目的 通过生物信息学方法对肺腺癌患者的基因表达谱芯片进行分析,研究影响肺腺癌的发展机制,探索肺腺癌新的治疗靶点.方法 从癌症基因图谱数据库下载mRNA和miRNA表达数据,通过R语言和生存分析筛选关键基因并通过数据库生存模块进行验证,对预后相关基因进行高表达通路富集分析.最后进行关键基因与免疫细胞相关性分析.结果 经筛选确定关键双硫死亡基因SLC3A2 和关键核激活miRNA(hsa-miR-1293),SLC3A2 与hsa-miR-1293 表达呈正相关,其表达越高,肺腺癌患者预后越差.与 SLC3A2 最显著相关的富集通路为氨酰基转移 RNA 生物合成.SLC3A2与 4 种差异免疫细胞呈正相关,与 4 种差异免疫细胞呈负相关.结论 hsa-miR-1293 正向调控双硫死亡基因SLC3A2 表达促进肺腺癌的发生发展,可为肺腺癌开发新的治疗靶点提供思路.
Hsa-miR-1293 positively regulates SLC3A2,a disulfide death gene and promotes the development of lung adenocarcinoma
Objective To analyse the gene expression profile microarrays of lung adenocarcinoma patients by bioinformatics methods,to study the mechanisms affecting the development of lung adenocarcinoma,and to explore new therapeutic targets for lung adenocarcinoma.Methods The mRNA and miRNA expression data were downloaded from The Cancer Genome Atlas database,key genes were screened by R language and survival analysis and verified by the survival module of the database,and high-expression pathway enrichment analysis was performed for prognostic related genes.Finally,the correlation between key genes and immune cells was analyzed.Results The key disulfide death gene SLC3A2 and key nuclear activation miRNA(hsa-miR-1293)were identified by screening.SLC3A2 was positively correlated with hsa-miR-1293,and the higher the expression,the worse the prognosis of lung adenocarcinoma patients.The most relevant enrichment pathway for SLC3A2 is aminoacyl transfer RNA biosynthesis.SLC3A2 was positively correlated with 4 kinds of differential immune cells and negatively correlated with 4 kinds of differential immune cells.Conclusion Hsa-miR-1293 positively regulates the expression of SLC3A2,a disulfide death gene,to promote the occurrence and development of lung adenocarcinoma,which may provide ideas for developing new therapeutic targets for lung adenocarcinoma.
