まとめ
慢性リンパ性甲状腺炎 (CLT) は,パピラ性甲状腺がん (PTC) の進行から保護することができます. BRAF V600Eの突然変異について
科学分野:
- エンドクリノロジーと腫瘍学
- 甲状腺病理学 甲状腺病理学
- 分子診断は分子診断です.
背景:
- 慢性リンパ性甲状腺炎 (CLT) は,甲状腺の炎症性疾患の中で最も一般的である.
- BRAF V600E変異は,パピラ性甲状腺がん (PTC) で頻繁に見られる遺伝子変異である.
- 彼らの相互作用を理解することは,PTCの行動を予測するために非常に重要です.
研究 の 目的:
- PTC.におけるCLTとBRAF V600E変異の関係を調査する.
- CLTとBRAF V600Eの組み合わせが,さまざまな腫瘍サイズで腫瘍の特徴に与える影響を評価する.
主な方法:
- 1474人のPTC患者の臨床および病理学的データの遡及的分析.
- 単変数および多変数ロジスティック回帰分析を使用した.
- 腫瘍の大きさに基づく分層分析が行われました.
主要な成果:
- CLTはPTC症例の27.5%に存在し,BRAF V600E変異,甲状腺外拡張,および進行段階と否定的に関連していました.
- BRAF V600E変異は,マイクロカルシノーマにおけるTNMの進行段階を独立して予測し,より大きな腫瘍における攻撃的特徴と関連していました.
- CLTなしのBRAF V600E変異の併用の存在は,進行したTNMステージと攻撃的な腫瘍行動と相関しています.
結論:
- CLTはPTCにおける保護的役割を果たし,小さながんの腫瘍進行を潜在的に抑制しているようです.
- BRAF V600E変異の予後的意義は,腫瘍のサイズに依存しています.
- より大きな腫瘍では,CLTの保護効果は,BRAF V600E変異によって引き起こされる攻撃的行動を克服するのに不十分かもしれません.

The Thyroid Gland
7.8K
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...

Functions of Thyroid Hormones
5.8K
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
8.0K
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...

Mutations

Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

Papillary Dermis

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
