In the mouse PD model, we found that miR‐221 was significantly lower than that in the healthy control group; however, overexpression of miR‐221 mimics, as well as overexpression of miR‐221 mimics and Bim, can markedly rescue the expression of miR‐221 (Figure 2c, F = 68.8). Here, BCL2L11 is linked to Parkinson disease.
