Curcumin, an active biphenolic molecule present in turmeric (Curcuma longa), has been reported to elicit plethora of health protective effects. The present study was carried out in vitro, in vivo and in silico to investigate the modulatory effects of curcumin on erythrocyte membrane Na+/K+-ATPase activity. In vitro curcumin (105 M to 108 M) was incubated with human erythrocytes membrane. In vivo curcumin (340 mg/kg . and 170 mg/kg .) was supplemented to wistar rats for 21 days. In silico, catalytic unit a of Na+/K+-ATPase () protein was used as a receptor for the natural ligand ATP to study curcumin-mediated docking simulation using AutoDock4. The in vitro effect of curcumin on the Na+/K+-ATPase activity in human erythrocytes was biphasic. | The modulation of erythrocyte Na+/K+-ATPase activity by curcumin
