after incubation with VAPFPEVF (17.5
μM), YFYPEL (0.03 μM), and YQEPVLGPVRGPFPIIV (0.4 μM),
respectively, of (A) HGT-1 cells with (light gray bars) and without

bars), mock-transfected (dark gray bars), and TAS2R16kd (light gray
bars) HGT-1 cells; and (E–G) non-transfected (black bars),
mock-transfected (dark gray bars), and TAS2R38kd (light gray bars)
