(Submitter supplied) BET inhibitors are promising therapeutic agents for the treatment of triple-negative breast cancer (TNBC), but the rapid emergence of resistance necessitates investigation of combination therapies and their effects on tumor evolution. Here, we show that palbociclib, a CDK4/6 inhibitor, and paclitaxel, a microtubule inhibitor, synergize with the BET inhibitor JQ1 in TNBC lines. High-complexity DNA barcoding and mathematical modeling indicate a high rate of de novo acquired resistance to these drugs relative to pre-existing resistance. more...

(Submitter supplied) CDK4/6 kinase inhibitors have shown great promise in clinical trials in various cancer types and have recently entered clinical trial for advanced prostate cancer. Although patients are expected to respond well to this class of drugs, development of resistance in some patients is anticipated. To pre-empt this and study how prostate cancer may evade CDK4/6 inhibition, new resistance models were generated from LNCaP and LAPC4 prostate cancer cells cells by prolonged culturing in presence of 0.5uM palbociclib. more...

(Submitter supplied) RNA-seq was performed to compare the transcriptional programmes of A375 cells treated with Palbociclib or GSK3326595 compared to untreated cells Cyclin dependent kinase 4/6 (CDK4/6) inhibitors are an established treatment in estrogen receptor positive breast cancer and are currently in clinical development in melanoma; a tumour that exhibits high rates of CDK4 activation. We analyzed melanoma cells with acquired resistance to the CDK4/6 inhibitor palbociclib, and demonstrated that palbociclib-mediated inhibition of PRMT5 is essential for sensitivity to CDK4/6 inhibitors. more...

(Submitter supplied) Triple negative breast cancer (TNBC) is a heterogeneous and clinically aggressive disease for which there is no targeted therapy. Here we report the preferential and high sensitivity of TNBCs to BET bromodomain inhibitors such as JQ1 manifested by cell cycle arrest in early G1, apoptosis, and induction of markers of luminal epithelial differentiation in vitro and in vivo. The sensitivity of TNBC and other tumor types to BET inhibition establishes a rationale for clinical investigation, and a motivation to understand mechanisms of resistance. more...

(Submitter supplied) To determine the global transcriptome changes in mantle cell lymphoma cells following treatment with the BET bromodomain antagonist, JQ1 Mantle Cell Lymphoma (MCL) cells exhibit increased B cell receptor and NFkB activities. The BET protein BRD4 is essential for the transcriptional activity of NFkB. Here, we demonstrate that treatment with the BET protein bromodomain antagonist (BA) JQ1 attenuates MYC and CDK4/6, inhibits the nuclear RelA levels and the expression of NFκB target genes including Bruton’s Tyrosine Kinase (BTK) in MCL cells. more...

(Submitter supplied) BET bromodomain inhibitors (BBDI) are promising therapeutic agents in triple-negative breast cancer (TNBC). However, not all tumors respond and acquired resistance emerges rapidly even in the responders. Using CRISPR and small molecule inhibitor screens combined with comprehensive molecular profiling of BBDI response and resistance in TNBC cell lines, we identified numerous synthetic lethal interactions with BBDIs as well as genes that when deleted confer resistance. more...
