Evaluation of the efficiency of siRNAs in downregulating expression levels of the corresponding target genes. (a) Efficiency of siRNAs specifically targeting ephrinB2 in downregulating mRNA levels of ephrinB2. (b) Efficiency of siRNAs specifically targeting EphB4 in downregulating mRNA levels of EphB4. ∗ p < 0.05 versus negative control.
