In this study, upon TGF-β1 treatment, we observed an induction in NOX isoforms—NOX2 and NOX4—that have time (early and late) and cellular localization (nucleus and autophagosome co-localized) dependent effects in mediating EMT associated cell proliferation and migration through activation of the focal adhesion kinase (FAK)/SRC pathway in HeLa, human cervical cancer cells. The gene discussed is NOX4; the disease is cervical carcinoma.
