It has been discovered that by determining or measuring a person's glutathione-s-transferase (GST) mu activity one can determine or measure the individual's resistance to drugs, particularly to chemotherapeutic drugs. Approximately 50% of the human population exhibit substantially no GST mu activity, with the remaining 50% showing GST mu activity. This remaining 50% of the population accordingly, when treated with drugs, such as a chemotherapeutic drug for cancer therapy, show less effective response to the drug therapy than the other 50% of the population which have substantially no GST mu activity, since GST mu tends to deactivate drugs. Accordingly, a person having GST mu activity would exhibit drug resistance and would not benefit as much by or be as good a candidate for cancer chemotherapy as a person who has no GST mu activity. <IMAGE> |
