Pulmonary hypertension (PH) is a progressive disease characterized by elevated blood pressure in the pulmonary arteries, associated also with inflammation and oxidative stress. Inducible nitric oxide synthase (iNOS) one of key mediators immune system activation. Although preclinical studies mostly suggest detrimental role iNOS overactivation PH, there lack exhaustive analyses summaries. Therefore, this literature overview aims to fill gap. The involvement pathogenesis four main clinical groups PH discussed assess whether targeting could be promising way treat PH. expression patterns organs primarily affected are analyzed both animals humans. Consequently, effectiveness pharmacological inhibition and/or gene deletion compared, reference activity constitutive NOS isoforms, particularly endothelial (eNOS). Overall, our suggests that selective inhibitors considered as novel treatment strategy for decreases right ventricular artery pressure, alleviation hypertrophy, improvements cardiac function were observed, among others. Nevertheless, further research efforts area needed.

Nitric oxide (NO) and reactive nitrogen species (RNS) exert profound biological impacts dictated by their chemistry. Understanding spatial distribution is essential for deciphering roles in diverse processes. This review establishes a framework the chemical biology of NO RNS, exploring dynamic reactions within context cancer. Concentration-dependent signaling reveals distinctive processes cancer, with three levels influencing oncogenic properties. In this context, plays crucial role cancer cell proliferation, metastasis, chemotherapy resistance, immune suppression. Increased NOS2 expression correlates poor survival across different tumors, including breast Additionally, can crosstalk proinflammatory enzyme cyclooxygenase-2 (COX-2) to promote progression. COX-2 co-expression positive feed-forward loop, driving immunosuppression metastasis estrogen receptor-negative (ER-) Spatial evaluation orthogonal expression, suggesting unique these niches tumor microenvironment (TME). COX2 niche formation requires IFN-γ cytokine-releasing cells. These contribute clinical outcomes, emphasizing Strategies target markers include direct inhibition, involving pan-inhibitors selective inhibitors, as well indirect approaches targeting induction or downstream effectors. Compounds from cruciferous vegetables are potential candidates inhibition offering therapeutic applications. Thus, understanding distribution, implications progression provides valuable insights developing targeted therapies preventive strategies.

Alzheimer's disease (AD) is the most common neurodegenerative disorder characterized by early molecular events that influence progression. Still, mechanisms caused different mutations of AD are not understood. We have performed a multidisciplinary study to investigate and compare stages pathology in two transgenic mouse models: P301S 5xFAD. Using SNOTRAP-based mass spectrometry, we assessed changes S-nitrosylation, nitric oxide-mediated post-translational modification, proteins both models during their juvenile age. The increased levels 3-nitrotyrosine confirmed nitrosative stress mutant mice. Systems biology analysis revealed shared processes between models, particularly γ-aminobutyric acid (GABA)ergic glutamatergic neurotransmission processes. In model, identified 273 S-nitrosylated (SNOed) cortex, with 244 uniquely SNOed diseased 5xFAD 309 were identified. found altered expression glutamate/GABA-related markers cortex hippocampus models. Additionally, phosphorylation mTOR signaling components hyperactivation this pathway Conversely, mice showed no significant except for elevated ribosomal protein S6 cortex. Our findings key stages. These could serve as potential biomarkers therapeutic targets early-stage AD.

Glioblastoma (GBM) represents the foremost prevalent and aggressive form of primary brain tumor, characterized by high morbidity mortality rates. Nitric oxide (NO) has been shown to have diverse effects on various cancers, including GBM. Our previous study NO synthase (NOS) hyperactivation in GBM cell lines. survival was reversed NOS-targeting pharmacological inhibition vitro. The current work explores impact inducible neuronal NOS (iNOS nNOS) inhibitors, BA-103 BA-101, respectively, a glioblastoma xenograft model. Both agents mitigate nitrosative stress through distinct mechanisms. NOD-SCID mice were used establish subcutaneous tumor model with U-87 MG cells. BA-101 administered via intraperitoneal injections. Tumor metrics, weight volume, assessed. Immunofluorescence Western blots conducted assess stress, proliferation, death. Treatment particularly significantly reduced volume A dose-dependent identified 80 mg/kg as most efficacious dose for treatment. Combining antitumor drug temozolomide (TMZ) synergistically size increased survivability bearing TMZ-sensitive findings suggest that targeting nNOS holds promise therapeutic strategy
