Interestingly E6 and E7 oncogenes enhance the expression of TWIST-1 in non-small cell lung cancer (NSCLC) cells, and E7 expression has been correlated with E-cadherin, N-cadherin, and TGF-β expression [46], thus promoting the EMT process [47]. The gene discussed is TWIST1; the disease is non-small cell lung carcinoma.
