Abstract
Previous research has indicated that Polyphyllin I (PPI) possesses potent anticancer properties. However, its impact on endometriosis remains unexplored. This study aims to investigate the inhibitory effects of PPI on ectopic endometrial stromal cells (EESCs). The CCK-8 and flow cytometry results respectively showed that the cell viability of EESCs decreased and the number of apoptotic cells increased in a dosage dependent of PPI. Wound healing and transwell assays demonstrated a notable reduction in cell motility and migration ability in the PPI group. Moreover, the Western blot analysis revealed a decrease in p62 levels and an increase in LC3-II expression following PPI administration. Additionally, the protein levels of p-Akt and p-mTOR were observed to decrease with increasing concentrations of PPI, indicating the potential of PPI to induce autophagy in EESCs through modulation of the Akt/mTOR signalling pathway. Consequently, PPI holds promise as a targeted therapeutic agent for the management of endometriosis.
