Effect of Zishen Huoxue Prescription on Regulation of Mitophagy and Neurogenesis in Hippocampal CA1 Region of Vascular Dementia Rats
To investigate the effect of Zishen Huoxue prescription on promoting neurogenesis in hippocampal CA1 region of vascular dementia (VD) rats by regulating mitophagy.
Method
2
The 2-VO method was used to establish the VD rat model and 60 SD rats were randomly divided into sham operation group, model group, donepezil hydrochloride group, and Zishen Huoxue prescription low-dose(8.9 g·kg
-1
), medium-dose(17.8 g·kg
-1
) and high-dose(35.6 g·kg
-1
) groups. Morris water maze test was performed to detect the escape latency and the number of crossing platform in each group. The expression of phosphatase and tensin homology-induced kinase 1 (PINK1) and Parkinson protein (Parkin) mRNA in hippocampal CA1 region was detected by Real-time fluorescent quantitative polymerase chain reaction(Real-time PCR). Western blot was used to determine the expression of mitochondrial autophagy signaling pathway-related proteins Parkin, prohibitin 2 (PHB2), mitofusin 2 (Mfn2) and dynamin-related protein 1 (Drp1) in hippocampal CA1 region. The neurogenesis in hippocampal CA1 region was tested by Brdu method.
Result
2
Compared with the conditions in the sham operation group, the learning and spatial memory abilities of the model group were decreased (
P
<
0.05), with damaged mitochondrial structure and autolysosome formation in the hippocampal CA1 region. The expressions of Parkin, Pink1 mRNA and Parkin, PHB2, and Drp1 proteins were up-regulated (
P
<
0.05), while the expression of Mfn2 protein and the neuronal regeneration in hippocampal CA1 region were reduced (
P
<
0.05,
P
<
0.05). Compared with the conditions in the model group, Zishen Huoxue prescription enhanced the learning and spatial memory abilities of VD rats (
P
<
0.05), increased the number of autophagosomes in hippocampal CA1 region and improved the mitochondrial structure. The expression of Parkin, Pink1 mRNA and Parkin, PHB2, and Drp1 proteins in hippocampal CA1 region was up-regulated (
P
<
0.05,
P
<
0.01)while the expression of Mfn2 protein was down-regulated(
P
<
0.05,
P
<
0.01). The number of new neurons in hippocampal CA1 region was also increased(
P
<
0.05,
P
<
0.01).
Conclusion
2
The promoting effect of Zishen Huoxue prescription on the neurogenesis in hippocampal CA1 region of VD rats was related to the mitophagy mediated by Pink1/Parkin signaling pathway.
