Figure 1. Activation of EMT Programming by TGF-β1 is Associated with LINE-1 Expression in Human Bronchial Epithelial Cells.

Figure 1

(A) BEAS-2B whole cell lysates isolated from cells stimulated with 3 ng/mL TGF-β1 for 48 hours or control were analyzed by immunoblotting using antibodies against LINE1 (L1) ORF1 protein (ORF1p), E-cadherin, vimentin or GAPDH. (B) Total RNA from untreated or treated with 3 ng/ml TGF-β1 for 8 hours, and 1 µg of RNA was subjected to cDNA synthesis. Samples were analyzed by RT-qPCR using specific primers for human L1 (ORF1 and ORF2). Expression levels are shown as the mean of triplicates with SEM relative to controls. (C) Whole cell lysates from cells stimulated with different concentrations of TGF-β1 for 48 hours or control were analyzed for expression of L1 ORF1p by immunoblotting. Data are representative of two or more independent experiments.
