摘要
目的:研究萝卜硫素对分化型甲状腺癌细胞NIS基因表达及摄碘能力的影响。方法:选择乳头状甲状腺癌细胞系K1及滤泡状甲状腺癌细胞系FTC133进行体外培养,给予不同浓度萝卜硫素处理24h,通过反转录实时荧光定量聚合酶链反应(RT-qPCR)检测钠/碘同向转运体(NIS)mRNA的表达;通过γ计数仪检测甲状腺癌细胞摄碘能力。结果:反转录实时荧光定量聚合酶链反应(RT-qPCR)检测结果表明,萝卜硫素可以上调NIS基因的表达,并呈浓度依赖性;γ计数仪检测结果表明,萝卜硫素可以提高分化型甲状腺癌的摄碘能力。结论:萝卜硫素为放射性碘治疗分化型甲状腺癌提供了新的思路。
Objective:To study the effect of Sulforaphane on sodium/iodide symporter gene expression and radioidide uptake of differentiated thyroid cancer cell line .Method:the thyroid cancer cell line K1 and FTC133 were treated with different concentrations of sulforaphane for 24h ,the expression level of NIS mRNA of K1 and FTC133 were determined by RT‐qPCR and their radioiodide concentration activity were measured by γ‐counter .Re‐sults :Sulforaphane can up‐regulate the expression of NIS in a dose‐dependent manner and also increase the ability of radioiodide concentration of differentiated thyroid cancer line .Conclusion:Sulforaphane provides a new idea for radio‐active iodine treatment of differentiated thyroid cancer .
