Breast cancer (BC) is one of the most common malignancies in female, and has a high mortality rate. The mechanisms of tumorigenesis and reprogramming of somatic cells have a certain degree of similarity. Here, we focus on the relationship between gene expression, signaling pathways and functions in BC compared to induced pluripotent stem cells (iPSCs). We first identified differentially expressed genes (DEGs) common to BC and iPSCs in datasets from GEO and TCGA. We found 22 DEGs that were significantly associated with clinicopathological features and prognosis by performing Kaplan-Meier survival analysis and one-way ANOVA. The results of protein mass spectrometry of tumor stem cells (Mcfips) demonstrated that the proteins encoded by 8 of these DEGs were also differentially expressed. The functional enrichment analysis showed that most of the 30 DEGs were related to collagen and chromatin functions. Our results might offer targets for future studies into the mechanisms underlying tumor occurrence and progression, and our studies could provide valuable data for both basic research and clinical applications of BC.
乳腺癌(BC)是女性最常见的恶性肿瘤之一,死亡率很高。肿瘤发生和体细胞重编程的机制有一定程度的相似性。在这里,我们将重点关注与诱导多能干细胞(iPSCs)相比,BC 中基因表达、信号通路和功能之间的关系。我们首先从 GEO 和 TCGA 的数据集确定了与 BC 和 iPSCs 共有的差异表达基因(DEGs)。我们通过 Kaplan-Meier 生存分析和单向方差分析发现,22 个 DEG 与临床病理特征和预后显著相关。肿瘤干细胞(Mcfips)的蛋白质质谱结果表明,这 22 个 DEG 中编码的蛋白质也存在差异表达。功能富集分析表明,30 个 DEG 中的大多数与胶原和染色质功能有关。我们的结果可能为肿瘤发生和进展机制的未来研究提供靶点,我们的研究可以为 BC 的基础研究和临床应用提供有价值的数据。
