ANRIL was directly targeted by miR-186. (A) Complementary binding sites predicted using bioinformatics program (TargetScan, starBase). (B) Luciferase reporter assay verified the fluorescence between ANRIL wild type/mutant and miR-186 mimics/control. (C) miR-186 expression was downregulated in cervical cancer tissues compared to adjacent noncancerous tissues. (D) miR-186 expression was downregulated in cervical cancer cell lines (HeLa, CaSki, SiHa, HT-3, and C33A) compared to human epidermal cells (HaCaT). Data are presented as the mean ± SEM. *p < 0.05, **p < 0.01 compared to the si-control group.
