Cadherin-23 (Cdh23), a long-chain non-classical cadherin, exhibits strong homophilic and heterophilic binding. The physiological relevance of strong heterophilic binding with protocadherin-15 at neuroepithelial tip links is well-studied. However, the role of Cdh23 homodimers in physiology is less understood, despite its widespread expression at the cell boundaries of various human and mouse tissues, including kidney, muscle, testes, and heart. Here, we performed immunofluorescence studies that revealed that Cdh23 is present as distinct puncta at the cell-cell boundaries of cancer cells. Analysis of patient data and quantitative estimation of Cdh23 in human tissues (normal and tumor) also indicated that Cdh23 is down-regulated via promoter methylation in lung adenocarcinoma (AD) and esophageal squamous cell carcinoma (SCC) cells; we also observed a clear inverse correlation between Cdh23 expression and cancer metastasis. Using HEK293T cells and four types of cancer cells differentially expressing Cdh23, we observed that cell migration was faster in cells with reduced levels of Cdh23 expression. The cell migration rate in cancer cells is further accelerated by the presence of excretory isoforms of Cdh23, which loosen its cell-adhesion ability by competitive binding. Overall, our data indicate the role of Cdh23 as a suppressor of cell migration.

Non-profit plasmid repository dedicated to helping scientists around the world share high-quality plasmids. Facilitates archiving and distributing DNA-based research reagents and associated data to scientists worldwide. Repository contains over 65,000 plasmids, including special collections on CRISPR, fluorescent proteins, and ready-to-use viral preparations. There is no cost for scientists to deposit plasmids, which saves time and money associated with shipping plasmids themselves. All plasmids are fully sequenced for validation and sequencing data is openly available. We handle the appropriate Material Transfer Agreements (MTA) with institutions, facilitating open exchange and offering intellectual property and liability protection for depositing scientists. Furthermore, we curate free educational resources for the scientific community including a blog, eBooks, video protocols, and detailed molecular biology resources.
