BACKGROUND
We aimed to find different proteins between dendritic cells (DCs) and tumor antigen-pulsed DCs to help find a new biomarker for endometrial cancer (EC).
METHODS
Mononuclear cells were isolated from cord blood and induced to DCs by cytokines. A comparative proteomic analysis was performed on DCs and tumor lysate-pulsed DCs by liquid chromatography with tandem mass spectrometry (LC-MS/MS). Differential proteins were identified by Western blot analysis.
RESULTS
The expression of Ras-related protein Rab-8A (RAB8A) was found to be different in the in two kinds of cells. This phenomenon was also proven in endometrial cancer tissues.
CONCLUSIONS
RAB8A might be a new biomarker for endometrial cancer. Using LC-MS/MS to perform a comparative proteomic analysis about DCs and tumor lysate-pulsed DCs may help us to find new biomarker of cancer.
背景
我们旨在找出树突状细胞（DCs）与肿瘤抗原脉冲DCs之间的差异蛋白质，以帮助寻找子宫内膜癌（EC）的新型生物标志物。
方法
从脐带血中分离出单核细胞，并用细胞因子将其诱导为DCs。通过液相色谱串联质谱法（LC-MS/MS）对DCs和肿瘤裂解物脉冲DCs进行比较蛋白质组学分析。通过蛋白质免疫印迹分析鉴定差异蛋白质。
结果
发现Ras相关蛋白Rab-8A（RAB8A）在两种细胞中的表达存在差异。这种现象在子宫内膜癌组织中也得到了证实。
结论
RAB8A可能是子宫内膜癌的新型生物标志物。利用LC-MS/MS对DCs和肿瘤裂解物脉冲DCs进行比较蛋白质组学分析可能有助于我们找到癌症新的生物标志物。
