Studying bladder cancer molecular biology revealed the presence of genetic alterations. So, detection of molecular biomarkers that help in monitoring the disease, evaluating the prognosis of the patients, and their response to therapy is needed. In this study, we investigated the expression and the prognostic significance of SATB-1 and ERBB2 mRNA and protein by quantitative RT-PCR and immunohistochemical analysis in urothelial bladder cancer cases and the surrounding normal bladder tissue. The correlations between the expression of both markers and the clinicopathological parameters were performed with further analysis of the correlation between the expression of SATB-1 and ERBB2. Compared to control, the expression of SATB-1 and ERBB2 mRNA and protein in cancer tissues were significantly up-regulated (p< 0.05). Also, a positive correlation between both markers was found (r= 0.53, p< 0.001). Moreover, elevated levels of both markers were significantly associated with the stage, lymph node involvement at both mRNA and protein levels (p< 0.001). In conclusion, there is a clinical significance of SATB-1 and ERBB2 as potential biomarkers for predicting bladder cancer patients of aggressive behavior and poor prognosis.
研究膀胱癌的分子生物学揭示了遗传改变的存在。因此,需要检测有助于监测疾病、评估患者预后及其对治疗反应的分子生物标志物。在这项研究中,我们通过定量 RT-PCR 和免疫组织化学分析研究了 SATB-1 和 ERBB2 mRNA 和蛋白质在尿路上皮膀胱癌病例及其周围正常膀胱组织中的表达及其预后意义。通过进一步分析 SATB-1 和 ERBB2 之间的表达相关性,对这两种标志物的表达与临床病理参数之间的相关性进行了分析。与对照相比,癌症组织中 SATB-1 和 ERBB2 mRNA 和蛋白质的表达显著上调(p<0.05)。此外,还发现这两种标志物之间存在正相关(r=0.53,p<0.001)。此外,两种标志物水平升高均与肿瘤分期、淋巴结受累相关(mRNA 和蛋白水平均 p<0.001)。总之,SATB-1 和 ERBB2 作为潜在的生物标志物,对预测具有侵袭性行为和不良预后的膀胱癌患者具有临床意义。
