Bovine polymorphonuclear leukocytes exhibit a 12-lipoxygenase activity upon sonication. In contrast to bovine platelet 12-lipoxygenase and other 12-lipoxygenases, this enzyme is unable to convert 5(S)-HETE (5(S)-hydroxy,6-trans-8,11,14-cis-eicosatetr

A 226-nucleotide fragment was derived from alfalfa mosaic virus RNA 4 (ALMV RNA 4), the subgenomic messenger for viral coat protein, and its sequence was deduced by in vitro labeling with polynucleotide kinase and application of RNA sequencing techni

Incubation of bovine polymorphonuclear leukocytes (PMNs) with arachidonic acid leads to the formation of four lipoxins. The same lipoxins are also formed upon incubation of bovine PMNs with 5(S)-hydroperoxy-6-trans-8,11,14-cis-eicosatetraenoic acid,

A rapid and sensitive reversed-phase HPLC procedure is reported which allows the simultaneous separation and quantitation of LTC4, 11t-LTC4, LTD4, LTB4, 12epi,6t,8c-LTB4, 6t-LTB4 + 12epi,6t-LTB4, two trihydroxy-eicosatetraenoic acids tentatively iden

The leukotriene production by bovine polymorphonuclear leukocytes isolated from peripheral blood has been studied. Cells were incubated in the presence of arachidonic acid, glutathione, calcium ionophore A23187 and Ca2+. The leukotrienes then formed

In this study we present evidence for the existence of an intrinsic 12-lipoxygenase in the bovine polymorphonuclear leukocyte which differs from the well-known platelet 12-lipoxygenase. Intact bovine polymorphonuclear leukocytes synthesize predominan
