As shown in Figure8, ANGPT2 and VWF gene expression levels were significantly lower under IH (0.315 ± 0.152‐fold and 0.276 ± 0.809‐fold, respectively) and drug conditions (0.338 ± 0.0317‐fold and 0.159 ± 0.0861‐fold, respectively) than those in the control group. This evidence concerns the gene VWF and isolated hemihyperplasia.
