title: [Bioinformatic analysis of target gene prediction and related signaling pathways of miRNA-126*].
abstract: OBJECTIVE
  To bioinformatically predict and analyze target genes of miRNA-126(*), with the aim of providing certain basis for related research about target genes and regulatory mechanism in the future.
  
  
  METHODS
  The miRNA chip technology was applied to measure expression levels of miRNA-126(*) in 3 time points (embryo 16, 19 and 21 days) of fetal lung development. Then the target genes of miRNA-126(*) were screened through miRGen2.0 database. Subsequent bioinformatic analysis of these target genes was performed by Gene Ontology analysis and Kyoto Encyclopedia of Genes and Genomes Pathway analysis (KEGG Pathway analysis).
  
  
  RESULTS
  miRNA-126(*) manifested continuously upregulated expression with the lung development (from embryo 16 to 21 days). There were 422 predicted target genes in total, and the gene set mainly located in glucuronosyltransferase activity, transferase activity (GO molecular function), multicellular organismal development, developmental process (GO biology process) and intracellular part (GO cellular component). The KEGG Pathway analysis demonstrated that the gene set mostly located in RNA degradation (signal transduction pathway) and prion diseases (disease pathway).
  
  
  CONCLUSIONS
  The results suggest that miRNA-126(*) plays a certain role in fetal lung development and provide a basis for lung development research in the future.
