| Outline of Final Research Achievements |
More than 500 traits of the cell morphology quantified by image processing program CalMorph provide rich information of the cell, enabling us to predict the gene functions and the intracellular targets of drugs. In order to develop statistical models enabling us to analyze the complicated interactions among effects of drug treatments and gene disruptions, a generalized linear model was introduced into the phenotypic analysis of the cell morphology. Confounding factors affecting the cell morphology were identified and those effects were reduced by the linear model, enabling us to increase the statistical power to detect the interactions. By incorporating an interaction term into the linear models, the synergistic effects of drug-drug interaction or gene-drug interaction on the cell were successfully detected, supporting the feasibility of the analysis for the complicated interactions among the gene functions and the drug effects.
