Figure 8. Rescue experiment, miR-4469 reversed the effects of circRNA_141539 on CDK3 expression and cell proliferation. (A) qRT-PCR assay showed the effects of circRNA_141539/miR-4469 axis on CDK3 mRNA expression. *P < 0.05, **P < 0.01 versus corresponding NC group. (B) MTT assay showed the effects of circRNA_141539/miR-4469 axis on cell proliferation. *P < 0.05, **P < 0.01 versus corresponding NC group.
