Preeclampsia (PE) belongs to hypertensive disorders of pregnancy (HDP), which can cause maternal death worldwide. This study aimed to identify the miRNA-mRNA-associated ceRNA network and to find new treatment schedules for PE.
4 microarray datasets were downloaded from the Gene Expression Omnibus database. We obtained 1737 differentially expressed mRNAs (865 upregulated and 872 downregulated) and 148 differentially expressed miRNAs (76 upregulated and 72 downregulated) from the placenta tissues of PE, respectively. Functional enrichment analyses of DEmRNAs were performed. The regulatory relationship between DEmiRNAs and DEmRNA was predicted via related databases. An miRNA-mRNA regulatory network was constructed.
hsa-let-7c and IGF1R were identified as potential regulators for PE, and function enrichment analysis showed that the PI3K-Akt signaling pathway was closely related. Therefore, ceRNAs might regulate the PI3K-Akt signaling pathway via the upregulation of IGF1R by binding to hsa-let-7c, affecting invasion of trophoblast, angiogenesis, and proinflammation in PE. Further study demonstrated that anticancer drugs including the PI3K inhibitor, AKT inhibitor, and IGF-1 inhibitor might be a potential solution for PE treatment.
The hsa-let-7c/IGF1R axis might affect the PI3K-Akt signaling pathway which is involved in the pathogenesis of PE, and inhibitors targeting this pathway might be used for PE treatment.
子痫前期(PE)属于妊娠期高血压疾病(HDP),可导致全球范围内的孕产妇死亡。本研究旨在识别miRNA-mRNA相关的ceRNA网络,并寻找PE的新治疗方案。
从基因表达综合数据库下载4个微阵列数据集。我们分别从PE胎盘组织中获得1737个差异表达的mRNA(865个上调和872个下调)和148个差异表达的miRNA(76个上调和72个下调)。对差异表达mRNA进行功能富集分析。通过相关数据库预测差异表达miRNA与差异表达mRNA之间的调控关系。构建miRNA-mRNA调控网络。
hsa-let-7c和IGF1R被确定为PE的潜在调节因子,功能富集分析表明PI3K-Akt信号通路与之密切相关。因此,ceRNAs可能通过与hsa-let-7c结合上调IGF1R来调节PI3K-Akt信号通路,影响PE中滋养层细胞的侵袭、血管生成和促炎反应。进一步研究表明,包括PI3K抑制剂、AKT抑制剂和IGF-1抑制剂在内的抗癌药物可能是PE治疗的潜在解决方案。
hsa-let-7c/IGF1R轴可能影响参与PE发病机制的PI3K-Akt信号通路,靶向该通路的抑制剂可能用于PE治疗。
