Objective

γ

α
(PGC-1

)/recombinant estrogen-related receptor

(ERR

) signaling pathway in rats with myocardial ischemia-reperfusion injury.
Method
2
Totally 90 male Wistar rats of SPF grade were randomly assigned into a sham operation group, a model group, and low-, medium-, and high-dose Wenxin prescription groups, with 18 rats in each group. The rats in low-, medium-, and high-dose Wenxin prescription groups were administrated with 0.99, 1.98, and 3.96 g·kg
-1
granules by gavage, respectively, and those in the sham operation group and model group with the same amount of normal saline. Twenty-one days after pre-administration, the rat model of myocardial ischemia-reperfusion injury was established by ligation of the left anterior descending coronary artery for 30 min and reperfusion for 2 h, and the rats in the sham operation group were only threaded without ligation. Myocardial infarction area was observed through 2,3,5-triphenyl-2h-tetrazolium chloride (TTC) staining, and the myocardial histopathology through hematoxylin-eosin (HE) staining. The levels of creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) in serum, cytochrome C oxidase (CCO) and succinate dehydrogenase (SDH) in mitochondrion, and ATP in myocardial tissue were detected according to kit instructions. The mRNA and protein levels of SIRT1, PGC-1
α
, ERR
α
, and mitochondrial transcription factor A (TFAM) in myocardial tissue were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively.
Result
2
Compared with the sham operation group, the model group showed broken and disordered myocardial fibers, cytoplasmic edema, and pyknosis and deviation of nuclei. Moreover, the modeling increased the levels of CK-MB and LDH (
P
<
0.05,
P
<
0.01), lowered the levels of ATP, CCO, and SDH (
P
<
0.05,
P
<
0.01), and down-regulated the mRNA and protein levels of SIRT1, PGC-1
α
, ERR
α
, and TFAM in myocardial tissue (
P
<
0.05,
P
<
0.01). Compared with the model group, Wenxin prescription reduced the myocardial infarction area (especially in the high-dose group,
P
<
0.01), restored the pathological changes, lowered the levels of CK-MB and LDH (
P
<
0.05,
P
<
0.01), increased the levels of ATP, CCO, and SDH (especially in the high-dose group,
P
<
0.01), and up-regulated the mRNA and protein levels of SIRT1, PGC-1
α
, ERR
α
, and TFAM in myocardial tissue (
P
<
0.05,
P
<
0.01).
Conclusion
2
Wenxin prescription can protect rats from myocardial ischemia-reperfusion injury by regulating myocardial mitochondrial energy metabolism via the SIRT1/PGC-1
α
/ERR
α
signaling pathway.
