It is concluded that, although overexpression of P-glycoprotein did not impair pH(i) regulation in U-2 OS cells, the kinetic parameters of the Na ( + ) /H ( + ) exchanger were altered, suggesting a functional relationship between the two membrane proteins

Expression of this glycoprotein was strongly dependent on activation of BMM phi by a combination of IFN-gamma and LPS but was only marginally induced by either stimulant alone

These data suggest that, in the absence of xenobiotic substrates, P-glycoprotein activity can affect cellular pHi
