The E-cadherin levels could be restored with the use of HDAC inhibitor Trichostatin A (7-[4-(dimethylamino)phenyl]-N-hydroxy-4,6-dimethyl-7-oxohepta-2,4-dienamide) or DNMT inhibitor 5′-Aza-deoxycytidine and the effects are partly linked with the suppression of ZEB1 in the non-small cell lung cancers [130]. Here, CDH1 is linked to non-small cell lung carcinoma.
