tokens: Treatment of N18TG-2 cells with a demethylating agent , 5-aza-deoxycytidine , resulted in an expression of mlt 1 , indicating that the repression of mlt 1 is attributable to methylation Thus , mlt 1 is a novel target gene that is silenced by methylation during liver tumorigenesis initiated by SV40 T antigen .
