RNA-seq analysis of NCI-H1693 cells treated with the selective SMARCA2 degrader PRT3789

ABSTRACT: The goal of this study was to examine the transcriptional consequences of selective SMARCA2 degradation in a SMARCA4-deficient non-small cell lung cancer (NSCLC) model. NCI-H1693 cells were treated with the SMARCA2 degrader PRT3789 (50 nM) or vehicle control for 6 h, 48 h, and 72 h. RNA-seq was performed to identify changes in gene expression that could reveal pathways associated with synthetic lethality and clarify the mechanism of action of SMARCA2 degraders in the absence of SMARCA4.

ATAC-seq analysis of NCI-H1693 cells treated with the selective SMARCA2 degrader PRT3789

Project description:The goal of this study was to characterize genome-wide chromatin accessibility changes induced by SMARCA2 degradation in a SMARCA4-deficient non-small cell lung cancer model. NCI-H1693 cells were treated with the selective SMARCA2 degrader PRT3789 (50 nM) or vehicle control (DMSO) for 48 h. ATAC-seq was performed to identify regions of differential accessibility that may help explain the mechanism of synthetic lethality in SMARCA4-deficient contexts.

Enhancer reprogramming underlies therapeutic utility of a SMARCA2 degrader in SMARCA4 mutant cancer [ChIP-Seq]

Project description:Lung cancer is the top cause of cancer mortality. Despite recent advances, the majority of patients with lung cancer still lack effective therapeutic options, underscoring the dire need for additional treatment approaches. Genomic studies have identified frequent mutations in subunits of the SWI/SNF chromatin remodeling complex including SMARCA4 and ARID1A in non-small cell lung cancer with a frequency of up to 33% in advanced stage disease, making it the most frequently mutated complex in lung cancer. Recent reports have identified the paralogue SMARCA2 to be synthetic lethal to SMARCA4 suggesting SMARCA2 is a valuable therapeutic target. However, the discovery of selective inhibitors of SMARCA2 has been challenging. To overcome this hurdle, we have utilized iterative structure-activity relationship (SAR) studies to develop novel, potent and selective SMARCA2 degrading small molecules based on proteolysis targeting chimera (PROTAC) technology. We demonstrated that YD23, our lead SMARCA2 PROTAC, potently and selectively induces degradation of SMARCA2. Mechanistically, we show that SMARCA2 degradation in SMARCA4-mutant cells induces a profound reprograming of the enhancer landscape with marked loss of chromatin accessibility at enhancers of genes involved in cell proliferation. Furthermore, we identified nuclear effectors of the Hippo pathway, YAP/TEAD, as key co-conspirators of SMARCA2 in driving the growth of SMARCA4-mutant cancer cells that can be disrupted by our degrader. Finally, we show that YD23 has a potent tumor growth inhibitory activity in SMARCA4-mutant xenograft tumors. These findings provide the mechanistic basis for development of SMARCA2 degraders as synthetic lethal therapeutics against SMARCA4 mutant tumors.

Genome binding of SMARCA2 and SMARCA4 in lung cancer cells reconstituted with SMARCA4 WT with and without SMARCA2 depletion

Project description:Using ChIP-seq, we identified the genome-wide occupancy of SMARCA2 and SMARCA4 in lung cancer cells (NCI-H1944) reconstituted with SMARCA4 WT. We also determined how SMARCA4 occupancy changed in NCI-H1944 after SMARCA2 depletion.

A selective and orally bioavailable VHL-recruiting PROTAC achieves SMARCA2 degradation in vivo

Project description:Targeted protein degradation offers an alternative modality to classical inhibition and holds the promise of addressing previously undruggable targets to provide novel therapeutic options for patients. Heterobifunctional molecules co-recruit the target and an E3 ligase, resulting in ubiquitylation and proteosome-dependent degradation of the target. The oral route of administration is the option of choice in the clinic, but has only been achieved so far by CRBN- recruiting bifunctional degrader molecules. We aimed to achieve orally bioavailable molecules that selectively degrade the BAF Chromatin Remodelling complex ATPase SMARCA2 over its closely related paralogue SMARCA4, to allow in vivo evaluation of the synthetic lethality concept of SMARCA2 dependency in SMARCA4 deficient cancers. Here we outline structure- and property-guided approaches that led to the first orally bioavailable VHL-recruiting degraders. Our tool compound, ACBI2, shows selective degradation of SMARCA2 over SMARCA4 in ex vivo human whole blood assays and in vivo efficacy in SMARCA4-deficient cancer models. This study demonstrates the feasibility for broadening the E3 ligase and physicochemical space that can be utilised for achieving oral efficacy with bifunctional molecules.

Selective PROTAC-mediated degradation and shRNA-driven knockdown of SMARCA2 in HCC2302 lung adenocarcinoma cells

Project description:SMARCA2 and SMARCA4 are mutually-exclusive, core catalytic subunits for the chromatin remodeling SWI/SNF complex. Mutations in SMARCA4 are common in lung adenocarcinoma and have shown synthetic lethality with loss of SMARCA2 loss of function. The purpose of this project is to answer questions related to the in vivo [mouse xenograft] efficacy of A947, a SMARCA2 degrader. The study involves in vitro versus in vivo comparisons of drug activity, in addition to genetic manipulation of the target. Model system: HCC2302 (RRID:CVCL_V636); Model origin: Lung Adenocarcinoma; Perturbation: A947 (VHL-PROTAC-based degrader)

Development of an orally bioavailable SWI/SNF ATPase degrader and acquired mechanisms of resistance [WES]

Project description:SWI/SNF ATPase degraders have been shown to be effective in enhancer-driven cancers by functioning to impede oncogenic transcription factor chromatin accessibility. Here we developed AU-24118, a first-in-class, orally bioavailable degrader of SMARCA2/4 and PBRM1. AU-24118 demonstrated tumor regression in a castration resistant model of prostate cancer which was further enhanced in combination with enzalutamide. Prostate cancer cell lines exposed to increasing doses of a SWI/SNF degrader developed SMARCA4 bromodomain mutations and ABCB1 overexpression as acquired mechanisms of resistance. While SMARCA4 mutations provided specific resistance to SWI/SNF degraders, ABCB1 overexpression provided broader resistance to other compounds as well as could be overcome with ABCB1 inhibition.
