Microchromosome maintenance (MCM) proteins are a number of nuclear proteins with significant roles in the development of cancer by influencing the process of cellular DNA replication. Of the MCM protein family, MCM10 is a crucial member that maintains the stability and extension of DNA replication forks during DNA replication and is significantly overexpressed in a variety of cancer tissues, regulating the biological behaviour of cancer cells. But little is understood about MCM10's functional role and regulatory mechanisms in a range of malignancies. We investigate the impact of MCM10 in human cancers by analyzing data from databases like the Gene Expression Profiling Interaction Analysis (GEPIA2), Genotype-Tissue Expression (GTEx) and The Cancer Genome Atlas (TCGA), among others. Possible relationships between MCM10 and clinical staging, diagnosis, prognosis, Mutation burden (TMB), microsatellite instability (MSI), immunological checkpoints, DNA methylation, and tumor stemness were identified. The findings demonstrated that MCM10 expression was elevated in the majority of cancer types and was connected to tumor dryness, immunocytic infiltration, immunological checkpoints, TMB and MSI. Functional enrichment analysis in multiple tumors also identified possible pathways of MCM10 involvement in tumorigenesis. We also discovered promising MCM10-targeting chemotherapeutic drugs. In conclusion, MCM10 may be a desirable pan-cancer biomarker and offer fresh perspectives on cancer therapy.
微染色体维持(MCM)蛋白是一组核蛋白,在癌症的发展中具有重要作用,通过影响细胞 DNA 复制过程。在 MCM 蛋白家族中,MCM10 是一个关键成员,在 DNA 复制过程中维持 DNA 复制叉的稳定性和延伸,并且在多种癌症组织中过度表达,调节癌细胞的生物学行为。但是,关于 MCM10 在多种恶性肿瘤中的功能作用和调节机制还知之甚少。我们通过分析基因表达谱交互分析(GEPIA2)、基因型组织表达(GTEx)和癌症基因组图谱(TCGA)等数据库中的数据来研究 MCM10 在人类癌症中的影响。鉴定了 MCM10 与临床分期、诊断、预后、突变负担(TMB)、微卫星不稳定性(MSI)、免疫检查点、DNA 甲基化和肿瘤干性之间的可能关系。研究结果表明,MCM10 在大多数癌症类型中表达上调,与肿瘤干性、免疫细胞浸润、免疫检查点、TMB 和 MSI 相关。在多种肿瘤中的功能富集分析也鉴定了 MCM10 参与肿瘤发生的可能途径。我们还发现了有前途的针对 MCM10 的化疗药物。总之,MCM10 可能是一种理想的泛癌生物标志物,并为癌症治疗提供了新的视角。
