVP hnRNA expression in the SON. These observations indicate that the NMDA receptor is essential for regulation of AVP gene transcription in response to osmotic stimulation, but has no effect on steady-state AVP gene transcription.
