TGFB1 and lung adenocarcinoma: ViceninII, which is flavonoid glycoside extracted from Dendrobium officinale, inhibits transforming growth factor-β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) by deactivating TGF-β/Smad and PI3K/Akt/mTOR signalling pathways in lung adenocarcinoma A549 and H1299 cells [177].
