DNA methylation and genetic instability in colorectal cancer cells

18 Mar 1997

Abstract excerpt

Apparent alterations in DNA methylation have been observed in many cancers, but whether such alterations represent a persistent alteration in the normal methylation process is not known. In this study, we report a striking difference in the expression of exogenously introduced retroviral genes in various colorectal cancer cell lines. Extinguished expression was associated with DNA methylation and could be...
