Differentiation of HL-60 cells along the granulocytic lineage by DMSO in the presence of transforming growth factor-beta and low concentrations of 1,25-dihydroxyvitamin D3 leads to the upregulation of 5-lipoxygenase activity in 100,000 g supernatants and intact cells to levels which

1. Exogenous vasoactive intestinal polypeptide (VIP) infused into the pulmonary artery of isolated and ventilated lungs of guinea-pigs decreased, in a dose-dependent fashion (1.0-10.0 nmol), airway resistance and thromboxane B2 (TXB2, the stable hydrolysis product of TXA2) release in the
We have used stopped-flow rapid reaction methods, employing both fluorescence and absorbance monitoring, together with HPLC analysis of the products to study the activation of soybean 15-lipoxygenase by 13(S)-hydroperoxy-9, 11(E,Z)-octadecadienoic acid (13-HPOD). When lipoxygenase is mixed with an equimolar concentration
The role of arachidonic acid metabolites in the cardiac effects of toxic oxygen metabolites (TOM) was investigated in buffer-perfused rat hearts (Langendorff model). Hydrogen peroxide (H2O2, 200 microM) was given for 10 min to generate TOM, followed by 30 min
The proliferation of malignant hemopoietic cell lines is inhibited by antagonists of 5-lipoxygenase, suggesting that the endogenous generation of leukotrienes via the action of this enzyme may play some role in the proliferation of these cells (Snyder D. S., Castro
