High-throughput transcriptome-Seq and small RNA-Seq reveal novel functional genes and microRNAs for early embryonic arrest in humans.

High-throughput transcriptome-Seq and small RNA-Seq reveal novel functional genes and microRNAs for early embryonic arrest in humans. Gene. 2019 Feb 15;: Authors: Yang W, Lu Z, Zhi Z, Liu L, Deng L, Jiang X, Pang L Abstract Early Embryonic Arrest (EEA) is one of the major causes of female infertility. Genetic factors including specific genes and miRNAs may play pivotal roles on EEA. However, it is not well defined what genes and micro RNAs participate the pathophysiological alterations of EEA. In this work, we compared the Transcriptome -Seq and microRNA profiles from three pairs of villi (three EEA patients and three normal pregnancy, NP). We first confirmed the array data by qPCR with ten randomly selected differentially expressed genes and ten differentially expressed miRNAs in villi from 20 EEA and 20 NP controls. We next applied Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathway analysis and found that these differentially expressed genes enriched in the PI3K-Akt signaling pathway, Jak-STAT signaling pathway, MAPK signaling pathway, Complement and coagulation cascades, Hypertrophic cardiomyopathy (HCM), Dilated cardiomyopathy (DCM). Interestingly, hsa-miR-6515-5p and its target genes NLRP3, UGP2 may regulate the Immune system and carbohydrate metabolism. Hsa-miRNA 518 and its target gene EGR1 may regulate cell proliferation, angiogenesis, and cell apoptosis to impact early embryonic developmen...
