abstract：:Previously, we showed that the human kappa-opioid receptor (hkor) stably expressed in Chinese hamster ovary (CHO) cells underwent down-regulation after prolonged U50,488H treatment. In the present study, we determined the mechanisms underlying this process. U50, 488H caused a significant down-regulation of the hkor, a...
