Dose–response relationship between genistein concentration and its effects on ATP-dependent CFTR activity. (A) The extent of genistein's augmentation of ATP-induced CFTR current was estimated by the ratio (IATP + Genistein/IATP) of the steady state current amplitude before and after application of various concentrations of genistein in presence of 0.5 mM ATP. (B) Plot of genistein concentration versus the ratio of P o.
