Biological Activity for I-BET 151 dihydrochloride

I-BET 151 dihydrochloride is a BET bromodomain inhibitor; blocks recruitment of BET to chromatin. Induces apoptosis and G0/G1 cell cycle arrest in MLL-fusion leukemic cell lines in vitro (IC50 values are 15, 26, 120 and 192 nM for NOMO1, MV4;11, MOLM13 and RS4;11 cell lines respectively); reduces BCL2 expression in NOMO1 cells. Improves survival in two rodent models of MLL-fusion leukemia in vivo. Enhances differentiation of human iPSC into megakaryocytes. Also enhances fibroblast reprogramming to hiPSCs at low concentration.

For more information about how I-BET 151 dihydrochloride may be used, see our protocol: Transdifferentiating Fibroblasts into Neurons.

Epigenetics in Cancer Poster

Epigenetics in Cancer Poster

Adapted from the 2015 Cancer Product Guide Edition 3, this poster summarizes the main epigenetic targets in cancer. The dysregulation of epigenetic modifications has been shown to result in oncogenesis and cancer progression. Unlike genetic mutations, epigenetic alterations are considered to be reversible and thus make promising therapeutic targets.

Rheumatoid Arthritis Poster

Rheumatoid Arthritis Poster

Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
