摘要:

目的 使用RNA-seq技术分析腺苷脱氨酶1(ADAR1)在宫颈癌Hela细胞株中对基因表达的调控情况,并为揭示ADAR1在宫颈癌发生和进展中的作用提供理论依据。 方法 对正常和ADAR1敲低的Hela细胞株进行RNA-seq测序,筛选出差异表达基因。通过KEGG Pathway、GO cellular和GSEA富集分析,分析ADAR1在Hela细胞株中参与的相关信号通路和生物学过程。 结果 差异表达基因主要富集在免疫和炎症相关信号通路(如TNF-α/NF-κB、NIK/NF-κB、Jak/Stat-IL-6)、Hippo信号通路、TGF-β等信号通路上,参与了干扰素应答、细胞氨基酸代谢调控、蛋白质泛素化/去泛素化、病毒转录等生物过程;对NF-κB信号通路的相关基因进行深入分析后发现,ADAR1敲低后,NF-κB1和TRAF5的mRNA表达水平明显升高(P < 0.05)。 结论 ADAR1可能通过调控NF-κB信号通路相关因子的表达,进而调控宫颈癌的发生和发展。

Abstract:

Objective To analyze the regulation of gene expression by adenosine deaminase RNA specific 1(ADAR1) in cervical cancer cell line Hela using RNA-seq technology and provide theoretical basis for understanding the role of ADAR1 in the occurrence and progression of cervical cancer. Methods RNA-seq sequencing of normal and ADAR1 knockdown Hela cell lines to identify differentially expressed genes. By conducting enrichment analysis using KEGG Pathway, GO cellular, and GSEA, the study analyzes the relevant signaling pathways and biological processes involving ADAR1 in Hela cell lines. Results Differentially expressed genes are mainly enriched in immune and inflammation-related signaling pathways (such as TNF-α/NF-κB, NIK/NF-κB, Jak/Stat-IL-6), Hippo signaling pathway, TGF-β signaling pathway, and are involved in interferon response, cellular amino acid metabolism regulation, protein ubiquitination/deubiquitination, viral transcription, and other biological processes. Further analysis of the NF-κB signaling pathway revealed a significant increase in the mRNA expression levels of NF-κB1 and TRAF5 after ADAR1 knockdown. Conclusion ADAR1 may regulate the expression of NF-κB signaling pathway-related factors and thereby regulate the occurrence and development of cervical cancer.
