摘要:

目的: 探讨毛细胞损伤过程中的基因表达、信号通路、生物学过程变化,为毛细胞再生及前庭功能重塑提供新的思路。方法: 采用RNA-seq方法研究新生小鼠椭圆囊在新霉素损伤后的基因表达变化及相关分子通路。结果: 新霉素处理样品中分别有172个和232个基因表达上调和下调。这些基因的GO和KEGG通路分析揭示了许多可能与毛细胞发育相关的细胞成分、分子功能、生物过程和信号通路。结论: 本研究的结果为未来的研究提供了有价值的参考和前期基础,并发现Wnt、Notch和TGFβ等信号通路可能与前庭毛细胞损伤及再生密切相关,可能为前庭毛细胞再生研究及临床眩晕防治提供重要信号通路和基因靶点。

Abstract:

AIM: Vestibular hair cell damage is an important cause of vestibular dysfunction. This study tried to explore the changes of gene expression, signal pathway and biological process in the process of hair cell damage, so as to provide new ideas for hair cell regeneration and vestibular function recovery. METHODS: In the present study, RNA from the newborn mouse utricles was collected for RNA-seq immediately after the damage of neomycin, in order to investigate gene expression changes. RESULTS:There were 172 and 232 genes that were found to be up-regulated and down-regulated in neomycin-treated utricles. GO and KEGG pathway analyses of these genes revealed many deregulated cellular components, molecular functions, biological processes and signaling pathways that may be related to hair cell development.CONCLUSION: These results provide valuable reference and preliminary basis for future studies, and find that Wnt, Notch TGFβ and other signaling pathways that may be closely related to vestibular hair cell injury and regeneration, which may provide important signaling pathways and gene targets for vestibular hair cell regeneration research and clinical vertigo prevention.
