TGFβ-dependent inducibility was reproduced in diverse cell types, including mouse C2C12 myoblasts and LKB1 knockout MEFs (data not shown), immortalized human mammary epithelial MCF10A cells and their Ras-transformed derivatives (MCF10A-Ras MII), immortalized human keratinocytes HaCaT, and human lung adenocarcinoma A549 cells (Fig. S1). This evidence concerns the gene TGFB1 and lung adenocarcinoma.
