摘要

研究背景裸鼠被广泛用于研究长期慢性紫外线照射引起的光老化。循环 RNAs(circRNAs)已在多种疾病中被发现。然而,circRNAs在光老化中的作用及潜在调控机制仍不清楚:材料与方法:在本研究中,我们筛选了微阵列数据来分析 circRNAs 的表达。通过基因本体(GO)和京都基因和基因组百科全书(KEGG)生物通路对 circRNAs 进行了分析:结果:36个circRNA在紫外线组和对照组之间存在差异表达(折叠变化>1.5;P<0.05),包括6个上调的circRNA和30个下调的circRNA。GO和KEGG生物通路分析表明,circRNAs的变化与癌症、炎症、氧化应激和新陈代谢有关:本研究揭示了体内 circRNAs 的表达谱。这些发现不仅为预防光老化的发生提供了新的可能性,而且对光老化及相关皮肤疾病也有治疗价值。

Research on Circular RNA Expression Profiles in the Photoaging Mouse Model.

Background: Nude mouse has been widely used to study photoaging induced by long-term chronic UV exposure. Circular RNAs (circRNAs) have been previously identified in several diseases. However, the roles of circRNAs in photoaging and potential regulatory mechanisms remain unclear.

Objectives: To identify specific circRNAs differentially expressed in photoaged skin and investigate their potential role in aging.

Materials and methods: In this study, we screened out the microarray data to profile the expression of circRNAs. The circRNAs were analyzed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) biological pathway.

Results: 36 circRNAs were identified to be differentially expressed between the UV group and control group (fold change > 1.5; P < 0.05), including 6 upregulated and 30 downregulated circRNAs. GO and KEGG biological pathway analyses indicated that the changes in circRNAs were associated with cancer, inflammation, oxidative stress, and metabolism.

Conclusions: This present study revealed a circRNAs expression profiling in vivo. These findings not only provide a new possibility to prevent the occurrence of photoaging but also have therapeutic values for photoaging and associated skin diseases.
