Biochem/physiol Actions

I-BET762 (GSK525762) is a selective inhibitor of bromodomain and extra terminal (BET) domain proteins BRD2, BRD3 and BRD4 with IC50 values of 32.5–42.5 nM and no interaction with other bromodomain-containing proteins. I-BET mimicks acetylated histone, preventing the protein-protein interaction between acetyl-lysines and the BET reader protein. This was shown to block expression of inflammatory genes in activated macrophages and confer protection against endotoxic shock and bacterial sepsis. I-BET762 also showed potent anti-myeloma activity in vitro and in vivo.
I-BET762 possesses anti-inflammatory property by controlling the pro-inflammatory gene expression. I-BET762 hinders the MYC (proto-oncogene) expression in cellular models. This action of I-BET762 might serve as an effective therapy in treating prostate cancer.

High-grade gliomas defined by histone 3 K27M driver mutations exhibit global loss of H3K27 trimethylation and reciprocal gain of H3K27 acetylation, respectively shaping repressive and active chromatin landscapes. We generated tumor-derived isogenic models bearing this mutation and show that it

The NUP214-ABL1 fusion is a constitutively activated tyrosine kinase that is significantly associated with overexpression of the TLX1 and TLX3 transcription factors in T cell acute lymphoblastic leukemia (T-ALL). Here we show that NUP214-ABL1 cooperates with TLX1 in driving T-ALL development
