摘要:


文题释义:
红景天苷:红景天苷(C14H20O7,相对分子质量300.30)是从红景天属植物中提取的主要药理活性成分,目前广泛应用于医药领域。红景天苷具有多种药理特性,主要包括抗低氧、抗疲劳、抗癌、抗炎和抗衰老等作用。近年来研究发现红景天苷拥有促进成骨细胞增殖、分化的能力。
LY294002:是一种能够阻断三磷酸酰肌醇蛋白激酶(Phosphotidylinsitol-3-Kinase)细胞信号传导通路的蛋白激酶抑制剂,它是类黄酮化合物槲皮素的衍生物,可引发对磷酸肌醇3-激酶(PI3K)的更高抑制,被广泛用于三磷酸酰肌醇蛋白激酶细胞信号传导通路的特性研究中。

背景:骨缺损可直接影响牙齿种植的成功率及种植体的长期稳定性。研究显示红景天苷可促进成骨细胞增殖、分化,但对于其成骨分化相关通路具体研究不多。
目的:体外细胞实验研究红景天苷对MC3T3-E1细胞增殖和分化的影响,并探究其对相关基因和蛋白表达的影响。
方法:采用CCK-8实验和碱性磷酸酶实验筛选红景天苷(0.5,1,5,10,50 μmol/L)促进MC3T3-E1细胞增殖和分化的最佳浓度。实验分为4组:对照组、红景天苷组、红景天苷+LY294002组、LY294002组,分别用成骨诱导液、含10 μmol/L红景天苷、10 μmol/L红景天苷+10 μmol/L LY294002、10 μmol/L LY294002的成骨诱导液进行培养,观察红景天苷及PI3K/Akt信号通路抑制剂LY294002对成骨相关基因和蛋白表达的影响。
结果与结论:①CCK-8实验和碱性磷酸酶实验显示:红景天苷促进MC3T3-E1细胞增殖的作用在10 μmol/L时最显著;②与对照组相比,红景天苷可以促进矿化、促进细胞黏附、减少细胞死亡,提高Runx-2、骨钙素、骨桥蛋白的mRNA表达(P < 0.01),提高Runx-2和p-Akt蛋白表达(P < 0.01);而添加PI3K/Akt信号通路抑制剂LY294002则可逆转以上结果;③结果表明,红景天苷能促进 MC3T3-E1细胞矿化,并能促进成骨相关基因、蛋白的表达,这可能与PI3K/Akt信号通路的激活有关。

Abstract: BACKGROUND: Bone defects can directly affect the success rate and long-term stability of dental implants. Studies have shown that salidroside has the ability to promote the proliferation and differentiation of osteoblasts, but less is reported on its pathways related to osteogenic differentiation.
OBJECTIVE: To investigate the effects of salidroside on the proliferation and differentiation of MC3T3-E1 cells and the expression of related genes and proteins through in vitro cell experiments.
METHODS: Cell counting kit-8 test and alkaline phosphatase test were used to determine the optimal concentration of salidroside (0.5, 1, 5, 10, and 50 μmol/L) in promoting the proliferation and differentiation of MC3T3-E1 cells. There were four groups in the experiment: control group, salidroside group, salidroside+ LY294002 group, and LY294002 group, which were cultured with osteogenic induction solution, osteogenic induction solution containing 10 μmol/L salidroside, osteogenic induction solution containing 10 μmol/L salidroside+10 μmol/L LY294002, and osteogenic induction solution containing 10 μmol/L LY294002, respectively. The effects of salidroside and LY294002, an inhibitor of the PI3K/Akt signaling pathway, on the expressions of genes and proteins related to osteogenesis were observed.
RESULTS AND CONCLUSION: Cell counting kit-8 assay and alkaline phosphatase assay showed that salidroside promoted the proliferation of MC3T3-E1 cells most significantly at 10 μmol/L. Compared with the control group, salidroside could promote mineralization, promote cell adhesion, reduce cell death, increase mRNA expression of Runx-2, osteocalcin and osteopontin (P < 0.01), and increase protein expression of Runx-2 and p-Akt (P < 0.01). However, the addition of LY294002 reversed the above results. These findings indicate that salidroside can promote the mineralization of MC3T3-E1 cells and the expression of osteogenesis-related genes and proteins, which may be related to the activation of PI3K/Akt signaling pathway.
