Effect of gA, curcumin (cur), ouabain (oua), and a combination of curcumin and gA, or curcumin and ouabain on ATP hydrolysis by the ABCG2 transporter, on ATP hydrolysis by the Na+,K+-ATPase, and on total ATP hydrolysis by both transporters in crude membrane vesicles from HEK-ABCG2 cells. Single, double, and triple asterisks indicate a difference compared with the basal activity with a p value ≤ 0.05, ≤ 0.01, and ≤ 0.001 respectively.
