Dinoprostone 18-22 prostaglandin E receptor 1 Rattus norvegicus 82-85 9832416-8 1998 These results suggest that PGE2 inhibits P/Q- and L-type Ca2+ channels of rat melanotrophs via EP1 and EP3 receptors, which are coupled to pertussis toxin-sensitive G proteins, and produces both voltage-sensitive and -insensitive inhibition of Ca2+ channels.
