Abstract
ABSTRACT Sepsis after a major hepatectomy is a critical problem. In septic shock, the inflammatory mediator, nitric oxide (NO), is overproduced in hepatocytes and macrophages. The natural antisense (AS) transcripts, non-coding RNAs, are transcribed from a gene that encodes inducible nitric oxide synthase (iNOS). iNOS AS transcripts interact with and stabilize iNOS mRNAs. A single-stranded "sense oligonucleotide" (designated as SO1) corresponding to the iNOS mRNA sequence inhibits mRNA-AS transcript interactions and reduces iNOS mRNA levels in rat hepatocytes. In contrast, recombinant human soluble thrombomodulin (rTM) treats disseminated intravascular coagulopathy by suppressing coagulation, inflammation, and apoptosis. In this study, the combination therapy of SO1 and a low dose of rTM was evaluated for hepatoprotection in a rat septic shock model after partial hepatectomy. Rats underwent 70% hepatectomy, followed by intravenous (i.v.) injection of lipopolysaccharide (LPS) after 48 h. SO1 was injected (i.v.) simultaneously with LPS, whereas rTM was injected (i.v.) 1 h before LPS injection. Similarly to our previous report, SO1 increased survival after LPS injection. When rTM, which has different mechanisms of action, was combined with SO1, it did not interfere with the effect of SO1 and showed a significant increase in survival compared with LPS alone treatment. In serum, the combined treatment decreased NO levels. In the liver, the combined treatment inhibited iNOS mRNA and protein expression. A decreased iNOS AS transcript expression by the combined treatment was also observed. The combined treatment decreased mRNA expression of the inflammatory and pro-apoptotic genes while increasing that of the anti-apoptotic gene. Furthermore, the combined treatment reduced the number of myeloperoxidase-positive cells. These results suggested that the combination of SO1 and rTM has therapeutic potential for sepsis.

Abstract
Natural antisense transcripts (asRNAs) that do not encode proteins are transcribed from rat, mouse, and human genes, encoding inducible nitric oxide synthase (iNOS), which catalyzes the production of the inflammatory mediator nitric oxide (NO). In septic shock, NO is excessively produced in hepatocytes and macrophages. The iNOS asRNA interacts with and stabilizes iNOS mRNA. We found that single-stranded 'sense' oligonucleotides corresponding to the iNOS mRNA sequence reduced iNOS mRNA levels by interfering with the mRNA-asRNA interactions in rat hepatocytes. The iNOS sense oligonucleotides that were substituted with phosphorothioate bonds and locked nucleic acids efficiently decreased the levels of iNOS mRNA and iNOS protein. In this study, the gene expression patterns in the livers of two endotoxemia model rats with acute liver failure were compared. Next, we optimized the sequence and modification of the iNOS sense oligonucleotides in interleukin 1β-treated rat hepatocytes. When a sense oligonucleotide was simultaneously administered with d-galactosamine and bacterial lipopolysaccharide (LPS) to rats, their survival rate significantly increased compared to the rats administered d-galactosamine and LPS alone. In the livers of the sense oligonucleotide-administered rats, apoptosis in the hepatocytes markedly decreased. These results suggest that natural antisense transcript-targeted regulation technology using iNOS sense oligonucleotides may be used to treat human inflammatory diseases, such as sepsis and septic shock.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disease. Currently, there are no therapies to stop or reverse the symptoms of AD. We have developed an antisense oligonucleotide (OL-1) against the amyloid-β protein precursor (AβPP) that can decrease AβPP expression and amyloid-β protein (Aβ) production. This antisense rapidly crosses the blood-brain barrier, reverses learning and memory impairments, reduces oxidative stress, and restores brain-to-blood efflux of Aβ in SAMP8 mice. Here, we examined the effects of this AβPP antisense in the Tg2576 mouse model of AD. We administered the OL-1 antisense into the lateral ventricle 3 times at 2week intervals. Seventy-two hours after the third injection, we tested learning and memory in T-maze foot shock avoidance. In the second study, we injected the mice with OL-1 antisense 3 times at 2-week intervals via the tail vein. Seventy-two hours later, we tested learning and memory T-maze, novel object recognition, and elevated plus maze. At the end of behavioral testing, brain tissue was collected. OL-1 antisense administered centrally improved acquisition and retention of T-maze foot shock avoidance. OL-1 antisense administered via tail vein improved learning and memory in both T-maze foot shock avoidance and novel object-place recognition. In the elevated plus maze, the mice which received OL-1 antisense spent less time in the open arms and had fewer entries into the open arms indicating reduced disinhibitation. Biochemical analyses reveal significant reduction of AβPP signal and a reduction of measures of neuroinflammation. The current findings support the therapeutic potential of OL-1 AβPP antisense.

Abstract
In this work, multifunctional biosynthetic hybrid nanostructures were prepared and studied for their potential utility in the recognition and inhibition of mRNA sequences for inducible nitric oxide synthase (iNOS), which are overexpressed at sites of inflammation, such as in cases of acute lung injury. Shell cross-linked knedel-like polymer nanoparticles (SCKs) that present peptide nucleic acids, for binding to complementary mRNAs, and cell penetrating peptides (CPPs), to gain cell entry, along with fluorescent labels and sites for radiolabeling, were prepared by a series of robust, efficient, and versatile synthetic steps that proceeded from monomers to polymers to functional nanoparticles. Amphiphilic block graft copolymers having combinations of methoxy- and thioacetyl-terminated poly(ethylene glycol) (PEG) and DOTA-lysine units grafted from the backbone of poly(acrylic acid) (PAA) and extending with a backbone segment of poly(octadecyl acrylate-co-decyl acrylate) (P(ODA-co-DA)) were prepared by a combination of reversible addition-fragmentation chain transfer (RAFT) polymerization and chemical modification reactions, which were then used as the building blocks for the formation of well-defined SCKs decorated with reactive thiols accessible to the surface. Fluorescent labeling with Alexa Fluor 633 hydrazide was then accomplished by amidation with residual acrylic acid residues within the SCK shells. Finally, the PNAs and CPP units were covalently conjugated to the SCKs via Michael addition of thiols on the SCKs to maleimide units on the termini of PNAs and CPPs. Confirmation of the ability of the PNAs to bind selectively to the target iNOS mRNAs when tethered to the SCK nanoparticles was determined by in vitro competition experiments. When attached to the SCKs having a hydrodynamic diameter of 60 ± 16 nm, the K(d) values of the PNAs were ca. an order of magnitude greater than the free PNAs, while the mismatched PNA showed no significant binding.

Abstract
Gangrenous dermatitis (GD) is an emerging disease of increasing economic importance in poultry resulting from infection by Clostridium septicum and Clostridium perfringens type A. Lack of a reproducible disease model has been a major obstacle in understanding the immunopathology of GD. To gain better understanding of host-pathogen interactions in GD infection, we evaluated various immune parameters in two groups of birds from a recent commercial outbreak of GD, the first showing typical disease signs and pathological lesions (GD-like birds) and the second lacking clinical signs (GD-free birds). Our results revealed that GD-like birds showed: reduced T-cell and B-cell mitogen-stimulated lymphoproliferation; higher levels of serum nitric oxide and alpha-1-acid glycoprotein; greater numbers of K55(+), K1(+), CD8(+), and MHC class II(+) intradermal lymphocytes, and increased K55(+), K1(+), CD8(+), TCR1(+), TCR2(+), Bu1(+), and MHC class II(+) intestinal intraepithelial lymphocytes; and increased levels of mRNAs encoding proinflammatory cytokines and chemokines in skin compared with GD-free chickens. These results provide the first evidence of altered systemic and local (skin and intestine) immune responses in GD pathogenesis in chickens.

Abstract
The peptidyl-proline isomerase Protein Never in Mitosis Gene A Interacting-1 (PIN1) increases the level or activity of several transcription factors that can induce the inducible nitric oxide (NO) synthase (iNOS). PIN1 can also regulate mRNA and protein turnover. Here, the effect of depletion of PIN1 on induction of iNOS by Escherichia coli endotoxin (LPS) and interferon-gamma (IFNgamma) in murine aortic endothelial cells (MAEC) was determined. Suppression of PIN1 by 85% with small hairpin RNA enhanced the induction of NO and iNOS protein by LPS-IFNgamma. There was no effect on induction of iNOS mRNA, suggesting a posttranscriptional effect. The enhanced levels of iNOS protein were functionally significant since LPS-IFNgamma was cytotoxic to MAEC lacking PIN1 but not MAEC harboring an inactive control construct, and because cytotoxicity was blocked by the NO synthase inhibitor N(omega)-nitro-L-arginine methyl ester. Consistent with posttranscriptional action, knockdown of PIN1 increased the stability of iNOS protein in cycloheximide-treated cells. Furthermore, loss of iNOS was blocked by the calpain inhibitor carbobenzoxy-valinyl-phenylalaninal but not by the selective proteasome inhibitor epoxomicin. Immunoprecipitation indicated that PIN1 can interact with iNOS. Pull down of iNOS with a wild-type glutathione-S-transferase-PIN1 fusion protein, but not with a mutant of the amino terminal phospho-(serine/threonine)-proline binding WW domain of PIN1, indicated that this domain mediates interaction. The results suggest that PIN1 associates with iNOS and can limit its induction by facilitating calpain-mediated degradation in MAEC.

Abstract
Inducible nitric oxide synthase (iNOS)-derived NO plays an important role in several neurological disorders. Understanding of mechanisms involved in the regulation of iNOS induction is of particular interest. Here, we investigated mechanisms of iNOS induction in rat astrocytes (AC) and in brain endothelial cells (BEC). We find that activation of AC or BEC with pro-inflammatory cytokines reveals a different cell-specific activation pattern for iNOS expression. Despite these differences, in both cell types iNOS expression and activity exclusively depends on the endogenous availability of bioactive IL-1beta as inhibition of ICE activity significantly decreases iNOS promoter activity, iNOS expression and enzyme activity. In summary, we here provide evidence that ICE represents a target for modulating iNOS expression and high-output NO formation in AC and BEC, to our knowledge the first report of a role of ICE in iNOS expression and the advantage of ICE inhibition in attenuating NO mediated inflammation and pathology.
