摘    要:研究了甲状腺素(T3/T4)及维甲酸(RA)对大鼠成骨样细胞ROS17/2.8细胞林甲状旁腺素(PTH)受体的调节作用.实验结果表明:细胞经T3/T4处理后,可显著增高PTH受体结合率及碱性磷酸酶活性,以及PTH受体mRNA的表达.细胞经RA处理后,则相反地降低PTH受体结合率及碱性磷酸酶活性.

关 键 词:甲状旁腺素受体  甲状腺素  维甲酸

Abstract:Parathyroid hormone (PTH) is a potent factor for bone resorption and bone cellmetabolism. The effect of thyroid hormone (T3/T4 ) and retinoic acid (RA) on the regulation ofPTH receptor(PTHR)was investigated. In osteoblast-like ROS 17/2. 8 cells, PTHR binding percentage, PTHR gene expression and alkaline phosphatase were up-regulated after treated with T3/T4 (10-10-10-6 mol/L); While it was down-regulated after treated with RA(10-10-10-5 mol/L). It is suggested that the regulation level of the "cross talk"among T3/T4, RA and PTH is onthe PTH receptor gene expression.
Keywords:Parathyroid hormone receptor  Thyroid hormone  Retinoic acid
