まとめ
研究者らは、尿中のタンパク質を分析することにより、頭頸部扁平上皮癌(HNSCC)の潜在的な早期発見バイオマーカーを特定した。この非侵襲的なプロテオゲノムアプローチは、HNSCCの管理と早期診断に有望である。
科学分野:
- 泌尿器科学
- 腫瘍学
- プロテオミクス
背景:
- 頭頸部扁平上皮癌(HNSCC)は、その攻撃的な挙動と進行期における予後不良が特徴であり、臨床的に大きな課題となっている。
- 診断の遅れはしばしば早期発見の遅れにつながり、HNSCCに対する治療介入の効果を制限する。
- 患者の転帰を改善するために、HNSCCの早期発見のための改善された方法に対する重大な必要性が存在する。
研究 の 目的:
- HNSCCの早期発見における尿プロテオゲノミクスの可能性を調査すること。
- HNSCCに関連する尿中の新規タンパク質バイオマーカーを同定すること。
- HNSCCの分子プロファイリングのための非侵襲的媒体としての尿の使用の実現可能性を探ること。
主な方法:
- 男性HNSCC患者および健常男性被験者から採取した尿サンプルを質量分析ベースのプロテオミクスを用いて分析した。
- 尿サンプルで検出されたタンパク質の同定と比較定量。
- 同定されたペプチドとがんバリアントデータベースのプロテオゲノムクロスリファレンス。
- 腫瘍関連プロセスにおけるそれらの役割を理解するための同定されたタンパク質の機能分析。
主要な成果:
- 尿中で1427種類のタンパク質が同定され、351種類が全被験者で一貫して検出された。
- RNASE1、LRG1、CD44などの潜在的な予後マーカーが強調された。
- HNSCC関連タンパク質バリアント(例:GAA p.(Trp746Cys)、SIAE p.(Pro210Leu))が尿中で検出され、進行性疾患の潜在的な指標を示唆した。
- 同定されたタンパク質は、上皮間葉転換や好中球脱顆粒などの重要な腫瘍プロセスに関連していた。
結論:
- 尿は、HNSCCにおける非侵襲的なプロテオゲノムプロファイリングのための実行可能な生体液である。
- 尿プロテオゲノミクスは、早期HNSCC検出のためのバイオマーカー開発のための有望な道を提供する。
- HNSCC管理におけるこれらの発見の特異性と臨床的有用性を確認するためには、より大規模で多様なコホートでのさらなる検証が必要である。

Arteries of the Head and Neck
3.3K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Veins of Head and Neck
5.6K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Muscles of the Anterior Neck
4.8K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Muscles that Move the Head
6.0K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Introduction to Urinary System
9.1K
The urinary system consists of two kidneys, two ureters, the urinary bladder, and the urethra.
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...

Urinary Bladder
3.5K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
