Bioinformatic analysis of peripheral blood circRNA in depression disorder / 中华行为医学与脑科学杂志

ABSTRACT

ObjectiveTo predict the target genes of miRNA associated with hsa_circRNA_102802 and hsa_circRNA_104597 using bioinformatics methods,and analyse the biological process and signaling pathway.MethodsTargetscan,miranda and mirbase three online database were used to predict target genes of miRNAs which are complementary to circRNAs.Target genes of miRNAs prediction results were taken their intersection of three online database,then take their collection as total target genes of miRNAs.The results were analyzed by gene ontology(GO) and KEGG pathway analysis using FunNet.Results199 target genes of has_miR_204_5p,has_miR_809,has_miR_520_5p,has_miR_423_5p,has_miR_617 and has_miR_877_5p were gotten from the intersection of 3 databases;and 410 targets of has_miR_659_3p,has_miR_9_5p,has_miR_661,has_miR_576_3p,has_miR_548d_5p,has_miR_548a_5p,has_miR_548b_5p,has_miR_876_5p and has_miR_744_5p were gotten from the intersection of 3 databases.GO analysis showed that Target genes involved in diverse biological processes including central nervous system,such as cortex development,axon guidance and extension,synaptic transmission,as well as the process of learning and memory (P<0.05).Enriched pathways were also revealed target genes involved in the signal path including the axon guidance,glutamic acid synapses,Wnt signaling pathway,ErbB signaling pathway,mTOR signaling pathway and VEGF signaling pathway,which connect closeiy with depression.hsa_circRNA_102802 and hsa_circRNA_104597 may play an important role in depression.Conclusionshsa_circRNA_102802 and hsa_circRNA_104597 may be associated with the pathologenesis of depression disorder.
