u·vo·mo·ru·lin

(yū'vō-mō'rū-lin),
A transmembrane protein that links plasma membranes of adjacent cells together in a Ca2+-dependent manner; aids in maintaining the rigidity of the cell layer.
Synonym(s): E-cadherin
[L. uva, bunch of grapes, + Mod. L. morula, dim. of L. morum, fr. G. moron, mulberry, + -in]

CDH1

A gene on chromosome 16q22.1 that encodes a calcium-dependent cell–cell adhesion glycoprotein (cadherin), which is involved in regulating cell–cell adhesions, mobility and proliferation of epithelial cells.

Molecular pathology
CDH1 loss-of-function mutations correlate with gastric, breast, colorectal, thyroid and ovarian cancer, and they are thought to contribute to cancer progression by increasing proliferation, invasion and/or metastasis. CDH1 mutation causes hereditary diffuse gastric cancer and an increased susceptibility to endometrial and ovarian cancers.

E-cadherin

(e?kad-her'in, -her')
A molecule that makes cells adhere (stick to) each other. Many malignant tumor cells stop producing normal amounts of E-cadherin, which seems to contribute to their ability to move away from the location where the primary tumor arises and invade other tissues. See: cadherin

Adipose derived mesenchymal stem cells produce too much cytokines, bioactive matters, extracellular matrix proteins, as well as adhesion molecules (20).In a study, it has been shown that the co-culture with ADSCs increased both the N-cadherin and E-cadherin expression (27).
Initially, the results of the RNA quantification assay and Western blot analysis [Figure 4]a and [Figure 4]b demonstrated that miR-340 mimics or anti-ROCK-1 siRNA could increase E-cadherin and decrease ROCK-1, N-cadherin, and vimentin.

In view of the important role of EMT in tumor metastasis during tumor progression [19, 20], we explored the effect of DAB2IP on EMT progress and revealed that DAB2IP can modulate the expression of EMT marker E-cadherin and vimentin in AGS and SGC7901 gastric cancer cells.
Snail and Slug/Snail2 are important EMT-inducing transcription factors, which could directly bond and inhibit E-cadherin transcription, which mediates drug resistance [64].
However, it has been reported that diffuse GC as well as lobular breast carcinomas exhibited a reduced HER2 rate in comparison to frequent mutations of E-cadherin, with an inverse association [11, 22-24]; by contrast, in more than 50% of invasive cribriform breast carcinomas, a linear direct association between HER2 positivity and E-cadherin immunoreactivity has been already documented [25].
