Background

Acute myeloid leukemia (AML) is characterized by malignant clonal disorder of blood cells with high relapse rate and low survival rate. Circular RNAs (circRNAs) have shown their important regulatory roles in AML progression. Here, we intended to disclose the role of circular RNA protein tyrosine kinase 2 (circ-PTK2) in the progression of AML and illustrate the potential working mechanisms.

Methods

3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and colony formation assay were conducted to analyze cell proliferation ability, and the apoptosis rate was assessed by flow cytometry. Dual-luciferase reporter assay was used to validate the direct interaction between microRNA-330-5p (miR-330-5p) and circ-PTK2 or forkhead box M1 (FOXM1).

Results

Circ-PTK2 was highly expressed in AML. Circ-PTK2 interference suppressed the proliferation and triggered the apoptosis of AML cells. Circ-PTK2 directly bound to miR-330-5p. Si-circ-PTK2-mediated inhibition on the malignant behaviors of AML cells was partly counteracted by the addition of anti-miR-330-5p. MiR-330-5p directly interacted with FOXM1 messenger RNA (mRNA), and FOXM1 overexpression partly reversed miR-330-5p-induced influence in AML cells. Circ-PTK2 up-regulated FOXM1 expression through sponging miR-330-5p in AML cells.

Conclusion

Circ-PTK2 promoted the proliferation and hampered the apoptosis of AML cells through targeting miR-330-5p/FOXM1 axis."xsd:string
