Gupta  SK,  Singh A,  Srivastava M, Designing of drug for removal of methylation from Tcf21 gene in lung cancer, Onl J Bioinform., 11 (1):149-155, 2009. Tcf21 is a specific tumor suppressor gene associated with lung cancer. This gene is inactivated because of CpG hypermethylation of the promoter region. Removal/inhibition of methylation could prevent metastasis. This work describes DNA-ligand docking for removal of methylation. Computational approaches were used to dock drugs with methylated DNA to remove methylation by converting 5-methyl cytosine into cytosine. The in-silico docking results showed that decitabine, a DNA binding drug, could remove methylation.
