淫羊藿苷對RAW264.7細胞破骨分化中MAPK信號通路的影響探究
[Abstract]:Objective to investigate the dose-effect and time-effect relationship of icariin (icariin,ICA) in inhibiting osteoclast differentiation, and to explore the effect of icariin on mitogen-activated protein kinase (mitogen-activated protein kinases,MAPKs) signaling pathway during monocyte differentiation into osteoclasts. In order to understand the molecular biological mechanism of icariin inhibiting osteoclast differentiation, it provides a theoretical basis for the further application of icariin in clinical practice. Methods the study was divided into two parts. Study on the dose-effect relationship of icariin in inhibiting osteoclast differentiation: RAW264.7 cells were divided into blank control group (equal medium control) and model control group (50ng/ml RANKL),) according to different concentrations of ICA. The number of osteoclasts was observed by 10-7/10-6/10-5/10-4mol/L ICA 50ng/ml RANKL). TRAP staining in four concentration gradient groups of ICA. At the same time, the expression and phosphorylation of key proteins were detected by western blot. The effect of icariin on osteoclast differentiation: the control group and icariin treated group (ICA concentration was 10-5mol/L) were used to observe the number of osteoclasts by TRAP staining. The expression and phosphorylation of key proteins were detected by western blot. Results Mononuclear cells containing more than 3 nuclei were found in a RAW264.7 induction culture for 48 hours. Trap staining showed that with the increase of ICA concentration, the number of osteoclasts decreased, the morphology of osteoclasts was small, and the number of nuclei was less. Compared with the control group, the phosphorylation level of p38 JNKK ERK in the model control group was higher than that in the control group, but there was no significant difference in the expression level of P38 + JNK-ERK between the model control group and the control group. Compared with the model control group without ICA, the phosphorylation level of P38 JNKERK decreased with the increase of ICA concentration, and the inhibitory effect was concentration-dependent, but there was no significant difference in the expression level of P38 JNKERK. When the concentration of ICA reached 10-5mol/L, the inhibitory effect on osteoclast differentiation of monocyte reached the best. TRAP positive osteoclasts were found in the solvent control group 12 hours after induction, and the number of osteoclasts increased with the increase of induction time. Compared with the solvent control group for the same induction time, the number of osteoclasts in ICA group was very small and the morphology of osteoclasts was smaller. The phosphorylation level of P38 JNK-ERK was different between the solvent control group and the ICA treatment group, but there was no significant difference in the expression level of P38 JNK-ERK between the same induction time group and the ICA treatment group. The phosphorylation level of P38 JNK-ERK in the solvent control group increased gradually with the increase of induction time, but there was no significant difference in the expression of P38 JNK-ERK. There was no significant difference in phosphorylation level and protein expression level of ERK. Conclusion Icariin has a stable inhibitory effect on osteoclast differentiation of monocytes, and the inhibitory effect is enhanced with the increase of icariin concentration. Icariin had no effect on the expression of p38 ERK and JNK in the MAPK signaling pathway during osteoclast differentiation, but could significantly inhibit its phosphorylation level, and the inhibitory effect was positively correlated with the concentration. The best concentration of Icariin in inhibiting osteoclast differentiation in vitro was 10-5 mol / L 路L ~ (-1) 路L ~ (-1). The inhibitory effect of icariin on osteoclast differentiation has reached a stable level since 12 hours.
