Article Title: | Blockade of U50,488H analgesia by antisense oligodeoxynucleotides to a κ-opioid receptor |
Abstract: | The recently cloned κ-opioid receptor has binding characteristics consistent with those of a κ1-opioid receptor. Repeated intrathecal administration of an antisense oligodeoxynucleotide against the κ1-opioid receptor selectively lowers U50,488H (trans-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)cyclohexyl]benzeneacetemide) analgesia (P < 0.02) without affecting μ or δ analgesia. A mismatched antisense oligodeoxynucleotide in which 4 bases had been switched is inactive against U50,488H analgesia. These studies confirm at the molecular level traditional pharmacological studies implying a distinct receptor mechanisms for κ1 analgesia and demonstrate the utility of antisense approaches in studies of opioid pharmacology. © 1994. |
