Figure 7.
Effect of AGS3 on cAMP production and epithelial cell numbers. A) cAMP levels were measured by ELISA using cell lysates collected from vehicle-treated NRK-Veh cells or genetically modified control NRK-Csh or NRK-AGS3sh cells. cAMP levels are graphed as percentage change normalized to values obtained from NRK-Csh group; n = 8 samples/group. B) NRK-Veh, NRK-Csh, and NRK-AGS3sh cells were portioned into 96-well plates and treated with 10 μM H-89, a selective protein kinase A inhibitor, for 48 h. Cell numbers were measured by DNA fluorescence assay; n = 4–7 samples/group as indicated on bars.
