DNA methylation is associated with transcription of Snail and Slug genes.

ABSTRACT: Snail and Slug play critical roles in the epithelial to mesenchymal transition (EMT), the mesenchymal to epithelial transition (MET) and in the maintenance of mesenchymal morphology. In this research, we investigated the correlation of DNA methylation with the transcriptional level of these two genes during the EMT/MET process. First, we used several cell lines associated with EMT/MET processes of induced pluripotent stem cell generation and differentiation, trophoblast invasion, as well as cancer progression to examine the association between DNA methylation and transcription levels of these two genes. We found an inverse correlation between DNA methylation of first intron regions and transcription levels of Snail and Slug genes in these EMT/METs. To further verify the results, we treated
