WebFeb 26, 2024 · Furthermore, there is evidence to suggest that BRD4-induced up-regulation of c-MYC played a critical role in inducing resistance to everolimus in ER+ breast cancer cells . BET inhibitors OTX015 and JQ1 have been reported to induce c-MYC down-regulation in several cancer types including TNBC [64,65]. Web1 day ago · In contrast, treatment with OTX015 resulted in the upregulation of c-MYC in GBM [11]. Similarly, c-MYC levels are not robustly inhibited by JQ1 in GBM8, GBM10, and GBM22 cells [22]. The above results suggest that the antitumor effect of BRD4 inhibitors can be c-MYC independent in GBM. I-BET151: I-BET151 is a novel non-selective BET …
