Histone Deacetylase Inhibitor Largazole Deactivates A Subset of Superenchancers and Causes Mitotic Chromosome Mis-alignment by Suppressing SP1 and BRD4.

Histone deacetylase inhibitors have been investigated as potential therapeutic agents for cancer and other diseases. HDIs are known to promote histone acetylation, resulting in an open chromatin conformation and generally increased gene expression. In previous work, we reported that a subset of genes, particularly those regulated by superenhancers, can be suppressed by the HDAC inhibitor largazole.
