EGFL7 and neoplasm: Compared with the blank and miR-126 inhibitors + si-EGFL7 groups, significant increases in tumor sizes were observed in the miR-126 inhibitors group at the first 10 days after transfection (both P < 0.05), while the tumor size was decreased in the miR-126 mimics and si-EGFL7 groups (all P < 0.05) (Figure 6A).
