Sst1, sst3, sst5 receptors were found exclusively in NCI-H727 and KRJ-I cell lines (1A, 1C, 1D), sst2 were present in all cell lines (1B). D1, D2, D4 and D5 receptors were present in NCI-H727 cells (1E, 1F) while inhibitory D2 and D4 receptors were identified in NCI-H720 (1G). D5 receptors were observed in KRJ-I cells (1H). All sst and D receptors were identified in brain tissue (positive control). Mean±SEM; n=3.
