【摘要】：目的:建立ABCE1-GFP(+)肺腺癌裸鼠動物模型,并進行免疫組化檢測,為進一步探索ABCE1作為診斷治療非小細胞肺癌靶點提供有用的工具。方法:應用前期實驗中構建的穩(wěn)定轉染重組質粒p EGFPC1-ABCE1及空載體p EGFP-C1的LTEP-a-2肺腺癌細胞株,接種于裸鼠背部側翼至腋窩皮下,建立ABCE1-GFP肺腺癌動物模型。進行成瘤情況觀察,并予以倒置熒光顯微鏡系統(tǒng)呈像。取材后進行免疫組織化學檢測。結果:穩(wěn)轉細胞系皮下接種裸鼠后,全部成瘤,過表達組腫瘤體積大于空載體及對照組(P0.05)。過表達組腫瘤在熒光顯微鏡系統(tǒng)下可穩(wěn)定表達綠色熒光,成功構建了ABCE1-GFP(+)肺腺癌皮下成瘤的裸鼠動物模型。免疫組織化學檢測亦驗證這一模型的確立。結論:穩(wěn)定轉染LTEP-a-2肺腺癌細胞可以用來成功建立皮下ABCE1-GFP(+)肺腺癌成瘤模型,是較為理想研究ABCE1在非小細胞肺癌中的基因功能的動物模型。
[Abstract]:Objective: to establish the nude mice model of ABCE1-GFP() lung adenocarcinoma and to detect it by immunohistochemistry. To further explore ABCE1 as a target for the diagnosis and treatment of non-small cell lung cancer (NSCLC) methods: the recombinant plasmid p#en1# and the empty vector p#en2# of LTEP-a-2 lung adenocarcinoma cell line, which were constructed in previous experiments, were used for the diagnosis and treatment of NSCLC. The animal model of ABCE1-GFP lung adenocarcinoma was established by inoculating the dorsal flanking to axillary subcutaneous of nude mice. The fluorescence microscope system was inverted and the samples were taken for immunohistochemical examination. Results: after subcutaneous inoculation of the stable transformed cell line, all of them were tumorigenic. The tumor volume of the overexpression group was larger than that of the empty vector and the control group (P 0.05). The tumor in the overexpression group could express green fluorescence stably under the fluorescence microscope system. A nude mouse model of subcutaneous tumorigenesis of lung adenocarcinoma ABCE1-GFP() was successfully constructed, and the establishment of this model was also verified by immunohistochemistry. Conclusion: stable transfection of LTEP-a-2 can be used to successfully establish subcutaneous ABCE1-GFP (lung adenocarcinoma) tumorigenic model. It is an ideal animal model to study the gene function of ABCE1 in non-small cell lung cancer.
