| Outline of Final Research Achievements |
Previous studies have shown that the morphological changes such as vascular disorder in the inner ear of patients with hearing loss. However, the cause has not been clarified. In this study, molecular biological analysis using the inner ear of metabolic syndrome model animals was performed. As a result, increased expression of inflammatory cytokines, lipid metabolism-related proteins, and decreased expression of growth factors were observed. In addition, we constructed an experimental model that can investigate the relationship between diabetes and inner ear tissue change by culturing the inner ear tissues of experimental animals in hyperglycemic state.
