We have previously shown that ET-1 is highly up-regulated in renal tissues and in plasma after LPS administration. Here, we investigated whether landiolol hydrochloride, an ultra-short-acting beta-blocker, can play an important role in ameliorating levels of LPS-induced up-regulation of renal HIF-1α–ET-1 system and inflammatory cytokines in a rat model of endotoxemia. Main methods Male Wistar rats at 8 weeks of age were either administered with: a) lipopolysaccharide (LPS) only for three hours (3 h) or b) LPS, followed by continuous administration of landiolol for 3 h; c) third group was only treated with vehicle. Key findings At 3 h after LPS administration there was: a) minimal injury in kidney tissues; b) circulatory levels of creatinine, blood urea nitrogen and NGAL increased and c) expression of inflammatory cytokines, such as TNF-α, IL-6 and iNOS increased at the level of both circulatory and renal tissues. In addition, LPS significantly induced renal expression of ET-1 and HIF-1α compared to control. Finally, treatment of LPS-administered rats with landiolol for 3 h normalized elevated serum markers of renal injury and up-regulated levels of renal HIF-1α–ET-1 system with normalization of TNF-α. Significance Taken together, these data led us to conclude that landiolol ameliorates the up-regulation of HIF-1α–ET-1 system in minimally morphologically-injured kidney and normalizes biomarkers of renal injury in early hours of endotoxemia of a rat model.}, pages = {347--356}, title = {Potential amelioration of upregulated renal HIF-1alpha–endothelin-1 system by landiolol hydrochloride in a rat model of endotoxemia}, volume = {118}, year = {2014}, yomi = {オグラ, ヨシヤス and アライ, サブリナ and ヤマグチ, ナオト and シモジョウ, ノブタケ and カミヤマ, ジュンコ and サクラモト, ヒデアキ and ハギヤ, ケイイチ and カワノ, サトル and ミズタニ, タロウ} }
