Figure 1. PGD2-induced concentration-dependent stimulation of intracellular calcium mobilization in CHO-K1/DP1/Gα15 cells. The cells were loaded with Calcium-4 prior to stimulation with a DP1 receptor agonist, PGD2. The intracellular calcium change was measured by FLIPR. The relative fluorescent units (RFU) were normalized and plotted against the log of the cumulative doses (5-fold dilution) of PGD2 (Mean ± SD, n = 2). The EC₅₀ of PGD2 on this cell was 18.5 nM.
Notes:
1. EC₅₀ value is calculated with four parameter logistic equation:
Y=Bottom + (Top-Bottom)/ (1+10^ ((LogEC₅₀-X)*HillSlope))
X is the logarithm of concentration. Y is the response
Y is RFU and starts at Bottom and goes to Top with a sigmoid shape.
2. Signal to background Ratio (S/B) = Top/Bottom

CHO-K1/DP1/Gα15 Stable Cell Line

DP1 is a Gs-coupled GPCR expressed in the colon, eye, platelets, eosinophils, that bind to PGD2 and PGE2. DP1 can inhibit platelet aggregation, and also inhibit leukotriene B4 and superoxide anion (O2-) release from human neutrophils. It can relax smooth muscle and regulate eosinophil apoptosis. DP receptor knockout OVA-challenged mice exhibit reduced Th2 cytokine levels and lymphocyte accumulation in the lung. In addition, they failed to produce asthmatic responses.
