本研究旨在建立一种可用于临床前研究的自体发光膀胱癌(UBC)异种移植动物模型。该研究使用了由六个(luxCDABEfrp)基因组成的人源化细菌来源的lux报告系统,以表达在人UBC J82,J82-Ras和SW 780细胞中产生生物发光信号所需的组分,而无需外源底物。免疫缺陷的裸鼠接种Lux-expressing UBC细胞,以发展自身生物发光异种移植肿瘤,通过成像和体格检查进行监测。建立了表达Lux的自生物发光J82-Lux、J82-Ras-Lux和SW 780-Lux细胞系。来源于致瘤性Lux-expressing自体生物发光J82-Ras-Lux细胞的异种移植肿瘤允许在动物中存在可触知肿瘤之前通过肿瘤发展成像进行连续、非侵入性、实时监测。使用表达Lux-expressing的自体生物发光致瘤细胞使我们能够通过肿瘤细胞植入、适应和生长到动物中可见/可触知肿瘤来监测异种移植肿瘤发展的整个过程。
The study was to develop an auto-bioluminescent urinary bladder cancer (UBC) xenograft animal model for pre-clinical research. The study used a humanized, bacteria-originated lux reporter system consisting of six (luxCDABEfrp) genes to express components required for producing bioluminescent signals in human UBC J82, J82-Ras, and SW780 cells without exogenous substrates. Immune-deficient nude mice were inoculated with Lux-expressing UBC cells to develop auto-bioluminescent xenograft tumors that were monitored by imaging and physical examination. Lux-expressing auto-bioluminescent J82-Lux, J82-Ras-Lux, and SW780-Lux cell lines were established. Xenograft tumors derived from tumorigenic Lux-expressing auto-bioluminescent J82-Ras-Lux cells allowed a serial, non-invasive, real-time monitoring by imaging of tumor development prior to the presence of palpable tumors in animals. Using Lux-expressing auto-bioluminescent tumorigenic cells enabled us to monitor the entire course of xenograft tumor development through tumor cell implantation, adaptation, and growth to visible/palpable tumors in animals.
