The aim of this study was to analyse relationship between changes of the stroma and expression of tenascin-C (TN-C) and laminin in prostate carcinoma. Tenascin-C immunostaining was increased, and laminin decreased in carcinomas compared with peritumoral tissue and benign prostate hyperplasia (P<0.05). Statistical analysis confirmed connection between stromal changes and TN-C expression in prostate carcinoma (P<0.05). Gleason pattern 3 carcinomas showed more pronounced stromal reaction and TN-C expression compared with Gleason pattern 4 carcinomas (P<0.05). The main cells in prostate cancer stroma are myofibroblasts that are also responsible for tenascin production. Degradation of laminin was not connected with myofibroblastic stromal changes.
本研究的目的是分析前列腺癌中基质变化与肌腱蛋白-C(TN-C)和层粘连蛋白表达之间的关系。与肿瘤周围组织和良性前列腺增生相比,癌组织中肌腱蛋白-C免疫染色增加,而层粘连蛋白减少(P<0.05)。统计分析证实前列腺癌中基质变化与TN-C表达之间存在关联(P<0.05)。与Gleason 4级癌相比,Gleason 3级癌显示出更明显的基质反应和TN-C表达(P<0.05)。前列腺癌基质中的主要细胞是肌成纤维细胞,它们也负责肌腱蛋白的产生。层粘连蛋白的降解与肌成纤维细胞性基质变化无关。
