Abstract:
Objective To explore the protective effects and mechanism of Shenqi Qiangjing granules containing serum on hydrogen peroxide(H2O2)induced oxidative damage and ferroptosis in mouse spermatogonia(GC-1 spg).Methods Thir-ty SPF grade healthy male SD rats were selected and randomly divided into blank group,levocarnitine group,and Shenqi Qiangjing granules group.After 7 days of intragastric administration,drug-containing serum was collected from each group.Using mouse sper-matogonia as a cell model,they were randomly divided into the normal control group,the model control group,blank serum group,levocarnitine containing serum group,and Shenqi Qiangjing granules containing serum group.Except for the normal control group,the other groups used hydrogen peroxide at a concentration of 600 μmol·L-1 to induce injury to mouse spermatogonia for 4 hours,and then established oxidative stress injury models,after 24 hours of medication intervention in each group.The survival rate of cells was detected using CCK-8 method;The levels of intracellular reactive oxygen species(ROS),malondialdehyde(MDA),catalase(CAT),glutathione(GSH),and superoxide dismutase(SOD)were detected by ELISA;The intracellular iron level was detected by iron ion colorimetry;The activities of Caspase-3 and Caspase-9 were detected by colorimetry;The mRNA levels of glu-tathione peroxidase 4(GPX4)and ACSL4 were determined by qRT-PCR.Results Compared with the normal control group,the cell proliferation activity of the model control group decreased significantly,the levels of ROS,MDA and Fe3+were significantly increased,while the activities of CAT,GSH and SOD were significantly decreased in the model control group,however,Caspase-3 and Caspase-9 activities were significantly increased,the results showed significant difference(P＜0.05).Compare with the model control group,Shenqi Qiangjing granules containing serum could significantly increase the cell proliferation activity,decrease the levels of ROS,MDA and Fe3+,increase the activities of CAT,GSH and SOD,and decrease the activities of Caspase-3 and Caspase-9,the results showed significant difference(P＜0.05).The qRT PCR results showed that compared with the model control group,the expression of GPX4 mRNA was upregulated and ACSL4 mRNA was downregulated in blank serum group containing Shenqi Qiangjing granules,and the differences were statistically significant(P＜0.05).Conclusions Shenqi Qiangjing granules have significant protective effects on hydrogen peroxide-induced oxidative stress injury and ferroptosis of spermatogonia in mice.The mechanism may be related to the decrease of Caspase-3 and Caspase-9 activities and the inhibition of oxidative stress injury and ferroptosis.
