Figure 2From: Prognostic predictive values of gemcitabine sensitivity-related gene products for unresectable or recurrent biliary tract cancer treated with gemcitabine aloneSample distribution for high hET1, dCK, and RRM1 expression in unresectable/recurrent biliary tract cancer. The number in each area is the number of samples with high expression of these biomarkers. dCK, deoxycytidine kinase; hENT1, human equilibrative nucleoside transporter; RRM1, ribonucleotide reductase subunit M1.Back to article page
