The results showed that there was no significant difference in tumor volume between the QYHJ and control groups following 28 days of measuring in the CFPAC-1 EphB2 RNAi cells, however, a significant inhibition was observed in the CFPAC-1 and CFPAC-1 control RNAi cells (P<0.05; Fig. 1A and C). This evidence concerns the gene EPHB2 and neoplasm.
