| Outline of Final Research Achievements |
In this study, I attempted to elucidate the mechanism of the regulation of epithelial functions by the extracellular environment.
In MDCK cells, I revealed that claudin-2, transmembrane proteins in tight junctions, act as the sensor of the osmotic gradient between apical and basal sides to regulate several cell functions including transepithelial transport and cytoskeleton. Furthermore, I succeeded in establishing claudin-2 and claudin-4 double knockout cells and revealed the physiological role of claudin-4.
This study elucidates the mechanism in the epithelial cells to sense extracellular environment and regulate cell functions. This study also contributes to set a foundation for the clinical application for the cancer therapy in the future.
