【摘要】：目的對rno-micro RNA-296-5p(mi R-296)靶基因預測并進行相關生物信息學分析,為深入研究mi R-296與胎肺發(fā)育相關的生物學功能提供理論依據(jù)。方法應用Pub Med、Google等信息搜索工具檢索mi R-296的現(xiàn)有研究,并通過mi RBase獲取其序列特征以及進化的保守性;利用Target Scan數(shù)據(jù)庫進行mi R-296的靶基因預測;并利用DAVID Bioinformatics Resources 6.8數(shù)據(jù)庫對靶基因進行功能富集分析;利用KEGG數(shù)據(jù)庫對靶基因進行信號轉導通路分析。結果已有的文獻表明mi R-296在許多生物學過程中發(fā)揮重要作用,序列在多物種間高度保守。mi R-296調控的靶基因參與分子功能、細胞組分和生物學過程等方面,靶基因集合的信號轉導通路顯著富集于MAPK信號通路、Wnt信號通路、TGF-β信號通路等(均P0.05)。結論通過對mi R-296靶基因的生物信息學分析,為研究mi R-296在肺發(fā)育中的作用提供了功能與機制的線索。
[Abstract]:Objective to predict the target gene of rno-micro RNA-296-5p(mi R-296 and analyze the related bioinformatics. To provide theoretical basis for the further study of biological function of miR-296 related to fetal lung development. Methods Pub Med was used. Google and other information search tools retrieve the existing research of mi R-296, and obtain its sequence characteristics and evolutionary conservatism by means of mi RBase. The target gene of miR-296 was predicted by Target Scan database. DAVID Bioinformatics Resources 6.8 database was used to analyze the functional enrichment of the target gene. KEGG database was used to analyze the signal transduction pathway of target gene. Results the results showed that miR-296 played an important role in many biological processes. The target genes regulated by .mi R-296 are involved in molecular function, cell composition and biological process. The signal transduction pathway of target gene assembly was significantly enriched in MAPK signaling pathway and Wnt signaling pathway. TGF- 尾 signaling pathway (P0.05). Conclusion the target gene of mi R-296 was analyzed by bioinformatics. It provides clues to the function and mechanism of miR-296 in lung development.
