This study was conducted to elucidate the mitophagy-related differentially expressed genes (MRDEGs) in corneal endothelial dysfunction (CED) and to identify key hub genes that could provide insights into the disease pathogenesis and potential targeted therapies. To achieve this, CED models were established in female SD rats, and RNA sequencing of coronal endothelium samples was conducted to generate a self-testing dataset. Comprehensive bioinformatics analyses were executed, which included the identification of differentially expressed genes (DEGs), GO and KEGG enrichment analyses, GSEA, and GSVA. A protein-protein interaction (PPI) network was constructed to identify highly interconnected hub genes, followed by the construction of ROC curves to validate MRDEGs within the dataset, alongside qRT-PCR assays. Our findings revealed a total of 18,511 DEGs, among which 20 genes were characterized as MRDEGs. Enrichment analyses indicated significant associations with monocyte differentiation and lymphocyte proliferation. Importantly, eight hub genes emerged from the PPI network as promising therapeutic targets. In conclusion, this study underscores the important role of MRDEGs and immune infiltration in CED, laying the groundwork for future investigations into targeted therapies for this disease.
本研究旨在阐明角膜内皮功能障碍(CED)中与线粒体自噬相关的差异表达基因(MRDEGs),并确定关键的核心基因,为该疾病的发病机制和潜在的靶向治疗提供见解。为此,在雌性SD大鼠中建立了CED模型,并对冠状内皮样本进行RNA测序以生成一个自测数据集。进行了全面的生物信息学分析,包括差异表达基因(DEGs)的鉴定、GO和KEGG富集分析、GSEA和GSVA。构建了蛋白质-蛋白质相互作用(PPI)网络以识别高度互联的核心基因,随后构建ROC曲线以验证数据集中的MRDEGs,并进行qRT-PCR检测。我们的研究结果共揭示了18511个DEGs,其中20个基因被鉴定为MRDEGs。富集分析表明它们与单核细胞分化和淋巴细胞增殖显著相关。重要的是,从PPI网络中筛选出的8个核心基因有望成为治疗靶点。总之,本研究强调了MRDEGs和免疫浸润在CED中的重要作用,为该疾病未来的靶向治疗研究奠定了基础。
