Objective
2
To investigate the effect of Danggui Shaoyaosan (DSS) on the morphology and function of mitochondria in rats model of Alzheimer's disease (AD) and its possible mechanism.
Method
2
Rats model of AD was established by injection of streptozocin (STZ) into bilateral ventricles of SD rats. The 40 rats were randomly divided into sham group, model group, low, medium and high dosages of Danggui Shaoyaosan (12,24,36 g·kg
-1
·d
-1
) groups,observed the morphological changes of mitochondria in hippocampus of rats by electron microscopy after 14 days of continuous gavage.
In situ
end labeling(TUNEL) staining used to detect apoptosis and immunofluorescencereactive used to observe the expression of reactive oxygen species (ROS) and peroxisome proliferators-activated receptor
γ
coactivator lalpha (PGC-1
α
),quantitative Real-time polymerase chain reaction(Real-time PCR)detected the mRNA expression of dynamin-related protein 1 (Drp1),mitochondrial fusion protein 2 (MFN2) ,cytochrome C oxidase subunit Ⅳ (COX Ⅳ) and PGC-1
α
. Western blot detected the protein expression of adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK),phosphorylation(p)-AMPK,recombinant Sirtuin 1 (SIRT1) and PGC-1
α
.
Result
2
Compared with the sham group,the results of model group showed that the damage of mitochondria in hippocampus was more obvious,accelerated the ROS production and apoptosis rate (
P
<
0.01),decreased the mRNA level of MFN2,COX Ⅳ,PGC-1
α
,increased the mRNA level of Drp1,and descended the protein of p-AMPK/AMPK,SIRT1,PGC-1
α
(
P
<
0.05,
P
<
0.01).Compared with the model group,the medium and high dose of DSS group notably improved the damage of mitochondria,reduced the production of ROS and apoptosis rate (
P
<
0.01),promoted the mRNA expression of MFN2,COX Ⅳ,PGC-1
α
,inhibited the mRNA expression of Drp1,and up-regulated the protein of p-AMPK/AMPK,SIRT1,PGC-1
α
(
P
<
0.01).
Result
2
DSS can significantly ameliorate the mitochondrial homeostasis imbalance in AD rats.
