Icariin Prevents H₂O₂-Induced Apoptosis via the PI3K/Akt Pathway in Rat Nucleus Pulposus Intervertebral Disc Cells

Figure 1

Icariin have no cytotoxicity in NP cells and had a significant protective effect on NP cells exposed to H₂O₂ at the concentration of 200 uM and this protective effect was attenuated by the PI3K/AKT pathway inhibitor LY294002. (a) H₂O₂ led to obvious cell death at the concentration of 200 uM to 600 uM. Results are presented as mean ± SD ( versus control group). (b) Icariin alone has no effect on the viability and proliferation of NP cells at concentrations up to 50 μM. (c) Icariin protects NP cells against H₂O₂-induced toxicity ( versus control group, versus H₂O₂ group).
