| Outline of Final Research Achievements |
Renalase is a recently discovered flavin adenine dinucleotide (FAD) - dependent soluble monoamine oxidase. Its primary functions include catecholamine metabolism and blood pressure regulation. Renalase is predominantly expressed in the proximal tubule in the kidney. It is also expressed in other tissues, including the skeletal muscle, heart, and intestine.However, it remains unknown whether exercise could affect renalase expression.In this study, renalase expression in the skeletal muscle was increased by acute exercise, which was regulated by HIF-1α and NF-κB. In contrast, mRNA expression of Sp1 was unchanged in both the soleus and plantaris muscle following exercise when examining the contribution of catecholamine metabolic function in the skeletal muscle to renalase expression. In addition, renalase expression in the kidney was decreased by acute exercise.
