Targeting angiogenesis as a predominant strategy has shown limited effects in many contexts including peripheral arterial disease (PAD). One potential reason for the unsuccessful outcome is the interdependence between inflammation and angiogenesis. Inflammation-based therapies primarily target inflammatory cytokines such as interleukin-6 (IL-6) in T cells, macrophages, cancer cells, muscle cells. However, the mechanism of how these cytokines act on endothelial cells under PAD-specific hypoxia serum starvation (HSS) conditions are not well understood. Thus, we focus on one of the major inflammatory cytokines, IL-6, mediated intracellular signaling in endothelial cells under HSS conditions by conducting relevant in vitro experiments on human umbilical vein endothelial cells (HUVECs) and developing an experimentally validated computational model. Our model quantitatively characterized the effects of IL-6 classic and trans-signaling in activating the signal transducer and activator of transcription 3 (STAT3), phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), and mitogen-activated protein kinase (MAPK) signaling to phosphorylate STAT3, extracellular regulated kinase (ERK) and Akt, respectively in endothelial cells under HSS condition. The trained and validated experiment-based computational model was used to characterize the dynamics of phosphorylated STAT3 (pSTAT3), Akt (pAkt), and ERK (pERK) in response to IL-6 classic and/or trans-signaling under HSS conditions. The model predicts that IL-6 classic and trans-signaling induced responses are dose dependent. In addition, IL-6 trans-signaling induces greater downstream signaling responses compared to classic signaling and plays a dominant role in the overall effects due to a tighter binding of the ligand and receptors and an abundant supply of soluble receptor sIL-6R because of the experimental setting. Moreover, our model identifies the species and kinetic parameters that specifically have a significant impact on the phosphorylation of STAT3, Akt, and ERK, which represent potential targets for the inflammatory cytokine mediated signaling and angiogenesis-based therapies under HSS conditions. Overall, the model predicts the effects of IL-6 classic and/or trans-signaling stimulation under HSS condition quantitatively and provides a framework for analyzing and integrating experimental data. More broadly, this model can be applied to identify potential targets that influence inflammatory cytokine mediated signaling in endothelial cells under HSS conditions and to investigate the effects of angiogenesis- and inflammation-based therapies specific to PAD.</div></div>","PeriodicalId":297,"journal":{"name":"Cytokine","volume":"195 ","pages":"Article 157029"},"PeriodicalIF":3.7,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145045071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The complex molecular immunopathogenesis involves loss of regulatory control of the generation &amp; release of proinflammatory cytokines at both local as well as systemic levels. Excessive secretion of pro-inflammatory cytokines and chemokines leads to the dysregulation of the innate immune system leading to the cytokine storm. Owing to the enormous release of inflammatory factors and active mediators, cytokine storm induces severe damage to secondary tissues, leading to Acute Respiratory Distress Syndrome (ARDS) or multiple-organ failure, which evokes aggravation of the disease and eventually death. Comparisons amid COVID-19 cytokine storm and several other types of cytokine storm associated diseases, gives proper insights about the etiology of cytokine storm in COVID-19. Various genetic and physiological factors contribute to severe disease progression and aggravation of the disease. In that view, several immunoregulatory therapies have been tailored to curb the cytokine storm, which might be crucial in improving the success rates of various treatment strategies as well as in lowering the mortality rate in COVID-19 patients.

A hallmark of IFN-γ responses is inducible nitric oxide (NO), driven primarily by nitric oxide synthase (NOS)2. In this study, we investigated the influence of NO on the IFN-γ-induced transcriptomic and metabolic changes in the RAW 264.7 macrophage cell line. IFN-γ activation led to NO-dependent lactate production and lower cell survival. Bulk RNA sequencing analysis identified genes differentially expressed early by IFN-γ that were either NO-independent or NO-dependent. Inhibition of NO modulated a minor subset of the transcriptome, notably affecting <em>Klf6</em> (a tumor suppressor) and <em>Zfp36</em> (a regulator of pro-inflammatory cytokines). Interestingly, both <em>Klf6</em> and <em>Zfp36</em> correlatively showed high expression in most cancers.

Interestingly, the RNA seq analysis identified IFN-γ upregulated genes, <em>Nampt, Pnp</em> and <em>Pnp2</em>, to be involved in nicotinamide metabolism. This novel aspect was experimentally tested to show that IFN-γ induced NAD⁺ amounts in a NO-dependent manner. Importantly, the inhibition of purine nucleoside phosphorylase (PNP) which is involved in the endogenous pathway for NAD⁺ generation, lowered IFN-γ-induced nitrite and increased cell survival, demonstrating biological relevance of this study. Interestingly, <em>NAMPT</em> and <em>PNP</em> are expressed in multiple organs in humans and Epstein Barr Virus (EBV)-transformed lymphocytes. In addition, polymorphisms in <em>NAMPT</em> and <em>PNP</em> are associated with several diseases.
