Our results establish the role of hnRNP K and PCPB1 in the translational control of morphine-induced MOR expression in human neuroblastoma (NMB) cells as well as cells stably expressing MOR (NMB1)..
The human neuroblastoma cell line SK-N-LO and primary dorsal root ganglia (DRG) cells from mice were used to elucidate mediators of μ-opioid receptor signalling.
To investigate the effect of mitragynine after chronic morphine treatment on cyclic AMP (cAMP) level and mRNA expression of mu-opioid receptor (MOR) in human neuroblastoma SK-N-SH cell.
On dissociated neurons and neuroblastoma cells (SH-SY5Y) transfected with NPFF receptors, NPFF acts as a functional antagonist of μ-opioid (MOP) receptors by attenuating the opioid-induced inhibition of calcium conductance.
Prolonged (12h) exposure of SH-SY5Y neuroblastoma cells to the mu-opioid receptor (MOPr) agonist [D-Ala(2),N-Me-Phe(4),Gly(5)-ol]-enkephalin (DAMGO) causes homologous desensitization as well as heterologous desensitization of the extracellular signal-regulated kinase 1/2 (ERK 1/2) phosphorylation induced by insulin-like growth factor (IGF)-I.
Here, we report fluorescence recovery after photobleaching (FRAP) measurements performed at variable spot radius for human mu opioid (hMOP) receptors on SH-SY5Y neuroblastoma cells in the presence of ligands.
Nandrolone treatment (10-10 M) caused a time-dependent and concentration-dependent downregulation of mu opioid receptor (MOPr) transcripts in SH-SY5Y human neuroblastoma cells.
Here, we analyse, by fluorescence recovery after photobleaching measurements, the lateral diffusion of fully functional T7-EGFP-hMOP receptors in neuroblastoma SH-SY5Y cells naturally expressing a low level of the wild-type receptor.
In MOP receptor-overexpressing sc2 cells, short-term morphine exposure was found to be much more potent and efficacious in inhibiting forskolin-elicited production of cAMP, and long-term morphine exposure was shown to induce a substantially higher degree of opiate dependence, as reflected by adenylate cyclase sensitization, than it did in wild-type neuroblastoma cells.
In this report, we demonstrated that interleukin-6 strongly induces mu-opioid receptor mRNA in the human neuroblastoma cell line SH SY5Y, whereas delta-opioid receptor mRNA levels are not influenced.
Mu-opioid receptor (MuOR) and orphanin FQ/nociceptin receptor (ORL(1)) transcripts were measured after activating this pathway in human neuroblastoma cells.
