概括
可溶性神经素2 (sNRP2) 是神经内分泌瘤 (NEN) 的潜在预后生物标志物. 高sNRP2水平与较差的存活率相关,这表明它在侵略性NEN进展中的作用.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 生物标志物发现发现
背景情况:
- 神经素2 (NRP2) 涉及固体瘤和神经内分泌新生体 (NEN) 瘤发生.
- 一种可溶性形式,sNRP2,存在,但其在NEN中的预后价值仍未研究.
研究的目的:
- 调查可溶性神经素2 (sNRP2) 在神经内分泌瘤 (NENs) 的预后价值.
- 探索sNRP2水平与临床因素和NEN患者的整体存活率的相关性.
主要方法:
- 在瘤组织 (n=437) 和循环瘤细胞 (CTC) 中NRP2表达的免疫组织化学.
- 在NEN患者 (n=229) 和健康对照 (n=90) 中量化sNRP2水平的ELISA.
- 统计分析包括ROC和多变量生存分析.
主要成果:
- 在NEN (97%) 和神经内分泌癌 (NEC,74%) 中,NRP2的表达高,并且在所有研究的CTC中都存在.
- 异常的sNRP2水平与炎症综合征,转移和高染色素A水平有关.
- 在NEN患者中,高sNRP2水平显著预测了较差的整体存活率 (HR 0.16,P=0.015).
结论:
- 溶性NRP2 (sNRP2) 在NEN.中显示出作为预后生物标志物的潜力.
- 瘤和CTC中的NRP2表达表明它在NEN进展中的作用.
- sNRP2可能有助于识别激进的NEN并指导治疗策略.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Selectins

Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
