摘 要:目的观察六味地黄丸含药血清对氧化应激状态下MC3T3-E1细胞增殖、活性氧及自噬水平的影响。方法用过氧化氢(H 2O 2)模拟氧化应激状态后采用不同浓度的六味地黄丸含药血清干预MC3T3-E1细胞,CCK-8法检测细胞增殖情况;通过细胞活性氧(reactive oxygen species,ROS)检测细胞ROS水平;qRT-PCR检测自噬相关基因Beclin 1、LC3B mRNA表达情况;蛋白印迹法检测自噬相关蛋白Beclin 1、LC3B表达情况。结果①CCK-8结果显示,H 2O 2会抑制成骨细胞的增殖,当其浓度为0.10 mmol/L时具有相对较小程度的抑制增殖效果;六味地黄丸含药血清可以促进氧化应激状态下成骨细胞的增殖,且当体积浓度为20%时促进增殖的效果最好。②细胞活性氧检测结果显示,六味地黄丸含药血清组ROS水平降低(P<0.05)。③qRT-PCR结果显示,六味地黄丸组Beclin 1、LC3B mRNA表达上调(P<0.05),且该作用会被自噬抑制剂所抑制。④蛋白印迹法结果显示,六味地黄丸组Beclin 1蛋白表达上调(P<0.05),蛋白LC3Ⅱ/Ⅰ比值增高(P<0.05)。结论六味地黄丸含药血清可以促进氧化应激状态下成骨细胞增殖、降低细胞ROS水平,其机制可能与诱导细胞自噬相关。Objective To observe the effects of Liuwei Dihuang pill-containing serum on the proliferation and reactive oxygen species and autophagy levels of MC3T3-E1 cells under oxidative stress.Methods MC3T3-E1 cells were intervened with different concentrations of Liuwei Dihuang pill-containing serum after simulating oxidative stress with hydrogen peroxide(H 2O 2).Cell proliferation was detected with CCK-8 method.Cell ROS levels were detected with cell reactive oxygen species(ROS).mRNA expressions of autophagy-related genes Beclin 1 and LC3B were detected with qRT-PCR.The expressions of autophagy-related proteins Beclin 1 and LC3B were detected with Western blotting.Results(1)CCK-8 result showed that H 2O 2 inhibited the proliferation of osteoblasts,and it had a relatively small inhibitory effect when its concentration was 0.10 mmol/L.Liuwei Dihuang pill-containing serum promoted the proliferation of osteoblasts under oxidative stress,and the best effect was achieved when the volume concentration was 20%.(2)The result of cell ROS detection showed that the ROS level in Liuwei Dihuang pill-containing serum group decreased(P<0.05).(3)The result of qRT-PCR showed that Beclin 1 and LC3B mRNA expressions were up-regulated in the Liuwei Dihuang pill group(P<0.05),and the effect was inhibited by autophagy inhibitors.(4)Western blotting result showed that expression of Beclin 1 was up-regulated and LC3II/Ⅰratio was increased(P<0.05).Conclusion Liuwei Dihuang pill-containing serum promotes osteoblast proliferation and reduces cellular ROS levels under oxidative stress.The mechanism may be related to the induction of cellular autophagy.
