Liu et al. reported that EGCG inhibited not only TGF-β-induced cell migration and invasion but also TGF-β-induced epithelial-to-mesenchymal transition (EMT) via inhibition of the Smad2 and ERK1/2 signaling pathways in nonsmall cell lung cancer (NSCLC) cells [113]. Here, TGFB1 is linked to non-small cell lung carcinoma.
