摘要 目的 探讨IGF - 1R在前列腺腺癌和前列腺增生组织中的分布及其细胞生物学意义。方法 采用免疫组织化学技术ABC方法 ,对 2 3例前列腺腺癌和 15例前列腺增生组织中IGF - 1R的表达情况进行了检测分析。结果 前列腺腺癌组织和前列腺增生组织中IGF - 1R表达均呈阳性 ,IGF - 1R主要分布于前列腺上皮细胞膜 ,基质细胞中亦有散在、少量的分布 ;半定量分析结果显示 ,前列腺增生组织中IGF -1R表达 (或染色 )强度高于前列腺癌组织 ;ICF - 1R表达强度与前腺癌细胞分级呈负相关趋势 ,肿瘤细胞分级越高 (或分化越差 )IGF - 1R表达越弱。结论 研究提示 ,IGF - 1R (或IGFs系统 )在前列腺上皮细胞转化和肿瘤细胞增殖分化过程中具有一定作用。 Objective To study the distrobution and expression of IGF-1R in benign prostatic hyperplasia(BPh)and prostate cancer tisues and its cellular implicates.Methods Immunohistochemistry was performed to compare the expression of IGF-1R in 23 prostate cancer and 15BPH tissues.Results The results showed that IGF-1R mainly localized to the membrane of epithelial cells,Semiquantitative analysis suggested that the immunoreactivity of IGF-1R in prostate cancer was negatively to the grade of cancer cells.Conclusion This study suggested that IGF-1R might affect the proliferation and differdntiation of prostate cancer cells.
