Effect of kinase inhibitors on cicaprost-mediated desensitization of TP signaling in HEK.a10 and HEK.b3 cells. HEK.a10 (A–C) or HEK.b3 (D–F), transiently co-transfected with pCMV:Ga11, were preloaded with Fura2/AM and stimulated with 1 mM cicaprost followed by 1 mM U46619 (A and D). Alternatively, cells were preincubated with 50 nM GF …
WebbPEPA binds to the activated receptor to stabilize it, which decreases overall desensitization.
