摘要: 目的 分析糖皮质激素受体(GR)靶基因在人类基因组的分布及功能,明确其生物学意义;方法 通过生物信息学的方法,在人类基因组中找出所有含有糖皮质激素反应元件(GRE)保守序列的基因。通过NCBI的基因注释得到基因名称、功能、基因的蛋白产物,以及其对应的GO号等,然后对这些基因的功能进行Gene Ontology(GO)分类,最后重点分析这些基因在免疫、炎症反应中的作用。结果 含有GRE-1保守序列(5'-AGAACAnnnTGTTCT-3')的基因共有225个,其中有18个位于基因启动子区域,10个位于基因外显子区域,197个位于内含子区域;含有GRE-2保守序列(5'-GGTACAnnnTGTTCT-3')的基因有94个,其中有13个位于基因启动子区域,5个位于基因外显子区域,76个位于内含子区域;结论 含有GRE的基因中F2R,DAXX,PAG1,ULBP3,OR8D4,RIMS1, NPY2R与激素代谢、免疫以及应激响应相关。

Abstract: Objective To identify the distribution and function of glucocoiticoid receptor (GR) regulated target genes in the human genome, and to know the bioinformatic significance of it. Methods: With bioinformatics methods, we found out all the genes that contains Glucocorticoid Response Element's (GRE) consensus sequences, and extend our study to the distribution of consensus sequences in the human genome and the functions , protein products and the Gene Ontology (GO) number of the GR target genes and then to emphasize these genes' function in inflammation and immunity. Results: We found 225 genes which contain the GRE-1 consensus sequence (5'-AGAACAnnnTGTTCT-3') and 94 genes contain GRE-2 consensus sequence (5'-GGTACAnnnTGTTCT-3'). Conclusion: According to the analysis of the function of genes which contain the consensus sequence of GRE, F2R, DAXX, PAG1, ULBP3, OR8D4, RIMS1, NPY2R are correlate with inflammation and immunity.
