FIG. 1.
Activation of human and mouse GPR40 by fatty acids and small-molecule agonists. Representative dose responses of various fatty acids induced calcium mobilization in CHO cells stably expressing human (A) and mouse GRP40 (B) measured by the FLIPR assay. EC50 values for various fatty acids are means ± SE of three independent titration experiments. C: Chemical structures of the small-molecule GPR40 agonists and their dose responses (EC50) measured in the FLIPR-based calcium mobilization assay. D: IP3 accumulation assay for GPR40 agonists in human GPR40-HEK293 stable cells.
