Project description:Competitive inhibitors of acetyl-lysine binding to the bromodomains of the BET (bromodomain and extra terminal) family are being developed for the treatment of solid and heme malignancies. BET family member BRD4 function at enhancers/super-enhancers has been shown to sustain signal-dependent or pathogenic gene expression programs. Here we tested the hypothesis that the transcription factor drivers of castration-resistant prostate cancer (CRPC) clinical progression, including the Androgen Receptor (AR), are critically dependent on BRD4 and thus represent a sensitive solid tumor indication for the BET inhibitor ABBV-075. DHT-stimulated transcription of AR target genes was inhibited by ABBV-075 without significant effect on AR protein expression. Further, ABBV-075 disrupted DHT-stimulated recruitment of BET family member BRD4 to gene regulatory regions co-occupied by AR, including the well-established PSA and TMPRSS2 enhancers. Persistent BET inhibition disrupted the composition and function of AR occupied enhancers as measured by a reduction in AR and H3K27Ac ChIP signal and inhibition of eRNA transcription. ABBV-075 displayed potent anti-proliferative activity in multiple models of resistance to second generation anti-androgens and inhibited the activity of AR-V7 and the AR LBD gain-of-function mutations, F877L and L702H. ABBV-075 was also a potent inhibitor of MYC and the TMPRSS2-ETS fusion protein, important parallel transcription factor drivers of CRPC.

Project description:We comprehensively analyzed the differentially expressed mRNAs (DEmRNAs) and lncRNAs (DElncRNAs) underlying the antitumor functions of BET inhibitors of human HCC cells using RNA sequencing (RNA-Seq). The pan-BET inhibitor ABBV-075 and BD2 specific inhibitor ABBV-744 attenuates the IFNγ-induced inflammatory response. In addition, BD2 inhibitors were predominantly effective in inflammatory response.

Project description:To study the consequence of HNF4G target genes expression with ABBV-075 treatment in cells that have BETi-independent HNF4G expression, we performed RNA-Seq on 22Rv1 cells that exogenously express HNF4G using GFP expression as control.

Project description:Diffuse intrinsic pontine glioma (DIPG), a lethal pediatric cancer driven by H3K27M oncohistones, exhibits aberrant epigenetic regulation and stem-like cell states. Here, we uncover an axis involving H3.3K27M oncohistones, CREB5/ID1, which sustains the stem-like state of DIPG cells, promoting malignancy. We demonstrate that CREB5 mediates elevated ID1 levels in the H3.3K27M/ACVR1WT subtype, promoting tumor growth; while BMP signaling regulates this process in the H3.1K27M/ACVR1MUT subtype. Furthermore, we reveal that H3.3K27M directly enhances CREB5 expression by reshaping the H3K27me3 landscape at the CREB5 locus, particularly at super-enhancer regions. Additionally, we elucidate the collaboration between CREB5 and BRG1, the SWI/SNF chromatin remodeling complex catalytic subunit, in driving oncogenic transcriptional changes in H3.3K27M DIPG. Intriguingly, disrupting CREB5 super-enhancers with ABBV-075 significantly reduces its expression and inhibits H3.3K27M DIPG tumor growth. Combined treatment with ABBV-075 and a BRG1 inhibitor presents a promising therapeutic strategy for clinical translation in H3.3K27M DIPG treatment.
