OBJECTIVE: To investigate the molecular mechanism of Huangjing Zanyu Capsule (HJZY), a new class-Ⅲ traditional Chinese medicine for the treatment of male infertility developed by Wang Qi, an academician of the Chinese Academy of Engineering, based on AMPK-mediated mitophagy in the treatment of oligoasthenospermia. METHODS: Acrolein (ACR) was used to treat GC-2spd(ts) mouse spermatocytes to establish a cell model of oligoasthenospermia. The optimal ACR concentration and exposure time for subsequent modeling were determined by CCK8 cell viability assay. After successful modeling, the cells were cultured in complete medium containing different concentrations of HJZY. Then, cell viability was assessed by CCK8 assay after 24 hours, and the subsequent treatment concentration was determined based on the cell viability. After the GC-2spd cells adhered to the wall, they were divided into a normal control (NC) group, a modeling group, and an ACR + HJZY treatment group. The effect of HJZY on mitophagy was observed by confocal fluorescence microscopy. The three groups of cells were transfected with siRNA-NC and siRNA- RESULTS: Through the cell viability assay, 34 μmol/L was selected as the the modeling concentration of ACR, and 20 minutes was selected as the modeling time The treatment concentration of HJZY was 160 μmol/L. Confocal fluorescence microscopy showed that HJZY had, to a certain degree, a positive regulatory effect on the mitochondrial membrane potential of damaged spermatogenic cells. The mitochondrial membrane potential of the model group decreased significantly compared with that of the NC group. After exposure to treatment, the cell membrane potential of the ACR + HJZY treatment group increased compared with that of the model group, and the difference was statistically significant ( CONCLUSION: HJZY may exert its therapeutic effect on oligoasthenospermia by regulating AMPK-mediated mitophagy.
