celbB－3基因位于12号染色体长臂，其蛋白质产物分子量为ledKD。目前，对C－ethB—3产物的功能不十分明确，亦未见到在胃癌方面的详细报道。我们应用免疫组化技术检测c—e巾B—3编码蛋白在胃癌中的表达，探讨其表达规律及其作用。材料与方法一、材料：59例胃癌标本均取自我院19 The celbB-3 gene is located on the long arm of chromosome 12, and its protein product molecular weight is ledKD. At present, the function of the C-ethB-3 product is not very clear and no detailed report on gastric cancer has been found. We used immunohistochemistry to detect the expression of the c-e-skin B-3 protein in gastric cancer, and to explore its expression pattern and its role. Materials and Methods I. Materials: 59 cases of gastric cancer specimens were taken from the hospital 19
