Abstract
BACKGROUND Macrophages play a central role in inflammation by phagocytosing invading pathogens, apoptotic cells and debris, as well as mediating repair of tissues damaged by trauma. In order to do this, these dynamic cells generate a variety of inflammatory mediators including eicosanoids such as prostaglandins, leukotrienes and hydroxyeicosatraenoic acids (HETEs) that are formed through the cyclooxygenase, lipoxygenase and cytochrome P450 pathways. The ability to examine the effects of eicosanoid production at the protein level is therefore critical to understanding the mechanisms associated with macrophage activation. RESULTS This study presents a stable isotope labelling with amino acids in cell culture (SILAC) -based proteomics strategy to quantify the changes in macrophage protein abundance following inflammatory stimulation with Kdo2-lipid A and ATP, with a focus on eicosanoid metabolism and regulation. Detailed gene ontology analysis, at the protein level, revealed several key pathways with a decrease in expression in response to macrophage activation, which included a promotion of macrophage polarisation and dynamic changes to energy requirements, transcription and translation. These findings suggest that, whilst there is evidence for the induction of a pro-inflammatory response in the form of prostaglandin secretion, there is also metabolic reprogramming along with a change in cell polarisation towards a reduced pro-inflammatory phenotype. CONCLUSIONS Advanced quantitative proteomics in conjunction with functional pathway network analysis is a useful tool to investigate the molecular pathways involved in inflammation.

Abstract
Inflammation in the tumor microenvironment is a hallmark of cancer and is recognized as a key characteristic of carcinogens. However, the failure of resolution of inflammation in cancer is only recently being understood. Products of arachidonic acid and related fatty acid metabolism called eicosanoids, including prostaglandins, leukotrienes, lipoxins, and epoxyeicosanoids, critically regulate inflammation, as well as its resolution. The resolution of inflammation is now appreciated to be an active biochemical process regulated by endogenous specialized pro-resolving lipid autacoid mediators which combat infections and stimulate tissue repair/regeneration. Environmental and chemical human carcinogens, including aflatoxins, asbestos, nitrosamines, alcohol, and tobacco, induce tumor-promoting inflammation and can disrupt the resolution of inflammation contributing to a devastating global cancer burden. While mechanisms of carcinogenesis have focused on genotoxic activity to induce mutations, nongenotoxic mechanisms such as inflammation and oxidative stress promote genotoxicity, proliferation, and mutations. Moreover, carcinogens initiate oxidative stress to synergize with inflammation and DNA damage to fuel a vicious feedback loop of cell death, tissue damage, and carcinogenesis. In contrast, stimulation of resolution of inflammation may prevent carcinogenesis by clearance of cellular debris via macrophage phagocytosis and inhibition of an eicosanoid/cytokine storm of pro-inflammatory mediators. Controlling the host inflammatory response and its resolution in carcinogen-induced cancers will be critical to reducing carcinogen-induced morbidity and mortality. Here we review the recent evidence that stimulation of resolution of inflammation, including pro-resolution lipid mediators and soluble epoxide hydrolase inhibitors, may be a new chemopreventive approach to prevent carcinogen-induced cancer that should be evaluated in humans.

Abstract
There is an under-recognized role of the aryl hydrocarbon receptor (AhR) in co-ordinating the entry and pathophysiology of the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) that underpins the COVID-19 pandemic. The rise in pro-inflammatory cytokines during the 'cytokine storm' induce indoleamine 2,3-dioxygenase (IDO), leading to an increase in kynurenine that activates the AhR, thereby heightening the initial pro-inflammatory cytokine phase and suppressing the endogenous anti-viral response. Such AhR-driven changes underpin the heightened severity and fatality associated with pre-existent high-risk medical conditions, such as type II diabetes, as well as to how racial discrimination stress contributes to the raised severity/fatality in people from the Black Asian and Minority Ethnic (BAME) communities. The AhR is pivotal in modulating mitochondrial metabolism and co-ordinating specialized, pro-resolving mediators (SPMs), the melatonergic pathways, acetyl-coenzyme A, and the cyclooxygenase (COX) 2-prostaglandin (PG) E2 pathway that underpin 'exhaustion' in the endogenous anti-viral cells, paralleling similar metabolic suppression in cytolytic immune cells that is evident across all cancers. The pro-inflammatory cytokine induced gut permeability/dysbiosis and suppression of pineal melatonin are aspects of the wider pathophysiological underpinnings regulated by the AhR. This has a number of prophylactic and treatment implications for SARS-CoV-2 infection and cancers and future research directions that better investigate the biological underpinnings of social processes and how these may drive health disparities.

Abstract
Epithelial-to-mesenchymal transition (EMT) process is prevalent during the progression of tumors. Nasopharyngeal carcinoma (NPC) is no exception. High-mobility group box 1 (HMGB1) was reported to have the effect of inducing EMT in malignancy. However, the impact of HMGB1-induced EMT in NPC is unclear. Resolvin D1 (RvD1) was reported to regress the progression of inflammation and apoptosis of phagocytes. The effect of RvD1 in the EMT is largely unknown. The current research explored the role of RvD1 on HMGB1-induced EMT in NPC. EMT markers were investigated in 10 NPC and 10 nasopharyngitis (NPG) patients using immunohistochemistry and Western blot. In vitro, expression of EMT markers and HMGB1 in CNE1 and CNE2 cells was assessed with immunohistochemical, Western blot, and confocal microscopy after treatment with recombinant human HMGB1 (rhHMGB1) or HMGB1 gene silencing or RvD1. The invasion and migration of NPC cells were detected by scratch test and transwell assay. Overexpression and gene silencing of lipoxin A4 receptor/formyl peptide receptor 2 (ALX/FPR2) and G protein-coupled receptor 32 (GPR32) in CNE2 cells confirmed the effect of RvD1 using Western blots. N-cadherin, vimentin, and HMGB1 were found up-regulated in NPC samples compared with NPG samples, while ZO-1 and E-cadherin were down-regulated in NPC tissues. RhHMGB1-induced EMT in CNE1 and CNE2 cells in a dose-dependent way. CNE2 cell lines treated with rhHMGB1 possessed greater invasion and migration ability, which was confirmed by gene silencing. RvD1 suppressed HMGB1-induced EMT in NPC cells via ALX/FPR2 and GPR32 receptors. These results showed that EMT was obvious in NPC. HMGB1 played a key role in inducing EMT. RvD1 inhibited HMGB1-induced EMT and might have potential application in the area of NPC treatment. Impact statement Nasopharyngeal carcinoma has a high incidence in China. Discussing the molecular mechanism of nasopharyngeal carcinoma is important because of high recurrent rate and low quality of life after treatment. HMGB1, as an important inflammatory factor, promotes the process in many cancers. But little is known about how HMGB1 affects the progress of nasopharyngeal carcinoma cells. In our research, we assessed the role of HMGB1 on metastasis and invasion of nasopharyngeal carcinoma cells. The result of study indicates HMGB1-induced EMT in nasopharyngeal carcinoma cells. Furthermore, we observed that RvD1, which plays an actively protective role in many diseases, controls the migration and invasion of nasopharyngeal carcinoma cells by inhibiting the HMGB1-induced EMT. RvD1 can be further studied as a protective factor for nasopharyngeal carcinoma.

Abstract
Sepsis is a systemic inflammation accompanied by multi-organ dysfunction due to microbial infection. Prostaglandins and their metabolites have long been studied for their importance in regulating the innate immune response. 15-keto-PGE2 (15k-PGE2) is a prostaglandin E2 (PGE2) metabolite, whose further processing is catalyzed by prostaglandin reductase 2 (PTGR2). We showed disruption of the Ptgr2 gene in mice improves the survival rate under both LPS- and cecum ligation/puncture (CLP)-induced experimental sepsis. Knockdown of PTGR2 showed significant accumulation of intracellular 15k-PGE2 in activated macrophages. Both PTGR2 knockdown and exogenous treatment with 15k-PGE2 resulted in reduced pro-inflammatory cytokines production in LPS-stimulated RAW264.7 cells or bone marrow-derived macrophages (BMDM). The same treatment in RAW264.7 and BMDM also led to increased levels of the anti-oxidative transcription factor, Nuclear factor (erythroid-2) related factor-2 (NRF2), augmented anti-oxidant response element (ARE)-mediated reporter activity and upregulated expression of the corresponding anti-oxidant genes. 15k-PGE2 further demonstrated modification to Kelch-like ECH-associated protein 1 (Keap1), a negative regulator of Nrf2, at cysteine 288 (Cys288) site post-translationally. Finally, 15k-PGE2-treated mice were found to be more resistant to experimental sepsis. Taken together, our study affirms the significance of PTGR2 and 15k-PGE2 in mitigating inflammatory responses and suggests a novel anti-oxidative and anti-inflammatory therapy for sepsis through targeting PTGR2 and administering15k-PGE2.

Novel involvement of miR-522-3p in high-mobility group box 1-induced prostaglandin reductase 1 expression and reduction of phagocytosis. BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR CELL RESEARCH 2017; 1864:625-633.

Abstract
Resolution of inflammation is important for physiological homeostasis. Chronic inflammatory diseases may be caused by abnormal resolution of inflammation. However, what causes a failure of inflammatory resolution is unclear. Here we investigated the involvement of high mobility group box 1 (HMGB1) protein in the control of inflammatory resolution as an 'anti-resolution factor'. We first confirmed the increased expression of HMGB1 and prostaglandin reductase 1 (PTGR1) in inflammatory conditions and HMGB1-mediated regulation of the expression of PTGR1. The inhibition of phagocytosis by HMGB1 was abrogated by PTGR1 silencing. PTGR1 was a direct target of miR522-3p and its expression was regulated by miRNA-522-3p inhibitor or mimic. Finally, miR-522-3p had an important role in the regulation of PTGR1 expression by HMGB1. The data indicates that HMGB1-miR-522-3p-PTGR1 axis may be involved in the abnormal resolution of inflammation and suggests that this mechanism might be a target for modulation of chronic inflammatory disorder.
