The miR‐92a mimic and PTEN‐wt or PTEN‐mut recombined plasmid were cotransfected into the U14 cervical cancer cells using luciferase activity assay, and the results showed that miR‐92a mimic had no significant effects on the luciferase activity of PTEN‐mut, while that of the PTEN‐wt group decreased by 43% (P < 0.05) (Fig. 3B). This evidence concerns the gene PTEN and cervical cancer.
