Introduction About E-cadherin (CDH1): Drug Target and Biomarker
E-cadherin plays a crucial role in cell-cell adhesion and is involved in the regulation of cell proliferation, differentiation, and apoptosis in gastrointestinal epithelial cells.
The transcription of E-cadherin, beta-catenin, and alpha-catenin genes can be activated by T3 (thyroid hormone) in differentiating epithelial cells, promoting cell differentiation and reducing the oncogenic effects.
TH-TRalpha1 directly binds to the beta-catenin gene and increases its expression, while TRbeta-RXR complexes mediate CTNNB1 (beta-catenin) transrepression.
T3 can activate PKA to induce beta-catenin nuclear translocation, thereby modulating cyclin-D1 gene transcription and promoting cell proliferation.
E-cadherin-mediated cell-cell adhesion involves activation of the PI3K-Akt pathway, which influences membrane and actin dynamics, and reduces Rho activation.
E-cadherin downregulates receptor tyrosine kinase activation and stabilizes cell-cell contacts.
Pathogenic bacteria can cleave E-cadherin at specific sites, leading to the release of soluble extracellular E-cadherin fragments.
The Rho/ROCK/E-cadherin cascade and Galphai/o and Galpha11/q-dependent signaling cascades are involved in mediating the effects of LPA (lysophosphatidic acid) on cell motility, with the Rho/ROCK pathway being the predominant pathway.
Overall, E-cadherin is essential for cell-cell adhesion and is regulated by various signaling pathways. Its expression and function are influenced by thyroid hormones and can impact cell proliferation, differentiation, and apoptosis. E-cadherin also plays a role in maintaining cell-cell contacts and modulating cell motility.
Based on the given context information, the keyword "E-cadherin" (synonymous with CDH1) is associated with several important functions and signaling pathways in cell adhesion and regulation.
Firstly, E-cadherin forms stable adherens junctions, enabling strong cell-to-cell contact. These junctions play a role in suppressing the activation of the Wnt/beta-catenin pathway and the RTK/PI3K pathway in epithelial cells. E-cadherin expression promotes the extranuclear translocation of beta-catenin, suppressing the Wnt pathway.
In non-epithelial cells, N-cadherin-mediated adherens junctions facilitate cell survival and migration by activating the MAPK/ERK pathway and the PI3K pathway in association with PDGFR. This activation enhances cell survival and migration.
Additionally, the loss of E-cadherin expression has been associated with the acquisition of metastatic characteristics in breast cancer cells. Distinct complexes called Ring1b complexes can cause epigenetic changes on the E-cadherin promoter, leading to the silencing of E-cadherin and the acquisition of metastatic properties.
Moreover, the cadherin-catenin complex at mature adherens junctions is involved in signaling events to the nucleus. In conditions that alter E-cadherin-mediated adhesion, such as phosphorylation, endocytosis, or loss of E-cadherin expression, beta-catenin and p120 can bind their nuclear effectors. This binding can modulate the expression of specific target genes, including Wnt target genes.
Lastly, CDH1 (E-cadherin) plays a role in cell cycle regulation. Under normal conditions, CDH1 degrades SAG at the G1 phase but inhibits APC/C at the M phase, ensuring timely cell cycle progression. Alterations in SAG levels can disrupt this regulation and may lead to accelerated cell cycle progression, drug resistance, or aberrant mitotic progression.
In summary, E-cadherin, or CDH1, is involved in cell adhesion, regulation of signaling pathways (such as Wnt/beta-catenin and RTK/PI3K), acquisition of metastatic properties, regulation of target gene expression, and cell cycle progression.
Protein Name: Cadherin 1
Functions: Cadherins are calcium-dependent cell adhesion proteins (PubMed:11976333). They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. CDH1 is involved in mechanisms regulating cell-cell adhesions, mobility and proliferation of epithelial cells (PubMed:11976333). Has a potent invasive suppressor role. It is a ligand for integrin alpha-E/beta-7
