Keyword:  角质形成细胞抗体抗角蛋白角蛋白酪氨酸磷酸化p38丝裂原活化的蛋白激酶;
Abstract: 目的:研究抗角蛋白抗体对角蛋白及p38丝裂原活化的蛋白激酶(MAPK)磷酸化的影响.方法:提取抗体作用过的人舌鳞状细胞癌(Tca)细胞角蛋白,以未经抗体作用的细胞作阴性对照.角蛋白经十二烷基磺酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)分离、转膜,用抗酪氨酸磷酸化抗体作用和显色.超声裂解抗体作用细胞,设置阴性对照.经SDS-PAGE分离、转膜后用抗磷酸化p38MAPK抗体作用,化学发光剂发光显影.结果:角蛋白在分子质量大约为58 ku处出现阳性条带;阴性对照未出现条带.抗磷酸化p38MAPK抗体作用后在分子质量大约44ku处有阳性条带;阴性对照在相应处未出现条带.结论:角蛋白及p38 MAPK磷酸化是Tca细胞增殖抑制的重要调控方式.
