まとめ
甲状腺ホルモンである遊離サイロキシン(FT4)および甲状腺ペルオキシダーゼ抗体(TPO-Ab)は、乳癌の発生および進行と関連している。FT4およびTPO-Abレベルの上昇は、乳癌のリスクおよび再発を予測する可能性がある。
科学分野:
- 内分泌学
- 腫瘍学
- バイオマーカー発見
背景:
- 甲状腺ホルモンは、細胞の代謝および成長において重要な役割を果たしている。
- 甲状腺機能の変化は様々な癌に関与していることが示唆されているが、乳癌におけるその特定の役割については、さらなる解明が必要である。
研究 の 目的:
- 血清甲状腺ホルモンレベルと乳癌患者の病理学的特徴との関連性を調査する。
- 乳癌における甲状腺ホルモンの診断および予測価値を評価する。
主な方法:
- 120名の乳癌患者および100名の健常対照者を対象とした後向き解析。
- 血清遊離トリヨードサイロニン(FT3)、遊離サイロキシン(FT4)、甲状腺刺激ホルモン(TSH)、サイログロブリン抗体(TG-Ab)、および甲状腺ペルオキシダーゼ抗体(TPO-Ab)の測定。
- 受信者操作特性(ROC)曲線分析および病理学的特徴との相関分析。
主要な成果:
- 乳癌患者は対照群と比較して、正常範囲内ではあったものの、血清FT4およびTPO-Abレベルが有意に高かった。
- ROC分析は、FT4(AUC=0.701)およびTPO-Ab(AUC=0.805)の良好な診断性能を示した。
- FT4およびTPO-Abレベルは、腫瘍の大きさ、臨床病期、リンパ節転移、およびホルモン受容体状態(ER/PR)と有意に関連していた。
結論:
- 血清FT4およびTPO-Abレベルは、乳癌の発生、進行、および病理学的特徴と密接に関連している。
- これらの甲状腺関連マーカーは、乳癌の診断および予測価値を示す。
- FT4およびTPO-Abは、乳癌の再発リスク評価のための潜在的なバイオマーカーとして機能する可能性がある。

Functions of Thyroid Hormones
4.9K
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...

Synthesis and Regulation of Thyroid Hormones
7.1K
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...

The Thyroid Gland
6.5K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Major Hormones and Their Functions
1.6K
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Hormones and Bone Tissue
3.6K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Target Cell Response to Hormones
5.0K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
