Synthesis and Regulation of Thyroid Hormones

4.8K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
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

2.9K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
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...

Regression Toward the Mean

6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

概括

较高的自由甲状腺素 (fT4) 水平可能会降低代谢综合征 (MetS) 的风险. 此外,高密度脂蛋白胆固醇 (HDL-C) 似乎影响甲状腺刺激激素 (TSH) 水平,这表明存在双向关系.

科学领域:

  • 内分泌学和新陈代谢学
  • 遗传学和基因组学 在
  • 心血管健康 心血管健康

背景情况:

  • 观察性研究表明甲状腺功能与代谢综合征 (MetS) 之间存在联系.
  • 这种关联背后的因果方向和机制仍然不清楚.
  • 研究遗传联系可以阐明这些关系.

研究的目的:

  • 为了确定甲状腺功能对METS风险的遗传预测因果影响.
  • 为了检查反向因果关系:MetS组件对甲状腺功能的影响.
  • 利用大规模的遗传关联数据进行可靠的分析.

主要方法:

  • 两个样本双向门德尔随机化 (MR) 研究.
  • 利用了来自全基因组综合关联研究 (GWAS) 的总结统计数据.
  • 分析了甲状腺刺激激素 (TSH),自由甲状腺素 (fT4),MetS及其成分 (腰围,禁食血糖,高血压,甘油三,HDL-C).

主要成果:

  • 较高的基因预测的自由甲状腺素 (fT4) 与降低的MetS风险相关 (OR = 0.96,P = .037).
  • fT4与高密度脂蛋白胆固醇 (HDL-C) 有正相关性 (β = 0.02,P = .008).
  • 基因预测的HDL-C显示出与TSH的负相关性 (β = -0.03,P = .046).
