Effects of silencing α-synuclein expression on DA levels. Changes in DA levels were detected by HPLC. DA levels were significantly increased in MN9D/α-SYN− cells compared with MN9D and MN9D/CON cells [n = 6, F = 161.774, df(total) = 17, **p < 0.001 compared with MN9D cells, **p < 0.001 compared with MN9D/CON cells]. Differences in DA levels between the MN9D and MN9D/CON cells were not statistically significant
