目的 探究叶酸对子宫内膜癌作用的靶基因。方法 通过转录组测序筛选叶酸作用下子宫内膜癌细胞中的差异基因,生存分析寻找对子宫内膜癌具有生存意义的差异基因,qPCR及western blot检测其在叶酸作用下的表达。结果 转录组测序发现36个差异基因,生存分析发现FMN1,TRIB3,INHBE及NRBP2的表达对子宫内膜癌具有生存意义,qPCR及western blot验证叶酸作用下NRBP2在子宫内膜癌细胞中的表达下调。结论 叶酸下调子宫内膜癌中NRBP2基因的表达,NRBP2可能是叶酸对子宫内膜癌作用的靶标。

Objective To explore the target genes of folic acid on endometrial carcinoma. Methods The differential genes in endometrial cancer cells treated with folic acid were screened by transcriptome sequencing. Survival analysis was used to find the differential genes with survival significance. QPCR and western blot were used to detect their expression under the action of folic acid. Results 36 differential genes were found by transcriptional sequencing. Survival analysis showed that the expression of FMN1,TRIB3,INHBE and NRBP2 had survival significance in endometrial carcinoma. QPCR and western blot confirmed that the expression of NRBP2 in endometrial cancer cells was down-regulated by folic acid. Conclusion Folic acid down-regulates the expression of NRBP2 gene in endometrial carcinoma, and NRBP2 may be the target of the effect of folic acid on endometrial carcinoma.
