Malignant pleural mesothelioma (MPM) is a rare cancer originated from pleural mesothelial cells. MPM has been associated with long-term exposure to asbestos. In this work we performed a comparative proteomic analysis of biphasic pleural mesothelioma (B-PM). Tissue biopsies were obtained from 61 patients who were subjected to a diagnostic thoracoscopy. 2D/MS based approach was used for proteomic analysis. The 22 proteins found differentially expressed in B-PM, with respect to benign, were analyzed by Ingenuity Pathways Analysis and compared with those obtained for epitheliod pleural mesothelioma (E-PM). A different activation of transcription factors, proteins and cytokines were observed between two subtypes.
恶性胸膜间皮瘤（MPM）是一种起源于胸膜间皮细胞的罕见癌症。MPM与长期接触石棉有关。在这项工作中，我们对双相性胸膜间皮瘤（B-PM）进行了比较蛋白质组学分析。从61例行诊断性胸腔镜检查的患者中获取组织活检样本。基于二维质谱的方法用于蛋白质组学分析。通过Ingenuity Pathways Analysis对在B-PM中相对于良性病变发现差异表达的22种蛋白质进行分析，并与上皮样胸膜间皮瘤（E-PM）所获得的蛋白质进行比较。在两种亚型之间观察到转录因子、蛋白质和细胞因子的不同激活情况。
