Transfection efficiency of transfected cells. (a) The transfection efficiencies of PC12 cells transfected with both miR-326 inhibitor and shDOR or the relative control (NC) were 80–90%. (b) After cotransfection with miR-326 and DOR inhibitors at the same time, the expression levels of miR-326 were decreased, and DOR expression was higher than that in the control, although lower than that in cells transfected with miR-326 inhibitor (**P < 0.01; ****P < 0.001)
