Expression of C-C motif chemokines and their receptors in bovine placentomes at spontaneous and induced parturition. J Reprod Dev 2020; 66:49-55. [PMID: 31761882 PMCID: PMC7040214 DOI: 10.1262/jrd.2019-113] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Accepted: 11/03/2019] [Indexed: 01/01/2023] Open
Abstract
In bovine placentomes, the inflammatory response is considered important for the detachment of the fetal membrane from the caruncle after parturition. Glucocorticoids, a trigger of the onset of parturition, facilitate functional maturation of placentomes via prostaglandin (PG) and estrogen production in cattle. This study investigated how exogeneous glucocorticoids, which exert immunosuppressive effects, affect placental inflammation at parturition. Placentomes were collected immediately after spontaneous or induced parturition. Parturition was conventionally induced using PGF2α or dexamethasone or with a combination of triamcinolone acetonide and high-dose betamethasone (TABET treatment). Polymerase chain reaction (PCR) array analysis indicated that 9/13 C-C motif chemokine ligands (CCLs) were upregulated > two-fold in spontaneous parturition, with CCL2 and CCL8 being highly expressed. The expressions of CCL2, CCL8, C-C motif chemokine receptor 1 (CCR1), and CCR5 in caruncles were significantly higher in spontaneous parturition than in induced parturition. Although the clinical dose of dexamethasone did not influence the expression of these CCLs and CCRs, TABET treatment increased CCR1 expression. CCL8, CCR1, CCR2, and CCR5 were localized in the caruncular epithelial cells. CCR2 was also localized in the epithelial cells of the cotyledonary villi. This study is the first report to reveal the disruption in CCL and CCR expression in bovine placentomes at induced parturition. Enhanced glucocorticoid exposure for the induction of parturition may upregulate CCR1 expression in placentomes, but the treatment does not adequately promote CCL expression. Additionally, immunohistochemistry suggested that the CCL-CCR system is involved in the functional regulation of maternal and fetal epithelial cells in placentomes at parturition.

Neutrophil Adaptations upon Recruitment to the Lung: New Concepts and Implications for Homeostasis and Disease. Int J Mol Sci 2020; 21:ijms21030851. [PMID: 32013006 PMCID: PMC7038180 DOI: 10.3390/ijms21030851] [Citation(s) in RCA: 51] [Impact Index Per Article: 12.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Revised: 01/24/2020] [Accepted: 01/27/2020] [Indexed: 12/14/2022] Open
Abstract
Neutrophils have a prominent role in all human immune responses against any type of pathogen or stimulus. The lungs are a major neutrophil reservoir and neutrophilic inflammation is a primary response to both infectious and non-infectious challenges. While neutrophils are well known for their essential role in clearance of bacteria, they are also equipped with specific mechanisms to counter viruses and fungi. When these defense mechanisms become aberrantly activated in the absence of infection, this commonly results in debilitating chronic lung inflammation. Clearance of bacteria by phagocytosis is the hallmark role of neutrophils and has been studied extensively. New studies on neutrophil biology have revealed that this leukocyte subset is highly adaptable and fulfills diverse roles. Of special interest is how these adaptations can impact the outcome of an immune response in the lungs due to their potent capacity for clearing infection and causing damage to host tissue. The adaptability of neutrophils and their propensity to influence the outcome of immune responses implicates them as a much-needed target of future immunomodulatory therapies. This review highlights the recent advances elucidating the mechanisms of neutrophilic inflammation, with a focus on the lung environment due to the immense and growing public health burden of chronic lung diseases such as cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD), and acute lung inflammatory diseases such as transfusion-related acute lung injury (TRALI).

Abstract
INTRODUCTION Diabetes mellitus (DM) patients suffer from high morbidity and premature mortality due to various diabetic complications and even cancers. Therefore, this study aimed to identify key genes involved in the pathogenesis of diabetic peripheral neuropathy (DPN) and pancreatic cancer (PC). METHODS We analyzed three gene expression profiles (GSE95849, GSE28735 and GSE59953) to obtain differentially expressed genes (DEGs). Then, Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed by using the Database for Annotation, Visualization, and Integrated Discovery (DAVID). The Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database was then used to establish a protein-protein interaction (PPI) network. The MCODE and cytoHubba plug-ins of Cytoscape were used to select hub genes. Finally, survival analysis of the hub genes was performed using the Kaplan-Meier plotter and GEPIA online tool. RESULTS We first analyzed GSE95849 to obtain DPN-related genes. DEGs were obtained from three groups in GSE95849. The DEGs were enriched in the Toll-like receptor signaling pathway, hematopoietic cell lineage and chemokine signaling pathway. Importantly, we identified three shared genes as hub genes, including TLR4, CCR2 and MMP9. We then analyzed and integrated GSE95849 and GSE28735 to obtain genes common in DM and PC. A total of 58 mutual DEGs were identified, and these DEGs were enriched in the ECM-receptor interaction, focal adhesion and pathways in cancer. Five hub genes (including PLAU, MET, CLU, APOL1 and MMP9) were associated with the overall survival of PC patients. However, the results from the analysis of GSE59953 showed that hyperglycemia or TGF-β1 treatment did not affect the expression level of these hub genes, but the DEGs based on hyperglycemia or TGF-β1 treatment were mostly enriched in the ECM-receptor interaction, focal adhesion and pathways in cancer. Finally, functional enrichment analysis of MMP9 showed that significant genes correlated with MMP9 were associated with the tumorigenicity of cancers, insulin resistance, development of DM and inflammation. CONCLUSION In summary, inflammation and immunity-related pathways may play an important role in DM and DPN, while the ECM-receptor interaction, focal adhesion and pathways in cancer pathways may play significant roles in DM and PC. MMP9 may be used as a prognostic marker for PC and may be helpful for the treatment of DM, DPN and PC.

Abstract
OBJECTIVES To evaluate the diagnostic value of matrix metalloproteinase-9 (MMP-9), tissue inhibitor of metalloproteinase-1 (TIMP-1), and the MMP-9/TIMP-1 ratio in fetal inflammatory response syndrome (FIRS), and determine a possible association with the incidence of bronchopulmonary dysplasia (BPD) and myocardial injury. METHODS Overall, 61 cases of preterm infants with FIRS were divided into the FIRS group 1 (≤32 weeks) and FIRS group 2 (32 to 37 weeks). Similarly, 57 cases of normal preterm infants were divided into Control group 1 and Control group 2. Levels of interleukin-6 (IL-6), MMP-9, and TIMP-1 were detected by enzyme-linked immunosorbent assay. Spearman's linear correlation was used to analyze the relationship between dependent variables. Pathological changes were examined by hematoxylin and eosin (HE) staining and in amniotic fluid smears. RESULTS Levels of IL-6, MMP-9, and TIMP-1, and the MMP-9/TIMP-1 ratio were significantly higher in the FIRS group than in the Control groups. IL-6 was positively correlated with MMP-9, TIMP-1, and the MMP-9/TIMP-1 ratio. Areas under the curve (AUC) of MMP-9, TIMP-1, and the MMP-9/TIMP-1 ratio were 0.92, 0.90, and 0.95, respectively. HE staining and amniotic fluid smears showed the aggregation of inflammatory cells. MMP-9, TIMP-1, and the MMP-9/TIMP-1 ratio were closely related to the incidence of BPD (≤32 weeks) and myocardial injury (<37 weeks) in preterm infants. CONCLUSION MMP-9, TIMP-1, and the MMP-9/TIMP-1 ratio revealed a certain diagnostic value for FIRS; combined with gestational age, these parameters were effective for predicting cardiopulmonary injury.

Abstract
Background Zinc oxide nanoparticles (ZnO-NPs) are widely used in many industrial sectors and previous studies have reported that exposure of the lungs to ZnO-NPs induces both acute and/or chronic pulmonary inflammation, but the exact mechanism underlying such response remains elusive. This study investigated the role of nuclear factor-erythroid 2-related factor (Nrf2) in pulmonary inflammation induced by exposure to ZnO-NPs using Nrf2 null (Nrf2−/−) mice. Methods Twenty-four male Nrf2−/− mice and thirty male wild type C57BL/6 J mice were divided into three groups of eight and ten each respectively, and exposed once to ZnO-NPs at 0, 10, 30 μg/mouse by pharyngeal aspiration. At 14 days after the exposure to ZnO-NPs, bronchoalveolar lavage fluid (BALF) and lungs were collected to quantify protein level and the number of inflammatory cells. The mRNA levels of Nrf2-dependent antioxidant enzymes and inflammatory cytokines in lung tissue were measured. Results Exposure to ZnO-NPs dose-dependently increased the number of total cells, macrophages, lymphocytes and eosinophils in BALF both in Nrf2−/− mice and wild type mice, but the magnitude of increase was significantly higher in Nrf2−/− mice than wild type mice. The number of neutrophils in BALF increased in Nrf2−/− mice, being accompanied by marginal trend of increase in mRNA expression of MIP-2, neutrophil chemoattractant, but such changes were not observed in wild type mice. Exposure to ZnO-NPs did not dose-dependently increase mRNA level of Nrf2-dependent antioxidant enzymes both in Nrf2−/− mice and wild type mice. Conclusion Pharyngeal aspiration of ZnO-NPs induced infiltration of inflammatory cells in the lung of mice, but minimally induced Nrf2-dependent antioxidant enzymes. The results suggest that Nrf2 play a role in negative regulation on ZnO-NP exposure-induced neutrophil migration, but does not demonstrate that the regulation is through suppression of oxidative stress.

Abstract
Adaptive support ventilation (ASV) is a closed-loop ventilation, which can make automatic adjustments in tidal volume (VT) and respiratory rate based on the minimal work of breathing. The purpose of this research was to study whether ASV can provide a protective ventilation pattern to decrease the risk of ventilator-induced lung injury in patients of acute respiratory distress syndrome (ARDS). In the clinical study, 15 ARDS patients were randomly allocated to an ASV group or a pressure-control ventilation (PCV) group. There was no significant difference in the mortality rate and respiratory parameters between these two groups, suggesting the feasible use of ASV in ARDS. In animal experiments of 18 piglets, the ASV group had a lower alveolar strain compared with the volume-control ventilation (VCV) group. The ASV group exhibited less lung injury and greater alveolar fluid clearance compared with the VCV group. Tissue analysis showed lower expression of matrix metalloproteinase 9 and higher expression of claudin-4 and occludin in the ASV group than in the VCV group. In conclusion, the ASV mode is capable of providing ventilation pattern fitting into the lung-protecting strategy; this study suggests that ASV mode may effectively reduce the risk or severity of ventilator-associated lung injury in animal models.

Abstract
Pulmonary fibrosis (PF) is a heterogeneous pathological process in lung tissues with a considerable mortality rate. Currently, combination therapy represents an effective approach to treat PF. Dexamethasone (Dxs) and berberine (BBR) are widely applied to inhibit the progression of PF. Dxs plus penehyclidine hydrochloride or alfacalcidol have been reported more effective in therapy compared with any single drug treatment. However, whether Dxs plus BBR induces an increased antifibrotic effect remains unknown. The current study aimed to evaluate the therapeutic effect of BBR plus Dxs in bleomycin (BLM)-induced PF. A PF model in rats was established and rats were divided into control, BLM, BBR, Dxs and BBR plus Dxs groups (n=9/group). On days 3, 7 and 14, blood samples were collected from the eyes of the rats (n=6/group). CXC chemokine ligand 14 (CXCL14), collagen I, collagen III, matrix metalloproteinase (MMP)2 and MMP9 serum levels were measured by ELISA. On day 14, all rats were sacrificed. Hematoxylin and eosin analysis, Masson staining and hydroxyproline (Hyp) assessment were performed to observe histopathological changes and collagen deposition. mRNA and protein levels of CXCL14, CXC chemokine receptor 4 (CXCR4), collagen I/III, α-smooth muscle actin (α-SMA), MMP2/9 and phosphorylated-Smad 2/3 in lung tissue were further evaluated. Similar effects in preventing lung damage were observed histopathologically for Dxs and BBR compared with the BLM group. These treatments further reduced levels of Hyp, CXCL14, CXCR4, collagen I/III, MMP2/9, α-SMA and p-Smad 2/3. The combination of Dxs and BBR exhibited increased effectiveness compared with the single treatments. Results further suggested that antifibrotic mechanisms were involved in inhibiting CXCL14 and MMP2/MMP9 expression, and preventing the activation of Smad2/3 and hedgehog signaling pathways. The combined use of Dxs and BBR may represent a potential therapeutic approach for PF.

Int Immunopharmacol 2019; 72:243-251.

Abstract
Paraquat (PQ), a highly toxic herbicide, selectively accumulates in the lungs and causes pulmonary damage through oxidative and inflammatory processes after intentional or accidental poisoning. The resulting acute lung injury (ALI) is characterized by neutrophil infiltration and extensive inflammation with rapid respiratory failure. However, effective therapies are lacking. We tested the hypothesis that suppressing neutrophil-derived matrix metalloproteinase 9 (MMP9) would ameliorate the inflammatory milieu and alleviate PQ-induced ALI. Lung injury was assessed in mice intratracheally injected with PQ aerosol by measuring the lung static compliance, cell count and neutrophil percentage of the bronchoalveolar lavage fluid (BALF) and lung, alveolar-capillary permeability, and histopathological lung injury scores. MMP9/2 activity was assessed by gelatin zymography, and the location of neutrophils and MMP9 in the lung was evaluated by immunofluorescence costaining. In the neutrophil depletion experiment, mice received anti-Ly6G antibody intraperitoneally; for the MMP inhibition experiment, an MMP inhibitor, doxycycline (DOX), was administered by gavage. In PQ-induced ALI, the activity of neutrophil-derived MMP9 but not MMP2 increased significantly. Neutrophil depletion reduced the inflammatory burden, improved pulmonary edema, and reduced the PQ-induced overexpression of MMP9. Consistently, oral delivery of DOX to mice decreased the overexpression of MMP9 that was activated by PQ and phenocopied the resolution of PQ-induced ALI observed after neutrophil depletion. Taken together, our results show for the first time that DOX is involved in the resolution of PQ-induced ALI via a mechanism involving reducing the activity of neutrophil-derived MMP9. We speculate that DOX may represent a novel therapeutic strategy for PQ-induced ALI.

Abstract
OBJECTIVE RNA interference was used to silence geranylgeranyltransferase Ⅰ(GGTase-Ⅰ) in vitro and to study the effect of GGTase-Ⅰ on the migration and invasion of tongue squamous cancer cells. METHODS Three small interfering RNAs (siRNA) were designed according to the GGTase-Ⅰ sequence by Genebank and were transfected into tongue squamous cancer cells Cal-27 to knock down GGTase-Ⅰ expression. The tested cells were divided into three groups, as follows: the RNA-interfered groups (GGTase-Ⅰ siRNA1, GGTase-Ⅰ siRNA 2, GGTase-Ⅰ siRNA 3), a negative control group (disrupted by random sequence NC-siRNA), and a blank control group. GGTase-Ⅰ and RhoA gene expressions were examined by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. The optimum interference group was screened by qRT-PCR and Western blot and was assigned as the experimental group. Matrix metalloproteinase (MMP)-2 and MMP-9 protein expressions were examined by Western blot. GTP-RhoA expression of protein was examined by GST-pull down. The migration and invasion abilities were analyzed by wound healing assay and Transwell motility assay. RESULTS GGTase-Ⅰ mRNA and protein expression in Cal-27 decreased significantly after transfection of GGTase-I siRNA (P<0.05). No significant difference of RhoA gene expression was detected. MMP-2, MMP-9, and GTP-RhoA protein expressions decreased significantly (P<0.05). The migration and invasion abilities were inhibited (P<0.05). CONCLUSIONS To inhibit GGTase-Ⅰ expression, the migration and invasion abilities of tongue squamous cancer cells should also be inhibited. Further studies on GGTase-Ⅰ may provide novel effective molecular targets for tongue squamous cancer cells.

Cryptotanshinone Ameliorates Radiation-Induced Lung Injury in Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:1908416. [PMID: 30915142 PMCID: PMC6402207 DOI: 10.1155/2019/1908416] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Revised: 12/21/2018] [Accepted: 01/16/2019] [Indexed: 02/07/2023]
Abstract
Cryptotanshinone (CTS) was reported to repress a variety of systemic inflammation and alleviate cardiac fibrosis, but it is still unclear whether CTS could prevent radiation-induced lung injury (RILI). Here, we investigated the effects and underlying mechanisms of CTS on a RILI rat model. Our data revealed that CTS could efficiently preserve pulmonary function in RILI rats and reduce early pulmonary inflammation infiltration elicited, along with marked decreased levels of IL-6 and IL-10. Moreover, we found that CTS is superior to prednisone in attenuating collagen deposition and pulmonary fibrosis, in parallel with a marked drop of HYP (a collagen indicator) and α-SMA (a myofibroblast marker). Mechanistically, CTS inhibited profibrotic signals TGF-β1 and NOX-4 expressions, while enhancing the levels of antifibrotic enzyme MMP-1 in lung tissues. It is noteworthy that CTS treatment, in consistent with trichrome staining analysis, exhibited a clear advantage over PND in enhancing MMP-1 levels. However, CTS exhibited little effect on CTGF activation and on COX-2 suppression. Finally, CTS treatment significantly mitigated the radiation-induced activation of CCL3 and its receptor CCR1. In summary, CTS treatment could attenuate RILI, especially pulmonary fibrosis, in rats. The regulation on production and release of inflammatory or fibrotic factors IL-6, IL-10, TGF-β1, NOX-4, and MMP-1, especially MMP-1 and inhibition on CCL3/CCR1 activation, may partly attribute to its attenuating RILI effect.

Abstract
The current study investigated the ability of two secoiridoids, GL-3 (1) and oleonuezhenide (2), isolated from the fruits of Ligustrum japonicum to inhibit MMP-2 and -9 activity in phorbol 12-myristate 13-acetate (PMA)-induced HT-1080 human fibrosarcoma cells. Both compounds1 and 2 were able to exert lowered gelatin digestion activity for MMP-2 and -9 tested by gelatin zymography via suppressing the release of MMPs to culture medium according to ELISA results. Treatment with compounds was also able to suppress the expression of both mRNA and protein levels of MMP-2 and -9. Action mechanism behind the MMP inhibitory effect of the compounds was suggested to be via MAPK pathway indicated by decreased levels of phosphorylated p38, ERK and JNK proteins evaluated employing immunoblotting. Compound 1 was shown to be slightly more active to inhibit MMP-2 and -9, however, compound 2 showed more regular dose-dependency during inhibition. In conclusion, this study suggested that GL-3 and oleonuezhenide were notable natural origin potent MMP inhibitors and could serve as lead compounds for development of anti-invasive MMP inhibitors against tumor metastasis.

Abstract
Brain metastases originating from lung adenocarcinoma (LAD) occur frequently. The aim of the current study was to assess potential biomarkers for the prognosis of lung adenocarcinoma brain metastasis (LAD-BM) through the analysis of gene expression microarrays. The current study downloaded two gene expression datasets, GSE14108 and GSE10245, from the Gene Expression Omnibus database. From GSE14108 and GSE10245, 19 LAD-BM samples and 40 primary LAD samples were selected for analysis. To identify the differentially expressed genes (DEGs), the current study compared the two sample groups, using the limma R package. Subsequently, pathway enrichment analysis was conducted using the Cluster Profiler R package, and the construction of the protein-protein interaction (PPI) network was executed utilizing the Search Tool for the Retrieval of Interacting Genes database. The microRNA-target network was built using the TargetScore R package. Then, these networks were established and visualized using Cytoscape software. An array of 463 DEGs was identified in the LAD-BM samples, including 256 upregulated and 207 downregulated genes. Based on functional term enrichment analysis using the Gene Ontology database and signaling pathway enrichment analysis using the Kyoto Encyclopedia of Genes and Genomes database, it was identified that the overlapping DEGs were primarily involved in chemokine-associated signal transduction, which may mediate lung cancer cell metastasis to the brain. Chemokine ligand 2, lysozyme, matrix metalloproteinase-2 (MMP-2), lysyl oxidase (LOX) and granzyme B were identified as potential biomarkers according to a topological analysis of the PPI networks. Two notable nodes, MMP-2 and LOX, appeared in the PPI network and were key points in the microRNA-target network, as they were regulated by hsa-let-7d. Many DEGs and microRNAs were regarded as prognostic biomarkers for lung adenocarcinoma metastasis in the current study. These DEGs were primarily associated with chemokine-mediated signaling pathways. In addition, MMP-2 and LOX were predicted to be targets of hsa-let-7d.

Abstract
Introduction: Roots of Asparagus cochinchinensis, which have pharmacologically active ingredients, have received great attention because they show good therapeutic effects for various inflammatory diseases without specific toxicity. This study investigated the anti-asthmatic effects of a butanol extract of Asparagus cochinchinensis roots that had been fermented with Weissella cibaria (BAW) and its possible underlying cholinergic regulation. Methods: Alterations of the anti-asthmatic markers and the molecular response factors were measured in an ovalbumin (OVA)-induced asthma model after treatment with BAW. Results: Treatment with BAW decreased the intracellular reactive oxygen species (ROS) production in lipopolysaccharides (LPS) activated RAW264.7 cells. The results of the animal experiments revealed lower infiltration of inflammatory cells and bronchial thickness, and a significant reduction in the number of macrophages and eosinophils, concentration of OVA-specific IgE, and expression of Th2 cytokines in the OVA + BAW treated group. In addition, a significant recovery of goblet cell hyperplasia, MMP-9 expression, and the VEGF signaling pathway was observed upon airway remodeling in the OVA + BAW treated group. Furthermore, these responses of BAW were linked to recovery of acetylcholine esterase (AChE) activity and muscarinic acetylcholine receptor (mAChR) M3 downstream signaling pathway in epithelial cells, smooth muscle cells, and afferent sensory nerves of OVA + BAW-treated mice. Conclusion: Overall, these findings are the first to provide evidence that the therapeutic effects of BAW can prevent airway inflammation and remodeling through the recovery of cholinergic regulation in structural cells and inflammatory cells of the chronic asthma model.

Abstract
BACKGROUND The epidermal growth factor receptor (EFGR) mutation was closely related to the invasion and metastasis of lung adenocarcinoma and the biological axis of CXCR4/CXCL12 (chemokine receptor 4/chemokine ligand 12) played an important role in the organ-specific metastasis of the tumor. It was a question surrounding whether there is interaction between them in the process of lung adenocarcinoma metastasis. To investigate the potential molecular mechanisms of EGFR over-expression and EFGR-mutations effects on cell proliferation, migration and invasion, we constructed EGFR over-expression and three EFGR-mutant human lung adenocarcinoma H1299 cell sublines. METHODS EGFR over-expression and three EFGR-mutant (EGFR-E746-A750del, EGFR-T790M and EGFR-L858R) plasmid were designed and transfected H1299 cells with Lipofectamine 2000. H1299 cells transfected with empty vector were negative control (NC), and H1299 cells without transfection were set as blank control (BC). The effects of EGFR over-expression and mutations on the proliferation, migration and invasion of H1299 cells were detected by cell cloning assay, wound healing assay and Transwell assay. The mRNA and protein expression levels of MMP-2, MMP-9, CXCR4 and CXCL12 were detected by RT-PCR and Western blot. RESULTS Compared with negative control group and blank control group, EGFR over-expression and EGFR-E746-A750 deletion have significantly higher colony formation (28±2, 28.33±4.16; respectively) (P<0.05) and the cell migration and invasion ability were significantly increased (P<0.05). RT-PCR and Western blot assay showed that the mRNA and protein expression of MMP-2, MMP-9, CXCR4 and CXCL12 in EGFR over-expression and EGFR-E746-A750 deletion group were remarkably higher than that in negative control and blank control group (P<0.05). CONCLUSIONS EGFR over-expression and 19 exon deletion can promote the expression of MMP-2 and MMP-9 by up-regulating CXCR4/CXCL12 signaling pathway, leading to the change of tumor biological characteristics such as higher proliferation, migration and invasion ability.

Abstract
Transforming growth factor β1 (TGF-β1), a multifunctional cytokine, is known to promote tumor invasion and metastasis and induce epithelial-mesenchymal transition (EMT) in various cancer cells. Inhibition of TGF-β1 signaling is a new strategy for cancer therapy. Most cancer cells display altered or nonfunctional TGF-β1 signaling; hence, TGF-β1 inhibitors exert limited effects on these cells. Recent studies have suggested that developing a TGF-β1 inhibitor from natural compounds is a key step to create novel therapeutic agents. This study aimed to develop a new anti-TGF-β1 therapy for cancer. We found an improved analog of chalcones, compound 67, and investigated its effects in vitro. We demonstrated the inhibitory role of compound 67 through migration and invasion assays on TGF-β1-induced EMT of human A549 lung cancer cells. Compound 67 inhibited TGF-β1-induced smad2 phosphorylation, suppressed TGF-β1-induced EMT markers, matrix metalloproteinase-2 (MMP-2) and MMP-9, and inhibited migration and invasion of A549 cells. The study results showed that compound 67 is useful to prevent tumor growth and metastasis.

Abstract
Matrix metalloproteinase-2 (MMP-2) is a potential target in anticancer drug discovery due to its association with angiogenesis, metastasis and tumour progression. In this study, 67 glutamic acid derivatives, synthesized and evaluated as MMP-2 inhibitors, were taken into account for multi-QSAR modelling study (regression-based 2D-QSAR, classification-based LDA-QSAR, Bayesian classification QSAR, HQSAR, 3D-QSAR CoMFA and CoMSIA as well as Open3DQSAR). All these QSAR studies were statistically validated individually. Regarding the 3D-QSAR analysis, the Open3DQSAR results were better than CoMFA and CoMSIA, although all these 3D-QSAR models supported each other. The importance of biphenylsulphonyl moiety over phenylacetyl/naphthylacetyl moieties was established due to its association with favourable steric and hydrophobic characters. HQSAR, LDA-QSAR and Bayesian classification QSAR studies also suggested that the biphenylsulphonamido group was better than the phenylacetylcarboxamido function. Additionally, glutamines were proven to be far better inhibitors than isoglutamines. Observations obtained from the current study were revalidated and supported by the earlier reported molecular modelling studies. Depending on these observations, newer glutamic acid-based compounds may be designed further in future for potent MMP-2 inhibitory activity.

Abstract
Extracellular matrix (ECM) is an essential component of the tissue microenvironment, actively shaping cellular behavior. In vitro culture systems are often poor in ECM constituents, thus not allowing for naturally occurring cell-ECM interactions. This study reports on a straightforward and efficient method for the generation of ECM scaffolds from lung tissue and its subsequent in vitro application using primary lung cells. Mouse lung tissue was subjected to decellularization with 0.2% sodium dodecyl sulfate, hypotonic solutions, and DNase. Resultant ECM scaffolds were devoid of cells and DNA, whereas lung ECM architecture of alveolar region and blood and airway networks were preserved. Scaffolds were predominantly composed of core ECM and ECM-associated proteins such as collagens I-IV, nephronectin, heparan sulfate proteoglycan core protein, and lysyl oxidase homolog 1, among others. When homogenized and applied as coating substrate, ECM supported the attachment of lung fibroblasts (LFs) in a dose-dependent manner. After ECM characterization and biocompatibility tests, a novel in vitro platform for three-dimensional (3D) matrix repopulation that permits live imaging of cell-ECM interactions was established. Using this system, LFs colonized the ECM scaffolds, displaying a close-to-native morphology in intimate interaction with the ECM fibers, and showed nuclear translocation of the mechanosensor yes-associated protein (YAP), when compared with cells cultured in two dimensions. In conclusion, we developed a 3D-like culture system, by combining an efficient decellularization method with a live-imaging culture platform, to replicate in vitro native lung cell-ECM crosstalk. This is a valuable system that can be easily applied to other organs for ECM-related drug screening, disease modeling, and basic mechanistic studies.

Integrative characterization of chronic cigarette smoke-induced cardiopulmonary comorbidities in a mouse model. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2017; 229:746-759. [PMID: 28648837 DOI: 10.1016/j.envpol.2017.04.098] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2016] [Revised: 02/24/2017] [Accepted: 04/06/2017] [Indexed: 12/16/2023]
Abstract
Cigarette smoke-triggered inflammatory cascades and consequent tissue damage are the main causes of chronic obstructive pulmonary disease (COPD). There is no effective therapy and the key mediators of COPD are not identified due to the lack of translational animal models with complex characterization. This integrative chronic study investigated cardiopulmonary pathophysiological alterations and mechanisms with functional, morphological and biochemical techniques in a 6-month-long cigarette smoke exposure mouse model. Some respiratory alterations characteristic of emphysema (decreased airway resistance: Rl; end-expiratory work and pause: EEW, EEP; expiration time: Te; increased tidal mid-expiratory flow: EF50) were detected in anaesthetized C57BL/6 mice, unrestrained plethysmography did not show changes. Typical histopathological signs were peribronchial/perivascular (PB/PV) edema at month 1, neutrophil/macrophage infiltration at month 2, interstitial leukocyte accumulation at months 3-4, and emphysema/atelectasis at months 5-6 quantified by mean linear intercept measurement. Emphysema was proven by micro-CT quantification. Leukocyte number in the bronchoalveolar lavage at month 2 and lung matrix metalloproteinases-2 and 9 (MMP-2/MMP-9) activities in months 5-6 significantly increased. Smoking triggered complex cytokine profile change in the lung with one characteristic inflammatory peak of C5a, interleukin-1α and its receptor antagonist (IL-1α, IL-1ra), monokine induced by gamma interferon (MIG), macrophage colony-stimulating factor (M-CSF), tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) at months 2-3, and another peak of interferon-γ (IFN-γ), IL-4, 7, 13, 17, 27 related to tissue destruction. Transient systolic and diastolic ventricular dysfunction developed after 1-2 months shown by significantly decreased ejection fraction (EF%) and deceleration time, respectively. These parameters together with the tricuspid annular plane systolic excursion (TAPSE) decreased again after 5-6 months. Soluble intercellular adhesion molecule-1 (sICAM-1) significantly increased in the heart homogenates at month 6, while other inflammatory cytokines were undetectable. This is the first study demonstrating smoking duration-dependent, complex cardiopulmonary alterations characteristic to COPD, in which inflammatory cytokine cascades and MMP-2/9 might be responsible for pulmonary destruction and sICAM-1 for heart dysfunction.

Abstract
Epithelial-to-mesenchymal transition (EMT), an important cellular process, occurs during cancer development and progression, has a crucial role in metastasis by enhancing the motility of tumor cells. Dioscin is a polyphenolic component isolated from Phyllanthus amarus, which exhibits a wide range of pharmacological and physiological activities, such as anti-tumor, anti-inflammatory, anti-obesity, anti-fungal, and anti-viral activities. However, the possible role of dioscin in the EMT is unclear. We investigated the suppressive effect of dioscin on the EMT. Transforming growth factor-beta 1 (TGF-β1) is known to induce EMT in a number of cancer cell types and promote lung adenocarcinoma migration and invasion. To verify the inhibitory role of dioscin in lung cancer migration and invasion, we investigated the use of dioscin as inhibitors of TGF-β1-induced EMT in A549 lung cancer cells in vitro. Here, we found that dioscin prominently increased expression of the epithelial marker E-cadherin and expression of the mesenchymal marker N-cadherin and Snail during the TGF-β1-induced EMT. In addition, dioscin inhibited the TGF-β1-induced increase in cell migration and invasion of A549 lung cancer cells. Also, dioscin remarkably inhibited TGF-β1-regulated activation of MMP-2/9, Smad2, and p38. Taken together, our findings provide new evidence that dioscin suppresses lung cancer migration, and invasion in vitro by inhibiting the TGF-β1-induced EMT.

Pulmonary microRNA profiling: implications in upper lobe predominant lung disease. Clin Epigenetics 2017; 9:56.

Abstract
Background Numerous pulmonary diseases manifest with upper lobe predominance including cystic fibrosis, smoking-related chronic obstructive pulmonary disease, and tuberculosis. Zonal hypoxia, characteristic of these pulmonary maladies, and oxygen stress in general is known to exert profound effects on various important aspects of cell biology. Lung macrophages are major participants in the pulmonary innate immune response and regional differences in macrophage responsiveness to hypoxia may contribute in the development of lung disease. MicroRNAs are ubiquitous regulators of human biology and emerging evidence indicates altered microRNA expression modulates respiratory disease processes. The objective of this study is to gain insight into the epigenetic and cellular mechanisms influencing regional differences in lung disease by investigating effect of hypoxia on regional microRNA expression in the lung. All studies were performed using primary alveolar macrophages (n = 10) or bronchoalveolar lavage fluid (n = 16) isolated from human subjects. MicroRNA was assayed via the NanoString nCounter microRNA assay. Results Divergent molecular patterns of microRNA expression were observed in alternate lung lobes, specifically noted was disparate expression of miR-93 and miR-4454 in alveolar macrophages along with altered expression of miR-451a and miR-663a in bronchoalveolar lavage fluid. Gene ontology was used to identify potential downstream targets of divergent microRNAs. Targets include cytokines and matrix metalloproteinases, molecules that could have a significant impact on pulmonary inflammation and fibrosis. Conclusions Our findings show variant regional microRNA expression associated with hypoxia in alveolar macrophages and BAL fluid in the lung—upper vs lower lobe. Future studies should address whether these specific microRNAs may act intracellularly, in a paracrine/endocrine manner to direct the innate immune response or may ultimately be involved in pulmonary host-to-pathogen trans-kingdom cross-talk.

Abstract
Pulmonary fibrosis is associated with irreversible, or partially reversible, airflow obstruction and ultimately unresponsiveness to asthma therapies such as corticosteroids. Intranasal curcumin, an anti-inflammatory molecule, has been found effective in allergic asthma. To study the effect of intranasal curcumin on airway remodeling and fibrosis in murine model of chronic asthma, BALB/c mice were sensitized to ovalbumin (OVA) and exposed to OVA aerosol (2%) from day 21 (after sensitization) for 5 weeks (twice/week). Curcumin (intranasal) was administered during the OVA aerosol challenge. Mice exposed to OVA developed inflammation dominated by eosinophils which lead to fibrosis and airway remodeling. Intranasal administration of curcumin significantly inhibited airway inflammation and pulmonary fibrosis, where MMP-9 activities were decreased along with α-smooth muscle actin (α-SMA), MMP-9, TIMP-1, and eotaxin expressions. These results suggest that intranasal curcumin regulates airway inflammation and remodeling in chronic asthma.

Abstract
Purpose/Aim: Intravitreal bevacizumab (Avastin) is an irreversible vascular endothelial growth factor (VEGF) inhibitor used off-label to treat severe retinopathy of prematurity in extremely low gestational age neonates. VEGF and matrix metalloproteinases (MMPs) and the tissue inhibitors of metalloproteinases (TIMPs) participate in lung maturation. We tested the hypothesis that intravitreal bevacizumab enters the systemic circulation and has long-lasting effects on lung MMPs. MATERIALS AND METHODS Neonatal rats were exposed to: (1) hyperoxia (50% O2); (2) intermittent hypoxia (IH) (50% O2 with brief episodes of 12% O2); or (3) room air (RA) from birth (P0) to P14. At P14, the time of eye opening in rats, a single dose of Avastin (0.125 mg) was injected into the vitreous cavity of the left eye. A control group received equivalent volume saline. At P23 and P45, lung MMP-2 and MMP-9, and TIMP-1, and TIMP-2 were assessed in the lungs. RESULTS At P23, Avastin increased MMP-2, MMP-9, and TIMP-1 levels in the hyperoxia group but decreased TIMP-1 levels in the IH group. The ratios of MMP-2/TIMP-1 and MMP-9/TIMP-1 were significantly elevated at P23 in the IH group treated with Avastin. At P45, the levels of MMP-2 and MMP-9 remained elevated in the hyperoxia and IH groups treated with Avastin, while a rebound increase in TIMP-1 levels was noted in the IH group. CONCLUSIONS Avastin treatment in IH has lasting alterations in the balance between MMPs and their tissue inhibitors. These changes may lead to impaired alveologenesis and tissue damage consistent with bronchopulmonary dysplasia/chronic lung disease.

Abstract
Matrix metalloproteinases (MMPs) are implicated in many physiological and pathological processes, including contraction, migration, differentiation, and proliferation. These processes all involve cell phenotype changes, known to be accompanied by reorganization of actin cytoskeleton. Growing evidence indicates a correlation between MMP activity and the dynamics of actin system, suggesting their mutual regulation. Here, data on the influence of MMPs on the actin microfilament system, on the one hand, and the dependence of MMP expression and activation on the organization of actin structures, on the other hand, are reviewed. The different mechanisms of putative actin-MMP regulation are discussed.

Abstract
Fermented black ginseng (FBG) is processed by the repeated steaming and drying of fresh ginseng followed by fermentation with Saccharomyces cerevisiae. It is known to possess anti‑oxidative effects. Skin wrinkle formation is associated with oxidative stress and inflammatory reactions. The aim of this study was to determine whether FBG possesses anti‑wrinkle activity using human fibroblasts (HS68). According to the Korea Ministry of Food and Drug Safety (MFDS) guidelines for the evaluation of the efficacy of functional anti‑wrinkle cosmetics, we attempted to elucidate the effects of FBG on type I procollagen, matrix metalloproteinase (MMP)‑1, MMP‑2, MMP‑9 and tissue inhibitor of metalloproteinase‑2 (TIMP‑2). In addition, the eye irritation potential of FBG was examined using the EpiOcular‑EIT kit. Our results revealed that FBG was not cytotoxic at concentrations <10 µg/ml. It was considered as safe for the eyes at concentrations of up to 100 µg/ml. Treatment with FBG at concentrations from 0.3 to 10 µg/ml significantly (P<0.05) increased the type I procollagen expression levels from 117.61±1.51 to 129.95±4.47% in the human fibroblasts. By contrast, FBG significantly (P<0.05) decreased the MMP‑1 expression level from 18.41±4.95 to 27.41±3.96%. FBG at 3 µg/ml also increased the expression of TIMP‑2 up to 154.55%. However, FBG at 10 µg/ml decreased the expression levels of MMP‑2 and MMP‑9 to 45.15 and 66.65%, respectively. These results suggest that FBG has potential anti‑wrinkle effects as a potential ingredient in cosmetics.

Abstract
Primary spontaneous pneumothorax (PSP) is a common benign problem. However, PSP recurrence is still a troublesome complication for most patients. This study intended to determine the role of matrix metalloproteinase-2 (MMP-2) and MMP-9 in type II pneumocytes of patients with PSP and its relation with recurrence. Ninety-one patients who had undergone needlescopic video-assisted thoracoscopic surgery wedge resection of lung with identifiable blebs for PSP were included in this study. Immunohistochemical (IHC) staining was used to measure the expression of MMP-2 and MMP-9 in lung tissues of PSP patients. The results were further correlated with clinicopathological parameters and recurrence rates using chi-square or Fisher's exact test. The value of MMP-2 and MMP-9 for overall recurrence was analyzed by univariate and multivariable Cox regression model. IHC data revealed that MMP-2 and MMP-9 staining was predominantly observed in type II pneumocytes of patients with PSP. We found that MMP-2 and MMP-9 expression in PSP, especially male PSP patients, was significantly correlated with recurrence. In the univariate and multivariate analyses, MMP-2 and MMP-9 were statistically significant risk factors for overall recurrence in PSP patients. Therefore, high expression levels of MMP-2 and MMP-9 in type II pneumocytes show a positive correlation with PSP recurrence risk. Further studies are needed to validate whether reduction of MMP-2 and MMP-9 expression may be a promising way for decreasing the risk of PSP recurrence in the future.

Abstract
Feline injection-site sarcoma (FISS) is an aggressive tumor believed to arise from the proliferation of fibroblasts and myofibroblasts in areas of chronic inflammation, particularly at sites of injection. Local recurrence is frequent after surgical excision. Gelatinases (MMP-2 and MMP-9) and their inhibitor (TIMP-2) are endopeptidases pivotal in extracellular matrix remodeling and therefore in tumor invasiveness. The aim of this study was to investigate the immunohistochemical expression of MMP-2, MMP-9, and TIMP-2 in FISS to assess their usefulness as prognostic factors. Size, soft tissue sarcoma (STS) grading system, depth of infiltration, surgical margins, and Ki-67 index were evaluated as additional prognostic markers. Twenty-four cases of primary FISS were classified according to clinical follow-up as nonrecurrent (NR, n = 14; 58.3%) and recurrent (R, n = 10; 41.7%). MMP-2, MMP-9, and TIMP-2 were variably expressed in the FISS examined, confirming their role in tumor invasiveness, yet they did not show significant differences between the R and NR groups. These results could be due to different tumor stages or to the multiple activities of these enzymes, not limited to ECM remodeling. The immunohistochemical expression of these enzymes considered alone does not seem to be useful as a prognostic marker. STS grading system, depth of infiltration, surgical margins, and Ki-67 index did not relate to recurrence. Instead, the size of the tumor, measured after formalin fixation, with an optimal cutoff of 3.75 cm (accuracy = 86%; P < .05), and the mitotic count, with an optimal cutoff of 20 mitoses/10 HPF (accuracy = 80%; P < .05), could be evaluated as useful prognostic markers.

Abstract
Fucoidan is a type of sulfated polysaccharide isolated from seaweed. The present study used ovariectomized Sprague‑Dawley rats, which were treated with fucoidan. The effects of fucoidan on bone metabolism, density and microarchitecture were assessed using micro‑computed tomography (CT), histomorphometric analysis, biochemical markers of bone metabolism (Serum procollagen type I N propeptide and C‑terminal telopeptide‑1) and tests of mechanical competence of the femur. In addition, the effects of low‑molecular weight fucoidan (LMWF) on in vitro cultured osteoclasts were examined, in order to determine the mechanisms underlying LMWF‑induced osteoclastic inhibition. In ovariectomized rats, LMWF increased femoral bone density. Micro‑CT scan also revealed that LMWF prevented microarchitectural deterioration and histomorphometric analysis determined that LMWF increased trabecular bone number and reduced the surface of bone resorption. In addition, LMWF reduced the high bone turnover rate, and improved the mechanical properties of the femur in ovariectomized rats. In vitro experiments revealed that LMWF inhibited the receptor activator of nuclear factor κB ligand (RANKL) and macrophage colony‑stimulating factor‑induced differentiation of RAW264.7 cells into tartrate‑resistant acid phosphatase (TRAP)‑positive osteoclasts, and reduced the bone resorption surface of the osteoclasts. Reverse transcription‑quantitative polymerase chain reaction demonstrated that LMWF inhibited mRNA expression of TRAP, matrix metallopeptidase‑9, nuclear activator of activated T‑cells 1, and osteoclast‑associated immunoglobulin‑like receptor, which are components of the signaling pathway for osteoclast differentiation. LMWF had no effect on RANK mRNA expression. In conclusion, the present study confirmed that LMWF inhibited osteoclast differentiation and bone resorption, and may be a potential treatment for osteoporosis in ovariectomized rats.

Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) is a common benign disorder. However, unpredictable recurrence is a major concern for most patients. The aim of the present study was to assess the role of matrix metalloproteinase-2 (MMP-2) and MMP-9 in alveolar macrophages of patients with PSP and its relationship with recurrence. METHODS Ninety-two patients who received needlescopic video-assisted thoracoscopic surgery (NVATS) wedge resection of lung with identifiable blebs for PSP were enrolled for the study. Immunohistochemistry was performed to evaluate the expression of MMP-2 and MMP-9 in lung tissues of patients with PSP. The result was correlated with clinicopathological variables and recurrence rates by the chi-square test. The value of MMP-2 and MMP-9 for overall recurrence was evaluated by univariate and multivariable Cox regression analyses. RESULTS The MMP-2 and MMP-9 staining was predominantly observed in alveolar macrophages of patients with PSP. We found that MMP-2 (recurrence: P<0.001; smoking status: P=0.029) and MMP-9 (recurrence: P=0.001; smoking status: P=0.045) expression in PSP, especially male patients, was significantly correlated with recurrence and smoking status. In the multivariate analyses, MMP-2 [hazard ratio (HR) =2.83; 95% confidence interval (CI): 1.37-5.85, P=0.005) and MMP-9 (HR =2.25; 95% CI: 1.19-4.24, P=0.013) were statistically significant risk factors for overall recurrence in PSP patients. CONCLUSIONS High expression levels of MMP-2 and MMP-9 showed a positive correlation with recurrence in PSP patients. Further studies are required to test whether inhibition of MMP-2 and MMP-9 expression renders a promising approach for reducing the risk of PSP recurrence in the future.

Abstract
Most mortality and morbidity following exposure to vesicants such as sulfur mustard is due to pulmonary toxicity. Acute injury is characterized by epithelial detachment and necrosis in the pharynx, trachea and bronchioles, while long-term consequences include fibrosis and, in some instances, cancer. Current therapies to treat mustard poisoning are primarily palliative and do not target underlying pathophysiologic mechanisms. New knowledge about vesicant-induced pulmonary disease pathogenesis has led to the identification of potentially efficacious strategies to reduce injury by targeting inflammatory cells and mediators including reactive oxygen and nitrogen species, proteases and proinflammatory/cytotoxic cytokines. Therapeutics under investigation include corticosteroids, N-acetyl cysteine, which has both mucolytic and antioxidant properties, inducible nitric oxide synthase inhibitors, liposomes containing superoxide dismutase, catalase, and/or tocopherols, protease inhibitors, and cytokine antagonists such as anti-tumor necrosis factor (TNF)-α antibody and pentoxifylline. Antifibrotic and fibrinolytic treatments may also prove beneficial in ameliorating airway obstruction and lung remodeling. More speculative approaches include inhibitors of transient receptor potential channels, which regulate pulmonary epithelial cell membrane permeability, non-coding RNAs and mesenchymal stem cells. As mustards represent high priority chemical threat agents, identification of effective therapeutics for mitigating toxicity is highly significant.

Abstract
BACKGROUND After flexor tendon injury and repair, adhesion formation is a substantial concern, as it can result in loss of motion and functional disability. Matrix metalloproteinase 9 (Mmp9) is a gelatinase that contributes to degradation of extracellular matrix and is expressed during flexor tendon healing. Mmp9(-/-) mice have accelerated remodeling of adhesions during flexor tendon healing, relative to wild-type mice. The purpose of this study was to investigate whether Ro 32-3555, an Mmp9 inhibitor, can improve flexor tendon healing by limiting adhesion formation or enhancing remodeling of scar tissue during murine flexor tendon healing. METHODS Flexor digitorum longus laceration and repair was performed in female C57BL/6J mice. Mice were treated with vehicle or the Mmp9 inhibitor Ro 32-3555 for 8 days. Analysis was performed for digit range of motion and gliding function, biomechanics, gene expression, and Mmp9 activity. RESULTS An Mmp9 activity assay and zymography confirmed suppression of Mmp9 activity in mice treated with Ro 32-3555. There was no significant difference in tendon gliding or range of motion between vehicle and Ro 32-3555-treated mice. There was also no difference in tendon biomechanical properties between the two groups. CONCLUSION Local inhibition of Mmp9 gelatinolytic activity at the flexor tendon repair site is insufficient to alter adhesion formation, remodeling of adhesions, or mechanical properties of healing murine flexor tendons.

Abstract
Rationale. Matrix metalloproteinase-9 (MMP-9) expression is upregulated in alveolar macrophages (AM) of HIV1+ smokers who develop emphysema. Knowing that lung epithelial lining fluid (ELF) of HIV1+ smokers contains increased levels of inflammatory cytokines compared to HIV1− smokers, we hypothesized that upregulation of lung cytokines in HIV1+ smokers may be functionally related to increased MMP-9 expression. Methods. Cytokine arrays evaluated cytokine protein levels in ELF obtained from 5 groups of individuals: HIV1− healthy nonsmokers, HIV1− healthy smokers, HIV1− smokers with low diffusing capacity (DLCO), HIV1+ nonsmokers, and HIV1+ smokers with low DLCO. Results. Increased levels of the Th17 related cytokine IL-23 were found in HIV1− smokers with low DLCO and HIV1+ smokers and nonsmokers. Relative IL-23 gene expression was increased in AM of HIV1+ individuals, with greater expression in AM of HIV1+ smokers with low DLCO. Infection with HIV1 in vitro induced IL-23 expression in normal AM. IL-23 stimulation of AM/lymphocyte cocultures in vitro induced upregulation of MMP-9. Lung T lymphocytes express receptor IL-23R and interact with AM in order to upregulate MMP-9. Conclusion. This mechanism may contribute to the increased tissue destruction in the lungs of HIV1+ smokers and suggests that Th17 related inflammation may play a role.

Part Fibre Toxicol 2016; 13:27.

Abstract
Background Multi-walled carbon nanotubes (MWCNT) are currently under intense toxicological investigation due to concern on their potential health effects. Current in vitro and in vivo data indicate that MWCNT exposure is strongly associated with lung toxicity (inflammation, fibrosis, granuloma, cancer and airway injury) and their effects might be comparable to asbestos-induced carcinogenesis. Although fibrosis is a multi-origin disease, epithelial-mesenchymal transition (EMT) is recently recognized as an important pathway in cell transformation. It is known that MWCNT exposure induces EMT through the activation of the TGF-β/Smad signalling pathway thus promoting pulmonary fibrosis, but the molecular mechanisms involved are not fully understood. In the present work we propose a new mechanism involving a TGF-β-mediated signalling pathway. Methods Human bronchial epithelial cells were incubated with two different MWCNT samples at various concentrations for up to 96 h and several markers of EMT were investigated. Quantitative real time PCR, western blot, immunofluorescent staining and gelatin zymographies were performed to detect the marker protein alterations. ELISA was performed to evaluate TGF-β production. Experiments with neutralizing anti-TGF-β antibody, specific inhibitors of GSK-3β and Akt and siRNA were carried out in order to confirm their involvement in MWCNT-induced EMT. In vivo experiments of pharyngeal aspiration in C57BL/6 mice were also performed. Data were analyzed by a one-way ANOVA with Tukey’s post-hoc test. Results Fully characterized MWCNT (mean length < 5 μm) are able to induce EMT in an in vitro human model (BEAS-2B cells) after long-term incubation at sub-cytotoxic concentrations. MWCNT stimulate TGF-β secretion, Akt activation and GSK-3β inhibition, which induces nuclear accumulation of SNAIL-1 and its transcriptional activity, thus contributing to switch on the EMT program. Moreover, a significant increment of nuclear β-catenin - due to E-cadherin repression and following translocation to nucleus - likely reinforces signalling for EMT promotion. In vivo results supported the occurrence of pulmonary fibrosis following MWCNT exposure. Conclusions We demonstrate a new molecular mechanism of MWCNT-mediated EMT, which is Smad-independent and involves TGF-β and its intracellular effectors Akt/GSK-3β that activate the SNAIL-1 signalling pathway. This finding suggests potential novel targets in the development of therapeutic and preventive approaches.

Abstract
Treatment of bovine pulmonary artery smooth muscle cells with endothelin-1 (ET-1) caused an increase in the expression and activation of proMMP-2 in the cells. The present study was undertaken to determine the underlying mechanisms involved in this scenario. We demonstrated that (i) pretreatment with NADPH oxidase inhibitor, apocynin; PKC-α inhibitor, Go6976; p(38)MAPK inhibitor SB203580 and NF-κB inhibitor, Bay11-7082 inhibited the expression and activation of proMMP-2 induced by ET-1; (ii) ET-1 treatment to the cells stimulated NADPH oxidase and PKCα activity, p(38)MAPK phosphorylation as well as NF-κB activation by translocation of NF-κBp65 subunit from cytosol to the nucleus, and subsequently by increasing its DNA-binding activity; (iii) ET-1 increases MT1-MMP expression, which was inhibited upon pretreatment with apocynin, Go6976, SB293580, and Bay 11-7082; (iv) ET-1 treatment to the cells downregulated TIMP-2 level. Although apocynin and Go6976 pretreatment reversed ET-1 effect on TIMP-2 level, yet pretreatment of the cells with SB203580 and Bay 11-7082 did not show any discernible change in TIMP-2 level by ET-1. Overall, our results suggest that ET-1-induced activation of proMMP-2 is mediated via cross-talk between NADPH oxidase-PKCα-p(38)MAPK and NFκB-MT1MMP signaling pathways along with a marked decrease in TIMP-2 expression in the cells.

Abstract
CONTEXT Previous research has found relationships between sulfur mustard (SM) toxicity and its adverse effects. OBJECTIVE SM is highly toxic to the respiratory system, leading to hacking cough, rhinorrheachest tightness, acute pharyngitis and laryngitis, chronic bronchitis and lung fibrosis. In this review, based on the scientific literature, we provide an updated summary of information on SM exposures and their differences with asthma and COPD. METHOD Information of this review was obtained by searching Medline/PubMed, ScienceDirect, Scopus, Google Scholar, ISI Web of Knowledge and Chemical Abstracts. RESULTS SM exposure can decrease pulmonary function tests (PFTs) values. In addition, inflammatory cell accumulation in the respiratory tract and increased expression of some pro-inflammatory cytokines including tumor necrosis factor-α (TNFα), IL-1a, IL-1β, and reactive oxygen radicals due to SM exposure have been shown. Matrix metalloproteinase (MMP) which degrade extracellular matrix proteins, contributing to inflammatory cell recruitment, tissue injury and fibrosis are also up-regulated in the lung after SM exposure. In the lung, SM exposure also can cause serious pathological changes including airway inflammation, parenchymal tissue destruction and airway obstruction which can lead to asthma or chronic obstructive pulmonary disease (COPD). Following SM poisoning, DNA damage, apoptosis and autophagy are observed in the lung along with the increased expression of activated caspases and DNA repair enzymes. CONCLUSION In the present article, respiratory symptoms, changes in PFTs, lung pathology and lung inflammation due to SM exposure and the similarities and differences between them and those observed in asthma and COPD were reviewed.

Abstract
In the epithelial-mesenchymal transition (EMT), an important cellular process, epithelial cells become mesenchymal cells. This process is also critically involved in cancer metastasis. Sanguiin H6 is a compound derived from ellagitannin, which is found in berries. Sanguiin H6 shows various pharmacological properties, including anti-angiogenic activity. Because the possible role of sanguiin H6 in the EMT and the underlying molecular mechanisms are unclear, we investigated the effect of sanguiin H6 on the EMT. Transforming growth factor-beta 1 (TGF-β1) induces the EMT and promotes lung adenocarcinoma migration and invasion through the Smad2/3 signaling pathway. Thus, to understand the inhibitory effects of sanguiin H6 on lung cancer migration and invasion, we investigated the ability of sanguiin H6 to inhibit TGF-β1-induced EMT in the A549 cell line. We found that sanguiin H6 significantly prevented the activation of Smad2/3 signaling pathway by TGF-β1. Additionally, sanguiin H6 increased the expression of the epithelial marker E-cadherin and repressed the expression of Snail and the mesenchymal marker N-cadherin during TGF-β1-induced EMT. Moreover, sanguiin H6 regulated the expression of EMT-dependent genes induced by TGF-β1. Finally, sanguiin H6 inhibited the migration and invasion of TGF-β1-stimulated A549 cells. Taken together, our findings provide new evidence that sanguiin H6 suppresses lung cancer migration and invasion in vitro by inhibiting TGF-β1 induction of the EMT.

Abstract
During viral infections, chemokines guide activated effector T cells to infection sites. However, the cells responsible for producing these chemokines and how such chemokines recruit T cells are unknown. Here, we show that the early recruitment of neutrophils into influenza-infected trachea is essential for CD8(+) T cell-mediated immune protection in mice. We observed that migrating neutrophils leave behind long-lasting trails that are enriched in the chemokine CXCL12. Experiments with granulocyte-specific CXCL12 conditionally depleted mice and a CXCR4 antagonist revealed that CXCL12 derived from neutrophil trails is critical for virus-specific CD8(+) T cell recruitment and effector functions. Collectively, these results suggest that neutrophils deposit long-lasting, chemokine-containing trails, which may provide both chemotactic and haptotactic cues for efficient CD8(+) T cell migration and localization in influenza-infected tissues.

Abstract
OBJECTIVE To investigate the relationship between matrix metalloproteinase 9 (MMP-9) gene polymorphism and the efficacy of glucocorticoid therapy in idiopathic pulmonary fibrosis (IPF) patients. METHODS We conducted a case-control study. Between January 2013 and September 2014, 115 patients at the Nine Department of Respiratory Medicine, Nanjing Chest Hospital, diagnosed with IPF were enrolled to be the IPF group and 100 healthy subjects were enrolled to be the control group. Prednisone was used to treat IPF patients. Polymerase chain reaction-restriction fragment length polymorphism was used to identify MMP-9 1562C> T polymorphism. The Sandwich enzyme-linked immunosorbent assay was used to measure the serum level of MMP-9 and tissue inhibitor of metalloproteinases 1 (TIMP-1) in the IPF patients before and after the glucocorticoid treatment. RESULTS The frequencies of the TT genotype and the T allele of MMP-9 1562C> T gene were found significantly higher in the IPF group compared with the control group (both p < 0.05). Serum levels of MMP-9 and TIMP-1 in IPF patients in each of the three genotype groups before glucocorticoid treatment were significantly higher than those in the control group (all p < 0.05). After the glucocorticoid treatment, MMP-9 and TIMP-1 levels decreased significantly compared with the levels before the glucocorticoid treatment in the IPF patients in each genotype group (all p < 0.05), but were still higher than those in the control group (all p < 0.05). The proportion of "remarkable effect" in the IPF patients of the CC genotype group was significantly higher than that in the other two genotype groups, while the rate of adverse reactions of the CC group was significantly lower than the other two groups (all p < 0.05). CONCLUSION MMP-9 gene 1562C> T polymorphism may affect the efficacy of the glucocorticoid therapy for IPF and may be a predictor of IPF treatment outcome.

Abstract
Ig-Hepta/GPR116 is a member of the G protein-coupled receptor family predominantly expressed in the alveolar type II epithelial cells of the lung. Previous studies have shown that Ig-Hepta is essential for lung surfactant homeostasis, and loss of its function results in high accumulation of surfactant lipids and proteins in the alveolar space. Ig-Hepta knock-out (Ig-Hepta(-/-)) mice also exhibit emphysema-like symptoms, including accumulation of foamy alveolar macrophages (AMs), but its pathogenic mechanism is unknown. Here, we show that the bronchoalveolar lavage fluid obtained from Ig-Hepta(-/-) mice contains high levels of inflammatory mediators, lipid hydroperoxides, and matrix metalloproteinases (MMPs), which are produced by AMs. Accumulation of reactive oxygen species was observed in the AMs of Ig-Hepta(-/-) mice in an age-dependent manner. In addition, nuclear factor-κB (NF-κB) is activated and translocated into the nuclei of the AMs of Ig-Hepta(-/-) mice. Release of MMP-2 and MMP-9 from the AMs was strongly inhibited by treatment with inhibitors of oxidants and NF-κB. We also found that the level of monocyte chemotactic protein-1 is increased in the embryonic lungs of Ig-Hepta(-/-) mice at 18.5 days postcoitum, when AMs are not accumulated and activated. These results suggest that Ig-Hepta plays an important role in regulating macrophage immune responses, and its deficiency leads to local inflammation in the lung, where AMs produce excessive amounts of reactive oxygen species and up-regulate MMPs through the NF-κB signaling pathway.
