However, due to improper clinical use or misuse, resulting in liver damage. In this study, network pharmacology was employed to analyze the mechanism of cholestatic liver damage.

SPF (10 g/kg), psoralen, and isopsoralen (50 mg/kg each) were intragastrically administered to mice for 30 d.

A total of 126 pathways were enriched based on KEGG pathway analysis, with the “estrogen signaling pathway” identified as one of the top 20 pathways. In terms of pathological hepatic changes, treated mice had visually swollen hepatocytes, dilated bile ducts, and elevated serum biochemical markers, which were more prominent in mice treated with isopsoralen than in those treated with other compounds. Notably, the overexpression of SULT1E1 could reverse liver damage in each treatment group. B-ultrasound was used to observe the size of the gallbladder <em>in vivo</em>. The size of the gallbladder was found to significantly increase on day 30 after treatment in the SPF-, psoralen-, and isopsoralen-treated groups, especially the SPF group. Compared with the expression levels in the negative control group (rAAV8-empty + con), the expression levels of FXR, Mrp2, Bsep, SULT1E1, SULT2A1, Ntcp, and Nrf2 decreased, whereas those of CYP7a1 and IL-6 increased in the SPF-, psoralen-, and isopsoralen-treated groups.</div></div><div><h3>Conclusion</h3><div>The overexpression of SULT1E1 could alleviate the decreased or increased expression of indicators, indicating that SULT1E1 is an important target gene for SPF-induced liver damage.

Specifically, numerous studies have indicated that the levels of histone acetylation and methylation, DNA methylation, and noncoding RNA are altered in PTSD patients. Further to this, natural products have been found to achieve epigenetic regulation of PTSD by regulating the expression of epigenetic enzymes, long noncoding RNA (lncRNA), and miRNA, thereby playing a role in improving PTSD symptoms.
