ENVIRONMENTAL TOXICOLOGY 2024; 39:3967-3979. [PMID: 38598732 DOI: 10.1002/tox.24256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 02/01/2024] [Accepted: 03/14/2024] [Indexed: 04/12/2024]
Abstract
Mono-(2-ethylhexyl) phthalate (MEHP) can accumulate in the liver and then lead to hepatic steatosis, while the underlying mechanism remains unclear. Inflammation plays an important role in the disorder of hepatic lipid metabolism. This study aims to clarify the role of the inflammatory response mediated by formyl peptide receptor 2 (FPR2) in steatosis of L02 cells exposed to MEHP. L02 cells were exposed to MEHP of different concentrations and different time. A steatosis model of L02 cells was induced with oleic acid and the cells were exposed to MEHP simultaneously. In addition, L02 cells were incubated with FPR2 antagonist and then exposed to MEHP. Lipid accumulation was determined by oil red O staining and extraction assay. The indicators related to lipid metabolism and inflammatory response were measured with appropriate kits. The relative expression levels of FPR2 and its ligand were determined by Western blot, and the interaction of them was detected by co-immunoprecipitation. As a result, MEHP exposure could promote the occurrence and progression of steatosis and the secretion of chemokines and inflammatory factors in L02 cells. MEHP could also affect the expression and activation of FPR2 and the secretion of FPR2 ligands. In addition, the promotion effect of MEHP on the secretion of total cholesterol and interleukin 1β in L02 cells could be significantly inhibited by the FPR2 antagonist. We concluded that FPR2 might affect the promotion effect of MEHP on steatosis of L02 cells by mediating inflammatory response.

Abstract
Venous thromboembolism (VTE) remains a major health burden despite anticoagulation advances, suggesting incomplete management of pathogenic mechanisms. The NLRP3 (NACHT-, LRR- and pyrin domain-containing protein 3) inflammasome, interleukin (IL)-1, and pyroptosis are emerging contributors to the inflammatory pathogenesis of VTE. Inflammasome pathway activation occurs in patients with VTE. In preclinical models, inflammasome signaling blockade reduces venous thrombogenesis and vascular injury, suggesting that this therapeutic approach may potentially maximize anticoagulation benefits, protecting from VTE occurrence, recurrence, and ensuing post-thrombotic syndrome. The nonselective NLRP3 inhibitor colchicine and the anti-IL-1β agent canakinumab reduce atherothrombosis without increasing bleeding. Rosuvastatin reduces primary venous thrombotic events at least in part through lipid-lowering independent mechanisms, paving the way to targeted anti-inflammatory strategies in VTE. This review outlines recent preclinical and clinical evidence supporting a role for inflammasome pathway activation in venous thrombosis, and discusses the, yet unexplored, therapeutic potential of modulating inflammasome signaling to prevent and manage VTE.

Ann Vasc Surg 2023; 89:280-292. [PMID: 36441086 DOI: 10.1016/j.avsg.2022.09.056] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Revised: 08/24/2022] [Accepted: 09/19/2022] [Indexed: 01/25/2023]
Abstract
BACKGROUND The role of inflammation in venous thromboembolism (VTE) has been the focus of recent research. The NLRP3/IL-1/NF-κB signaling pathway and cytokines such as IL-1, regulated by macrophage polarization, may be the key indicators of a prethrombotic state; however, the mechanisms by which they affect the occurrence of VTE remain unclear. METHODS We used neurobiological clamps to stimulate the vein wall to induce vascular endothelial damage to generate a rat model of VTE, applied enzyme-linked immunosorbent assay and real time-polymerase chain reaction technology to identify key proteins (IL1β, Caspase-1, NLRP3, and NF-κB P65), gene mRNA levels and protein expression levels of the NLRP3/IL-1/NF-κB signaling pathway in each group of Sprague Dawley rats, and observed the polarization state of M1 (CD86) and M2 (CD206) macrophages using immunohistochemistry. RESULTS A dark red, small thrombus developed in the inferior vena cava immediately after modeling in the model and inhibitor groups. The plasma levels of IL-1 and TNF-α, mRNA expression of key proteins (IL1β, Caspase-1, NLRP3, and NF-κB P65), and expression of key proteins (IL1β, Caspase-1, NLRP3, and NF-κB P65) in VTE model rats were significantly higher than inhibitor, sham operation, and normal control groups (P < 0.05). Six hours after VTE modeling, M1 type macrophages were more significantly increased than M2 type macrophages in thrombus tissue (P < 0.05). CONCLUSIONS Our analyses demonstrated that the nod-like receptor protein3/Interleukin-1/nuclear factor-κB signaling pathway and macrophage polarization are important in the occurrence and development of VTE and that their target regulation may become a new strategy for VTE prevention and treatment.

Front Neurol 2022; 13:829090. [PMID: 35370905 PMCID: PMC8967952 DOI: 10.3389/fneur.2022.829090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2021] [Accepted: 02/15/2022] [Indexed: 11/30/2022] Open
Abstract
Aim This study aimed to explore the effect of enriched rehabilitation (ER) on cognitive function and serum glutamate levels in patients with stroke. Methods Forty patients diagnosed with post-stroke cognitive impairment (PSCI), according to the inclusion criteria, and undergoing inpatient rehabilitation were enrolled in the study. Patients were randomly assigned to receive 8 weeks of ER treatment (ER group; n = 20) or conventional medical treatment (CM group; n = 20). In addition, 20 age-matched healthy subjects who were outpatients in our hospital during the same period formed the healthy control (HC) group. In- and between-group differences in cognitive function were assessed during pre-intervention and post-intervention based on the Montreal Cognitive Assessment (MoCA), the Symbol Digit Modalities Test (SDMT), and the Trail Making Test (TMT). The serum levels of glutamate, tumor necrosis factor (TNF), and malondialdehyde (MDA) levels were also detected pre-intervention and post-intervention. Results Pre-intervention cognitive function and the levels of all the serum parameters assessed significant difference between the HC group and the PSCI group (both ER and CM groups) (p < 0.05), but not between the two groups of patients with PSCI (p > 0.05). Significant improvements were observed in cognitive function in both the ER and the CM groups post-intervention compared with pre-intervention, as evidenced by the measured improvement in MoCA, SDMT, and TMT scores. Similar improvements were seen for serum glutamate, the degree of oxidative damage, and the level of inflammation in both the treatment groups (p < 0.05). More enhancements in cognitive function, including MoCA, SDMT, TMT scores, and the serum levels of glutamate, the degree of oxidative damage, and the level of inflammation were shown in the ER group compared with the CM group post-intervention (p < 0.05). Conclusions ER can improve cognitive function in patients with PSCI. The associated mechanism may be related to the negative regulatory effect of ER on serum glutamate, TNF, and MDA levels, which is likely to enhance synaptic plasticity and alleviate oxidative stress- and inflammation-related damage, at least to some extent.

Biomarker signatures in cancer patients with and without venous thromboembolism events: a substudy of CASSINI. Blood Adv 2022; 6:1212-1221.

Abstract
Cancer is associated with an increased risk of venous thromboembolism (VTE). In the CASSINI study, ambulatory cancer patients with a Khorana risk score ≥2 had a reduced risk of VTE while receiving rivaroxaban. This analysis used blood samples from CASSINI to compare biomarker levels between patients with and without VTE. VTE occurred in 62 patients during the 6 months of CASSINI (cases), and they were matched by age, sex, cancer type, tumor stage, and Khorana score to 62 controls. Baseline blood samples were analyzed for 280 biomarkers, and biomarker distribution was compared using the Wilcoxon rank-sum test between groups defined by VTE occurrence and vital status. Sparse Bayesian regression modeling was used to select a joint panel of potential VTE biomarkers. Biomarkers with the largest differences in baseline distribution among cancer patients with and without VTE included decreases in stromal cell-derived factor-1 (SDF-1), thyroid-stimulating hormone (TSH), and monocyte chemotactic protein 4 and increases in growth hormone (GH) and interleukin-1 receptor type 1 (IL-1R1). Between survivors and those who died, significantly different biomarkers included ST2, IL-8, and C-reactive protein. Regression analyses also identified decreases in SDF-1 and TSH. Pathway analysis indicated enrichment of cytokine and chemokine activity with IL-1R1, SDF-1, and GH, which are the strongest predictors of VTE or death. Our analyses highlight the interactions between hemostatic and inflammatory processes and identify candidate biomarkers of cancer-associated VTE. Prospective studies will determine clinical relevance of these biomarkers. This trial was registered at www.ClinicalTrials.gov as #NCT02555878.

Abstract
Background Venous thromboembolism (VTE) is the third most common cause of cardiovascular death worldwide, following coronary heart disease and stroke, and many risk factors for VTE are not yet clear. Our study investigated the association between multiple inflammatory gene polymorphisms and VTE prognosis, aiming to find a new predictor of VTE prognosis. Methods Based on our previous studies, we detected the plasma levels of serum amyloid A protein (SAA), interleukin-1 (IL-1) and tumor necrosis factor-a (TNF-a) and their 8 gene polymorphisms by ELISA and a multiplex ligation detection reaction (iMLDR) method in 284 patients with VTE. All subjects were followed up for 5 years. Results The 5-year follow-up results of this study showed that 62 of the 284 patients (21.83%) had reached the endpoint (all-cause death). Kaplan–Meier survival analyses revealed that the mortality rate of VTE patients with a high Simplified Pulmonary Embolism Severity Index (SPESI) score and carrying IL-1 rs1800587 mutation genotypes was significantly increased (log-rank p=0.000 and 0.034 respectively). The multifactor Cox regression results confirmed that the mortality rate of patients who carrying IL-1 rs1800587 mutation genotypes was significantly increased (HR=2.982; 95% CI: 1.681–5.100). The mortality rate of those carrying IL-1 rs1143634 mutation genotypes was significantly decreased (HR=0.294; 95% CI: 0.132–0.652). There were no significant differences in mortality rates between wild-type and mutant genotypes of IL-1 rs1143634, IL-1 rs2234650, SAA rs11603089, and TNF-α rs1800629 (P>0.05). Conclusion A high SPESI score and the presence of the IL-1 rs1800587 mutant genotype predict shorter survival in patients with VTE, whereas the IL-1 rs1143634 genotype is associated with a lower mortality rate. Screening for mutations in inflammation-related genes has prognostic value in the clinical management of VTE.

Abstract
Background The onset of venous thromboembolism is insidious and the prognosis is poor. In this study, we aimed to construct a VTE risk warning model and testified its clinical application value. Methods Preliminary construction of the VTE risk warning model was carried out according to the independent risk warning indicators of VTE screened by Logistic regression analysis. The truncated value of screening VTE was obtained and the model was evaluated. ROC curve analysis was used to compare the test of Caprini risk assessment scale and VTE risk warning model. The cut-off value of the VTE risk warning model was used to evaluate the test effectiveness of the model for VTE patients with validation data set. Results The VTE risk warning model is p = ex / (1+ ex), x = − 4.840 + 2.557 • X10(1) + 1.432 • X14(1) + 2.977 • X15(1) + 3.445 • X18(1) + 1.086 • X25(1) + 0.249 • X34 + 0.282 • X41. ROC curve results show that: AUC (95%CI), cutoff value, sensitivity, specificity, accuracy, Youden index, Caprini risk assessment scale is 0.596 (0.552, 0.638), 5, 26.07, 96.50, 61.3%, 0.226, VTE risk warning model is 0.960 (0.940, 0.976), 0.438, 92.61, 91.83, 92.2%, 0.844, respectively, with statistically significant differences (Z = 14.521, P < 0.0001). The accuracy and Youden index of VTE screening using VTE risk warning model were 81.8 and 62.5%, respectively. Conclusions VTE risk warning model had high accuracy in predicting VTE occurrence in hospitalized patients. Its test performance was better than Caprini risk assessment scale. It also had high test performance in external population.
