LASP1 Induces Epithelial-Mesenchymal Transition in Lung Cancer through the TGF-β1/Smad/Snail Pathway

(a–d) LASP1 knockdown and overexpression efficiency in TGF-β1-treated A549 and SK-MES-1 cells. After coinfection with 2 ng/ml TGF-β1 and lentivirus containing LASP1 shRNA or 2 ng/ml TGF-β1 and pcDNA-LASP1, the cells were lysated to detect mRNA and protein levels of LASP1. Fold change mRNA expression levels of LASP1 were quantified by RT-qPCR in A549 (a) and SK-MES-1 (c) cells. Western blot confirmed the change of LASP1 protein levels in A549 (b) and SK-MES-1 (d) cells. All quantitative amounts were normalized against GAPDH expression and shown as mean ± SD, n = 6. and vs. the cell alone group without TGF-β1 treatment, and , , and vs. the TGF-β1-treated noninfection group.
