Intervention effect of Liuwei Dihuang Decoction on ovariectomized rats and H2O2⁃induced oxidative damaged MC3T3⁃E1 cells based on antioxidant effect of FOXO1
Objective,2,To observe the intervention effect of Liuwei Dihuang Decoction on oxidative stress-related indices, bone turnover markers and the protein expression of FOXO1 in femoral in ovariectomized (OVX) rats. And to explore whether Liuwei Dihuang Decoction can exert antioxidant effect through FOXO1 and its mechanism.,Methods,2,(1) In animal experiment: Female Wistar rats were divided into normal group, sham-operated group, model group, Progynova group, N-acetylcysteine (NAC) group, Liuwei Dihuang Decoction high- and low-dose groups. Reactive oxygen species of bone marrow, serum antioxidant indices including SOD, CAT, GSH-PX, GSH and bone turnover markers including BALP, OCN, CTX-I, and the protein expression of FOXO1 in femoral were detected after 8 weeks of intervention. (2) In cell experiments, the decoction of Liuwei Dihuang was prepared and then the medicated serum of Liuwei Dihuang Decoction was collected, including medicated serum of control group, medicated serum groups with low-, medium-and high-dose. ①MC3T3-E1 cells were divided into normal group, model group, control medicated serum group, low-, medium- and high-dose medicated serum group of Liuwei Dihuang Decoction and NAC group. Protein expression of FOXO1 in each group was detected to verify the results of animal experiment. ②,FOXO1, gene expression of MC3T3-E1 cells was silenced. After verified by Western blot, the cells were divided into normal group, model group, NAC group, high-dose medicated serum group of Liuwei Dihuang Decoction, siNC group, siFOXO1 group, and siFOXO1+ high-dose group of Liuwei Dihuang Decoction medicated serum. The proliferation and ROS levels of cells in each group were detected. ③MC3T3-E1 cells were divided into normal group, model group, NAC group, control medicated serum group and high-dose medicated serum group of Liuwei Dihuang Decoction, and the protein expression of p-FOXO1 in each group was detected.,Results,2,(1) In animal experiment: Compared with the sham operation group, SOD, CAT, GSH-PX, GSH, BALP and OCN levels were significantly decreased (,P,<,0.05), while CTX-I, ROS levels and FOXO1 protein expression were significantly increased in the model group (,P,<,0.05). Compared with the model group, SOD, CAT, GSH-PX, GSH, BALP and OCN levels in high-dose group of Liuwei Dihuang Decoction were significantly increased (,P,<,0.05), while CTX-I, ROS levels and FOXO1 protein expression were significantly decreased (,P,<,0.05). (2) In cell experiment: ①Compared with the normal group, the protein expression of FOXO1 in MC3T3-E1 cells treated with H,2,O,2, was significantly increased (,P,<,0.05). The protein expression of FOXO1 in each dose group of medicated serum of Liuwei Dihuang Decoction was lower than that in the model group (,P,<,0.05). ②After silencing the ,FOXO1, gene in MC3T3-E1 cells, the cell proliferation in the siFOXO1 group at 48 h and 72 h was significantly lower than that in the model group and siNC group (,P,<,0.05), and the level of ROS was significantly higher than that in the model group and siNC group (,P,<,0.05). The cell proliferation in the siFOXO1+high-dose medicated serum of Liuwei Dihuang Decoction was significantly higher than that in the model group and siFOXO1 group at each time point (,P,<,0.05), but significantly lower than that in the high-dose group of medicated serum of Liuwei Dihuang Decoction (,P,<,0.05); the level of ROS was significantly lower than that in the model group and siFOXO1 group (,P,<,0.05), but significantly higher than that in the high-dose group of medicated serum of Liuwei Dihuang Decoction (,P,<,0.05). ③p-FOXO1/GAPDH in the model group was significantly lower than that in the normal group (,P,<,0.05), and p-FOXO1/GAPDH in the high-dose group of medicated serum of Liuwei Dihuang Decoction was significantly higher than that in the model group (,P,<,0.05).,Conclusion,2,Liuwei Dihuang Decoction can inhibit ROS levels in bone marrow of OVX rats, increase antioxidant levels in serum, promote bone formation and inhibit bone resorption in OVX rats. The mechanism may be partly related to promoting the phosphorylation of FOXO1 in osteoblasts.
