| Outline of Final Research Achievements |
In mammals under cold-exposure stimulation, adipocytes change to be brown and to have thermogenic activity. However, it has not been discovered why only a part of adipocytes obtain the activity. In this study, we measured time-course gene expression of various adipose tissues under the stimulation. As the results of gene network analysis using the expression data, we elucidated that an inflammatory cytokine suppresses the browning of adipocytes. We also developed a method for predicting target genes of microRNAs that regulate the expression of the genes related to the adipocytes browning. In addition, we developed a method for the segmentation of adipocyte areas from the microscopic images of adipose tissues based on deep learning. The method was used for automatic and quantitative calculation of the areas of adipocytes to measure the change of their cell sizes by decomposing fat due to the browning.
