Effects of UTMD-mediated miR-21 transfection on apoptosis, metastasis, and Wnt/Akt pathway-related genes. (A) Western blot was used to detect the effects of the miR-21 plasmid on phosphorylated (p)-Akt, Akt, Bax, Bcl-2, Wnt, β-catenin, MMP-9, and EGFR expression in HeLa cells; β-actin was an internal reference (ultrasonic intensity of 1.5 W/cm2). (B) RT-qPCR was used to detect the effects of miR-21 plasmid on Akt, Bax, Bcl-2, Wnt, β-catenin, MMP-9, and EGFR expression in HeLa cells; β-actin was an internal reference (ultrasonic intensity of 1.5 W/cm2). * P<0.05, ** P<0.01, and *** P<0.001 vs untreated; @
