CircATP5SL promotes infantile haemangiomas progression via IGF1R regulation by targeting miR-873-5p.

ABSTRACT: Infantile haemangiomas (IH) are the most common soft-tissue tumours in infants. Several studies have demonstrated the importance of circular RNA (circRNA) for the regulation of various cancer cells. The present study aims to evaluate the functions and molecular mechanisms of circATP5SL in IH progression. In this study, we found that circATP5SL is significantly dysregulated in IH. We conducted Transwell, MTT, and flow cytometry analysis to evaluate the role of circATP5SL in IH cell proliferation, invasion, migration, and apoptosis. Meanwhile, by using subcellular distribution detection, as well as dual-luciferase reporter test and RIP analysis, it has been confirmed that miR-873-5p directly binds to the 3'UTR of IGF1R mRNA, thereby inhibiting the expression of IGF1R. Besides, circATP5SL pro
