摘要:

背景:结核杆菌热休克蛋白10是引起骨结核骨质溶解和吸收主要因素之一,抑制成骨细胞的增殖。核因子κB受体活化因子配体及骨保护素是影响骨代谢的重要指标。
目的:观察重组结核杆菌热休克蛋白10对人成骨细胞增殖、碱性磷酸酶活性和核因子κB受体活化因子配体mRNA及骨保护素mRNA表达的影响。
方法:将人骨髓基质干细胞定向诱导分化筛选为成骨细胞,取第3代细胞,用含质量浓度为0.1,1,10 mg/L的重组结核杆菌热休克蛋白10培养液培养,对照组成骨细胞正常培养。
结果与结论:MTT实验结果显示,与对照组相比,不同质量浓度重组结核杆菌热休克蛋白10抑制成骨细胞增殖和碱性磷酸酶活性(P < 0.05)。RT-PCR实验显示,与对照组相比,不同质量浓度的重组结核杆菌热休克蛋白10均增加成骨细胞中核因子κB受体活化因子配体mRNA表达(P < 0.01),降低护骨素mRNA表达(P < 0.01),均呈剂量依赖性,质量浓度10 mg/L的重组结核杆菌热休克蛋白10作用最明显(P < 0.01)。结果证实,重组结核杆菌热休克蛋白10抑制成骨细胞增殖和碱性磷酸酶活性,通过调节核因子κB受体活化因子配体mRNA及骨保护素mRNA表达而影响骨代谢。

Abstract:

BACKGROUND: Mycobacterium tuberculosis heat shock protein 10 (r-Mt cpn10) is one of the main factors that cause bone tuberculosis dissolution and absorption as well as inhibits the proliferation of osteoblasts. Receptor activator of nuclear factor kappa B ligand and osteoprotegerin are the important factors influencing bone metabolism.

OBJECTIVE: To observe the effect of r-Mt cpn10 on human osteoblast proliferation, alkaline phosphatase secretion, expression of receptor activator of nuclear factor-kappa B ligand mRNA and osteoprotegerin mRNA.
METHODS: Human bone marrow stromal cells were induced to differentiate into osteoblasts, and osteoblasts at passage 3 were cultured with various concentrations of r-Mt cpn10 (0.1, 1, 10 mg/L). Osteoblasts cultured without r-Mt CPN10 were assigned as controls.
RESULTS AND CONCLUSION: MTT assay results showed that, compared with control group, r-Mt cpn10 at different concentrations inhibited osteoblast proliferation and alkaline phosphatase secretion (P < 0.05). RT-PCR analysis showed that, r-Mt cpn10 at different concentrations increased receptor activator of nuclear factor-kappa B ligand mRNA expression (P < 0.01), and inhibited osteoprotegerin mRNA expression in a concentration-dependent manner (P < 0.01). 10 mg/L r-Mt cpn10 exhibited the strongest effect (P < 0.01). The r-Mt cpn10 can inhibit osteoblast proliferation and alkaline phosphatase activity, and it may influence bone metabolism by regulating the expression of receptor activator of nuclear factor-kappa B ligand mRNA and osteoprotegerin mRNA.
