ObjectiveTo investigate the changes and potential effects of differentially expressed microRNAs (miRNAs) in the development and progression of liver injury in a mouse model of autoimmune hepatitis (AIH) induced by concanavalin A (ConA). MethodsEight healthy male specific pathogen-free C57BL/6 mice were randomly divided into model group and control group, with four mice in each group. The mice in the model group were given tail vein injection of ConA 15 mg/kg, and those in the control group were given an equal volume of normal saline. All mice were sacrificed after 8 hours of modeling, Total RNA in liver tissue was extracted, gene microarray was used to screen out differentially expressed miRNAs, and target prediction and function analysis were performed for upregulated and downregulated miRNAs. The independent samples t-test was used for comparison of differentially expressed miRNAs between two groups. ResultsThe principal component analysis showed that the inter-group difference of the data extracted by gene microarray met the conditions for further analysis. Compared with the control group, the model group had 31 upregulated miRNAs and 18 downregulated miRNAs in mouse liver, which had a regulatory relationship with 959 target genes (601 upregulated genes and 358 downregulated genes). GO analysis showed that in the model group, the target genes of the upregulated miRNAs mainly had the molecular functions such as “DNA binding” (P=1.47×10-6), participated in the biological processes such as “transcription, DNA-templated” (P=2.36×10-7), and were mainly enriched in the cellular components such as “neuronal cell body” (P=5.99×10-6), while the target genes of the downregulated miRNAs had the molecular functions such as “RNA polymerase II proximal promoter sequence-specific DNA binding” (P=2.49×10-6), participated in the biological processes such as “regulation of transcription, DNA-templated” (P=1.64×10-11), and were mainly enriched in the cellular components such as “nucleoplasm” (P=4.30×10-10). KEGG pathway enrichment analysis showed that the target genes of the upregulated miRNAs were mainly enriched in “Endocytosis” (P=0.000 4), while the target genes of the downregulated miRNAs were mainly enriched in the “Hippo signaling pathway” (P=0.004), and the above functional analysis results were statistically significant (P＜0.05). ConclusionThere are differentially expressed miRNAs in the pathogenesis of AIH, and these differentially expressed miRNAs can provide new targets for the clinical treatment of AIH.
