12672796-2	2003	Endogenous human delta-opioid receptors (hDOR) are differentially regulated in terms of desensitization by peptide ([d-Pen2,5]enkephalin (DPDPE) and Deltorphin I) and alkaloid (etorphine) agonists in the neuroblastoma cell line SK-N-BE (Allouche, S., Roussel, M., Marie, N., and Jauzac, P. (1999) Eur.	Alkaloids	167-175	tumor protein p53 inducible nuclear protein 2	Homo sapiens	41-45	
22101011-1	2012	We have previously reported on the differential regulation of the human delta-opioid receptor (hDOR) by alkaloid (etorphine) and peptidic (DPDPE and deltorphin I) ligands, in terms of both receptor desensitization and post-endocytic sorting.
