Stel B promoted autophagic flux in A549 cells.
A549 cells were transfected with tandem fluorescent mRFP-GFP-tagged LC3 plasimd (ptfLC3) for 24 h. Then the transfected cells were treated with 1 μM of Stel B for 0, 3, 6, 17, 24 h, followed by confocal fluorescence microscopy. Arrows indicate autophagosomes. Bar = 10 μm. Data represent three independent experiments.
