objective(s): fluvoxamine is a well-known selective serotonin reuptake inhibitor (ssri); despite its anti-inflammatory effect, little is known about the precise mechanisms involved. in our previous work, we found that ip administration of fluvoxamine produced a noticeable anti-inflammatory effect in carrageenan-induced paw edema in rats. in this study, we aimed to evaluate the effect of fluvoxa...

The purpose of this study was to explore the anti-inflammatory mechanism walnut peptide LPF in LPS-induced RAW264.7 cells model. down-regulated phagocytic ability and production nitric oxide (NO) induced by LPS-stimulated RAW264.7. Molecular docking analysis showed that can bind into active pocket inducible synthase (iNOS) with high affinity. Further, mRNA expression (iNOS), cyclooxygenase-2 (C...

interleukin-1β (il-1β) has a role in β- cell destruction in autoimmune diabetes by stimulating the expression of inducible nitric oxide synthase (inos) that generates the free radical nitric oxide. we aimed to investigate the effect of achillea millefolium l, as a traditional hypoglycemic agent, on il-1β and inos gene expression of pancreatic tissue in the stz- induced diabetic rats. forty adul...

Inducible nitric oxide synthase (iNOS) has been implicated as a mediator in myocardial protection, but this property of iNOS is still conflicting. Therefore, the present study was designed to assess whether iNOS really contributes to the ischemically and pharmacologically induced delayed cellular protection (DCP) in mice myocytes. The following groups of cultured iNOS gene-knockout (iNOS-/-), a...

In rat aorta rings (RA) and in gastric circular muscle (CM) and gastric longitudinal muscle (LM) preparations maintained in vitro, inducible nitric oxide synthase (iNOS) induction was monitored functionally (1 mM L-arginine-induced relaxation), biochemically (appearance of iNOS mRNA), and immunohistochemically. Functional iNOS (L-arginine-mediated relaxation) was induced in RA and CM tissues (b...

Nitric oxide (NO) generated by inducible NO synthase (iNOS) plays crucial roles in inflammation and host defense. With an intrinsically bound calmodulin, iNOS is fully active once expressed in cells. Thus, regulation of NO production from iNOS was thought to primarily occur at the enzyme transcriptional level. Here we show that NO synthesis from iNOS can be profoundly modulated by heat shock pr...

The aim of these experiments was to determine the contribution of leukocyte-derived iNOS to total iNOS expression induced by lipopolysaccharide (LPS). By transferring bone marrow between iNOS+/+ and iNOS-/- mice, we created chimeric mice in which iNOS expression was limited to either circulating leukocytes (leukocyte-iNOS mice) or parenchymal cells (parenchyma-iNOS mice). Analysis of congenic m...

BACKGROUND Estrogen is vasoprotective in animal models of vascular injury, yet the mechanisms involved are incompletely understood. The role of inducible nitric oxide synthase (iNOS) in vascular repair is controversial, but many lines of evidence indicate that it plays a role in neointima formation after arterial injury and that 17beta-estradiol (E(2)) modulates iNOS expression. This study test...

Herbs are essential resources for drug discovery. However, numerous challenges stand in front of the scientific community to discover novel drugs from herbs. To explore validation behind precious knowledge traditional medicine, we focused on achieving virtual screening detect potential medicines Five bioactive compounds known anti-inflammatory medicinal plants were examined through molecular do...

BACKGROUND AND AIMS Overproduction of nitric oxide via inducible nitric oxide synthase (iNOS) is suggested to be a significant pathogenic factor in Helicobacter pylori induced gastritis. The purpose of this study was to examine the role of iNOS in H pylori associated gastric carcinogenesis. METHODS Two types of mice were used in this study: iNOS deficient mice (iNOS-/-) and wild-type litterma...
