组织蛋白酶 (CathepsinD ,CathD)为一种溶酶体酸性蛋白酶 ,具有刺激细胞生长、溶解基底膜、细胞外基质及结缔组织能力[1] 。近年发现CathD是评价肿瘤预后和生物学行为的重要标记物指标[2~ 7] 。作者应用ABC免疫组织化学法研究胃良、恶性病变组织Cat
CathepsinD (CathD) is a lysosomal acid protease that has the ability to stimulate cell growth, dissolve the basement membrane, extracellular matrix, and connective tissue [1]. In recent years, it has been found that CathD is an important marker for evaluating the prognosis and biological behavior of tumors [2-7]. The authors applied ABC immunohistochemistry to study the benign and malignant lesions of stomach
