Abstract

Background: Increasing evidences reveal that circular RNAs (circRNAs) play crucial functions in Cancer development. However, the expression pattern and roles of circRNAs in infantile hemangiomas (IH) remain unclear.

Methods: In this study, qRT-PCR was performed to determine the expression of circAP2A2, miR-382-5p, and VEGFA in IH tissues and cell lines. Moreover, MTT assay, colony formation, transwell assay, and Western blot analysis were conducted to assess the function of circAP2A2 or miR-382-5p on cell proliferation, and migration in vitro, respectively. Also, dual luciferase assay was used to confirm the interactions among circAP2A2, miR-382-5p, and VEGFA.

Results: CircAP2A2 was confirmed to be highly expressed in IH. CircAP2A2 knockdown or miR-382-5p overexpression decreased the proliferation, colony formation, migration, and invasion of HemECs and HUVEC cells.

Conclusion: CircAP2A2 could promote proliferation and invasion of IH by regulating miR-382-5p/VEGFA axis.
