摘要 目的 :探讨喉癌组织中抑癌基因 (WAF1 )的表达及其意义。方法 :采用 Western印迹杂交法。结果 :正常喉粘膜组织中有不同程度的 WAF1基因蛋白 p2 1的表达。 64例中有 47例 Western印迹杂交出条带 ,阳性表达率为 73.4%。喉癌组织中 p2 1也有表达 ,64例中有 33例 ,表达率为51 .5%。喉癌 p2 1阳性表达的 33例患者中 1 4例 p53表达阴性 ,但 p2 1无表达的 31例患者中仍有1 3例患者 p53表达阳性 ,且表达量较多。p2 1的表达与喉癌病理分级无关。结论 :p2 1蛋白在喉癌中的表达率低 ,p2 1蛋白表达障碍可能是喉癌发生、发展的重要机理。 p2 1蛋白表达不完全受 p53蛋白的诱导。
