Sumario:BACKGROUND: Traditional Chinese medicine (TCM) with single or compound materials is an effective cure for liver fibrosis. Hepatic stellate cells (HSCs) play a key role in liver fibrosis pathology and have become a novel drug target for this condition. METHODS: CCK-8 assay was used to determine the cytotoxicity of four components, SYPA, HSYPA, Apigenin, and Luteolin, from Deduhonghua-7 powder on HSC-T6 cells. Transforming Growth Factor β 1 (TGFβ1)-induced fibrotic cell model and CCI(4)-induced fibrotic rat model were constructed, the expression of fibrosis-related genes, the pathological changes and serum biochemical markers were evaluated. Proteomic analysis was performed to determine the mechanism by which luteolin attenuated liver fibrosis, which were further confirmed by Western blot. RESULTS: Luteolin attenuates liver fibrosis in HSC-T6 cells and luteolin decreases the liver fibrosis index level in vivo. A total of 5000 differentially expressed proteins (DEPs) were obtained using proteomic analysis. KEGG analysis found that DEPs were concentrated in various metabolic pathways, including DNA replication and repair and lysosomal signaling. GO analysis showed that molecular functions included the activity and binding of various enzymes, related cellular components included the extracellular space, lysosomal lumen, mitochondrial matrix, and nucleus, and biological processes included collagen organization and biosynthesis and the positive regulation of cell migration. Western blot results showed that CCR1, CD59, and NAGA were downregulated in TGFβ1 treatment, while upregulated both in Lut2 and Lut10 treatment. Meanwhile, eight proteins, ITIH3, MKI67, KIF23, DNMT1, P4HA3, CCDC80, APOB, FBLN2, that were upregulated in TGFβ1 treatment, while downregulated both in Lut2 and Lut10 treatment. CONCLUSION: Luteolin was shown to have a strong protective effect on liver fibrosis. CCR1, CD59, and NAGA may promote liver fibrosis while ITIH3, MKI67, KIF23, DNMT1, P4HA3, CCDC80, APOB, and FBLN2 may facilitate protection against fibrosis.
