Inhibitory effect of bushen huoxue formula against dehydroepiandrosterone-induced inflammation in granulosa cells through TLR4/NF-kappa B signaling pathway
PAKISTAN JOURNAL OF PHARMACEUTICAL SCIENCES(2022)
摘要
Androgen exposure may be an important factor in promoting the development of polycystic ovary syndrome (PCOS) and disease progression. Bushen Huoxue Foimula (BHF), a traditional Chinese medicine, is prescribed in clinical settings as a PCOS remedy, albeit with unclear pharmacological effects on granulosa cells. The present research explores potentially advantageous BHF impacts and whereby BHF alleviates dehydroepiandrosterone (DHEA)-induced inflammation and endocrine disruption. Six chemical components in BHF were identified and fingerprint analysis showed good reproducibility. Using a human granulosa cell line (KGN), BHF effects on cell viability, secretion of steroidogenic and inflammatory factors were evaluated and TLR4/NF-kappa B pathway expression was examined. Our results demonstrate that BHF treatment of KGN cells in a DHEA-induced inflammatory state led to increased cell viability, decreased testosterone and estradiol production, and decreased CYP19A1 and HSD3B2 mRNA expression. Further experiments revealed that BHF inhibited the expression of pro-inflammatory cytokines and considerably hindered up-regulation in protein levels of TLR4, MyD88, and TRAF6, while inhibiting the activation of NF-kappa B and phosphorylation of I kappa B alpha. Collectively, BHF administration protected granulosa cells from DHEA-induced injuries through down-regulating pro-inflammatory cytokines and blocking the pathway of TLR4/NF-kappa B. Therefore, BHF hold promise as a therapeutic formulation for preventing androgen induced PCOS.
