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