Detoxification mechanism of psoralea corylifolia reverse compatibility based on the AMPK/GSK-3β/Nrf2 signaling pathway
To investigate the attenuating effect of reverse compatibility of psoralea corylifolia on rat liver and the underlying mechanism.
Methods
2
According to the random number table method
80 SD rats were divided into the blank group
the model group
the psoralea corylifolia group
the psoralea corylifolia + polygonum multiflorum 1∶1 group
the psoralea corylifolia + polygonum multiflorum 1∶2 group
the psoralea corylifolia + polygonum multiflorum 2∶1 group
the psoralea corylifolia + rehmannia glutinosa 1∶1 group
the psoralea corylifolia + schisandra chinensis 1∶1 group
with 10 rats in each group. Rats in all groups except for the blank group were subcutaneously injected with hydrocortisone (25 mg/kg) once a day for 14 days to establish a rat model of kidney yang deficiency. After the model of kidney yang deficiency was established
the rats were given corresponding drugs for 4 weeks; the drug dose was 12.6 g/kg in each group. HE staining was used to observe the pathological changes of rat liver tissue. The serum levels of alanine aminotransferase (ALT)
aspartate aminotransferase (AST)
alkaline phosphatase (ALP)
direct bilirubin (DBIL) and total bilirubin (TBIL) and the expression levels of superoxide dismutase (SOD)
malondialdehyde (MDA)
and glutathione peroxidase (GSH-Px) in liver tissue were detected by ELISA. The mRNA expression levels of NF-E2-related factor 2 (Nrf2)
Kelch-like epichlorohydrin-related protein 1 (Keap1)
heme oxygenase-1 (HO-1)
and quinone oxidoreductase NADH1 (NQO1) were detected by real-time PCR. The protein expression levels of phosphorylated AMPK (p-AMPK)
phosphorylated GSK-3β (p-GSK-3β)
Nrf2
and HO-1
which were involved in the AMPK/GSK-3β/Nrf2 signaling pathway
were determined by Western blotting.
Results
2
Compared with the psoralea corylifolia group
the structure of hepatic lobules in rats was improved and the inflammatory infiltration cells were reduced after the compatibility of psoralea corylifolia and medicinals for replenishing yin such as polygonum multiflorum
rehmannia glutinosa and schisandra chinensis. Compared with the psoralea corylifolia group
the serum levels of AST
ALT
ALP
DBIL
and TBIL of rats in the psoralea corylifolia+ polygonum multiflorum 1∶2 group
the psoralea corylifolia+ rehmannia glutinosa 1∶1 group
the psoralea corylifolia+ schisandra chinensis 1∶1 group were reduced (
P
<
0.01); the expression levels of SOD
GSH-Px and MDA in liver tissue of rats were improved in psoralea corylifolia+ polygonum multiflorum 1∶2 group (
P
<
0.01); the mRNA levels of Nrf2
HO-1
and NQO1 were up-regulated (
P
<
0.01) and the mRNA level of Keap1 was down-regulated (
P
<
0.01) in the psoralea corylifolia+ polygonum multiflorum 1∶2 group; the protein expression levels of p-AMPK
p-GSK-3β
Nrf2
and HO-1 were increased in the psoralea corylifolia+ polygonum multiflorum 1∶2 group
the psoralea corylifolia+ polygonum multiflorum 2∶1 group
the soralea corylifolia+ rehmannia glutinosa 1∶1 group
and the soralea corylifolia+ schisandra chinensis 1∶1 group (
P
<
0.05
P
<
0.01).
Conclusion
2
The compatibility of psoralea corylifolia and medicinals for replenishing yin polygonum multiflorum
rehmannia glutinosa and schisandra chinensis can improve the liver injury caused by psoralea corylifolia. The mechanism may be to activate the AMPK/GSK-3β/Nrf2 signaling pathway and inhibit the oxidative stress state to play a protective role in the liver. The compatibility ratio of psoralea corylifolia and polygonum multiflorum 1∶2 has the best attenuation effect.
