title: MicroRNA expression profile in different tissues of BALB/c mice in the early phase of Schistosoma japonicum infection.
abstract: Schistosomiasis remains an important global public health problem that affects 200 million people in 76 countries. The molecular mechanisms of host-parasite interaction are complex, and in schistosome infection regulation of microRNA (miRNA) and the host micro-environment may be involved. In this study, an miRNA microarray was applied to investigate differences in miRNA expression in different tissues of mice before and 10 days post infection. In total, 220 miRNAs were detected in different tissues of the BALB/c mice before and after infection, including 8 miRNAs in liver, 8 in spleen and 28 in the lungs with up-regulated expression, and 3 miRNAs in liver, 5 in spleen and 28 in the lungs with down-regulated expression in mice 10 days post infection with schistosomes. The functions of these differentially expressed miRNAs are related mainly to the immune response, nutrient metabolism, cell differentiation, apoptosis, and signal pathways. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of the differentially expressed miRNAs revealed that many important biological pathways are triggered by schistosome infection in BALB/c mice, such as the MAPK signaling pathway, insulin signaling pathway, Toll-like receptor signaling pathway and TGF-β signaling pathway.The results reveal that miRNAs may be an important regulator of schistosome-host interaction in the early phase of Schistosoma japonicum infection. The data presented here provide valuable information to increase understanding of the regulatory function of the miRNAs in the host micro-environment, as well as the mechanism of host-parasite interactions. This may be helpful in the search for potential new drugs, and for biomarkers of early S. japonicum infection applicable in the future control of schistosomiasis.
