Pancreatic adenocarcinoma (PAAD) is a prevalent and aggressive malignancy in the digestive tract, requiring accurate prediction and effective treatment strategies. Recently, the discovery of disulfidptosis, a novel form of programmed cell death characterized by abnormal disulfide accumulation, has sparked interest in its role in PAAD. In this study, we aimed to investigate the involvement of disulfidptosis-related genes (DRGs) in PAAD. Using publicly available databases, we conducted a comprehensive analysis exploring the complex relationships between DRGs and important aspects of PAAD, including gene expression, immune response, mutation, drug sensitivity, and functional enrichment. Notably, we observed significant heterogeneity among different disulfidptosis subclusters and identified specific differentially expressed genes in PAAD. Through machine learning techniques, we identified SLC7A11, S100A4, DIAPH3, PRDX1, and SLC7A7 as the most relevant hub genes. We further validated their significance in PAAD by considering their expression patterns, prognostic value, diagnostic potential, diagnostic model, and immune infiltration. This study presents exciting opportunities and challenges in unraveling the underlying mechanisms of PAAD prognosis. It also establishes a foundation for personalized cancer care and the development of innovative immunotherapeutic strategies. By shedding light on the role of DRGs, particularly hub genes, we enhance our understanding and management of PAAD.
胰腺腺癌(PAAD)是消化道中一种常见且侵袭性强的恶性肿瘤,需要准确的预测和有效的治疗策略。最近,二硫键凋亡这种以异常二硫键积累为特征的新型程序性细胞死亡形式的发现,引发了人们对其在PAAD中作用的兴趣。在本研究中,我们旨在探究二硫键凋亡相关基因(DRGs)在PAAD中的参与情况。利用公开可用的数据库,我们进行了全面分析,探讨DRGs与PAAD重要方面之间的复杂关系,包括基因表达、免疫反应、突变、药物敏感性和功能富集。值得注意的是,我们观察到不同二硫键凋亡亚群之间存在显著异质性,并在PAAD中鉴定出特定的差异表达基因。通过机器学习技术,我们确定溶质载体家族7成员11(SLC7A11)、S100钙结合蛋白A4(S100A4)、二氢嘧啶脱氢酶相关蛋白3(DIAPH3)、过氧化物酶1(PRDX1)和溶质载体家族7成员7(SLC7A7)为最相关的核心基因。我们通过考虑它们的表达模式、预后价值、诊断潜力、诊断模型和免疫浸润,进一步验证了它们在PAAD中的重要性。本研究为揭示PAAD预后的潜在机制带来了令人兴奋的机遇和挑战。它还为个性化癌症护理和创新免疫治疗策略的开发奠定了基础。通过阐明DRGs,特别是核心基因的作用,我们增进了对PAAD的理解和管理。
