| 摘要 目的：探究氯化钴对于原代大鼠肺动脉成纤维细胞(PAF)的增殖、迁移、表型转化作用的影响。方法：分离培养大鼠肺动脉成纤维细胞，利用氯化钴刺激PAF细胞，并通过MTT、细胞划痕、Transwell、表型转化标志蛋白测定以及PI3K/Akt信号通路蛋白的变化研究氯化钴对PAF的影响。结果：MTT结果显示，与对照组相比，氯化钴可以抑制大鼠肺动脉成纤维细胞的增殖活性(P＜0.001)，并呈浓度依赖性。划痕实验及Transwell实验提示较高氯化钴(200 μmol?L-1)处理PAF细胞后可以抑制细胞迁移。随浓度增加，氯化钴可以抑制PAF的P110α、p-Akt蛋白表达。结论：氯化钴对于体外培养的原代大鼠肺动脉成纤维细胞的增殖、迁移和表型转化特性有一定的抑制作用，这可能与氯化钴抑制PI3K/Akt信号通路的表达有关。 |

| ABSTRACT Objective: Study the effects of cobalt chloride on the proliferation, migration and phenotype transformation on the pri- mary pulmonary artery fibroblasts (PAF) from rat. Methods: Using cobalt chloride to stimulate the established PAF. Value the effects of cobalt chloride on PAF by MTT, cell scratch, Transwell, phenotype marker protein expression and PI3K/Akt signaling pathway proteins expressions. Results: Compared with the control group, MTT results showed that cobalt chloride could decrease the proliferation activity of PAF in a concentration-dependent manner. Scratch and Transwell assays showed that higher concentrations of cobalt chloride could inhibit the migration of PAF. Cobalt chloride could decrease the protein expressions of P110α and p-Akt in a concentration-dependent manner. Conclusion: Cobalt chloride could inhibit the proliferation, migration and phenotype conversion characteristics of PAF by af- fecting the expression of PI3K/Akt signaling pathway which might involve in the regulation of cell behaviors. |
