Ranking as the sixth commonest cancer, esophageal squamous cell carcinoma (ESCC) represents one of the leading causes of cancer death worldwide. One of the main reasons for the low survival of patients with esophageal cancer is its late diagnosis.
We used proteomics approach to analyze ESCC tissues with the aim of a better understanding of the malignant mechanism and searching candidate protein biomarkers for early diagnosis of esophageal cancer. The differential protein expression between cancerous and normal esophageal tissues was investigated by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). Then proteins were identified by matrix-assisted laser desorption/ ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF-MS) and MASCOT web based search engine.
We reported 4 differentially expressed proteins involved in the pathological process of esophageal cancer, such as annexinA1 (ANXA1), peroxiredoxin-2 (PRDX2), transgelin (TAGLN) andactin-aortic smooth muscle (ACTA2).
In this report we have introduced new potential biomarker (ACTA2). Moreover, our data confirmed some already known markers for EC in our region.
食管鳞状细胞癌(ESCC)是全球第六大常见癌症,也是全球癌症死亡的主要原因之一。食管癌患者生存率低的主要原因之一是其诊断较晚。
我们采用蛋白质组学方法分析ESCC组织,旨在更好地了解其恶性机制,并寻找用于食管癌早期诊断的候选蛋白质生物标志物。通过二维聚丙烯酰胺凝胶电泳(2D-PAGE)研究癌组织与正常食管组织之间的差异蛋白质表达。然后通过基质辅助激光解吸/电离串联飞行时间质谱(MALDI-TOF/TOF-MS)和基于MASCOT的网络搜索引擎鉴定蛋白质。
我们报告了4种参与食管癌病理过程的差异表达蛋白质,如膜联蛋白A1(ANXA1)、过氧化物酶还原蛋白2(PRDX2)、转胶蛋白(TAGLN)和肌动蛋白-主动脉平滑肌(ACTA2)。
在本报告中,我们介绍了新的潜在生物标志物(ACTA2)。此外,我们的数据证实了我们所在地区一些已知用于食管癌的标志物。
