IL‐6 also induces EMT in vitro in immortalized epithelial oral cells, in a JAK2/STAT3/Snail1‐dependent way (Yadav et al., 2011), in lung adenocarcinoma cells (in a STAT3‐Snail1‐dependent fashion) (Zhao et al., 2014) and in NSCLC cells (Lee et al., 2016; Shintani et al., 2016). The gene discussed is SNAI1; the disease is non-small cell lung carcinoma.
