Mechanism of Jiawei Bazhen Yimu Capsule in Treatment of Premature Ovarian Failure Based on Estrogen Signaling Pathway增强出版
To investigate the effect of Jiawei Bazhen Yimu capsule on serum sex hormones, sexual organs and estrogen signaling pathway in female rats with premature ovarian failure.
Method
2
The key target proteins of Jiawei Bazhen Yimu capsule in the treatment of premature ovarian failure were screened out by network pharmacology analysis. Female healthy SD rats were selected
and the rat model of premature ovarian failure was established by ovariectomy. Fifty ovariectomized rats were randomly divided into a model group
an estradiol (E
2
) valerate group
and Jiawei Bazhen Yimu capsule low
medium
and high-dose groups. Another 10 healthy female rats were set as a sham operation group. The sham operation group and the model group were given distilled water by gavage
and other administration groups were given corresponding doses of drugs by gavage. After 21 d
the serum hormone levels of female rats were measured
including E
2
progesterone (P)
follicle stimulating hormone (FSH)
and luteinizing hormone (LH). Immunofluorescence staining (IF) was used to detect the protein expression levels of estrogen receptor 1 (ESR1)
estrogen metabolism P4503A4 enzyme (CYP3A4)
and P45019A1 enzyme (CYP19A1) in the uterine tissues of female rats.
Result
2
As compared with the model group
the serum E
2
and P levels of female rats in the Jiawei Bazhen Yimu capsule low
medium
and high-dose groups were significantly increased. Jiawei Bazhen Yimu capsule improved the endometrial status of female rats and increased positive expression of ESR1
CYP3A4
and CYP19A1 in the uterine tissues of female rats (
P
<
0.05).
Conclusion
2
The mechanism of Jiawei Bazhenyimu capsule in the treatment of premature ovarian failure may be related to its hormone-like effect and activation of the estrogen signaling pathway.
