We at the Cancer Epigenetics Society have lately focused our efforts on expanding the experimental datasets of the Cancer Epigenetics Drug Database with emphasis on three large classes of epigenetics-targeting drugs. These are the inhibitors of the DNA methyltransferases (DNMTi), histone deacetylases (HDACi), and histone methyltransferases (HMTi). Together, the three datasets include more than 2,500 experiments conducted on human cancer cell lines with over 30 functional assays. All databases are currently freely accessible to all users, with no login or registration required. The databases may be accessed directly at https://ces.b2sg.org/cedd/ (Cancer Epigenetics Society news; August 19, 2016).
