Introduction Formononetin (MBHS) and its glycosylated derivative ononin (MBHG), as the major isoflavones, have exhibited the anti- inflammatory impacts on the lipopolysaccharide (LPS)-induced inflammation. Although various researches have focused on interpreting the pharmaceutical activities of MBHG and MBHS, the molecular mechanisms in zebrafish models are still unclear. Objective The purpose of the present work is to investigate the molecular mechanisms of the anti-inflammatory effects of MGHG and MBHS based on lipidomics and targeted transcriptomics. Methods UHPLC-MS was applied for the lipid analyses and RT-PCR was adopted for the mRNA analyses, and the results of different groups were compared for exploring the significantly changed lipids and mRNAs. Results The results of lipidomics revealed that phosphatidylcholines (PCs) were drastically down-regulated in the MBHG or MBHS treated LPS-induced inflammatory zebrafish models. Besides, MBHS can also decrease the levels of triacylglycerols (TAGs). For the targeted transcriptomics analyses, 4 cytokines (TNF-alpha, IL-1 beta, IL-6 and IFN-gamma) and 3 mRNA (JNK1, ERK1 and p38a) involved in the MAPK pathway were down-regulated and IL-10 was up-regulated under the treatment of MBHG or MBHS. Conclusion Combining the results of lipidomics and targeted transcriptomics, we indicated that MBHG and MBHS exerted potent anti-inflammatory effects on the LPS-induced zebrafish models through the MyD88 or TRIF MAPK/ ERK and MAPK/JNK pathways and the glycerophospholipid, glycosylphosphatidylinositol (GPI)-anchor biosynthesis and glycerolipid metabolisms. Our results provided new insights into the anti-inflammatory mechanisms of MBHG or MBHS and supplied an effective method to interpret the pharmacological mechanisms of drugs.
