1H-NMR-based metabolomics to dissect the traditional Chinese medicine promotes mesenchymal stem cell homing as intervention in liver fibrosis in mouse model of Wilson’s disease

Abstract

Abstract Background We administered Bushen Huoxue Huazhuo Formula (BSHXHZF) and transplanted bone marrow mesenchymal stem cells (BMSCs) into mice with Wilson’s disease (WD)-related liver fibrosis to evaluate the liver-protecting mechanism of this prescription. Methods Mice, randomly divided into different treatment groups, showed histopathological changes and degree of hepatocyte apoptosis. For hepatic hydroxyproline (Hyp) determination, transforming growth factor-β1 (TGF-β1) and bone morphogenetic protein-7 (BMP-7) mRNA and protein were measured. Chemical profiling of the extract of BSHXHZF using The liquid chromatography-mass spectrometry (LC-MS/MS) and revealing its antifibrosis mechanism using metabolomics. Results TCM+BMSC group livers exhibited few inflammatory cells. TUNEL revealed abundant brown apoptotic cells in model control groups, while the TCM+BMSC groups showed a significant increase in blue negative expression of liver cells. Hyp in toxic milk (TX) mice groups was significantly lower than that in model control groups (MG). Compared with MG, TGF-β1 expression was significantly lower than all other groups, while BMP-7 expression was significantly higher. Metabolic analysis identified 20 potential biomarkers and 10 key pathways, indicating that BSHXHZF+BMSC intervention has a significant regulatory effect on metabolic disorders of these small molecule substances. Conclusion BSHXHZF combined with BMSCs can inhibit liver fibrosis and hepatocyte apoptosis by improving related metabolic disorders, and achieving therapeutic effects in WD-related liver fibrosis.
