Association between gene of gastrointestinal tumors, the expression of P-glycoprotein and resistance to chemotherapeutic drugs.

The aim of the present study was to examine and discuss the association between multidrug resistance 1 gene () of gastrointestinal tumors, the expression of P-glycoprotein and resistance to chemotherapeutic drugs. In this study, 126 cases of patients with gastrointestinal tumors admitted to hospital from February 2013 to February 2015 were selected. The expression levels of gene were obsreved in the control population and patients before and after treatment by fluoresecent quantitative PCR.
