Regulation of Bushen Zhuyun Prescription on Ovarian Endoplasmic Reticulum Stress in Rats with Luteal Phase Defect
To investigate the regulatory mechanism of Bushen Zhuyun prescription(BSZYP) on endoplasmic reticulum stress (ERS) in rats with luteal phase defect (LPD) induced by mifepristone.
Method
2
Fifty SD rats were randomly divided into a blank group, a model group, a positive control group (dydrogesterone,0.02 g·kg
-1
), and low-(0.08 g·kg
-1
)and high-dose (0.24 g·kg
-1
) BSZYP groups. Western blot and Real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR) were used to detect the mRNA and protein expression levels of immunoglobulin binding protein (BIP), protein kinase R-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1 (IRE-1), activating transcription factor 6 (ATF6), and C/EBP homologous protein (CHOP). The enzyme-linked immunosorbent assay (ELISA) was used to detect the serum progesterone (P) and estradiol (E
2
) levels.
Result
2
Compared with the blank group, the model group showed the elevated protein expression of BIP, PERK, and CHOP (
P
<
0.01) and the dwindled mRNA expression of PERK and CHOP (
P
<
0.05), while no significant difference was observed in the protein expression of IRE-1 and ATF6, mRNA expression of IRE-1, BIP, and ATF6, and serum E
2
and P levels. Compared with the model group, the positive control group displayed diminished protein expression of CHOP (
P
<
0.01), while no significant difference was observed in the protein expression of PERK, IRE-1, BIP, and ATF6, mRNA expression of PERK, IRE-1, BIP, ATF6, and CHOP, and serum levels of E
2
and P. The protein expression of CHOP decreased (
P
<
0.01) and the mRNA expression of CHOP increased (
P
<
0.05) in the low-dose BSZYP group, while no significant difference was observed in the mRNA and protein expression of PERK, IRE-1, BIP, and ATF6, and serum E
2
and P levels. In the high-dose BSZYP group, the protein expression of PERK, BIP, and CHOP was down-regulated (
P
<
0.01), and the mRNA expression of CHOP was up-regulated (
P
<
0.01), while no significant difference was observed in the protein expression of IRE-1 and ATF6, mRNA expression of PERK, IRE-1, BIP, and ATF6, and serum E
