概括
TRPS1是一种可靠的标记物,用于识别初级乳腺神经内分泌瘤 (NETs),并将其与转移区分开来. 然而,它对于区分乳腺神经内分泌癌 (NEC) 与其他器官中类似癌症的区别并不那么有用.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 生物标志物研究 生物标志物研究
背景情况:
- 乳腺的原发性神经内分泌 (NE) 瘤很少见,难以诊断.
- 区分原发性乳腺NE瘤与其他器官的转移至关重要.
- TRPS1是乳腺起源的新发现标记物.
研究的目的:
- 为了研究TRPS1表达在原发性乳腺神经内分泌瘤 (NETs和NECs).
- 为了比较TRPS1表达的乳房NE瘤与肺部,胃肠道和胰腺的瘤.
- 评估TRPS1作为初级乳腺NE瘤的诊断标志物.
主要方法:
- 分析了105例神经内分泌瘤病例 (56例是乳腺,18例是肺,19例是胃肠道,12例是胰腺).
- 在所有情况下对TRPS1表达的免疫组织化学评估.
- 乳腺和非乳腺NE瘤之间的TRPS1染色模式的比较.
主要成果:
- 在97.4%的乳腺NET中,TRPS1表达高.
- 在23.5%的乳腺NEC中,TRPS1染色是微弱至中度的.
- 在肺或胰腺NE瘤中没有观察到TRPS1表达;只有一个胃肠NEC显示最小的阳性.
结论:
- TRPS1是区分原发性乳腺NET与肺部,胃肠道和胰腺的转移性NET的一个有价值的标志物.
- 在区分初级乳腺NEC与其他器官的NEC方面,TRPS1的实用性有限.
- 临床和放射相关性对于诊断原发性乳腺NEC至关重要.

86.0K
Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

13.2K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
