| Outline of Final Research Achievements |
It has been shown that ERK1/2 signaling pathway has protective role in the development of left ventricular (LV) remodeling after acute myocardial infarction (AMI). However, little is known about the role of negative regulator of ERK1/2 signaling pathway in the process of LV remodeling after AMI. We have shown that Sprouty4 (Spry4) is an intrinsic negative regulator of ERK1/2 signaling pathway in pathophysiology including angiogenesis. In this study, we determined whether ERK1/2 suppressor Spry4 would play a role in the development of LV remodeling after AMI.
The ERK1/2-Spry4 pathway is activated in the development of LV remodeling after AMI. The ERK1/2 phosphorylation and the LV remodeling after AMI are not different between Spry4-KO and WT mice. This study suggests that ERK1/2 suppressor Spry4 does not play an important role in the development of LV remodeling after AMI.
