摘 要:[目的] 运用血清蛋白质组分析技术(SERPA)鉴定非小细胞肺癌(NSCLC)的肿瘤相关抗原。[方法] 提取NSCLC肿瘤组织的胞浆蛋白,经二维凝胶电泳分离后转膜,用患者或健康对照血清为一抗进行免疫印迹分析,比较免疫印迹的结果,在未转膜的参比凝胶上找到差异蛋白点,进行MALDI-TOF鉴定;用免疫组化方法验证NSCLC组织中候选抗原的表达。[结果] 本研究共鉴定4个候选蛋白。CCT5在肺鳞癌和肺腺癌组织中表达明显升高,且主要定位于癌细胞浆,胞核未检测到表达。[结论] CCT5可能是NSCLC的肿瘤相关抗原。 |

Abstract:[Purpose] To identify novel tumor associated antigens from tissues of non-small cell lung cancer (NSCLC) using a modified proteomics-based approach. [Methods] Cytosol proteins extracted from tumor tissues were separated by mini-two-dimensional electrophoresis,followed by Western blot and hybridization with individual sera to determine serum antibody binding. Positive spots were excised from Coomassie blue-stained gels and the tryptic peptides were analyzed by matrix-assisted laser disorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). [Results] Total 4 proteins were identified in this study. The chaperonin containing TCP1 subunit 5 (CCT5) was expressed significantly higher in squamous cell lung carcinoma and lung adenocarcinoma than that in paracarcinomatous normal tissue. IHC results showed that there was no expression in cell nucleus. [Conclusion] The preliminary results suggest that CCT5 might be a novel tumor associated antigen. |
