(A) Transwell invasion assay. Daoy cells after transfection of SNCA siRNA1, siRNA2, siRNA3, or GV219‐SNCA‐wt for 24 h. After knockdown transfection, the invasion ability of Daoy cells after transfection of SNCA siRNA was significantly increased compared with the negative siRNA control (N‐con). After overexpression of SNCA, the invasion ability decreased significantly. HPF, high power field (×40). (B) Wound healing assay. Daoy cells showed that the migration ability was significantly increased after transfection of SNCA siRNA for 24 h compared with N‐con. Low power field (×4). **P < .01; ****P < .0001; α‐Syn, GV219‐SNCA‐wt vector transfection
