背景:角化,作为调节细胞死亡的独特方式,需要泛素结合酶UBE2D2的参与。然而,UBE2D2在泛癌症中的预后和免疫治疗价值仍不清楚.
方法:使用UCSCXena,TIMER,临床蛋白质组学肿瘤分析联盟(CPTAC),和人类蛋白质图谱(HPA)数据库,我们旨在探讨UBE2D2在多种癌症类型中的差异表达模式,并评估其与患者预后的关系。临床特征,和遗传变异。通过基因集富集分析评估UBE2D2与免疫治疗反应之间的关联。肿瘤微环境,免疫基因共表达和药物半最大抑制浓度(IC50)分析。
结果:在大多数癌症类型中,UBE2D2的mRNA和蛋白水平显著升高,UBE2D2在肝细胞肝癌(LIHC)中显示出预后意义,肾发色(KICH),葡萄膜黑色素瘤(UVM),宫颈鳞状细胞癌和宫颈腺癌(CESC),肾乳头状细胞癌(KIRP)。UBE2D2表达与临床特征相关,肿瘤突变负荷,微卫星不稳定,以及几种肿瘤类型的抗肿瘤药物耐药性。基因富集分析表明UBE2D2与免疫相关通路显著相关。UBE2D2的表达水平与免疫细胞浸润有关,包括CD4+T细胞、巨噬细胞M2、CD8+T细胞。PDCD1、CD274和CTLA4表达水平与多种癌症中UBE2D2水平呈正相关。
结论:我们全面研究了UBE2D2作为泛癌症预后和免疫治疗预测因子的潜在价值,为癌症免疫治疗提供了新的见解。
BACKGROUND: Cuproptosis, as a unique modality of regulated cell death, requires the involvement of ubiquitin-binding enzyme UBE2D2. However, the prognostic and immunotherapeutic values of UBE2D2 in pan-cancer remain largely unknown.
METHODS: Using UCSC Xena, TIMER, Clinical Proteomic Tumor Analysis Consortium (CPTAC), and Human Protein Atlas (HPA) databases, we aimed to explore the differential expression pattern of UBE2D2 across multiple cancer types and to evaluate its association with patient prognosis, clinical features, and genetic variations. The association between UBE2D2 and immunotherapy response was assessed by gene set enrichment analysis, tumor microenvironment, immune gene co-expression and drug half maximal inhibitory concentration (IC50) analysis.
RESULTS: The mRNA and protein levels of UBE2D2 were markedly elevated in most cancer types, and UBE2D2 exhibited prognostic significance in liver hepatocellular carcinoma (LIHC), kidney chromophobe (KICH), uveal melanomas (UVM), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), and kidney renal papillary cell carcinoma (KIRP). UBE2D2 expression was correlated with clinical features, tumor mutation burden, microsatellite instability, and anti-tumor drug resistance in several tumor types. Gene enrichment analysis showed that UBE2D2 was significantly associated with immune-related pathways. The expression level of UBE2D2 was correlated with immune cell infiltration, including CD4 + T cells、Macrophages M2、CD8 + T cells in pan-cancer. PDCD1, CD274 and CTLA4 expression levels were positively correlated with UBE2D2 level in multiple cancers.
CONCLUSIONS: We comprehensively investigated the potential value of UBE2D2 as a prognostic and immunotherapeutic predictor for pan-cancer, providing a novel insight for cancer immunotherapy.
