Identification of drivers and therapeutic vulnerabilities in anti-androgen resistant prostate cancer cells

Project description:Inhibition of the androgen receptor (AR) by anti-androgens is the standard treatment for castration resistant prostate cancer (CRPC), but it inevitably leads to the development of resistance. We generated two multi anti-androgen resistant cell-line models by treatment of LNCaP cells with enzalutamide (ResA) and RD-162 (ResB). Both cell-lines have an AR independent, non-neuroendocrine phenotype. To identify the resistance mechanisms we performed RNASeq analysis. To this end, the three cell-lines were plated in medium with 5% dextran-coated charcoal (DCC) treated FCS at a density of 1 million cells/well in 6-well plates. After 24 hours of steroid starvation the cells were treated with 10 nM of the androgen dihydrotestosterone (DHT), 10 µM of the anti-androgen enzalutamide, a combination of the two, or vehicle (DMSO) for 18 hours.

Meningioma DNA methylation grouping reveals biologic drivers and therapeutic vulnerabilities (array)

Project description:We report DNA methylation profiling on 565 meningiomas integrated with genetic, transcriptomic, biochemical, proteomic, and single-cell approaches to show meningiomas are comprised of 3 groups with distinct clinical outcomes, biological drivers, and therapeutic vulnerabilities. Merlin-intact meningiomas have the best outcomes and are distinguished by NF2/Merlin regulation of glucocorticoid signaling, apoptosis, and susceptibility to cytotoxic therapy. Immune-enriched meningiomas have intermediate outcomes and are distinguished by immune infiltration, HLA expression, and lymphatic vessels. Hypermitotic meningiomas have the worst outcomes and are distinguished by convergent genetic and epigenetic mechanisms driving the cell cycle and resistance to cytotoxic therapy. Our results establish a framework for understanding meningioma biology, and provide a foundation for new meningioma treatments.

Genetic Screen in a Pre-Clinical Model of Sarcoma Development Defines Drivers and Therapeutic Vulnerabilities

Project description:High-grade complex karyotype sarcomas are a heterogeneous group of more than seventy tumors that vary in histology, clinical course, and patient demographics. Despite these differences, these high-grade sarcomas are treated similarly with varying outcomes. Pre-clinical models of distinct human sarcoma subtypes would advance insights into the relationships between sarcomas and inform therapeutic decisions. We describe the transformation of human mesenchymal stem cells into multiple subtypes of high-grade sarcoma. Using a pooled genetic screening approach, we identified key drivers and potential modifiers of transformation. YAP1, KRAS, CDK4, and PIK3CA were validated as drivers of four distinct sarcoma subtypes, undifferentiated pleomorphic sarcoma (UPS), myxofibrosarcoma (MFS), leiomyosarcoma (LMS), and osteosarcoma (OS). Histologically and phenotypically these tumors reflect human sarcomas including the pathognomonic complex karyotype and YAP1 amplification. Transcriptome analysis confirmed that these tumors accurately recapitulate human disease. This model is a tool that can be used to begin to understand pathways and mechanisms driving human sarcoma development, the relationship between sarcoma subtypes and to identify and test new therapeutic targets for this aggressive and heterogeneous disease.

ONECUT2 Activates Diverse Resistance Drivers of Androgen Receptor-Independent Heterogeneity in Prostate Cancer (RNA-seq)

Project description:Androgen receptor- (AR-) indifference is a mechanism of resistance to hormonal therapy in prostate cancer (PC). Here we demonstrate that the HOX/CUT transcription factor ONECUT2 (OC2) directly activates resistance through multiple drivers associated with adenocarcinoma, stem-like and neuroendocrine (NE) variants. OC2 regulates gene expression by promoter binding, enhancement of chromatin accessibility, and formation of novel super-enhancers. Pharmacologic inhibition of OC2 suppresses lineage plasticity reprogramming induced by the AR signaling inhibitor enzalutamide. These results demonstrate that OC2 activation promotes a range of drug resistance mechanisms associated with treatment-emergent lineage variation in PC.
