Zebrafish Opioid Receptor, kappa 1 (OPRK1) interaction partners

  1. ZFOR3 is a unique model to study kappa opioid receptor functionality

Rabbit Opioid Receptor, kappa 1 (OPRK1) interaction partners

  1. These findings provide evidence that previously demonstrated KOR-mediated reduction in intraocular pressure could be caused, in part, by NO production in both the ciliary body and the trabecular meshwork.

Human Opioid Receptor, kappa 1 (OPRK1) interaction partners

  1. The OPRK1 gene variants showed significant association with susceptibility to opioid dependence among Iranians.

  2. Down-regulation of KOR in HCC (show FAM126A Proteins) tumour tissues has a strong association with poor prognosis and KOR might be a potential tumour suppressor.

  3. In HUVEC cells subjected to artificial hyperlipidemia, selective agonists and antagonists showed that kappa-opioid receptor stimulation normalizes endothelial ultrastructure and function under hyperlipidemic conditions via the PI3K (show PIK3CA Proteins)/Akt (show AKT1 Proteins)/eNOS (show NOS3 Proteins) pathway.

  4. The OPRK1/kappa-opioid receptor pathway was found to be downregulated in lesional skin of psoriasis, correlating positively with itch sensation.

  5. Functional activity of Dynorphin 1-17 and fragments (1-6, 1-7 and 1-9) were screened over a range of concentrations against forskolin stimulated human embryonic kidney 293 (HEK (show EPHA3 Proteins)) cells stably transfected with one of KOP (show SPINT2 Proteins), MOP (show NLN Proteins) or DOP (show COPB2 Proteins)

  6. These results indicate that KOR can form a heterodimer with B2R (show BDKRB2 Proteins) and this leads to increased protein kinase A activity by the CREB (show CREB1 Proteins) signaling pathway, leading to a significant increase in cell proliferation.

  7. that promoter fragments of OPRK1 and OPRM1 (show OPRM1 Proteins) were able to upregulate gene expression with mild cognitive impairment

  8. Heterodimerization of the kappa opioid receptor and neurotensin receptor 1 contributes to a novel beta-arrestin-2 (show ARRB2 Proteins)-signaling pathway.

  9. Hypoxia inducible factor-1alpha (HIF-1alpha (show HIF1A Proteins)) siRNA knocked down the increase of endogenous HIF-1alpha (show HIF1A Proteins) messages and diminished the desferrioxamine (DFO)-induced increase of kappa-opioid receptor (hKOR) expression.

  10. genetic association studies in a population in Denmark: Data suggest that carriers/heterozygotes of the C allele (CC/CT) of OPRK SNP rs6473799 report a 30.4% higher mechanical visceral pain tolerance threshold than non-carriers.

Mouse (Murine) Opioid Receptor, kappa 1 (OPRK1) interaction partners

  1. Suggest that peripheral and central MOR (show OPRM1 Proteins) and central KOR may be involved in the modulation of scratching behaviour in imiquimod-treated mice.

  2. chronic KOR activation increased phosphorylation of NR2B (show GRIN2B Proteins) subunit of NMDA at tyrosine 1472 (pNR2B NMDA) in the hippocampus, but not in the cortex.

  3. Pre- and postsynaptic colocalization of kappa opioid receptor and D2R (show DRD2 Proteins) supports a role for kappa opioid receptor potentiating both the D2R (show DRD2 Proteins) inhibitory autoreceptor function and the inhibitory action of D2R (show DRD2 Proteins) on efferent medium spiny neurons. Kappa opioid receptor co-activation accelerates D2R (show DRD2 Proteins) sensitization by contributing to decrease dopamine release in the nucleus accumbens.

  4. Mechanical allodynia produced by monosodium iodoacetate (MIA (show MIA Proteins)) was enhanced in mice lacking KOR or PDYN (show PDYN Proteins) gene. In contrast with the nociceptive manifestations induced by osteoarthritis, the increased microglial expression on the lumbar section of the spinal cord after MIA (show MIA Proteins) administration was similar in KOR-KO, PDYN (show PDYN Proteins)-KO and WT littermates. Moreover, anhedonic- and anxiolytic-like states were revealed after MIA (show MIA Proteins) administration.

  5. The kappa opioid receptor was identified as a key player mediating the effects of buprenorphine in tests sensitive to antidepressant drugs in mice.

  6. This study provides the first evidence for a time- and learning-dependent property of neocortical kappa opioid receptor in facilitating acquisition and consolidation of associative memories.

  7. triazole 1.1 retained the antinociceptive and antipruritic efficacies of a conventional KOR agonist, yet it did not induce sedation or reductions in dopamine release in mice, nor did it produce dysphoria as determined by intracranial self-stimulation

  8. This study reports a cluster of compounds that are highly effective in enhancing remyelination and identifies kappa-opioid receptor (KOR) as a positive regulator for oligodendroglial differentiation, implicating KOR agonism as a potential strategy to accelerate remyelination.

  9. GRK2 (show ADRBK1 Proteins) upregulation causes kappa-opioid receptor desensitization in diabetic heart

  10. Study showed that Dyn (show PDYN Proteins)-A, the endogenous kappa opioid receptor agonist, significantly hyperpolarized and inhibited neurons in the paraventricular nucleus of mouse thalamus
