Abstract
In this study, the effects of l-arginine-nitric-oxide (∙NO)-producing pathway on protein content of ubiquitin, as an important component of ubiquitin–proteasome system for protein removal, were investigated. We showed that l-arginine markedly decreased ubiquitin protein content in interscapular brown adipose tissue, both in thermogenic inactive (at room temperature) and thermogenic active (on cold) states; while in l-NAME-treated groups this effect was abolished. This result suggests that nitric oxide (∙NO), besides well established roles, is involved in this aspect of structure remodeling, as well.
