Abstract
Cardiovascular disease is the leading cause of mortality in patients with renal failure. Red blood cells (RBCs) are potential reservoirs for epoxy fatty acids (oxylipins) that regulate cardiovascular function. Hemoglobin exhibits pseudo-lipoxygenase activity in vitro. We previously assessed the impact of single hemodialysis (HD) treatment on RBC epoxy fatty acids status in circulating arterial blood and found that eicosanoids in oxygenated RBCs could be particularly vulnerable in chronic kidney disease and hemodialysis. The purpose of the present study was to evaluate the differences of RBC epoxy fatty acids profiles in arterial and venous blood in vivo (AV differences) from patients treated by HD treatment. We collected arterial and venous blood samples in upper limbs from 12 end-stage renal disease (ESRD) patients (age 72±12 years) before and after HD treatment. We measured oxylipins derived from cytochrome P450 (CYP) monooxygenase and lipoxygenase (LOX)/CYP ω/(ω-1)-hydroxylase pathways in RBCs by LC-MS/MS tandem mass spectrometry. Our data demonstrate arteriovenous differences in LOX pathway metabolites in RBCs after dialysis, including numerous hydroxyeicosatetraenoic acids (HETEs), hydroxydocosahexaenoic acids (HDHAs) and hydroxyeicosapentaenoic acids (HEPEs). We detected more pronounced changes in free metabolites in RBCs after HD, as compared with the total RBC compartment. Hemodialysis treatment did not affect the majority of CYP and CYP ω/(ω-1)-hydroxylase products in RBCs. Our data indicate that erythro-metabolites of the LOX pathway are influenced by renal-replacement therapies, which could have deleterious effects in the circulation.

Abstract
The aim of the study was to determine whether arachidonic acid (AA) is involved in the regulation of Sertoli cell lactate production and if this fatty acid participates in follicle-stimulating hormone (FSH) regulation of Sertoli cell function. In a first set of experiments the effect of AA and porcine pancreas phospholipase A2 (PLA2) on lactate production, glucose uptake, lactate dehydrogenase (LDH) activity and LDH A mRNA levels in Sertoli cell cultures obtained from 20-day-old rats was evaluated. In a second set of experiments the effect of two PLA2 inhibitors--quinacrine (Q) and AACOCF3--on FSH stimulation of the above-mentioned parameters of Sertoli cell function was investigated. Treatment with PLA2 and AA increased Sertoli cell lactate production. The observed action of exogenously added PLA2 involved its catalytic properties responsible for AA release. PLA2 and AA treatments also stimulated Sertoli cell glucose uptake, LDH activity and LDH A mRNA levels. In order to determine whether AA participates in FSH regulation of Sertoli cell lactate production cells were incubated with FSH in the absence or presence of the PLA2 inhibitors Q and AACOCF3. Both drugs partially inhibited the ability of FSH to stimulate lactate production, glucose uptake and LDH activity. The present investigation suggests that AA is involved in the regulation of lactate production, glucose transport, LDH activity and LDH A mRNA levels. In addition, these results suggest that cytosolic PLA2 and AA may participate in FSH-regulation of Sertoli cell energetic metabolism.

Abstract
We evaluated the levels of 15(S)-hydroxyeicosatetraenoic acid [15(S)-HETE] and the expression of 15-lipoxygenase (15-LO) mRNA in induced sputum obtained from 10 control and 15 chronic bronchitis subjects. 15(S)-HETE was evaluated by reverse phase high-performance liquid chromatography separation followed by specific RIA. 15-LO mRNA expression was determined by primed in situ labeling. The levels of both soluble and cell-associated 15(S)-HETE resulted significantly higher in chronic bronchitis than in control subjects. The percentage of cells expressing 15-LO mRNA was significantly higher in chronic bronchitis than in control subjects (P < 0.01). Double staining for specific cell type markers and 15-LO mRNA showed macrophages and neutrophils positive for 15-LO, whereas similar staining of peripheral blood neutrophils did not show evidence for 15-LO expression, suggesting that expression of 15-LO in neutrophils takes place on migration into the airways. Because 15(S)-HETE inversely correlated with the percentage of neutrophils in sputum of chronic bronchitis subjects, we studied the effect of 15(S)-HETE on leukotriene B(4) (LTB(4)) production in vitro and evaluated the concentration of LTB(4) in induced sputum and the contribution of LTB(4) to the chemotactic activity of induced sputum samples ex vivo. The results obtained indicate that macrophages and neutrophils present within the airways of chronic bronchitis subjects express 15-LO mRNA; increased basal levels of 15(S)-HETE may contribute to modulate, through the inhibition of 5-lipoxygenase metabolites production, neutrophil infiltration and airway inflammation associated with chronic bronchitis.

Abstract
Eicosatetraenoates (ETEs) with 5-oxo residues are known to induce human neutrophil (PMN) Ca2+ transients and chemotaxis. We find that 5-oxoETE, 5-oxo-8-trans-ETE, 5-oxo-15-hydroxy-ETE, 5-hydroxy-ETE, 5-hydroxy-15-oxoETE, 5,15-dioxoETE, and 5,15-dihydroxy-ETE have respective relative potencies of 10, 5, 3, 1, 0.2, 0.1, and 0.02 in: a) causing PMN to mobilize Ca2+, aggregate, and release small amounts of granule enzymes and b) promoting large degranulation and oxidative burst responses in PMN co-challenged with platelet-activating factor, tumor necrosis factor-alpha, or ATP. Contrastingly, 12(R)-hydroxy-ETE, 12(S)-hydroxy-ETE, and 12-oxoETE induced PMN Ca2+ transients and aggregation [respective potencies (5-hydroxy-ETE = 1) of 0.1, 0.01, and 0.003] but did not effect degranulation, and 15-hydroxy-ETE, 15-oxoETE, and 15-oxo-11-trans-ETE were inactive in all assays. Finally, 5-oxo/hydroxy-ETEs desensitized PMN to themselves but not to 12-oxo/hydroxy-ETEs or leukotriene (LT)B4; 12-oxo/hydroxy-ETEs and LTB4 desensitized PMN to themselves and each other but not to 5-oxo/hydroxy-ETEs; 15-oxo/hydroxy-ETEs did not desensitize PMN; and a LTB4 receptor antagonist blocked responses to LTB4 and 12-oxo/hydroxy-ETEs but not to 5-oxo/hydroxy-ETEs. Thus, 5-oxo/hydroxy-ETEs act by a common, LTB4 receptor-independent mechanism that recognizes 5- but not 12- or 15-oxo/hydroxy-ETEs and prefers oxo over hydroxy residues at C5 whereas 12-oxo/hydroxy-ETEs act via a LTB4 receptor mechanism that recognizes 12- but not 5- or 15-oxo/hydroxy-ETEs and prefers hydroxy over oxo residues at C12.

Abstract
LPS and mitogen-stimulated mononuclear cells secrete a cytokine, which is able to activate the PMNL-arachidonate-5-lipoxygenase. This cytokine has been proven to be identical with the recently characterized novel neutrophil-activating peptide NAP/IL-8. NAP/IL-8 is able to activate human PMNL for release of LTB4, omega-oxidized LTB4, and 5-HETE in the presence of exogenous AA. Half-maximal concentration of NAP/IL-8 for release of LTB4 has been found to be near 4 x 10(-8) mol/liter. Time course studies revealed rapid activation of PMNL, with maximal release of LTB4 within the first 10 min with a decline up to 40 min. High amounts of omega-oxidized LTB4 were detected up to that time. Significant amounts of AA-5-LO-products can be detected only when PMNL were stimulated with NAP/IL-8 in the presence of exogenous AA. The concentration of AA necessary for half-maximal LTB4 release has been found to be 3 x 10(-6) mol/liter. In the presence of 8 x 10(-9) mol/liter [3H]AA, NAP/IL-8 (10(-9) to 10(-7) mol/liter) did not induce the production of LTB4, omega-oxidized LTB4, or 5-HETE. In addition, PMNL prelabeled with [3H]AA did not release either [3H]AA or 5-lipoxygenase metabolites when stimulated with NAP/IL-8 (10(-9) to 10(-7) mol/liter), indicating that NAP/IL-8 apparently does not activate cellular phospholipases/diacylglycerol-lipases. Apart from FMLP, C5a, and PAF NAP/IL-8 is the fourth clearly characterized neutrophil chemotaxin able to activate the PMNL-5-lipoxygenase. The detection of large amounts of NAP/IL-8, arachidonic acid, as well as LTB4-like material, in lesional material of patients with psoriasis points towards a possibly important role of NAP/IL-8 in amplifying inflammatory processes by induction of LTB4-production.

Abstract
Lipoxygenase (LO) products generated by human PMN were examined utilizing a gradient-HPLC and rapid spectral detector which permitted continuous UV-spectral monitoring of leukotrienes, lipoxins and related oxygenated products of arachidonic acid. When exposed to the ionophore A23187, PMN generated LTB4 and its omega-oxidation products as well as LXA4, LXB4, and 7-cis-11-trans-LXA4 from endogenous sources. Addition of 15-HETE changed the profile of products generated by activated PMN and led to a time- and dose-dependent increase in lipoxins and related compounds while the production of LTB4 and its omega-oxidation products was inhibited. Results of time-course and radiolabel studies revealed that 15-HETE is rapidly transformed within 15 s to 5,15-DHETE and conjugated tetraene-containing products, and that the inhibition of leukotriene formation followed a similar time-course. In contrast, PMN did not generate either lipoxins or related products from 5-[3H]HETE, nor did 5-HETE block leukotriene formation. Stimulated PMN generated 5,15-DHETE from exogenous 5-HETE, while in the absence of ionophore, 5-HETE was transformed to 5,20-HETE. These results indicate that PMN can generate lipoxins and related products from endogenous sources and that 15-HETE and 5-HETE are transformed by different routes.

Abstract
Human neutrophils can aggregate, degranulate, and release mediators of inflammation including oxygen radicals and lipoxygenase (LO)-derived products of arachidonic acid. The regulation of 5- and 15-lipoxygenases appears to be important since their products (e.g. leukotrienes and lipoxins) display unique spectra of bioactions. Addition of 15-HETE, a product of the 15-LO, to neutrophils in suspension dramatically shifted the LO products generated and led to a dose-dependent increase in lipoxins, while the production of leukotriene B4 and its omega-oxidation products (i.e. 20-COOH-LTB4 and 20-OH-LTB4) was inhibited. Exogenous 15-HETE also dose-dependently inhibited the generation of superoxide anions induced by either the chemotactic peptide f-met-leu-phe or the divalent cation ionophore A23187. Neither lipoxin A4 nor lipoxin B4 (10(-8)-10(-6) M) inhibited O2-. generation induced by either f-met-leu-phe or A23187. These results indicate that in addition to serving as a substrate for lipoxin generation, 15-HETE also inhibits superoxide anion generation by human neutrophils. Together they provide further evidence to suggest that products of the 15-lipoxygenase may serve a regulatory role at inflammatory loci.

Abstract
Treatment of human synovial cell cultures with human recombinant interleukin 1 (IL-1) results in the appearance of activity in the supernatant which stimulates human polymorphonuclear neutrophils (PMNs), as assessed by increased chemokinesis and elevation of intracellular free calcium concentration. IL-1 (or related cytokines) were unable to stimulate these responses. This activity chromatographed as a single peak on C8 reversed-phase HPLC and subsequent size exclusion HPLC revealed two peaks of chemokinetic activity with apparent molecular masses of approximately equal to 13kDa and 6kDa. Fractions containing the higher molecular mass material also elevated PMN cytosolic free calcium. The local production of such factors may mediate IL-1-induced PMN accumulation in vivo.
