| 摘要: |
| 目的 探讨人脐带间充质干细胞外泌体(human umbilical cord mesenchymal stem cell exosomes，hUCMSC-Exo)缓解肺动脉高压(pulmonary hypertension，PH)的潜在分子作用机制。方法 对hUCMSC-Exo进行提取、鉴定及高通量测序。利用GeneCards搜索PH作用靶点，在GEO数据库下载PH相关芯片(GSE53408、GSE113439)，经过批次校正后筛选出差异基因。GeneCards和GEO数据库以及hUCMSC-Exo所含miRNAs预测的靶向调控的mRNAs取交集，构建蛋白互作网络筛选出hUCMSC-Exo作用于PH的关键靶点，并进行GO和KEGG富集分析。结果 测序得到hUCMSC-Exo中43个高表达的miRNAs，其中17个miRNAs可作用于PH，发现其作用机制可能与前列腺癌、HIF-1信号通路、PI3K-Akt信号通路、癌症的蛋白多糖和癌症通路等相关。结论 本研究可为hUCMSC-Exo防治PH的临床研究提供新思路。 |

| Abstract: |
| OBJECTIVE To explore the potential molecular mechanism of human umbilical cord mesenchymal stem cell exosomes(hUCMSC-Exo) in alleviating pulmonary hypertension(PH). METHODS The hUCMSC-Exo were high-throughput sequenced after extracted and identified. PH target was searched in GeneCards. PH-related chip GSE53408 and GSE113439 were downloaded from GEO databases and screened for the differential genes after batch correction. The target genes in GeneCards and GEO databases and the target regulated genes predicted by miRNAs contained in hUCMSC-Exo were used for intersection. The protein-protein interaction network was constructed to screen out the key targets of hUCMSC-Exo acting on PH, then went for GO and KEGG analysis. RESULTS Forty-three high expression miRNAs were collected after hUCMSC-Exo sequenced. A total of 17 miRNAs might affect PH through prostate cancer, HIF-1 signaling pathway, PI3K-Akt signaling pathway, proteoglycans in cancer and pathways in cancer. CONCLUSION This study provides a new idea for exploring the role of hUCMSC-Exo in alleviating PH. |
