摘要 ETHNOPHARMACOLOGICAL RELEVANCE: Salvianolic acid B (SalB) is a polyphenolic compound in Salvia miltiorrhiza Bunge (Danshen), which has been largely used in Traditional Chinese Medicine for the treatment of metabolic syndrome, obesity, diabetes, among others.AIM OF STUDY: This study was to investigate the effects of Salvianolic acid B (SalB) on mRNA, lncRNA and circRNA''s expression profile in brown adipose tissue (BAT) of obese mice.MATERIALS AND METHODS: High-fat-diet induced obese C57BL/6J mice were treated with SalB (100mg/kg/day) for 8 weeks. Then, BAT was harvested for RNA-Seq analysis. Differentially expressed mRNAs, lncRNAs and circRNAs were analyzed using the Illumina Hiseq 4000. Following this procedure, bioinformatic tools including Gene ontology (GO), KEGG pathway and lncRNA-mRNA co-network analysis were utilized. Finally, RT-qPCR was performed to validate the differentially expressed RNAs.RESULTS: Compared with control group, 2532 mRNAs, 774 lncRNAs and 25 circRNAs were differentially expressed in SalB group. Additionally, 40 upregulated and 109 downregulated gene-related pathways were identified in the SalB group. Among them, metabolic pathways showed the highest enrichment coefficient in upregulated genes. Moreover, 54 up-regulated and 626 down-regulated coding mRNAs associated with lncRNA-Hsd11b1 and lncRNA-Vmp1.CONCLUSIONS: SalB may play an anti-obesity role by adjusting the expression of mRNAs correlated with inflammatory response and energy metabolism through regulating the expression of lncRNA-Hsd11b1. The findings of this research provide new directions to study the mechanisms of SalB, and would open therapeutic avenues for the treatment of obesity.
