Check if the same lab product or an alternative is used in the 5 most similar protocols
PGE2, purchased from Sigma (St. Louis, MO, USA) was dissolved in dimethyl sulfoxide (Sigma) and then diluted with complete medium to concentrations suitable for use in this experiment. The receptor agonists and antagonists, obtained from Cayman Chemical (Ann Arbor, MI) were as follows: EP1 receptor and EP3 receptor agonist (Sulprostone, 10 nM), EP2-receptor agonist (Butaprost, 10 µM), EP4 receptor agonist (CAY10580, 10 µM), EP2 receptor antagonist (AH6809, 10 µM) and the EP4 receptor antagonist (AH23848, 10 µM). Akt inhibitor (LY294002, 10 µM) was purchased from Calbiochem (Billerica, MA, USA). NF-κB inhibitor (BAY-11, 1 µM) was bought from Sigma. NPDFs were previously exposed to PGE2 (20 µM) after pre-treatment for 1 hour with all agonists, antagonists and inhibitors.

The mPGES-1 inhibitor compound III (C3) (5 μM) [11 (link)] was synthesized by NovaSAID AB (Solna, Sweden). Celecoxib (5 μM), lipopolysaccharide (LPS) (50 ng/ml), dimethylsulfoxide (DMSO), and rolipram (10 μM) were purchased from Sigma-Aldrich (St.Louis, MO, USA). CD80 (5 μg/ml) and CD86 (5 μg/ml) neutralizing antibodies and the isotype control (5 μg/ml) were purchased from eBiosciences (Frankfurt, Germany) or R&D Systems (Minneapolis, MN, USA). PGE2, butaprost (5 μM), sulprostone (5 μM) and cay10580 (200 nM) were from Cayman Chemicals (Ann Arbor, MI, USA). Both human and murine interferon-γ (IFN-γ) (100 U/ml) were from Peprotech (Hamburg, Germany). Anti-CD3/anti-CD28 Dynabeads (1:20 - bead: PBMCs) were from Invitrogen (Carlsbad, Germany).

Induction of AQP2 expression in mpkCCD cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Mouse mpkCCDc14 cells were maintained essentially as described (Hasler et al., 2002 (link)). Cells were seeded at a density of 1.5 × 105 cells/cm2 on semipermeable filters (Transwell®, 0.4 μm pore size, Corning Costar, Cambridge, MA) and cultured for 8 days. Unless stated otherwise, the cells were exposed to 1 nM of the V2R agonist desmopressin (dDAVP) at the basolateral side during the last 96 h, to maximally induce the AQP2 expression (Li et al., 2006 (link)). Cells were incubated with 10 μM indomethacin, 1 μM PGE2 (both Sigma, St. Louis, MO, USA), 1 μM PGF (Calbiochem, San Diego, CA), 300 nM of EP1/EP3 agonists sulprostone (Sigma, St. Louis, MO, USA), 1 μM of EP4 agonists CAY10580, 0.5 μM of EP4 antagonist Gw627368, 2.5 nM of the EP4 antagonist L161982, 20 μM of EP1 antagonist Sc-51089, or 100 nM of EP1 antagonist Ono-8711 (all Cayman Chemical, Ann Arbor, Michigan, USA) during the last 48 h. The medium was replaced after 24 h, or in experiments using the EP agonists or antagonists, the medium was replaced every 12 h.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
