Metastatic castrate-resistant prostate cancer (mCRPC) is a genetically and phenotypically heterogeneous cancer where advancements are needed in biomarker discovery and targeted therapy. A critical and often effective component of treatment includes taxanes. We perform a high-throughput screen across a cohort of 30 diverse patient-derived castrate-resistant prostate cancer (CRPC) organoids to a library of 78 drugs. Combining quantitative response measures with transcriptomic analyses demonstrates that HNF1 homeobox A (HNF1A) drives a transcriptional program of taxane resistance, commonly dependent upon cellular inhibitor of apoptosis protein 2 (cIAP2). Monotherapy with cIAP2 inhibitor LCL161 is sufficient to treat HNF1A+ models of mCRPC previously resistant to docetaxel. These data may be useful in future clinical trial designs.
转移性去势抵抗性前列腺癌(mCRPC)是一种基因和表型异质性癌症,在生物标志物发现和靶向治疗方面仍需取得进展。治疗的一个关键且通常有效的组成部分包括紫杉烷类药物。我们对30个来自不同患者的去势抵抗性前列腺癌(CRPC)类器官组成的队列进行了针对78种药物文库的高通量筛选。将定量反应测量与转录组分析相结合表明,肝细胞核因子1同源框A(HNF1A)驱动了紫杉烷耐药的转录程序,这通常依赖于细胞凋亡抑制蛋白2(cIAP2)。用cIAP2抑制剂LCL161进行单药治疗足以治疗先前对多西他赛耐药的mCRPC的HNF1A+模型。这些数据可能对未来的临床试验设计有用。
