qRT-PCR showed that PLK1 and FOXM1 levels increased by a factor of 2–3 compared with a control in TGF-β-treated NSCLC cells when the transcriptional factors for EMT including SNAI1, SNAI2, ZEB1, and TWIST increased (Fig. 1g). The gene discussed is TWIST1; the disease is non-small cell lung carcinoma.
