Bladder cancer (BC) is one of the most often reported malignancies globally, with a high recurrence rate and associated morbidity and mortality, especially in advanced BC. There has been a surge in the number of molecular targets revealed for BC prognosis and treatment. However, there is still a great need to discover novel biomarkers. Consequently, the current study investigated biomarkers that might indicate the progression of bladder cancer. In this study, bioinformatics analysis was done on a single GEO dataset, and TCGA-BLCA information was connected with differentially expressed genes (DEGs). The levels of mRNA and protein expression were validated using qRT-PCR. According to our findings, CRYAB, ECM1, ALDOB, AOC, GPX3, IGFBP7, AQP2, LASS2, TMEM176A, GALNT1, and LASS2 were highly enriched in cell division, identical protein binding, and developmental process in bladder cancer patients. In addition, among the highly differentiated genes, ECM1, GALNT1, LASS2, and GPX3 showed significant molecular alterations in BC, which are crucial for marker identification. Moreover, the mRNA, CNVs, and protein levels of ECM1, GALNT1, LASS2, and GPX3 were significantly increased in BC patients. Our predictions and analysis studies stated that these four genes act as urine biomarkers and played a crucial role in disease prognosis and the therapeutic process of bladder cancer. Our outcomes showed that these four novel urine biomarkers have the potential to provide innovative diagnostics, early predictions, and disease targets, ultimately improving the BC patient's prognosis.
膀胱癌 (BC) 是全球报告最多的恶性肿瘤之一,具有高复发率和相关发病率及死亡率,尤其是在晚期 BC 中。已经有大量的分子靶点被揭示出来用于 BC 的预后和治疗。然而,仍然需要发现新的生物标志物。因此,本研究探讨了可能预示膀胱癌进展的生物标志物。在这项研究中,对单个 GEO 数据集进行了生物信息学分析,并将 TCGA-BLCA 信息与差异表达基因 (DEGs) 连接起来。使用 qRT-PCR 验证了 mRNA 和蛋白表达水平。根据我们的发现,CRYAB、ECM1、ALDOB、AOC、GPX3、IGFBP7、AQP2、LASS2、TMEM176A、GALNT1 和 LASS2 在膀胱癌患者中高度富集于细胞分裂、相同蛋白结合和发育过程。此外,在高度分化的基因中,ECM1、GALNT1、LASS2 和 GPX3 在 BC 中表现出显著的分子改变,这对于标志物的识别至关重要。此外,ECM1、GALNT1、LASS2 和 GPX3 的 mRNA、CNVs 和蛋白水平在 BC 患者中显著升高。我们的预测和分析研究表明,这四个基因作为尿液生物标志物,在疾病预后和膀胱癌的治疗过程中发挥着关键作用。我们的研究结果表明,这四个新型尿液生物标志物具有提供创新诊断、早期预测和疾病靶点的潜力,最终改善 BC 患者的预后。
