摘要: 目的 研究地塞米松对人甲状腺滤泡上皮细胞凋亡的影响及其临床意义。方法 分离原代甲状腺滤泡上皮细胞,以0、10-6、10-4和10-4mol/L地塞米松刺激单层培养的甲状腺细胞,用MTT、流式细胞术及荧光定量PCR法检测刺激前后甲状腺细胞的增殖抑制率、凋亡率及凋亡相关基因mRNA的表达。结果 地塞米松在10-6~10-4mol/L浓度范围内可剂量依赖性地抑制甲状腺细胞增殖(P<0.05),增加甲状腺细胞凋亡率(P<0.05)及凋亡相关基因mRNA的表达(P<0.05)。结论 地塞米松可抑制甲状腺细胞增殖,促进甲状腺细胞凋亡的发生。

Abstract: Objective To investigate the effect of dexamethasone on apoptosis of primary human thyroid follicular epithelial cells. Methods After separation and stimulation with different concentrations of dexamethasone, inhibition rates of proliferation, apoptosis rates and apoptosis-related mRNA expression of primary thyroid follicular epithelial cells were measured by MTT, flow cytometry and fluorescence quantitative PCR respectively. Results Within the concentration range of 10-6~10-4mol/L, dexamethasone dose-dependently inhibited thyroid cell proliferation, increased cell apoptosis rates and expression of apoptosis-related mRNA of thyroid cells. Conclusion Dexamethasone can not only inhibit the proliferation of thyroid follicular epithelial cells, but also have effect on apoptosis of thyroid cells.
