概括

侵袭性叶状癌 (ILC) 中的E-cadherin异常即使没有CDH1基因变异也可能发生. 翻译后的修改是可能的原因,需要进一步研究CDH1-不变的ILC.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
遗传学遗传学是一种遗传学.

背景情况:

侵袭性叶状癌 (ILC) 具有独特的形态特征,通常与CDH1变化有关.
虽然已经研究了其他粘附因子,但CDH1-未改变ILC中E-cadherin异常的机制尚不清楚.

研究的目的:

研究在缺乏CDH1基因变异的侵袭性叶状癌中E-cadherin失调的分子机制.
为了比较CDH1-突变和非突变的ILC,以确定分子形状的差异.

主要方法:

进行了全面的生物信息分析.
对比研究包括对mRNA水平,逆相蛋白阵列 (RPPA),甲基化和微RNA (miRNA) 的评估.
侵袭性叶状腺癌病例根据CDH1突变状态进行了分层.

主要成果:

没有CDH1变化的侵袭性叶状腺癌病例显示,克劳丁低亚型的发病率显著更高 (p < 0.01).
RPPA结果显示CDH1-突变和非突变ILC之间的E-cadherin表达没有显著差异.
两组之间没有观察到mRNA水平或甲基化状态的显著差异.

结论:

在侵袭性叶状腺癌中存在E-cadherin异常,即使没有CDH1基因变异.
翻译后的修改是CDH1非突变ILC中E-cadherin失活的最合理的机制.
未来的研究应该集中于阐明翻译后修改在CDH1非突变ILC中E-cadherin无活化中的作用.

Cadherins in Tissue Organization

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Structure of Cadherins

Structure of Cadherins

The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

Adherens Junctions

Adherens Junctions

Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.
