Outline of Final Research Achievements

We examined the possible role of microRNA-21, which involved in Ras/ERK signaling pathway and its target gene Spry1, in angiotensin II-induced vascular senescence. In vitro, we observed that microRNA-21 was associated with angiotensin II-induced VSMC senescence together with its downstream target molecule. In vivo, we did not obtained the same results in this time. In future, it is necessary to investigate the interaction of microRNA-21 with vascular senescence using other senescent mouse models. We have not yet observed the possible involvement of Spry1 in the microRNA-21 associated VSMC senescence. In future, the examination of other molecules such as Sp-1 is needed.
