概括
较高的自由甲状腺 (FT4) 水平可以防止突然的神经感官听力损失 (SSNHL). 甲状腺刺激激素 (TSH) 水平似乎没有对SSNHL风险产生因果影响.
科学领域:
- 遗传学 是一个遗传学.
- 内分泌学 在内分泌学.
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
背景情况:
- 观察性研究表明甲状腺功能障碍和突然神经感官听力损失 (SSNHL) 之间存在联系.
- 甲状腺功能和SSNHL之间的确切因果关系尚不清楚.
- 门德尔随机化 (MR) 可以帮助阐明因果关系.
研究的目的:
- 研究甲状腺功能对SSNHL风险的因果关系.
- 采用双向和多变量门德尔随机化 (MR) 方法.
主要方法:
- 从欧洲个体的大型全基因组关联研究 (GWAS) 中为自由甲状腺 (FT4) 和甲状腺刺激激素 (TSH) 选择的单核酸多态 (SNPs).
- 利用了来自196,592名参与者的GWAS的SSNHL总结级数据.
- 应用了反变量加权 (IVW) 方法与灵敏度分析 (加权中位数,MR-Egger,MR-PRESSO).
主要成果:
- 基因预测FT4水平升高与SSNHL风险降低有关 (IVW:OR=0.747,P=0.04).
- 针对TSH的多变量MR调整证实了FT4的保护作用 (OR=0.929,P=0.036).
- 基因预测的TSH水平在任何方向都没有与SSNHL风险产生因果关系.
结论:
- 与更高FT4水平相关的遗传变异可能在正常范围内提供对SSNHL的保护.
- 在TSH水平和SSNHL风险之间没有直接的因果关系.

Synthesis and Regulation of Thyroid Hormones
4.6K
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

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...
