小窝蛋白1及其磷酸化在食管鳞癌组织中的表达及其临床意义

Expression of caveolin-1 and PY14caveolin-1 and its clinical significance in esophageal squamous cell carcinoma

目的 检测小窝蛋白1(caveolin-1,Cav-1)及其磷酸化小窝蛋白1(PY 14caveolin-1)在不同食管组织中的表达,探讨Cav-1及其PY14cav-1与食管癌发生、发展的关系.方法 收集60例食管鳞状细胞癌患者手术标本,采用蛋白印迹法检测Cav-1及PY 14cav-1在食管癌组织、癌旁组织及正常食管组织中的表达情况,分析C av-1及PY14Cav-1表达水平与食管癌发生、发展的关系.结果 Cav-1及PY14cav-1在食管鳞癌组织中的表达水平明显高于癌旁组织与食管正常组织中的表达水平,差异均有统计学意义(P均＜0.05).结论 Cav-1及PY14cav-1在食管癌组织、癌旁组织及正常食管组织中的表达依次减少,提示其在食管癌的发生和发展过程中起着重要作用,而且可能参与食管癌的侵袭和转移.

Objective To detect the expression of caveolin-1 and PY14caveolin-1 in different esophageal tissues,and study the relationships between the expressions of caveolin-1 and PY14caveolin-1 with the occurrence and development of esophageal squamous cell carcinoma.Methods The fresh surgical specimens in 60 patients with esophageal squamous cell carcinoma were collected and Western blotting were used to analyze and detect the expressions of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma,adjacent esophageal tissues and normal esophageal tissues.The expression of cav-1 and PY14caveolin-1 with esophageal squamous cell carcinoma were analyzed.Results The expressions of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma were much higher than that in adjacent tissues and normal esophageal tissues,and the difference between them was statistically significant(P＜0.05).Conclusion The expression of caveolin-1 and PY14caveolin-1 in esophageal squamous cell carcinoma, adjacent esophageal tissues and normal esophageal tissues decreases successively,it suggests the caveolin-1 and PY14caveolin-1 may be the key of the occurrence and development of esophageal cancer cells and they could be involved in the migration and invasion of esophageal cancer.
