Previously published studies have described the ability of triclosan to increase motility of H460 lung cancer cells through not only EMT but also a FAK/Akt and Rac‐1‐dependent mechanism (Winitthana, Lawanprasert, & Chanvorachote, 2014) and to increase motility of LNCaP prostate cancer cells by an androgen receptor‐mediated mechanism (Kim, Hwang, Shim, & Choi, 2015). Here, RAC1 is linked to lung cancer.
