Mechanisms of mesothelial cell response to viral infections: HDAC1-3 inhibition blocks poly(I:C)-induced type I interferon response and modulates the mesenchymal/inflammatory phenotype. Front Cell Infect Microbiol 2024; 14:1308362. [PMID: 38476167 PMCID: PMC10927979 DOI: 10.3389/fcimb.2024.1308362] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 01/24/2024] [Indexed: 03/14/2024] Open
Abstract
Infectious peritonitis is a leading cause of peritoneal functional impairment and a primary factor for therapy discontinuation in peritoneal dialysis (PD) patients. Although bacterial infections are a common cause of peritonitis episodes, emerging evidence suggests a role for viral pathogens. Toll-like receptors (TLRs) specifically recognize conserved pathogen-associated molecular patterns (PAMPs) from bacteria, viruses, and fungi, thereby orchestrating the ensuing inflammatory/immune responses. Among TLRs, TLR3 recognizes viral dsRNA and triggers antiviral response cascades upon activation. Epigenetic regulation, mediated by histone deacetylase (HDAC), has been demonstrated to control several cellular functions in response to various extracellular stimuli. Employing epigenetic target modulators, such as epidrugs, is a current therapeutic option in several cancers and holds promise in treating viral diseases. This study aims to elucidate the impact of TLR3 stimulation on the plasticity of human mesothelial cells (MCs) in PD patients and to investigate the effects of HDAC1-3 inhibition. Treatment of MCs from PD patients with the TLR3 agonist polyinosinic:polycytidylic acid (Poly(I:C)), led to the acquisition of a bona fide mesothelial-to-mesenchymal transition (MMT) characterized by the upregulation of mesenchymal genes and loss of epithelial-like features. Moreover, Poly(I:C) modulated the expression of several inflammatory cytokines and chemokines. A quantitative proteomic analysis of MCs treated with MS-275, an HDAC1-3 inhibitor, unveiled altered expression of several proteins, including inflammatory cytokines/chemokines and interferon-stimulated genes (ISGs). Treatment with MS-275 facilitated MMT reversal and inhibited the interferon signature, which was associated with reduced STAT1 phosphorylation. However, the modulation of inflammatory cytokine/chemokine production was not univocal, as IL-6 and CXCL8 were augmented while TNF-α and CXCL10 were decreased. Collectively, our findings underline the significance of viral infections in acquiring a mesenchymal-like phenotype by MCs and the potential consequences of virus-associated peritonitis episodes for PD patients. The observed promotion of MMT reversal and interferon response inhibition by an HDAC1-3 inhibitor, albeit without a general impact on inflammatory cytokine production, has translational implications deserving further analysis.

Abstract
Chronic kidney disease (CKD) incidence is growing worldwide, with a significant percentage of CKD patients reaching end-stage renal disease (ESRD) and requiring kidney replacement therapies (KRT). Peritoneal dialysis (PD) is a convenient KRT presenting benefices as home therapy. In PD patients, the peritoneum is chronically exposed to PD fluids containing supraphysiologic concentrations of glucose or other osmotic agents, leading to the activation of cellular and molecular processes of damage, including inflammation and fibrosis. Importantly, peritonitis episodes enhance peritoneum inflammation status and accelerate peritoneal injury. Here, we review the role of immune cells in the damage of the peritoneal membrane (PM) by repeated exposure to PD fluids during KRT as well as by bacterial or viral infections. We also discuss the anti-inflammatory properties of current clinical treatments of CKD patients in KRT and their potential effect on preserving PM integrity. Finally, given the current importance of coronavirus disease 2019 (COVID-19) disease, we also analyze here the implications of this disease in CKD and KRT.

Abstract
BACKGROUND The effects of matrix metalloproteases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) expressions on the patients with constrictive pericarditis undergoing pericardiectomy remain unclear. This study explored the associations of MMPs and TIMPs expressions with postoperative outcomes in these patients. METHODS Pericardial specimens were obtained during pericardiectomy from the patients with constrictive pericarditis. The levels of MMP1, MMP2, MMP9 and TIMP1 in pericardium were analyzed by quantitative real-time polymerase chain reaction. The enrolled patients were divided into two groups according to the optimal cutoff value of gene expression predicting postoperative complications. Postoperative outcomes were compared between the two groups. Binary logistic regression analysis was performed to determine the degree of contribution of gene expression on postoperative outcomes. RESULTS A total of 22 patients and their pericardial specimens were included. The level of MMP9 was significantly associated with postoperative complications and the optimal cutoff value predicting postoperative complications was 3.67. The patients with low level of MMP9 (< 3.67) had lower incidence of postoperative complications (P = 0.002), shorter postoperative intensive care unit (P = 0.040) and hospital stay (P = 0.043) in comparison to those with high level of MMP9 (≥ 3.67). Binary logistic regression analysis showed that high level of MMP9 increased the risk of postoperative complications (OR 27.096, 95% CI 1.166-629.886, P = 0.040). CONCLUSIONS High level of MMP9 in the pericardium was associated with poor postoperative outcomes and was the independent risk factor of postoperative complications. The level of MMP9 could be used as a potential marker for prediction of surgical outcomes.

Abstract
We investigated an in vitro model for mesothelial clearance, wherein ovarian cancer cells invade into a layer of mesothelial cells, resulting in mesothelial retraction combined with cancer cell disaggregation and spreading. Prior to the addition of tumor cells, the mesothelial cells had an elongated morphology, causing them to align with their neighbors into well-ordered domains. Flaws in this alignment, which occur at topological defects, have been associated with altered cell density, motion, and forces. Here, we identified topological defects in the mesothelial layer and showed how they affected local cell density by producing a net flow of cells inward or outward, depending on the defect type. At locations of net inward flow, mesothelial clearance was impeded. Hence, the collective behavior of the mesothelial cells, as governed by the topological defects, affected tumor cell clearance and spreading. Importantly, our findings were consistent across multiple ovarian cancer cell types, suggesting a new physical mechanism that could impact ovarian cancer metastasis.

Abstract
Peritoneal fibrosis is characterized by abnormal production of extracellular matrix proteins leading to progressive thickening of the submesothelial compact zone of the peritoneal membrane. This process may be caused by a number of insults including pathological conditions linked to clinical practice, such as peritoneal dialysis, abdominal surgery, hemoperitoneum, and infectious peritonitis. All these events may cause acute/chronic inflammation and injury to the peritoneal membrane, which undergoes progressive fibrosis, angiogenesis, and vasculopathy. Among the cellular processes implicated in these peritoneal alterations is the generation of myofibroblasts from mesothelial cells and other cellular sources that are central in the induction of fibrosis and in the subsequent functional deterioration of the peritoneal membrane. Myofibroblast generation and activity is actually integrated in a complex network of extracellular signals generated by the various cellular types, including leukocytes, stably residing or recirculating along the peritoneal membrane. Here, the main extracellular factors and the cellular players are described with emphasis on the cross-talk between immune system and cells of the peritoneal stroma. The understanding of cellular and molecular mechanisms underlying fibrosis of the peritoneal membrane has both a basic and a translational relevance, since it may be useful for setup of therapies aimed at counteracting the deterioration as well as restoring the homeostasis of the peritoneal membrane.

Abstract
Bovine mammary fibrosis represents a considerable health problem of cows, primarily indicated by lactation failure. Staphylococcus aureus (S. aureus) can cause mammary damage, this multifactorial disease necessitates to identify how and to what extent molecular pathogen defense mechanisms prevent bacterial infections in bovine mammary gland. In this study, we have aimed to determine the transcriptional responses in bovine mammary fibroblasts (BMFBs) induced by S. aureus using bioinformatics analysis to determine whether mRNA expression profile changes between BMFBs activation and quiescence. Established primary BMFBs obtained from healthy Holstein bovine were induced 106 CFU/mL heat-inactivated S. aureus and total RNA was isolated 6 h after treatment. The 574 DEGs were involved in gene ontology (GO) that were immune response, apoptotic process, extracellular region, receptor binding, endopeptidase activity and protein kinase activity et al. The Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses, distinct pathway contained signaling molecules common to various inflammatory and fibrotic pathways were Pathways in cancer, Cytokine-cytokine receptor interaction, PI3K-Akt signaling pathway, TNF signaling pathway, MAPK signaling pathway and Toll-like receptor signaling pathway. The BMFBs was treated with heat-inactivated S. aureus (106 CFU/mL) and also with pharmacological inhibitors of ERK1/2, P38 MAPK and JNK. The MMP-2 activity were examined gelatin zymography, MMP-2, TIMP-1, -2 and PLAU/PAI-1 protein expression were examined in vitro by western blot. The MMP-2 activity was significantly inhibited by simultaneous inhibition of ERK1/2, P38 MAPK and JNK, and MMP-2, TIMP-1,-2 and PLAU/PAI-1 protein expression were significantly decreased by inhibiting ERK1/2, P38 MAPK or JNK. This suggested a crosstalk between the ERK1/2, P38 MAPK or JNK signaling pathways in regulating extracellular matrix metabolism in the BMFBs with S. aureus. Our study complement our initial study on S. aureus-induced responses by fibrosis-associated genes in BMFBs. This may lead to development of novel therapeutic targets to control bovine mammary fibrosis induced by S. aureus.

Abstract
Toll-like receptor 3 (TLR3) is involved in the virus-induced pulmonary inflammatory response, but its role in airway remodeling after viral infection is unclear. We explored the role of TLR3 in poly(I:C)-induced inflammatory cytokines and mucin 5AC (MUC5AC) production in human bronchial epithelial cells by Western blotting, RT-PCR and ELISA. The expression of TLR3, MUC5AC, Matrixmetalloproteinase (MMP9), Transforming growth factor (TGF-β1) and Vascular endothelial growth factor (VEGF) in human bronchial epithelial cells increased in a dose-dependent manner after exposure to poly(I:C), and this effect was inhibited by treatment with TLR3 siRNA. The phosphorylation of epithelial growth factor receptor (EGFR)/ERK/P38 Mitogen-activated protein kinases (MAPK) proteins increased after poly(I:C) treatment, and inhibition of this signaling pathway decreased TLR3 expression and MUC5AC and TGF-β1 production in human bronchial epithelial cells. The TLR3-EGFR signaling pathway is involved in the production of airway remodeling cytokines after virus infection. Inhibiting EGFR and its signaling pathway may be a therapeutic strategy for modifying airway remodeling.

Abstract
Matrix metalloproteinase-9 (MMP-9) plays a vital role in tumor angiogenesis, cell migration, and invasiveness because it can degrade almost all basement membrane and extracellular matrix components. MMP-9 has been reported in many cancers including breast cancer, lung cancer, and colon cancer. ΔFosB in mammary epithelial cells has been shown to regulate cell proliferation, differentiation, and death. We found that ΔFosB increased the expression of MMP-9 in MCF-7 breast cancer cells. ΔFosB overexpression in MCF-7 cells increased cellular viability and decreased cell apoptosis. SB-3CT, an inhibitor of MMP-9, promoted apoptosis, inhibited cell proliferation, induced cell cycle arrest, and downregulated the expression of antiapoptotic genes Bcl-2 and Bcl-xl in MCF-7 cells. ΔFosB increased the number of MCF-7 cells in G2/M and S phases, upregulated the expression of Bcl-2 and Bcl-xl, and protected MCF-7 cells from apoptosis induced by MMP-9 inhibition. We also found that ΔFosB overexpression in MCF-7 cells inhibited Ca(2+)-induced apoptosis and promoted cell proliferation. Therefore, ΔFosB may be a potential target in breast cancer cell apoptosis by regulating the expression of MMP-9.

Migration-stimulating factor (MSF) is over-expressed in non-small cell lung cancer and promotes cell migration and invasion in A549 cells over-expressing MSF. Exp Cell Res 2013; 319:2545-53.

Abstract
Migration-stimulating factor (MSF), an oncofetal truncated isoform of fibronectin, is a potent stimulator of cell invasion. However, its distribution and motogenic role in non-small cell lung cancer (NSCLC) have never been identified. In this study, real-time PCR and immunohistochemical staining (IHC) were performed to detect MSF mRNA and protein levels in tumor tissues and matched adjacent tumor-free tissues. Furthermore, to examine the effect of MSF on invasiveness, MSF was upregulated in A549 cells. The invasiveness and viability of A549 cells were then determined using a transwell migration assay and the 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) viability assays, respectively. The expression level of MSF in NSCLC tissue was markedly higher than in matched adjacent tumor-free tissue. Additionally, the level of MSF protein expression in stage III and IV NSCLC samples was higher than in stage I and II NSCLC samples. More importantly, we also demonstrated that migration and invasion of A549 cells increased substantially after upregulating MSF, although proliferation remained unchanged. Meanwhile, we found no correlation between increasing motility and invasiveness of MSF-overexpressing cells and expression levels and activities of matrix metalloprotease MMP-2 and MMP-9. Our current study shows that MSF plays a role in migration and invasion of A549 cells and suggests that MSF may be a potential biomarker of NSCLC progression.

Abstract
Background Lung cancer is one of the most lethal malignancies worldwide, but useful biomarkers of lung cancer are still insufficient. The aim of this study is to identify some membrane-bound protein(s) associated with migration and invasion in human non-small cell lung cancer (NSCLC) cells. Methods We classified four NSCLC cell lines into high and low migration/invasion groups by Transwell and Matrigel assays. Using two-dimensional gel electrophoresis and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), we identified 10 membrane-associated proteins being significantly overexpressed in the high migration/invasion group. The expression of the target protein in the four NSCLC cell lines was then confirmed by reverse transcription polymerase chain reaction (RT-PCR), western blot and immunostaining. RNA interference technique was applied to observe the influence of the target protein on migration and invasion. Gelatin zymography was also performed to evaluate the activities of matrix metalloproteinase (MMP)-2 and MMP-9. Expression condition of the target protein on surgical specimens was further examined by immunohistochemical staining and the clinicopathologic data were analyzed. Results We identified a mitochondria-bound protein cytochrome c oxidase subunit Va (COX Va) because of its abundant presence found exclusively in tumorous areas. We also demonstrated that migration and invasion of NSCLC cells decreased substantially after knocking down COX Va by siRNA. Meanwhile, we found a positive correlation between COX Va expression, Bcl-2 expression and activities of MMP-2 and MMP-9 in NSCLC cells. Immunohistochemical staining of surgically resected lung adenocarcinomas in 250 consecutive patients revealed that strong COX Va expression was found in 54.8% (137/250) of patients and correlated positively with the status of lymph node metastasis (P = 0.032). Furthermore, strong COX Va expression was associated with the presence of distant metastasis (P = 0.033). Conclusions Our current study showed that COX Va may play a role in migration and invasion of NSCLC cells and can be used as a biomarker to predict aggressiveness of NSCLC.

Abstract
Genetic evidence indicates that the major gelatinases MMP-2 and MMP-9 are involved in mammalian craniofacial development. Since these matrix metalloproteinases are secreted as proenzymes that require activation, their tissue distribution does not necessarily reflect the sites of enzymatic activity. Information regarding the spatial and temporal expression of gelatinolytic activity in the head of the mammalian embryo is sparse. Sensitive in situ zymography with dye-quenched gelatin (DQ-gelatin) has been introduced recently; gelatinolytic activity results in a local increase in fluorescence. Using frontal sections of wild-type mouse embryo heads from embryonic day 14.5-15.5, we optimized and validated a simple double-labeling in situ technique for combining DQ-gelatin zymography with immunofluorescence staining. MMP inhibitors were tested to confirm the specificity of the reaction in situ, and results were compared to standard SDS-gel zymography of tissue extracts. Double-labeling was used to show the spatial relationship in situ between gelatinolytic activity and immunostaining for gelatinases MMP-2 and MMP-9, collagenase 3 (MMP-13) and MT1-MMP (MMP-14), a major activator of pro-gelatinases. Strong gelatinolytic activity, which partially overlapped with MMP proteins, was confirmed for Meckel's cartilage and developing mandibular bone. In addition, we combined in situ zymography with immunostaining for extracellular matrix proteins that are potential gelatinase substrates. Interestingly, gelatinolytic activity colocalized precisely with laminin-positive basement membranes at specific sites around growing epithelia in the developing mouse head, such as the ducts of salivary glands or the epithelial fold between tongue and lower jaw region. Thus, this sensitive method allows to associate, with high spatial resolution, gelatinolytic activity with epithelial morphogenesis in the embryo.

Abstract
Interferon-inducible protein 10 (IP-10) is a chemokine playing an important role in the restriction of viral spread. A time- and dose-dependent increase in IP-10 is found upon activation of viral receptors expressed on mesothelial cells, which provides novel evidence for a link between viral infections and inflammation of serous membranes.
