用于治疗脏贫血的罗沙杜沙特可能会激活甲状腺激素受体 (TRα和TRβ). 这项研究发现,roxadustat在基于细胞的测定中激活了这些受体,这表明在临床剂量下具有潜在的甲状腺学活性.
科学领域:
- 内分泌学 在内分泌学.
- 药理学 药理学是指药理学的学科.
- 分子生物学分子生物学
背景情况:
- 罗沙杜沙特已被批准用于治疗脏贫血.
- 甲状腺激素受体 (TRα和TRβ) 调节代谢过程.
- 假设Roxadustat与TRs的潜在相互作用.
研究的目的:
- 为了研究roxadustat对TRα和TRβ激活的直接体外影响.
- 为了确定roxadustat是否在临床上相关的度下表现出甲状腺学活性.
主要方法:
- 细胞系 (U2OS,MCF-7,COS-7,Caco-2) 被 TRα 或 TRβ 和一个 luciferase 记者转移.
- 细胞在剥离或正常的人类血清中用roxadustat或triiodothyronine (T3) 进行化.
- 测量了露西法酶活性,以评估受体激活.
主要成果:
- 罗克萨杜沙特诱导了表达TRα或TRβ的细胞中的光酶活性.
- 这种激活发生在临床上可实现的roxadustat度.
- 罗沙杜沙特的效果与T3相似或大于T3,表明了显著的甲状腺仿制潜力.
结论:
- 在体外,Roxadustat可以直接激活TRα和TRβ.
- 临床相关度的罗沙沙斯塔特表现出甲状腺学作用.
- 医生应考虑roxadustat与甲状腺相关的潜在影响.

About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
