Abstract
OBJECTIVE To observe the effect of herb-partitioned moxibustion (HPM) on the miRNA expression profile of thyroid tissue in experimental autoimmune thyroiditis (EAT) rats. METHODS Rats were randomly divided into normal control (NC) group, EAT model (EAT) group, HPM group and western medicine (Med) group. EAT model rats were prepared by a combined immunization with complete and incomplete Freund's adjuvant emulsified with porcine thyroglobulin and iodine. Rats in the HPM group were treated with HPM, while rats in the Med group were treated with levothyrocine (1 μg/2 mL) by gavage. HE staining was used to observe the pathological morphological changes of thyroid tissue, ELISAs was uaed to detect the serum concentrations of TGAb, TPOAb, FT3, FT4, TSH. We then performed high-throughput miRNA sequencing to analyse the miRNA expression profiles in the thyroid tissues, followed by a bioinformatics analysis. RT-qPCR was used to verify the identified differentially expressed miRNAs. RESULTS HPM improved the thyroid tissue morphology and reduced serum TPOAb, TGAb, TSH concentration in EAT rats (P < 0.05), but with no obvious effect on FT3 and FT4 concentration. While the TSH, FT3 and FT4 concentration was significantly changed in the Med group (P < 0.01 or P < 0.05) compared with that of EAT group. Sequencing results showed that a total of 17 miRNAs were upregulated, and 4 were downregulated in the EAT rats, in which the expression levels of miR-346 and miR-331-5p were reversed by HPM. The target genes of the miRNAs that regulated by HPM were associated with a variety of immune factors and immune signals. RT-qPCR verification showed that the expression of miRNA-346 and miRNA-331-5p was consistent with the sequencing results. CONCLUSIONS HPM could regulate the the expression of miRNA-346 and miRNA-331-5p, then act on their target genes to immune and inflammation-related pathways, which may be one of the mechanisms of HPM on EAT rats.
