In NSCLC cells, PGE2 has been found to induce EMT and enhance cell migration by augmenting ZEB1 and suppressing E-cadherin expression [4–8] via a mechanism requiring stabilization of β-catenin and activation of β-catenin-dependent transcription [4, 7, 8]. The gene discussed is ZEB1; the disease is non-small cell lung carcinoma.
