Abstract
Background: The aim of this study was to establish a rat model of premature ovarian failure (POF) with cyclophosphamide (CTX), and explore the molecular basis of POF and the mechanism of Guishen-Erxian Decoction (GSEXD) to improve POF from the perspective of oxidative stress regulation of ovarian granulosa cell (OGC) DNA fragmentation.
Method: The study utilized SD rats to establish a POF model via CTX. Rats were divided into Control, POF group, three GSEXD dosage groups (low, medium, high), and a GSEXD+PI3K agonist group to assess GSEXD's therapeutic effects on oxidative stress, DNA fragmentation and ovarian damage.
Result: GSEXD can improve the body weight, ovarian index, pathological status, and hormone secretion of POF rats, and inhibit ovarian oxidative stress and DNA fragmentation. In addition, GSEXD inhibits the activation of the PI3K/Akt/FoxO3a pathway. PI3K agonist 740 Y-P can reverse the effects of GSEXD on ovarian function, ovarian antioxidant capacity, and granulosa cell DNA fragmentation in POF rats.
Conclusion: Inhibition of oxidative stress damage and excessive DNA fragmentation of granulosa cells is a key pathway for GSEXD to promote follicle growth and development and alleviate ovarian function decline, which may be related to the inhibition of the PI3K/AKT/FOXO3a pathway by GSEXD.
期刊介绍:
HISTOLOGY AND HISTOPATHOLOGY is a peer-reviewed international journal, the purpose of which is to publish original and review articles in all fields of the microscopical morphology, cell biology and tissue engineering; high quality is the overall consideration. Its format is the standard international size of 21 x 27.7 cm. One volume is published every year (more than 1,300 pages, approximately 90 original works and 40 reviews). Each volume consists of 12 numbers published monthly online. The printed version of the journal includes 4 books every year; each of them compiles 3 numbers previously published online.
