Biochem/physiol Actions

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.
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.

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...

Recent findings have shown that inhibitors targeting bromodomain and extraterminal domain (BET) proteins, such as the small molecule JQ1, are potent growth inhibitors of many cancers and hold promise for cancer therapy. However, some reports have also revealed that JQ1...
