Growth arrest-specific protein 6 (Gas6) pretreatment inhibits transforming growth factor (TGF)-β1-induced epithelial-mesenchymal transition (EMT) in lung epithelial cells (ECs). (A–C) LA-4 and ATII ECs were pretreated with 400 ng/mL Gas6 for 20 h prior to 10 ng/mL TGF-β1 treatment for 48 or 72 h. (A) Morphological changes in LA-4 ECs were examined by phase-contrast microscopy. Scale bars = 50 μm. Results are representative of three independent experiments. (B) Immunoblots of total cell lysates were performed with anti-E-cadherin, -N-cadherin, or -α-SMA antibodies. Densitometry of the relative abundances of the indicated EMT markers. Alpha-tubulin was used as a control. (C) The amount of EMT markers’ mRNAs in cell lysates was analysed by real-time PCR and normalized to that of hypoxanthine phosphoribosyltransferase. Values represent the mean ± S.E. of three independent experiments. * P < 0.05; compared with control; + P < 0.05 as indicated.
