The aim of the present study was to investigate the key genes, miRNAs and pathways in hypopharyngeal squamous cell carcinoma (HPSCC) and to elucidate the mechanisms underlying HPSCC development. The gene and microRNA (miRNA) expression profiles of HPSCC tissues and adjacent normal tissues from three subjects were obtained. Differentially expressed genes (DEGs) and differentially expressed miRNAs were identified in HPSCC. Functional annotation and protein‑protein interaction (PPI) network were conducted to elucidate the biological functions of DEGs. A total of 160 DEGs (16 upregulated and 144 downregulated genes) and 79 differentially expressed miRNAs (48 upregulated and 31 downregulated miRNAs) were identified in HPSCC. The deregulated genes were significantly involved in spliceosome, cell cycle and RNA degradation. In the PPI network, S‑phase kinase associated protein 1 (SKP1), non‑POU domain containing octamer binding (NONO) and zinc activated ion channel (ZACN) were identified as hub proteins. On the whole, the present study may help to gain a comprehensive understanding of tumorigenesis in HPSCC and provide valuable information for early diagnosis and drug design of HPSCC in future research.
本研究旨在探讨下咽鳞状细胞癌(HPSCC)中的关键基因、微小 RNA(miRNA)和途径,并阐明 HPSCC 发展的机制。本研究从三个受试者中获得了 HPSCC 组织和相邻正常组织的基因和 miRNA 表达谱。鉴定了 HPSCC 中的差异表达基因(DEGs)和差异表达 miRNA。对 DEGs 进行了功能注释和蛋白质-蛋白质相互作用(PPI)网络分析,以阐明 DEGs 的生物学功能。在 HPSCC 中鉴定出 160 个差异表达基因(16 个上调和 144 个下调基因)和 79 个差异表达 miRNA(48 个上调和 31 个下调 miRNA)。失调基因显著参与剪接体、细胞周期和 RNA 降解。在 PPI 网络中,鉴定出 S 期激酶相关蛋白 1(SKP1)、非 POUS 域包含八聚体结合(NONO)和锌激活离子通道(ZACN)作为枢纽蛋白。总的来说,本研究可能有助于全面了解 HPSCC 的肿瘤发生,并为未来研究中 HPSCC 的早期诊断和药物设计提供有价值的信息。
