| Outline of Final Research Achievements |
We have investigated the role of the transcription factor KLF15 in the regulation of systemic metabolism. The abundance of KLF15 in skeletal muscle is upregulated in response to exercise, which is likely mediated via calcium-dependent signaling. The abundance of KLF15 in skeletal muscle is also upregulated in several diabetic model mice and treatment of cultured muscle cells with a high concentration of glucose resulted in the increase in the protein abundance of the transcription factor. Hyperglycemia-induced increase in the protein abundance of KLF15 is attributable to the decrease in the poly-ubiquitination of this protein. Whereas blood glucose levels of muscle-specific KLF15 deficient mice are similar to those of control mice, those of the mutant mice at fasting states are lower, suggesting that KLF15 in skeletal muscle contribute to the regulation of hepatic gluconeogenesis.
