摘要
对4种甲状腺癌细胞株予全反式维甲酸处理,四甲基偶氮唑盐法检测细胞增殖,同位素法测定摄碘功能,半定量RT-PCR检测甲状腺特异基因及维甲酸受体表达。结果显示全反式维甲酸可抑制FTC-133细胞增殖,促进其摄碘及甲状腺特异基因的表达,但对C643、HTH74及XTC.UC1细胞无影响,提示不同甲状腺肿瘤细胞对全反式维甲酸的反应性不相同。
Different human thyroid carcinoma cell lines were treated with all-trans retinoic acid (RA). RA could inhibit cell growth, improve iodide uptake and increase some thyroid specific genes and retinoid acid receptor (RAR) mRNA expressions in FTC-133 cells. However, RA had no effect in C643, HTH74 and XTC- UC1 cells. These findings indicate that different thyroid carcinoma cells display diverse responses to RA.
