EPHB2 and neoplasm: In addition, the tumor weight inhibitory rate was 31.40 and 31.33% for CFPAC-1 and CFPAC-1 control RNAi cells, respectively, with a statistically significant decrease in the corresponding QYHJ group compared with the control group (P<0.05, P<0.01); the tumor weight inhibitory rate was only 18.36% in the CFPAC-1 EphB2 RNAi cells, with no statistically significant difference identified between the QYHJ and control groups (Fig. 1B and C).
