Summary: This study investigated the ability of Bifidobacterium species to induce iNOS-dependent NO synthesis in macrophages. The results showed that Bifidobacterium can regulate the expression of iNOS and produce NO by activating MAPK kinases. TLR2 and TLR4 receptors are involved in Bifidobacterium-induced macrophage activation and NO production. The study suggests that Bifidobacterium has a protective mechanism in the intestine, and its efficacy is strain-dependent.

Summary: This study found that a subset of taste bud cells and taste neurons express iNOS proteins after inflammation stimulation, and isolated mouse taste epithelium can release NO in vitro. Furthermore, NO may play an important role in inflammation-associated taste disturbances.

Summary: Nitric oxide (NO) is a small molecule that has a significant impact on various biological activities. It has been linked to cancer-related processes and has the potential to be used as an anti-cancer agent. In this study, NO-releasing materials were developed using modified sodium alginate hydrogel, which showed compatibility with cell growth. The release of NO from the hydrogel exhibited distinct kinetic features.

Summary: This study aimed to investigate the effects of virus component analogues on NO production in chicks and found that poly I:C and R848 significantly increased plasma NO concentrations and induced an increase in iNOS mRNA expression. The study also found that these virus analogues decreased mRNA expressions of endothelial NOS and neural NOS in several organs, suggesting that iNOS might be responsible for the increased plasma NO levels. These findings suggest that viral infections facilitate NO production by inducing iNOS and are associated with corticosterone release in birds.

Summary: The study found that heat-killed lactic acid bacteria have immunomodulatory functions and antioxidant activity, making them suitable for use as probiotics. Heat treatment of strains can prolong the shelf-life of probiotic foods and significantly inhibit the expression of nitric oxide synthase and cyclooxygenase-2.

Summary: The study identified a highly conserved NOS gene (HcNOS) in triangle shell mussels, which showed inducibility in response to LPS challenge and tissue transplantation. Mantle grafting induced a prolonged HcNOS/NO response, indicating potential important roles in tissue transplantation.

Summary: Megakaryocytes are important members of the hematopoietic system, responsible for regulating vascular homeostasis through platelets. The process of megakaryopoiesis generates mature megakaryocytes which release proplatelets into blood vessels. Nitric oxide (NO) plays a modulatory role in hematopoiesis and hemostasis. This review summarizes the effect of NO and its signaling on megakaryopoiesis and thrombopoiesis under physiological and pathophysiological conditions.

Summary: Excessive differentiation of osteoclasts contributes to the disruption of bone homeostasis in inflammatory bone diseases. METTL3 deficiency leads to decreased osteoclast differentiation and increased apoptosis in inflammatory conditions, possibly due to the exacerbation of iNOS/NO-mediated mitochondrial dysfunction by promoting Nos2 mRNA stability in a YTHDF1-dependent manner.

Summary: The study revealed that iNOS and CYP2E1 in rat PMNs contribute to oxidative stress induced by MB+PQ through differential regulatory mechanisms, with iNOS being regulated by inflammatory mediators and CYP2E1 expression triggered via the MEK-ERK1/2-PKC pathway.

Summary: Kidney transplantation is the preferred treatment for patients with kidney failure. However, ischemia-reperfusion injury (IRI) poses a significant challenge to the long-term success of this intervention. Nitric oxide (NO) has emerged as a potential candidate for mitigating IRI and preventing graft rejection in kidney transplantation. This review provides an overview of the sources and protective effects of endogenous and exogenous NO in kidney transplantation.

Summary: This paper describes the design, synthesis, and biological evaluation of selective inhibitors of inducible nitric oxide synthase (iNOS). The most potent and selective compound showed inhibitory activity against iNOS without undesirable cardiovascular effects. In silico analysis predicted good drug-likeness properties for promising compounds, which also exhibited adequate cell viability. Docking studies revealed a unique binding mode for one compound and explained its selectivity towards iNOS.
