In RNA-seq data analysis, condensing the gene count matrix size is pivotal for downstream investigations, particularly pathway analysis. For this purpose, harnessing machine learning attracts increasing interest, while conventional methodologies depend on -value comparisons. In this study, 20 tissue samples from real-world cervical cancers were subjected to sequencing, followed by the application of the Mclust algorithm to delineate an optimal cluster. By stratifying tumor budding into high and low groups and quantifying the epithelial-to-mesenchymal transition (EMT) score to scrutinize tumor budding, we discerned 24 EMT-related genes, with 5 showing strong associations with cervical cancer prognosis. Our observations elucidate a biological flow wherein EMT, Matrix Metallopep-tidase 2 (MMP2), and extracellular matrix (ECM) degradation are interconnected, ultimately leading to collagen type VI and exacerbating the prognosis of cervical cancer. The present study underscores an alternative method for selecting useful EMT-related genes by employing an appropriate clustering algorithm, thereby avoiding classical methods while unveiling novel insights into cervical cancer etiology and prognosis. Moreover, when comparing high and low tumor budding, collagen type VI emerges as a potential gene marker for the prognosis of cervical cancer.
在RNA测序数据分析中,压缩基因计数矩阵的大小对于下游研究(尤其是通路分析)至关重要。为此,利用机器学习引起了越来越多的关注,而传统方法依赖于p值比较。在本研究中,对来自真实世界宫颈癌的20个组织样本进行测序,随后应用Mclust算法来确定最佳聚类。通过将肿瘤芽生分为高分组和低分组,并量化上皮-间质转化(EMT)评分以检查肿瘤芽生,我们识别出24个与EMT相关的基因,其中5个与宫颈癌预后密切相关。我们的观察结果阐明了一种生物学流程,即EMT、基质金属肽酶2(MMP2)和细胞外基质(ECM)降解相互关联,最终导致VI型胶原蛋白生成并恶化宫颈癌的预后。本研究强调了一种通过采用适当的聚类算法来选择有用的EMT相关基因的替代方法,从而在揭示宫颈癌病因和预后的新见解的同时避免了经典方法。此外,在比较高肿瘤芽生和低肿瘤芽生时,VI型胶原蛋白成为宫颈癌预后的潜在基因标志物。
