Abstract:
ObjectiveTo optimize Tusizi prescription for ovarian reserve function based on the uniform design method combined with in vitro experiments and explore the underlying mechanisms of this prescription. MethodsThe uniform design method was adopted to design a 5-factor 11-level experiment on the water extract of Tusizi prescription. The cell-counting kit-8 (CCK-8) assay was employed to measure the viability of human ovarian granulosa cells (KGN cells) treated with Tusizi prescription extracts 1-11, and multivariate regression analysis was performed to determine the optimal herb ratio in this prescription. The potential targets of active ingredients in the prescription were retrieved from traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) and encyclopedia of traditional Chinese medicine (ETCM). The common targets shared by Tusizi prescription and diminished ovarian reserve (DOR) were selected and imported into search tool for the retrieval of interacting genes/proteins (STRING) to construct a protein-protein interaction (PPI) network and into gene function annotation database (DAVID) for gene ontology (GO) analysis. The CCK-8 assay was used to measure the viability of ovarian germline stem cells treated with hyperoside. The CCK-8 assay, 5-ethynyl-2'-deoxyuridine (EdU) staining, terminal-deoxynucleoitidyl transferase mediated nick-end labeling (TUNEL), and enzyme-linked immunosorbent assay (ELISA) were employed to examine the proliferation, apoptosis, and estradiol (E2) secretion of KGN cells treated with the water extract 11 of Tusizi prescription (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 4∶4∶2∶1∶1) and the optimal prescription screened by uniform design. On this basis, the optimal prescription composition for maximizing the effect on ovarian reserve function was determined and preliminary insights into the underlying mechanisms of this prescription were gained. ResultsA total of 147 common targets were obtained from 278 targets of Tusizi prescription and 1 721 targets of DOR. GO analysis revealed 194 biological processes, primarily involving cellular responses to exogenous compound stimuli, negative regulation of apoptotic process, and positive regulation of cell proliferation. It identified 84 cellular components, including cell membrane, mitochondria, and neuronal cell body, as well as 144 molecular functions such as enzyme binding, estrogen response element binding, and nuclear estrogen receptor binding. The multivariate regression analysis revealed that when Tusizi prescription was composed of Cuscutae Semen, Lycii Fructus, Dioscoreae Rhizoma, Poria, and Nelumbinis Semen in a ratio of 27∶30∶17∶12∶14, the water extract of Tusizi prescription had the best effect of enhancing the viability of KGN cells. CCK-8 results showed that compared with the normal group, the hyperoside group demonstrated increased viability of ovarian germline stem cells (P<0.01). The CCK-8, EdU, and ELISA results showed that compared with the normal group, the optimal prescription screened by uniform design and the water extract 11 of Tusizi prescription increased the proliferation and reduced the apoptosis of KGN cells (P<0.05, P<0.01). ELISA results showed that compared with the normal group, the water extract 11 of Tusizi prescription promoted the E2 secretion of KGN cells (P<0.05), while the optimal prescription screened by uniform design had no significant effect on the E2 secretion. ConclusionBoth the water extract 11 of Tusizi prescription (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 4∶4∶2∶1∶1) and the optimal prescription screened by uniform design (Cuscutae Semen-Lycii Fructus-Dioscoreae Rhizoma-Poria-Nelumbinis Semen 27∶30∶17∶12∶14) can improve the ovarian reserve function, and the former has better effect. Tusizi prescription can modulate biological processes (such as cell proliferation and apoptosis) and molecular functions (such as enzyme binding and estrogen response element binding) through active components like hyperoside to promote the proliferation and E2 secretion and inhibit the apoptosis of KGN cells, thereby protecting the ovarian reserve function.
