The field of epigenetics encompasses studies about the ways in which genes are influenced
by various external stimuli, such as drugs, chemicals, and the environment. Over the last few years, it
has become an increasingly important area of research. Recently, substantial evidence has been
presented for the claim that certain diseases, including cancer, exhibit epigenetic changes. In the
present overview, we will give a brief summary of recent observations on epigenetics and cancer as
well as of the ways in which various small molecules may influence the epigenetic state of cells.
Keywords: Cancer, CpG islands, DNA methylation, epigenetic drugs, epigenetics, TET proteins.
