Nociceptin, a heptadecapeptide, is the endogenous ligand of the nociceptin receptor, acting as a potent anti-analgesic.

In Vitro	Nociceptin (1 μg/mL) significantly prevents LPS (10 ng/mL)-stimulated cell migration whereas it is ineffective when added alone. Nociceptin (1 nM-10 μM) elicits a concentration-dependent blockade of LPS-mediated cell migration, with a maximal effect at 1 and 10 μM. Nociceptin counteracts LPS-induced elevation of IL-1β mRNA levels. Nociceptin (1 μM) and NNC 55-0396 induce apoptotic cell death in U87 cells. Nociceptin (1 μM) counteracts LPS-induced [Ca2+]i increase in U87 cells via β-arrestin 2. Nociceptin counteracts the LPS-induced phosphorylation of PKC and ERK in U87 cells. Nociceptin inhibits the LPS-mediated transcriptional activation of NF-kB and AP-1 reporter genes[1].
Cell Assay	Cell proliferation assay is carried out in the assay. U87 cells are plated on 12-well plate and treated for 24 h maintained in cell culture medium containing 10% fetal bovine serum. Five hours before the end of the treatments, [methyl-3H] Thymidine (50 nM final concentration) is added to serum-free cell culture medium and the plate is incubated at 37°C. Thereafter, medium is removed and cells are washed twice with PBS. 200 μL of PBS is added to each well, the cells are scraped off and centrifuged at 13,000g for 3 min at 4°C; supernatants are then discarded, pellets resuspended in 500 μL of cold trichloroacetic acid (10% w/v), incubated on ice for 20 min and centrifuged at 13,000g for 3 min at 4°C. The obtained supernatant is then discarded, pellet suspended in 500 μL of cold methanol and centrifuged at 3 min for 13,000g at 4°C. After that, the pellet is suspended in 200 μL of NaOH 1 N and heated at 55°C for 10 min. Samples are then neutralized with 200 μL of HCl 1 N and 350 μL of the labeled DNA incubated in counting vials with 4 mL of Filter Count scintillation liquid. Vials are vortexed and incubated overnight at room temperature and the radioactivity is determined by liquid scintillation spectrometry.
