Description:
The epoxyeicosatrienoic acids (EETs) are products of cytochrome P450 epoxygenases that have vasodilatory properties similar to that of endothelium-derived hyperpolarizing factor. The cytochrome P450 isoform CYP2J2 was cloned and identified as a potential source of EETs in human endothelial cells. Physiological concentrations of EETs or overexpression of CYP2J2 decreased cytokine-induced endothelial cell adhesion molecule expression, and EETs prevented leukocyte adhesion to the vascular wall by a mechanism involving inhibition of transcription factor NF-kappaB and IkappaB kinase. The inhibitory effects of EETs were independent of their membrane-hyperpolarizing effects, suggesting that these molecules play an important nonvasodilatory role in vascular inflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2720027/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2720027/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Node, K -- Huo, Y -- Ruan, X -- Yang, B -- Spiecker, M -- Ley, K -- Zeldin, D C -- Liao, J K -- HL-52233/HL/NHLBI NIH HHS/ -- HL-58108/HL/NHLBI NIH HHS/ -- P01 HL048743/HL/NHLBI NIH HHS/ -- P01 HL048743-080008/HL/NHLBI NIH HHS/ -- P01 HL048743-090008/HL/NHLBI NIH HHS/ -- R01 HL052233/HL/NHLBI NIH HHS/ -- R01 HL052233-05/HL/NHLBI NIH HHS/ -- R01 HL052233-06/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1999 Aug 20;285(5431):1276-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vascular Medicine and Atherosclerosis Unit, Cardiovascular Division, Brigham and Women's Hospital and Harvard Medical School, 221 Longwood Avenue, LMRC-322, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10455056" target="_blank"〉PubMed〈/a〉
