Biochem/physiol Actions

It binds to bromodomain and extra-terminal domain (BET) proteins and inhibits their binding to the chromatin. This in turn prevents gene transcription. OTX015 has been shown to inhibit proliferation of cells in haematological malignancies.
OTX015 is a potent inhibitor of the BET bromodomain proteins 2, 3, and 4 (BRD2/3/4).

Analysis of The Cancer Genome Atlas and other published data of head and neck squamous cell carcinoma (HNSCC) reveals somatic alterations of the Hippo-YAP pathway in approximately 50% of HNSCC. Better strategies to target the YAP1 transcriptional complex are sought.

The bromodomain and extraterminal family members are epigenetic readers and transcriptional coactivators which are critically involved in various biological processes including tumorigenesis. BRD4 has been increasingly appreciated as a key oncogene and promising anticancer target. Here, we sought to characterize

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
