Clear cell renal cell carcinoma (ccRCC) is characterized by the inactivation of the von Hippel-Lindau () gene. Of note, no other gene is mutated as frequently as in ccRCC, turning out that patients with inactivated constitute the majority of ccRCC-related character. Thus, differentially expressed genes (DEGs) and their molecular networks caused by mutation were considered as important factors for influencing the prognosis of ccRCC. Here, we first screened out six DEGs (, , , , , and ) which downregulated in ccRCC patients with non-mutation than with the mutation. Generally, most DEGs with high expression were associated with a favorable prognosis and low-risk score. Meanwhile, we spotted transcription factors and their kinases as hubs of DEGs. Finally, we clustered ccRCC patients into three subgroups according to the expression of hub proteins, and analyzed these subgroups with clinical profile, outcome, immune infiltration, and potential Immune checkpoint blockade (ICB) response. Herein, DEGs might be a promising biomarker panel for immunotherapy and prognosis in ccRCC. Moreover, the ccRCC subtype associated with high expression of hubs fit better for ICB therapy.
透明细胞肾细胞癌(ccRCC)的特征是von Hippel-Lindau(VHL)基因失活。值得注意的是,在ccRCC中没有其他基因像VHL那样频繁发生突变,结果表明VHL基因失活的患者构成了ccRCC相关特征的大多数。因此,由VHL突变引起的差异表达基因(DEGs)及其分子网络被认为是影响ccRCC预后的重要因素。在此,我们首先筛选出六个DEGs(……此处原文六个基因名称未完整给出,无法准确翻译……),这些基因在VHL非突变的ccRCC患者中比在VHL突变的患者中表达下调。一般来说,大多数高表达的DEGs与良好的预后和低风险评分相关。同时,我们发现转录因子及其激酶是DEGs的枢纽。最后,我们根据枢纽蛋白的表达将ccRCC患者分为三个亚组,并对这些亚组的临床特征、预后、免疫浸润和潜在的免疫检查点阻断(ICB)反应进行了分析。在此,DEGs可能是ccRCC免疫治疗和预后的一个有前景的生物标志物面板。此外,与枢纽高表达相关的ccRCC亚型更适合ICB治疗。
