Methods for treating and preventing the onset and maintainance of multiple drug resistance (MDR) in animals undergoing chemotherapy for cancer are provided. According to the methods, target cells are depleted of adenosine 5'-monophosphate (AMP) and adenosine 5'-triphosphate (ATP) such that the cells are unable to support P-glycoprotein activity. According to one method, a population of target cells is obtained from a host and assayed for loss of methylthioadenosine phosphorylase (MTAse) activity. MTAse catabolizes methylthioadenosine to adenine for endogenous salvage incorporation into the intracellular AMP pool.
