Reduced expression of vasculogenic markers is an effect of DPN treatment. (A) The expression of VEGF-C and CD34 mRNA was analyzed in control and DPN-treated Granta-519 MCL tumors grown to the same size before analysis, and inhibition of VEGF-C and CD34 by DPN was observed. (B) Treatment with DPN for 24 hours inhibited the expression of VEGF-C. Each group consisted of 5 mice. For vehicle vs DPN, *P < .05. Data are representative of 2 independent experiments.
