Sevoflurane inhibits angiotensin II-induced Rho kinase-mediated contraction of vascular smooth muscle from spontaneously hypertensive rat
Purpose Angiotensin II (Ang II)-induced vasoconstriction is mediated by changes in intracellular free Ca 2+ concentration ([Ca 2+ ] i ) and myofilament Ca 2+ sensitivity. Protein kinase C- and Rho kinase-mediated signaling pathways are proposed for the regulation of the Ca 2+ sensitization mechanism...

Angiotensin II (Ang II)-induced vasoconstriction is mediated by changes in intracellular free Ca
2+
concentration ([Ca

i
) and myofilament Ca
2+
sensitivity. Protein kinase C- and Rho kinase-mediated signaling pathways are proposed for the regulation of the Ca
2+
sensitization mechanisms. We have demonstrated that sevoflurane inhibits Rho kinase-mediated contraction of isolated rat aortic smooth muscle. A recent study demonstrated that Rho-kinase mediated Ca
2+
sensitization was involved in the pathophysiology of hypertension. This study was designed to investigate the effects of sevoflurane on Ang II-induced Rho kinase-mediated vascular contraction in spontaneously hypertensive rats (SHR).
Methods
The effects of sevoflurane on vasoconstriction, increase in [Ca

i
, and membrane translocation of Rho kinase in response to Ang II were investigated in normotensive Wistar–Kyoto rats (WKY) and SHR, using an isometric force transducer, a fluorometer, and Western blotting, respectively.
Results
The inhibitory effects of sevoflurane on Ang II (10

Results
The inhibitory effects of sevoflurane on Ang II (10

P
< 0.05) in SHR than in WKY at the highest concentration of sevoflurane (5.1%). Y27632 (3 × 10

Conclusions
These findings suggest that the inhibition of the Ang II-induced contraction by sevoflurane in SHR may be, at least in part, due to the attenuation of the Rho kinase-mediated signaling pathway.</description><identifier>ISSN: 0913-8668</identifier><identifier>EISSN: 1438-8359</identifier><identifier>DOI: 10.1007/s00540-011-1121-8</identifier><identifier>PMID: 21409351</identifier><language>eng</language><publisher>Japan: Springer Japan</publisher><subject>Amides - pharmacology ; Anesthesiology ; Anesthetics ; Anesthetics, Inhalation - pharmacology ; Angiotensin ; Angiotensin II - antagonists & inhibitors ; Angiotensin II - pharmacology ; Animals ; Aorta, Thoracic - drug effects ; Blood Pressure - drug effects ; Calcium - metabolism ; Calcium Signaling - drug effects ; Critical Care Medicine ; Emergency Medicine ; Enzyme Inhibitors - pharmacology ; Hypertension ; In Vitro Techniques ; Intensive ; Isometric Contraction - drug effects ; Male ; Medicine ; Medicine & Public Health ; Methyl Ethers - pharmacology ; Muscle Contraction - drug effects ; Muscle, Smooth, Vascular - drug effects ; Original Article ; Pain Medicine ; Protein Transport ; Pyridines - pharmacology ; Rats ; Rats, Inbred SHR ; Rats, Inbred WKY ; rho-Associated Kinases - antagonists & inhibitors ; Sevoflurane ; Smooth muscle</subject><ispartof>Journal of anesthesia, 2011-06, Vol.25 (3), p.398-404</ispartof><rights>Japanese Society of Anesthesiologists 2011</rights><rights>COPYRIGHT 2011 Springer</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c567t-8a434c4fa6f76cbba3b502c77b65038e0794e34b143da0b68420a1aedcafd2ca3</citedby><cites>FETCH-LOGICAL-c567t-8a434c4fa6f76cbba3b502c77b65038e0794e34b143da0b68420a1aedcafd2ca3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/21409351$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Uematsu, Nobuhiko</creatorcontrib><creatorcontrib>Ogawa, Koji</creatorcontrib><creatorcontrib>Tokinaga, Yasuyuki</creatorcontrib><creatorcontrib>Tange, Kazuaki</creatorcontrib><creatorcontrib>Hatano, Yoshio</creatorcontrib><title>Sevoflurane inhibits angiotensin II-induced Rho kinase-mediated contraction of vascular smooth muscle from spontaneously hypertensive rat</title><title>Journal of anesthesia</title><addtitle>J Anesth</addtitle><addtitle>J Anesth</addtitle><description>Purpose
