Da Chaihutang Protects Liver Mitochondrial Function of Nutritionally Obese Rats via CREB/PGC-1α Pathway
To observe the effects of Da Chaihutang on Cyclic adenosine monophosphate (cAMP)-response element binding protein (CREB)/peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1
α
) pathway in nutritionally obese rats and the protective mechanism on liver mitochondria.
Method
2
A total of 120 8-week-old male SD rats were randomly divided into a control group (
n
=20) and an experimental group (
n
=100). The rats in the control group were fed on a normal diet, while those in the experimental group were administered with a high-fat feed. Successfully modeled rats were randomly divided into a model group, a positive drug (metformin) group, and low-, medium- and high-dose Da Chaihutang groups (4.25, 8.5, and 17 g∙kg
-1
, respectively), with 20 rats in each group. After treatment with Da Chaihutang, the body weight, Lee's index, liver mitochondrial membrane potential and mitochondrial ultrastructure, PGC-1
α
expression and CREB phosphorylation of each group were measured and compared.
Result
2
Compared with the control group, the model group showed increased body weight and Lee's index (
0.01) to protect the integrity of mitochondrial structure, up-regulated PGC-1
α
expression and promoted CREB phosphorylation (
P
<
0.05,
P
<
0.01).
Conclusion
2
Da Chaihutang protects the structure and function of mitochondria and inhibits weight gain in obese rats by activating the CREB/PGC-1
α
pathway.
