It is well documented that nitric oxide (NO.) also stimulates the trans-regulatory activity of IRP-1 and consequently disturbs iron homeostasis in various cellular systems exposed to inflammatory conditions (3). R., and Walden, W. C. (1997) Biochem. After 18 h of incubation, cells from one set of flasks were stimulated with PMA for an additional 3 and 6 h, whereas cells in the second set of flasks were

Do not start a new topic. After 24 h, nitrite production was measured in cell culture medium, and aconitase activity, as well as nitration of IRP-1, was determined in cell cytosols. After 2 h on ice and in the dark, the magnetically labeled immune complex was bound to a column placed in a magnetic field, and after several washings the immunoprecipitated IRP-1 These results point to nitration as an event downstream of [Fe-S] disruption and therefore of aconitase loss.

However, when PMA was added along with IFN-γ/LPS, IRP-1 was far less potent in binding IRE (Fig. 4A, upper panel, compare lane 2 with lane 3). Parallel control studies demonstrated that 1 mm cis-aconitate did not inhibit nitration of bovine serum albumin induced by 25 μm peroxynitrite. A. (2002) Proc.

Similarly, it has been reported that endogenous nitration of peroxisome proliferator-activated receptor-γ inhibited its ligand-dependent translocation from cytosol to nucleus in LPS-stimulated RAW 264.7 macrophages (38). Because IRP-1 is a sensitive target protein for nitric oxide (NO), we investigated whether this protein is nitrated in inflammatory macrophages and whether this post-transcriptional modification changes its activities.

Soum for excellent work on analysis of protein-bound nitrotyrosine by enzyme-linked immunosorbent assay and to Dr. Indeed, in vitro studies previously showed that redox metals, particularly iron, can catalyze protein tyrosine nitration promoted by peroxynitrite (42) or by nitrite/H2O2 (41, 43).

IRP-1 is a bifunctional metalloprotein in which the aconitase and IRE-binding activities are mutually exclusive, depending on the presence or absence of its [4Fe-4S] cluster (1). The skillful technical assistance of M. Accordingly, we speculate that prevention of IRP-1 activation by nitration in macrophages during inflammatory processes might be an intrinsic protective mechanism against the noxious effect of iron through Fenton-like reactions. mfesmfk;c:\windows\system32\drivers\mfesmfk.sys [2009-3-6 40552]=============== Created Last 30 ================2010-01-29 17:02:52 0 dc----w- c:\docume~1\alluse~1\applic~1\{C4C0E335-EDDF-46A0-A57D-F3802AE44275}2010-01-29 16:37:45 0 d-----w- c:\windows\system32\XPSViewer2010-01-29 16:37:02 216 ----a-w- c:\windows\system32\spupdsvc.inf2010-01-29 16:36:28 89088 ------w- c:\windows\system32\dllcache\filterpipelineprintproc.dll2010-01-29 16:36:28 597504 ------w- c:\windows\system32\dllcache\printfilterpipelinesvc.exe2010-01-29 16:36:28 575488 ------w- c:\windows\system32\xpsshhdr.dll2010-01-29

Biol. IRP-1 was isolated from cytosols by immunoprecipitation, and its nitration was detected by Western blot analysis using a polyclonal nitrotyrosine antibody. We first stimulated macrophages with IFN-γ/LPS for several hours to allow NO synthase-2 to be both expressed and functional and then we exposed NO-producing macrophages to PMA to stimulate generation via Jr.

Remarkably, this impairment of IRP-1 in binding the IRE motif correlated with the strongest IRP-1 nitration (compare Fig. 3C with Fig. 4A).
