Epigenet Insights 2020 21;13:2516865720964808. Epub 2020 Oct 21.

Faculty of Veterinary Medicine, Hawassa University, Ethiopia.

Aberrant promoter DNA hypermethylation is a typical characteristic of cancer and it is often seen in malignancies. Recent studies showed that regulatory cis-elements found up-stream of many tumor suppressor gene promoter CpG island (CGI) attract DNA methyltransferases (DNMT) that hypermethylates and silence the genes. As epigenetic alterations are potentially reversible, they make attractive targets for therapeutic intervention. Read More
