Outline of Final Research Achievements |
It has been well known that lifestyle-related diseases like hypertension, metabolic syndrome, and diabetes are the risk of atrial fibrillation. We aimed to clarify the mechanism linking these pathological conditions and atrial arrhythmias using mice model, focusing on the involvement of microRNA (miR). We performed electrophysiological analysis and comprehensive expression analysis of miR, to identify the miRs playing a key role for atrial arrhythmias. We then performed thorough examination in metabolic syndrome model, and found that the expression of miR-27b was increased in atrium. The expression of Cx40, a major gap-junction channel in atrium was regulated by miR-27b. The increased expression of miR-27b caused the conduction disturbance, resulting in the higher inducibility of atrial tachyarrhythmias.
