摘要
[目的]研究不同级别的舌鳞状细胞癌中细胞周期蛋白A(cyclinA)基因和蛋白的表达及其意义。[方法]应用微波内免疫组化ABC法检测cyclinA蛋白及原位杂交技术检测cyclinAmRNA的表达情况。[结果〕免疫组化cyclinA多克隆抗体标记60.0%(18/30)显示cyclinA蛋白过度表达;cyclinA探针随机引物标记,经原位杂交后显示,cyclinAmRNA的阳性表达率为70.0%(21/30)。(结论]cyclinA在舌癌中有高水平的表达,且临床分期越晚,恶性程度越高,其表达率也较高,提示cyclinA的过度表达与舌癌的特性密切相关,cyclinA阳性检出率有助于判断舌癌恶性程度及预测肿瘤的转移,在舌癌的发生、发展中起着重要作用。
