Cell groups with different transfected plasmids

Cell group	Treatment
Blank + TGF-β1 group	Using DMEM medium with 2% FBS and 10 ng/ml TGF-β1 to culture A549 cells
Scramble + TGF-β1 group	After LV-shRNA negative plasmids transfected into A549 cells 6 h, using DMEM medium with 2% FBS and 10 ng/ml TGF-β1 to culture it
Mock + TGF-β1 group	A549 cells transfected with no plasmids and added at the same dose transfecting reagent 6 h later, using DMEM medium with 2% FBS and 10 ng/ml TGF-β1 to culture it
PLOD3-sh + TGF-β1 group	After PLOD3-shRNA plasmids transfected into A549 cells 6 h, using DMEM medium with 2% FBS and 10 ng/ml TGF-β1 to culture it
