Abstract:
This study aims to explore underlying mechanism of Lonicerae Japonicae Flos(LJF) in protecting rats against acute alcoholic liver injury(ALI) based on mitogen-activated protein kinase(MAPK) pathway. First, the targets of LJF in preventing ALI were predicted by network pharmacology and the component-target-pathway network was constructed, so that the key targets of LJF components acting on MAPK pathway were screened. Second, male SD rats were randomized into the control(KB) group, model(MX) group, positive(YX) group, and LJF high-(GJ), medium-(ZJ), and low-(DJ) dose groups. Each administration group was given(ig) corresponding drugs for 7 days and KB group and MX group received(ig) equal volume of distilled water every day. Except for KB group, rats were given Chinese spirit(56%, 3 days) for ALI modeling. The levels of aspartate transaminase(AST), alanine transaminase(ALT), interleukin-6(IL6) and tumor necrosis factor-α(TNF-α) in serum and malondialdehyde(MDA), glutathione(GSH), superoxide dismutase(SOD) and glutathione peroxidase(GSH-Px) in liver tissue of rats in each group were detected. Furthermore, we employed quantitative real-time PCR(qRT-PCR) to probe the effects of LJF on the key targets of MAPK pathway in ALI rats. A total of 28 active components of LJF were screened from TCMSP database, and 317 intersected with ALI-related targets. According to Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis, the 317 targets involved 226 pathways, which were mainly liver disease, inflammation, immunity, apoptosis and other related pathways. According to the MAPK pathway-target-active component network, the key active components of LJF, such as chlorogenic acid, hederagenol, and hyperoside, acted on 25 key targets of MAPK pathway. The results of in vivo experiments showed decreased levels of AST, ALT, and MDA in DJ, ZJ, and GJ groups(P<0.01 or P<0.05), reduced levels of IL6 in DJ and GJ groups(P<0.01 or P<0.05), and improved levels of SOD and GSH in ZJ and GJ groups(P<0.01 or P<0.05). The results of qRT-PCR demonstrated that the expression levels of mitogen-activated protein kinase kinase 4(MAPK2 K4) and mitogen-activated protein kinase 3(MAPK3) were decreased in DJ, ZJ, and GJ groups(P<0.01). The network pharmacology and experimental verification showed that the active components in LJF can reduce the inflammatory factor level and enhance the activities of SOD and GSH-Px by inhibiting the expression of key targets of MAPK pathway, thus alleviating and preventing liver damage caused by alcohol.
