文题释义:
锌转运蛋白家族蛋白:
即锌铁调控蛋白,广泛存在于细菌、真菌、植物和动物。绝大多数锌转运蛋白含有8 个跨膜结构域,其氨基和羧基末端均位于细胞膜外或细胞器膜内,该区域被证实具有潜在的结合金属离子的能力,表明该区域很可能具有结合、调控和转运锌离子的功能。
基因转染技术的特点:是指通过物理或生物方法将目的基因导入到真核细胞的基因组中,使其调控靶细胞向特定的方向表达。常用的方法分非病毒方法和病毒载体方法,非病毒方法有微粒子轰击法、脂质体转染法、电穿孔法等,病毒方法有反转录病毒法、慢病毒法、腺病毒法及腺相关病毒法。

 

摘要
背景:
课题组前期研究已经证实乙醇能促进骨髓间充质干细胞成脂分化,上调肿瘤坏死因子α成脂通路蛋白PPARγ,aP2的表达。锌转运蛋白1(Zrt/Irt-like Protein 1,ZIP1)作为ZIP蛋白家族的成员与骨代谢和成骨分化有密切的关系。
目的:观察ZIP1 siRNA转染的骨髓间充质干细胞对肿瘤坏死因子α信号成脂通路的影响。
方法:分离培养兔骨髓间充质干细胞,使用0.03,0.09,0.15,0.21 mol/L乙醇进行培养,再使用ZIP1 siRNA转染骨髓间充质干细胞,同时对兔骨髓间充质干细胞进行ZIP1转染培养。
结果与结论:①aP2,PPARγ蛋白的表达:不同浓度乙醇培养aP2,PPARγ蛋白表达均较明显升高(P < 0.05);除0.03 mol/L乙醇组之外,其他浓度乙醇组三酰甘油水平明显升高(P < 0.05);沉默ZIP1基因转染乙醇培养的骨髓间充质干细胞后,各乙醇浓度组aP2,PPARγ蛋白的表达量及三酰甘油水平均明显升高( < 0.05),而骨髓间充质干细胞经ZIP1表达载体转染后,aP2,PPARγ蛋白表达明显降低( < 0.05);②结果表明:沉默ZIP1表达能激活骨髓间充质干细胞的肿瘤坏死因子α信号成脂通路的表达,从而发挥促进细胞的成脂分化能力。

Abstract:

BACKGROUND: Previous studies have confirmed that ethanol can promote adipogenic differentiation of bone marrow mesenchymal stem cells (BMSCs), and up-regulate the expression of PPARγ and aP2 in the tumor necrosis factor α (TNF-α) signaling pathway. As a member of the ZIP protein family, Zrt/Irt-like protein 1 (ZIP1) is closely related to bone metabolism and osteogenic differentiation.
OBJECTIVE: To study the effect of BMSCs transfected by ZIP1 on TNF-α signaling pathway in the process of adipogenic differentiation.
METHODS: The BMSCs from rabbits were isolated and cultured under different concentrations of alcohol (0.03, 0.09, 0.15, 0.21 mol/L), followed by transfection by ZIP1 siRNA and ZIP1 expression vector.
RESULTS AND CONCLUSION: After culture in alcohol, the expression levels of aP2 and PPARγ proteins were both significantly increased (P < 0.05), and the level of triglyceride was increased in all alcohol groups except for 0.03 mol/L alcohol group (P < 0.05). After siRNA transfection, the expression levels of aP2 and PPARγ as well as the level of triglyceride were increased significantly in all the alcohol groups (P < 0.05); however, ZIP1 transfection decreased the expression levels of aP2 and PPARγ proteins (P < 0.05). To conclude, ZIP1 siRNA could promote the adipogenic differentiation of BMSCs through the activation of TNF-α signaling pathway.
