| Outline of Final Research Achievements |
Epithelial cell sheets form compartments that discriminate outer and inner environments and the apical-basal polarity of the epithelial cell is essential for the function. The mechanism of the formation and maintenance of the polarity, however, has not been fully understood. We made a basis for constructing a model that explains how the polarity is formed by quantitative measurements of protein amount along the cell cortex under normal or experimental conditions. Models containing the role of cell-cell and cell-substrate adhesions are under consideration. We also tried to identify important genes for polarity formation from genom-wide screening. After development of effective methods for measurement and analysis, we performed RNAi screening using more than 15,000 human genes. The results contained not only genes already reported but also new genes which involvement appears to be intriguing.
