Effects of SR141716A and AM251 on Gq signalling in mouse and human islets. A–c 10 μM SR141716A and AM251 significantly elevated IP1 levels in islets from Gpr55+/+ (a) and Gpr55−/− mice (b) and human donors (c). 500 μM Carbachol (Cch) was used as positive control. Data are expressed as mean ± SEM of three separate experiments, each of 4–6 replicates. *P < 0.05, basal vs. treatment; ***P < 0.001, ****P < 0.0001, basal vs. Cch
