摘要 Abstract

中文摘要
尽管靶向治疗的开发不断增长,药物失败率已上升至约95%。正如临床试验所证明的,单靠靶向基因本身并不能预测患者对某种药物的反应是否会带来更长的预期寿命。正如模式生物研究所显示的,药物的效应及其背后的机制取决于整个多组学。但多组学数据具有小队列、噪声大、高维度的特点,即极难建模。 我们开发了基于量子力学的人工智能和机器学习(AI/ML)以克服这些挑战 [doi: 10.1158/1538-7445.AM2025-CT227]。 我们在对例如85例星形细胞瘤患者全基因组的无监督建模中演示了我们的算法。机制性解释显示,该模型盲式地去除了批次效应,分离了正常的人口统计学变异,并发现了一种疾病特异性的全基因组DNA拷贝数变异模式。该模式被用于推导出一个可操作的患者总生存期(OS)预测指标以及使其肿瘤致敏的基因靶点。 我们在约50-250名患者的互斥集合的联邦研究中,对该预测指标和建模进行了计算验证。该建模在每一项研究中,均在II、III和IV级星形细胞瘤即胶质母细胞瘤(GBM)患者中反复发现了该预测指标的一种表征。 我们在一项79例GBM患者的临床试验中对该预测指标进行了实验验证,最初是回顾性的,并在为期四年的随访中也进行了前瞻性验证 [doi: 10.1063/1.5142559, 10.1145/3624062.3624078]。在所有队列中,该预测指标与生存的一致性达75-95%,比所有标准治疗指标都更准确。在Complete Genomics、Illumina和Ultima全基因组测序之间具有100%的可重复性,纳入Affymetrix和Agilent DNA微阵列时可重复性>99%,该预测指标也是最精确的。 在此,我们描述了对预测可使肿瘤致敏的基因靶点以及预测的肿瘤反应水平这两者的功能基因组学实验验证。设计了向导RNA,并利用一种慢病毒CRISPR-Cas9一体化载体来敲除候选靶点。在蛋白水平上使用Western blot进行了敲除验证。在患者来源的GBM细胞系中进行敲除,导致细胞活力和增殖显著减弱。减弱程度在不同细胞系之间存在显著差异,与其基于全基因组的预测反应相一致。 我们得出结论,我们基于量子力学的多张量AI/ML解决了这个已有75年历史的难题,即从全基因组正确预测GBM患者的OS、使肿瘤致敏的基因靶点以及肿瘤对该靶向的反应。

Despite the growth in targeted therapy development, the drug failure rate has increased to ~95%. As clinical trials demonstrated, the targeted gene alone does not predict whether patients would have longer life expectancy in response to a drug. As studies with model organisms showed, the effect of the drug, and the mechanisms underlying it, depend on the entire multi-ome. But multi-omic data are small-cohort, noisy, and high-dimensional, i.e., extremely difficult to model. We have developed our quantum mechanics-based artificial intelligence and machine learning (AI/ML) to overcome these challenges [doi: 10.1158/1538-7445.AM2025-CT227]. We demonstrated our algorithms in the unsupervised modeling of, e.g., whole genomes of 85 astrocytoma patients. Mechanistic interpretation showed that the model blindly removed batch effects, separated normal demographic variations, and discovered a disease-specific genome-wide pattern of DNA copy-number alterations. This pattern was used to derive an actionable predictor of patients' overall survival (OS) and gene targets to sensitize their tumors. We computationally validated both the predictor and the modeling in federated studies of mutually-exclusive sets of ~50-250 patients. The modeling repeatedly discovered a representation of the predictor in every study, in astrocytoma grades II, III, and IV, i.e., glioblastoma (GBM), patients. We experimentally validated the predictor in a clinical trial in 79 GBM patients, initially retrospectively, and, in a four-year follow up, also prospectively [doi: 10.1063/1.5142559, 10.1145/3624062.3624078]. In all the cohorts, the predictor, with 75-95% concordance with survival, was more accurate than all standard-of-care indicators. With 100% reproducibility among Complete Genomics, Illumina, and Ultima whole-genome sequencing, and >99% when including Affymetrix and Agilent DNA microarrays, the predictor was also the most precise. Here, we describe functional genomics experimental validation of both a gene target predicted to sensitize the tumors, as well as the predicted tumors' response level. Guide RNAs were designed and a lentiviral CRISPR-Cas9 all-in-one vector was utilized to knock out the candidate target. Knockout validation at the protein level was performed using Western blot. Knockout in patient-derived GBM cell lines resulted in significantly attenuated cell viability and proliferation. The level of attenuation was significantly different between the cell lines, in agreement with their whole genome-based predicted response. We conclude that our quantum mechanics-based multi-tensor AI/ML solved the 75-year-old problem of correctly predicting - GBM patients' OS, gene targets to sensitize the tumors, and the tumors' response to their targeting - from their whole genomes.
