Effect of GPR61, GPR62 and GPR135 expression on cAMP and inositol phosphate production in HEK293T cells. Basal (A–C) and forskolin-stimulated (D–F) cAMP accumulation in HEK293 cells as a function of transfected vector DNA expressing HA-GPR61, HA-GPR62 and HA-GPR135. Inositol phosphate (IP1) production was determined in HEK293T cells transfected with different quantities of HA-GPR61 (G), HA-GPR62 (H) and HA-GPR135 (I) expression vectors in the absence or presence of 1 µM melatonin (MLT). (J) Representative western blot of HA-GPR61, HA-GPR62 or HA-GPR135 expression control of experiments shown in panels A–I. Data are expressed as mean ± SEM. from three independent experiments performed in triplicates. ***P < 0.0001.
