目的
2
探讨黄诺玛苷对胰岛素抵抗小鼠小肠类器官转录组的影响。
方法
2
首先建立C57BL/6J和db/db小鼠小肠类器官;采用免疫荧光法检测细胞核核抗原(ki-67)和上皮细胞E-钙黏蛋白(E-cadherin)表达;将小肠类器官分为3组,分别是以C57BL/6J小鼠小肠类器官为正常组、db/db小鼠小肠类器官为模型组和db/db小鼠小肠类器官黄诺玛苷干预组为给药组(FM组);采用蛋白免疫印迹法(Western blot)检测3组小肠类器官胰高血糖素样肽-1(GLP-1)蛋白的表达;并对3组样本进行转录组测序。
结果
2
小肠类器官培养第6天形成围绕管腔周围的环状结构,初步建立了小肠类器官培养模式;免疫荧光检测结果显示小肠类器官均表达ki-67和E-cadherin;Western blot结果显示黄诺玛苷可增加GLP-1蛋白的表达;差异基因表达分析中,模型组与正常组相比差异表达基因共有1 862个,FM组与模型组相比差异表达基因共有2 282个;通过蛋白质-蛋白质相互作用(PPI)网络分析2组共同表达的差异基因,得到

Objective
2
To investigate the effects of flavanomarein on the transcriptome of small intestinal organoids in insulin-resistant mice.
Method
2
Firstly, small intestinal organoids of C57BL/6J and db/db mice were established. Ki-67 and E-cadherin expression was determined by immunofluorescence. Small intestinal organoids were divided into the following three groups: C57BL/6J mouse small intestinal organoids as the normal control group, db/db mouse small intestinal organoids as the model group (IR group), and db/db mouse small intestinal organoids treated with flavanomarein as the administration group (FM group). Western blot was used to detect the expression of glucagon-like peptide-1(GLP-1) protein on the small intestinal organoids of the three groups. Finally, transcriptome sequencing was performed on samples from the three groups.
Result
2
On the 6
th
day of small intestine organoids culture, a cyclic structure was formed around the lumen, and a small intestine organoids culture model was preliminarily established. Immunofluorescence detection showed that ki-67 and E-cadherin were expressed in small intestinal organoids. Western blot results showed that the expression of GLP-1 protein was increased by flavanomarein. In the results of differential expressed gene (DEG) screening, there were 1 862 DEGs in the IR group as compared with the normal control group, and 2 282 DEGs in the FM group as compared with the IR group. Through protein-protein interaction(PPI) network analysis of the DEGs of the two groups, 10 Hub genes, including

, and

, were obtained. These genes were highly expressed in the normal control group, and their expression was reduced in the IR group. After the intervention of flavanomarein, the expression of the above genes was reversed.
Conclusion
2
Flavanomarein may play its role in improving insulin resistance by reversing the expression levels of 10 Hub genes, including
