Correlation of the expression levels of α4GnT mRNA detected in the peripheral blood by real-time RT-PCR and the expression of α4GnT detected by using anti-α4GnT antibody I17K in the subsequently resected gastric cancer. The expression level of α4GnT mRNA detected in the peripheral blood from the patients whose cancer cells express α4GnT is significantly higher than that from the patients whose cancer cells do not express α4GnT (p = 0.0270, Mann-Whitney U test).
