SDA promotes the α-syn clearance through activation of PGC-1α/Nrf2 signaling. a Representative immunoblots and densitometry data for α-syn, Nrf2 and PGC-1α in the inducible PC12/α-syn cells treated with doxycycline (Dox) followed by SDA; b Representative immunoblots and densitometry data for Nrf2 and α-syn levels in the inducible PC12/α-syn cells transfected Nrf2 siRNA or scrambled siRNA. Data from three independent experiments were expressed as mean ± SEM (^# P < 0.05, ^### P < 0.001 compared to control group; ^* P < 0.05, ^*** P < 0.001 compared to Dox-treated group; ^&&& P < 0.001)
