概括

血管活性肠 (VIP) 与癌症相关基因,特别是ZEB1显著相关,这表明它在表皮-介质细胞过渡 (EMT) 中的作用. 这突出了VIP作为ZEB1介导的EMT在各种癌症中的潜在生物标志物.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
基因组学就是基因组学.

背景情况:

血管活性肠 (VIP) 是一种激素,在癌症和健康组织中发现,包括神经系统和消化道.
虽然VIP及其受体存在于许多癌症中,但其在自身隐性信号传递和作为预后生物标志物的作用尚不清楚.
了解VIP在癌症中的作用可能会揭示新的治疗点和诊断工具.

研究的目的:

通过 in silico 基因表达分析,研究癌症中自身隐性 VIP 信号传递的机制.
为了确定与癌症相关的基因与VIP表达有显著的相关性.
探索VIP作为瘤学中的预后和预测生物标志物的潜力.

主要方法:

在癌症基因组图谱 (TCGA) PANCAN组织样本的基因表达分析.
使用皮尔森的R系数,对VIP表达和760个癌症相关基因之间的相关性分析.
基因组丰富分析以确定与VIP信号相关的途径.

主要成果:

十个基因,包括ZEB1,MAPK3和TIMELESS,在所有分析的癌症类型中显示出与VIP表达具有统计学意义的关联 (P <0.05).
作为表皮-介质细胞转换 (EMT) 的关键调节者,ZEB1与VIP的正相关性最强,特别是在胃肠道癌症中.
在健康的胃肠组织中,VIP和ZEB1的表达也与积极相关,高的共同表达与增加的肌肉积分有关.

结论:

在癌症中,VIP信号与EMT和细胞循环途径有关.
对于ZEB1介导的EMT,VIP可以作为一个有价值的生物标志物.
需要进一步的研究来阐明VIP-ZEB1相互作用在癌症生物学中的精确机制.

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

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.

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
