Inhibition of DNA Methyltransferase Activity Prevents Tumorigenesis in a Mouse Model of Prostate Cancer
1 Jan 2006
Abstract excerpt
Transcriptional silencing of tumor suppressor genes by DNA methylation plays an important role in tumorigenesis. These aberrant epigenetic modifications may be mediated in part by elevated DNA methyltransferase levels. DNA methyltransferase 1 (DNMT1), in particular, is overexpressed in many tumor types. Recently, we showed that Dnmt1 is transcriptionally regulated by E2F transcription factors and that...
