PC3 cells were seeded in 24-well plates at a density of 8 × 104 cells/well and transfected with a GFP-tagged LC3 plasmid (GFP-LC3; Addgene plasmid # 11546)52 (link) using FuGENE® HD Transfection Reagent (Roche). Twenty hours after transfection, PC3 cells were treated as indicated and the formation of GFP-LC3 puncta in response to chemicals was observed for 48 hours thereafter using the Zeiss Axiovert 200 inverted fluorescence microscope equipped with the AxioCam HRc microscope color camera and the AxioVision 4.8 software (all from Carl Zeiss, Göttingen, DE).
