Sci Rep:不同格林森评分前列腺癌中类固醇激素受体和基质细胞标记表达比较

2018-10-11 AlexYang MedSci原创

抗血管生成和免疫调节药物最近的发展表明了肿瘤微环境(TME)在癌症研究中越来越重要。最近,有研究人员通过比较不同GS组中类固醇激素受体的组织表达情况、癌症激活成纤维细胞(CAF)标记和血管密度情况,调查了格林森评分(GS)与TME之间的相关性。匹配的患者群体组成了不同的GS分组(6-7-8)。研究人员利用6个样本/患者的组织芯片进行免疫组化染色。研究人员对染色的片子进行数字化,并对基质和上皮进行选

血管生成和免疫调节药物最近的发展表明了肿瘤微环境(TME)在癌症研究中越来越重要。

最近,有研究人员通过比较不同GS组中类固醇激素受体的组织表达情况、癌症激活成纤维细胞(CAF)标记和血管密度情况,调查了格林森评分(GS)与TME之间的相关性。匹配的患者群体组成了不同的GS分组(6-7-8)。研究人员利用6个样本/患者的组织芯片进行免疫组化染色。研究人员对染色的片子进行数字化,并对基质和上皮进行选择性的标注,还对所有选择的区域标记的表达进行定量的分析。研究发现,与低GS前列腺癌和配对的前列腺癌非肿瘤组织相比,一些激素诱导的受体的表达在基质中减少,CAF表型和血管密度在高GS前列腺癌中均增加。

最后,研究人员指出,他们的研究阐释了前列腺癌分化和TME组分之间的复杂联系,表明了不同的GS与TME中不同的作用靶标相关。标准化的数字成像分析工具的使用产生了大量的可重复的定量数据,与经典的半定量和依赖观察的免疫组化相比,是一种新的和有效信息更多的技术。
