胶质母细胞瘤(GBM)对治疗具有高度抗性,并且侵入周围脑是导致尽管手术切除仍会复发的癌症标志。随着精准医学的出现,患者衍生的3D系统被认为是潜在的强大GBM临床前模型。在这项研究中,我们筛选了22种抗侵袭化合物的文库(即,NF-κ B、GSK-3-B、考克斯-2和微管蛋白抑制剂)。我们使用3D Matrigel侵袭测定评估毒性和侵袭抑制。接下来,我们选择了三种抑制侵袭的化合物,并在患者来源的胶质母细胞瘤类器官(GBO)中筛选它们。我们开发了一个平台,使用FIJI/ImageJ的可用宏来量化类器官外缘的入侵。我们的数据表明,高通量侵袭筛选可以使用已建立的细胞系和患者来源的3D模型系统来完成。微管蛋白抑制剂化合物对U-251 MG细胞具有最佳功效,然而,在离体患者类器官中,结果是高度可变的。我们的研究结果表明,化合物的疗效与患者肿瘤内和肿瘤间的异质性高度相关。这些结果表明,这些模型可用于评估个人肿瘤治疗策略。
Glioblastoma (GBM) is highly resistant to treatment and invasion into the surrounding brain is a cancer hallmark that leads to recurrence despite surgical resection. With the emergence of precision medicine, patient-derived 3D systems are considered potentially robust GBM preclinical models. In this study, we screened a library of 22 anti-invasive compounds (i.e., NF-kB, GSK-3-B, COX-2, and tubulin inhibitors) using glioblastoma U-251 MG cell spheroids. We evaluated toxicity and invasion inhibition using a 3D Matrigel invasion assay. We next selected three compounds that inhibited invasion and screened them in patient-derived glioblastoma organoids (GBOs). We developed a platform using available macros for FIJI/ImageJ to quantify invasion from the outer margin of organoids. Our data demonstrated that a high-throughput invasion screening can be done using both an established cell line and patient-derived 3D model systems. Tubulin inhibitor compounds had the best efficacy with U-251 MG cells, however, in ex vivo patient organoids the results were highly variable. Our results indicate that the efficacy of compounds is highly related to patient intra and inter-tumor heterogeneity. These results indicate that such models can be used to evaluate personal oncology therapeutic strategies.
