Abstract
|
|
|
|
Multi-drug resistance 1 (MDR1) gene encodes P-glycoprotein, which is a transmembrane transporter that acts as an energy-dependent efflux pump of xenobiotics and various chemotherapeutic drugs. To investigate relationships between C3435T (exon 26) and G2677T/A (exon 21) polymorphisms of MDR1 and gastric cancer (GC) or colorectal cancer (CRC), 102 GC patients, 193 CRC patients, and 200 healthy subjects were genotyped by pyrosequencing analysis. The genotype frequencies of 2677T/A and A/A of MDR1 in CRC patients (5.7 %, 1.6 %, respectively) were significantly lower than controls (12.5 %, 5.0 %, respectively) (P?
