Title Use of cell-based screening to identify small-molecule compounds that modulate claudin-4 expression.
Journal Biotechnol Lett
Abstract Claudins constitute a family of at least 27 proteins with four transmembrane domains, and play a pivotal role in maintaining tight-junctions seals in diverse epithelial tissues. The expression of claudin-4 often changes in intestinal tissues of inflammatory bowel disease and various human cancers. Therefore, claudin-4 is a promising target for treatment of these diseases. In our previous study, we established a reporter cell line to monitor claudin-4 expression on the basis of a functional claudin-4 promoter. Using this cell line, we have performed a cell-based screen of a library containing 2642 biologically active small-molecule compounds to identify modulators of claudin-4 expression. The screen identified 24 potential modulators of the claudin-4 promoter activity. Fourteen of these compounds (12 of them novel) induced endogenous claudin-4 expression. The identified compounds might serve as lead compounds targeting aberrant gene expression in inflammatory bowel disease.
