Replication Factor C Subunit 4 (RFC4), an oncogene implicated in many human cancers, has yet to be extensively studied in many cancer types to determine its expression patterns and tumor tissue function. Various bioinformatics tools were used to analyze RFC4 as a potential oncogene and therapeutic target across many cancers. We first examined RFC4 expression levels in several human tumor types to determine relationships with tumor grade, stage, metastasis, and patient survival. We also examined RFC4's genetic changes, epigenetic methylation, and effect on tumor microenvironment (TME) immune cell infiltration. We also analyzed RFC4's connections with immunological checkpoints to identify potential molecular pathways involved in carcinogenesis. Our findings show that RFC4 is upregulated in several tumor types and associated with poor prognoses in many human cancers. This study shows that RFC4 significantly affects the tumor immunological microenvironment, specifically immune cell populations. Finally, we screened for RFC4-inhibiting pharmacological compounds with anti-cancer potential. This study fully elucidates RFC4's carcinogenic activities, emphasizing its potential as a prognostic biomarker and a target for anti-cancer therapy.
复制因子C亚基4(RFC4)是一种与多种人类癌症相关的癌基因,但在许多癌症类型中尚未得到广泛研究,以确定其表达模式和肿瘤组织功能。我们使用了各种生物信息学工具来分析RFC4作为多种癌症中的潜在癌基因和治疗靶点。我们首先检测了几种人类肿瘤类型中RFC4的表达水平,以确定其与肿瘤分级、分期、转移和患者生存率的关系。我们还研究了RFC4的基因变化、表观遗传甲基化及其对肿瘤微环境(TME)免疫细胞浸润的影响。我们还分析了RFC4与免疫检查点的联系,以确定参与致癌过程的潜在分子途径。我们的研究结果表明,RFC4在几种肿瘤类型中上调,并且与许多人类癌症的不良预后相关。这项研究表明,RFC4显著影响肿瘤免疫微环境,特别是免疫细胞群体。最后,我们筛选了具有抗癌潜力的RFC4抑制性药理化合物。这项研究充分阐明了RFC4的致癌活性,强调了其作为预后生物标志物和抗癌治疗靶点的潜力。
