Outline of Final Research Achievements

p62 gene knockout mice exhibit obesity and metabolic syndrome due to hyperphagia. In this study, we analyzed sensitivity to ultraviolet irradiation induced apoptosis using p62-KO mice and primary cells isolated from mice. As a result, we found deletion of p62 cause apoptosis resistance in both in vitro and in vivo level. The enhancement of transcription factor Stat3 activity seems to be involved in this phenotype by inducing anti-apoptotic protein induction. These results suggest that p62 is a novel factor to regulate Stat3 activity.
