Sini San ameliorates lipid metabolism in hyperprolactinemia rat with liver-depression

Abstract

Sini San (SNS) is used to treat liver depression and is applied in both food and herbal medicine. Hyperprolactinemia (HPRL) is a common endocrine disorder, and patients with HPRL are usually associated with depressive symptoms. However, whether SNS is effective in treating HPRL combined with liver depression and its underlying mechanisms are unknown. We applied network pharmacology and molecular docking to predict the mechanism of SNS for the treatment of liver-depressed HPRL. Therapeutic effects were validated in animal models and cells. Metabolomics was also used to evaluate the effect of SNS on liver-depressed HPRL. Network pharmacology and molecular docking analysis showed that AKT1, TNF and IL6 were the key targets, and SNS improved depressive behaviors, regulated sex hormone levels, and improved ovarian morphology. Combined network pharmacology and metabolomics analyses showed that SNS could act by regulating lipid metabolism. In addition, SNS significantly reduced the release of prolactin (PRL) in rat pituitary tumor MMQ cells. Overall, SNS can significantly treat HPRL liver depression at both animal and cellular levels, and effectively alleviate the related symptoms by regulating lipid metabolism. AKT1, TNF and IL6 may be key targets.
