| Outline of Final Research Achievements |
MicroRNAs (miRs) are increasingly associated with various diseases and biomechanisms, we studied serum miRs to find physical stress markers.To demonstrate changes in serum and cardiac miR levels when physical stress is applied, we constructed three stress modalities using rats: alcohol intake, treadmill running and restraint. As methods of miR measurement, qRT-PCR was performed after a microarray with serum. In addition, a comprehensive analysis using next-generation sequencing was performed in myocardium. This study showed that there are miRs whose expression level changes due to constraint stress after exercise.It was also suggested that different miRs were expressed depending on the different stress.
