Abstract
Triptolide (TP) is the major active ingredient of Tripterygium wilfordii Hook, a traditional Chinese herb that possesses various pharmacological activities and has been used to treat autoimmune and inflammatory diseases for thousands of years. However, the clinical application of TP is limited due to its multiorgan toxicity, and in particular, its negative impact on female fertility. To date, the specific toxic mechanisms on reproduction induced by TP remain unclear. In the current study, an LC-MS/MS-based metabolomic approach was adopted to study TP-induced reproductive toxicity and its mechanism. Histopathological examination of the ovaries showed that TP significantly induced follicular atresia and decreased the numbers of corpus luteum in rats, as well as reducing the gonadal index and destroying the microstructure of the ovary. Immunohistochemical staining revealed that TP significantly induced apoptosis of rat follicle cells. Metabolomics analysis revealed that 67 and 74 small molecule metabolites in the ovaries and serum, respectively (fold-changes > 1.5, p < 0.05), were significantly different in TP-treated rats compared to CON group rats. Target profiling identified the metabolites arachidonic acid, prostaglandin D2, prostaglandin H2 and prostaglandin E2 as potential serum biomarkers for TP-induced ovary damage.
