[Expression of multidrug resistance gene in nasopharyngeal carcinoma cells after irradiation exposure].

OBJECTIVE To examine the changes in the function and expression of multidrug resistance gene (mdr1) and P-gly-coprotein (P-gp) in nasopharyngeal carcinoma (NPC) CNE1 cell following irradiation for determining the sequential order of radiotherapy and chemotherapy in the treatment of NPC. METHODS The expressions of mdr1 gene and its protein P-gp as well as… CONTINUE READING
