BET bromodomain inhibitor. Downregulates Myc expression, causes G1 cell cycle arrest and attenuates cell proliferation in human pancreatic neuroendocrine tumors. Arrests the growth of T cell acute lymphoblastic leukemia cells in vitro (EC50 = 91.2 nM). Also enhances the antitumor effect of rapamycin (Cat. No. 1292) in vitro and attenuates rapamycin induced Akt activation. Orally bioavailable.

Epigenetics Scientific Review
Written by Susanne Müller-Knapp and Peter J. Brown, this review gives an overview of the development of chemical probes for epigenetic targets, as well as the impact of these tool compounds being made available to the scientific community. In addition, their biological effects are also discussed. Epigenetic compounds available from Tocris are listed.
Epigenetics Research Bulletin
Produced by Tocris and updated in 2014, the epigenetics research bulletin gives an introduction into mechanisms of epigenetic regulation, and highlights key Tocris products for epigenetics targets including:
- DNA Methyltransferases

Cell Cycle & DNA Damage Repair Poster
In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.
