Deflamin Attenuated Lung Tissue Damage in an Ozone-Induced COPD Murine Model by Regulating MMP-9 Catalytic Activity. Int J Mol Sci 2024; 25:5063. [PMID: 38791100 PMCID: PMC11121448 DOI: 10.3390/ijms25105063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2024] [Revised: 04/26/2024] [Accepted: 05/04/2024] [Indexed: 05/26/2024] Open
Abstract
Chronic obstructive pulmonary disease (COPD) is comprised of histopathological alterations such as pulmonary emphysema and peribronchial fibrosis. Matrix metalloproteinase 9 (MMP-9) is one of the key enzymes involved in both types of tissue remodeling during the development of lung damage. In recent studies, it was demonstrated that deflamin, a protein component extracted from Lupinus albus, markedly inhibits the catalytic activity of MMP-9 in experimental models of colon adenocarcinoma and ulcerative colitis. Therefore, in the present study, we investigated for the first time the biological effect of deflamin in a murine COPD model induced by chronic exposure to ozone. Ozone exposure was carried out in C57BL/6 mice twice a week for six weeks for 3 h each time, and the treated group was orally administered deflamin (20 mg/kg body weight) after each ozone exposure. The histological results showed that deflamin attenuated pulmonary emphysema and peribronchial fibrosis, as evidenced by H&E and Masson's trichrome staining. Furthermore, deflamin administration significantly decreased MMP-9 activity, as assessed by fluorogenic substrate assay and gelatin zymography. Interestingly, bioinformatic analysis reveals a plausible interaction between deflamin and MMP-9. Collectively, our findings demonstrate the therapeutic potential of deflamin in a COPD murine model, and suggest that the attenuation of the development of lung tissue damage occurs by deflamin-regulated MMP-9 catalytic activity.

Zhan X, Jiang L, Wang L, Liu J, Kang S, Liu H, Lin L. A novel angiogenic effect of PCSK9- regulated genes. Gene X 2023; 852:147051. [PMID: 36427678 DOI: 10.1016/j.gene.2022.147051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 11/02/2022] [Accepted: 11/09/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Since the discovery of the Proprotein Convertase Subtilisin/Kexin Type 9(PCSK9) gene has been involved in regulating low-density lipoprotein metabolism and cardiovascular disease (CVD), many therapeutic strategies directly targeting PCSK9 have been introduced. PCSK9 gain of function (GoF) mutations are associated with autosomal dominant hypercholesterolemia (ADH) and premature atherosclerosis. In contrast, PCSK9 loss of function (LOF) mutations have cardioprotective effects and can lead to familial hypo cholesterol in some instances. However, its potential impacts beyond the typical effects on lipid metabolism have not been elucidated. Therefore the study aimed to identify and verify PCSK9's possible effects beyond its traditional role in lipid metabolism. METHODS The S127R is a PCSK9 gain of function mutation. Firstly, We used the data of the gene expression Omnibus(GEO) database to identify the differentially expressed genes between S127R mutation carriers and ordinary people. Secondly, the identification and analysis of significant genes were performed with various bioinformatics programs. Thirdly, to verify the possible effect and the potential pathways of PCSK9 on angiogenesis, we constructed PCSK9 low and high expression models by transfecting PCSK9-siRNA (small interfering RNA) and PCSK9-plasmid complex into human umbilical vein endothelial cells (HUVECs), respectively. Furthermore, Wound-Healing Assay and Capillary tube formation assay were applied to measure the effect of PCSK9 on angiogenesis. Fourthly, the expression level of VEGFR2 and the significant genes between PCSK9 low and high expression models were verified by quantitative real-time PCR. All data were analysed by GraphPad Prism 8 software. RESULTS 88 DEGs were identified, including 45 up-regulated and 43 down-regulated DEGs. Furthermore, we identified the six genes (MMP9, CASP3, EGR1, NGFR, LEFTY1 and NODAL) as significantly different genes between PCSK9-S127R and Control hiPSC. Further, we found that these significant difference genes were mainly associated with angiogenesis after enrichment analysis. To verify the possible effect of PCSK9 on angiogenesis, we constructed low and high-expression PCSK9 models by transfecting siRNA and PCSK9-plasmid complex into human umbilical vein endothelial cells (HUVECs), respectively. The tubule formation test and Wound healing assays showed that overexpression of PCSK9 had an inhibitory effect on angiogenesis, which could be reversed by decreasing the expression of PCSK9. Moreover, bioinformatics analysis indicated that the six hub genes (MMP9, CASP3, EGR1, NGFR, LEFTY1 and NODAL) might play a vital role in the biological function of PCSK9 in angiogenesis. Real-time quantitative PCR was applied to clarify the expression profiles of these critical genes in overexpression/knockdown PCSK9. Finally, the expression levels of MMP9, Caspase3, LEFTY1, and NODAL were suppressed by overexpression of PCSK9 and could be alleviated by PCSK9 knockdown. Otherwise, EGR1 had the opposite expression trend, and there was no specific trend of NGFR after repeated experiments. CONCLUSION PCSK9 might play an essential role in angiogenesis, unlike its typical role in lipid metabolism, and MMP9, Caspase3, LEFTY1, NODAL, and EGR1 may be involved in the regulation of angiogenesis as critical genes.

Abstract
Fibrillin-1 is a pivotal structural component of the kidney's glomerulus and peritubular tissue. Mutations in the fibrillin-1 gene result in Marfan syndrome (MFS), an autosomal dominant disease of the connective tissue. Although the kidney is not considered a classically affected organ in MFS, several case reports describe glomerular disease in patients. Therefore, this study aimed to characterize the kidney in the mgΔlpn-mouse model of MFS. Affected animals presented a significant reduction of glomerulus, glomerulus-capillary, and urinary space, and a significant reduction of fibrillin-1 and fibronectin in the glomerulus. Transmission electron microscopy and 3D-ultrastructure analysis revealed decreased amounts of microfibrils which also appeared fragmented in the MFS mice. Increased collagen fibers types I and III, MMP-9, and α-actin were also observed in affected animals, suggesting a tissue-remodeling process in the kidney. Video microscopy analysis showed an increase of microvessel distribution coupled with reduction of blood-flow velocity, while ultrasound flow analysis revealed significantly lower blood flow in the kidney artery and vein of the MFS mice. The structural and hemodynamic changes of the kidney indicate the presence of kidney remodeling and vascular resistance in this MFS model. Both processes are associated with hypertension which is expected to worsen the cardiovascular phenotype in MFS.

Abstract
Introduction-With the high global prevalence of prostate cancer and associated mortalities, it is important to enhance current clinical practices for better prostate cancer outcomes. The current review is towards understanding the value of Zn towards this mission. Method-General information on Zn in biology and multiple aspects of Zn involvement in prostate health and disease were referred to in PubMed. Results-The most influential feature of Zn towards prostate health is its ability to retain sufficient citrate levels for a healthy prostate. Zn deficiencies were recorded in serum, hair, and prostate tissue of men with prostate cancer compared to non-cancer controls. Zn gut absorption, albumin binding, and storage compete with various factors. There are multiple associations of Zn cellular influx and efflux transporters, Zn finger proteins, matrix metalloproteinases, and Zn signaling with prostate cancer outcomes. Such Zn marker variations associated with prostate cancer recorded from biological matrices may improve algorithms for prostate cancer screening, prognosis, and management when coupled with standard clinical practices. Discussion-The influence of Zn in prostatic health and disease is multidimensional, therefore more personalized Zn requirements may be beneficial. Several opportunities exist to utilize and improve understanding of Zn associations with prostate health and disease.

Abstract
OBJECTIVES 10-Methacryloyloxydecyl dihydrogen phosphate (MDP) has been regarded as the most effective dentin-bonding monomer for more than 20 years. Although the dentin-bonding promoting effect of MDP has been well demonstrated, the mechanisms by which it benefits the stably of collagen within the adhesive-dentin hybrid layer are not currently fully understood. The objective of this study was to investigate the roles of MDP and its calcium salt in preserving the adhesive-dentin hybrid layer. METHODS MDP-conditioned collagen was investigated by Fourier-transform infrared spectroscopy, Ultraviolet-visible spectroscopy, and molecular docking. The structural changes to the dentin surface upon acid-etching and MDP-conditioning were observed by SEM. X-ray diffraction and nuclear magnetic resonance were used to investigate the chemical interactions between MDP and HAp. The collagen-protecting effects of MDP and its Ca salt were investigated using in-situ zymography, rhMMP-9 colorimetric assay, hydroxyproline assay, and molecular docking. RESULTS MDP forms a stable collagen-phosphate complex through hydrogen bonding with the collagen in dentin. Furthermore, it generates MDP-Ca salts that are deposited on the dentin collagen scaffold, protecting it from degradation. Moreover, both free MDP and the MDP-Ca salt inhibit matrix metallopeptidase and exogenous proteases, with the inhibitory effect of the calcium salt being significantly stronger than that of the free form. SIGNIFICANCE MDP-based adhesives preserve the collagen within the hybrid layer by simultaneously improving collagen's resistance to exogenous enzymes and inhibiting MMP activity, both of which contribute to the longevity of dentin-resin bonding.

Abstract
Following a successful renal transplantation circulating markers of inflammation may remain elevated, and systemic inflammation is associated with worse clinical outcome in renal transplant recipients (RTRs). Vitamin D-receptor (VDR) activation is postulated to modulate inflammation and endothelial function. We aimed to explore if a synthetic vitamin D, paricalcitol, could influence systemic inflammation and immune activation in RTRs. Newly transplanted RTRs were included in an open-label randomized controlled trial on the effect of paricalcitol on top of standard care over the first post-transplant year. Fourteen pre-defined circulating biomarkers reflecting leukocyte activation, endothelial activation, fibrosis and general inflammatory burden were analyzed in 74 RTRs at 8 weeks (baseline) and 1 year post-engraftment. Mean changes in plasma biomarker concentrations were compared by t-test. The expression of genes coding for the same biomarkers were investigated in 1-year surveillance graft biopsies (n = 60). In patients treated with paricalcitol circulating osteoprotegerin levels increased by 0.19 ng/ml, compared with a 0.05 ng/ml increase in controls (p = 0.030). In graft tissue, a 21% higher median gene expression level of TNFRSF11B coding for osteoprotegerin was found in paricalcitol-treated patients compared with controls (p = 0.026). Paricalcitol treatment did not significantly affect the blood- or tissue levels of any other investigated inflammatory marker. In RTRs, paricalcitol treatment might increase both circulating and tissue levels of osteoprotegerin, a modulator of calcification, but potential anti-inflammatory treatment effects in RTRs are likely very modest.

Network pharmacology-based investigation on the mechanisms of action of Morinda officinalis How. in the treatment of osteoporosis. Comput Biol Med 2020; 127:104074. [PMID: 33126122 DOI: 10.1016/j.compbiomed.2020.104074] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 10/12/2020] [Accepted: 10/17/2020] [Indexed: 01/12/2023]
Abstract
BACKGROUND Osteoporosis is a systemic skeletal disease that leads to a high risk for bone fractures. Morinda officinalis How. has been used as osteoporosis treatment in China. However, its mechanism of action as an anti-osteoporotic herb remains unknown. METHODS A network pharmacology approach was applied to explore the potential mechanisms of action of M. officinalis in osteoporosis treatment. The active compounds of M. officinalis and their potential osteoporosis-related targets were retrieved from TCMSP, TCMID, SwissTargetPrediction, DrugBank, DisGeNET, GeneCards, OMIM, and TTD databases. A protein-protein interaction network was built to analyze the target interactions. The Metascape database was used to carry out GO enrichment analysis and KEGG pathway analysis. Moreover, interactions between active compounds and potential targets were investigated through molecular docking. RESULTS A total of 17 active compounds and 93 anti-osteoporosis targets of M. officinalis were selected for analysis. The GO enrichment analysis results indicated that the anti-osteoporosis targets of M. officinalis mainly play a role in the response to steroid hormone. The KEGG pathway enrichment analysis showed that M. officinalis prevents osteoporosis through the ovarian steroidogenesis signaling pathway. Moreover, the molecular docking results indicated that bioactive compounds (morindon, ohioensin A, and physcion) demonstrated a good binding ability with IGF1R, INSR, ESR1, and MMP9. CONCLUSION M. officinalis contains potential anti-osteoporotic active compounds. These compounds function by regulating the proteins implicated in ovarian steroidogenesis-related pathways that are crucial in estrogen biosynthesis. Our study provides new insights into the development of a natural therapy for the prevention and treatment of osteoporosis.

Abstract
Matrix metalloproteinase-9 (MMP-9) belongs to the MMP family and has been widely investigated. Excessive MMP-9 expression can enhance extracellular matrix degradation and promote plaque instability. Studies have demonstrated that MMP-9 levels are higher in vulnerable plaques than in stable plaques. Additionally, several human studies have demonstrated that MMP-9 may be a predictor of atherosclerotic plaque instability and a risk factor for future adverse cardiovascular and cerebrovascular events. MMP-9 deficiency or blocking MMP-9 expression can inhibit plaque inflammation and prevent atherosclerotic plaque instability. All of these results suggest that MMP-9 may be a useful predictive biomarker for vulnerable atherosclerotic plaques, as well as a therapeutic target for preventing atherosclerotic plaque instability. In this review, we describe the structure, function, and regulation of MMP-9. We also discuss the role of MMP-9 in predicting and preventing atherosclerotic plaque instability.

Matrix metalloproteinases (MMP) are key players in the remodelling of the extracellular matrix under physiological and pathological conditions. Thermodynamic parameters of human recombinant metalloproteinases of the active (rMMP2, 3, 7, 8 and 9) and latent (rPro-MMP2, 3 and 9) forms were obtained by differential scanning calorimetry (DSC). Temperature by itself does not result in autocatalysis of recombinant MMP. The transitions observed by DSC correspond to structural domains of the monomeric protein. In this study, we show the domain organization of these proteins, where the thermal transition (Tm) of the main component is observed at 71.3 °C (ProMMP-2); 74.8 °C (ProMMP-8); 80.0 °C (ProMMP-3); 92.6 °C (ProMMP-9) and 98.3 °C (ProMMP-7). For MMP-3, this main Tm is related to the catalytic domain (CD). The isolated recombinant CD of MMP-3 unfolds as a single transition at Tm 83.4 °C, matching the more stable domain observed in the full-length active form of rMMP-3. The denaturation profile of rProMMP-3 shows the main transition at Tm 80 °C, a less stable domain before the propeptide domain (PD) cleavage. Our results indicate that the structural stability of MMP and particularly their CD are not substantially altered after cleavage of the PD. We propose that the thermodynamic parameters obtained by DSC are relevant for the functional study of MMP, particularly to reveal their contribution in complex biological samples in health and disease.

Abstract
Aim: A breakthrough in modern medicine, in terms of treatment of Alzheimer’s disease, is yet to be seen, as the scene is currently plagued with numerous clinical trial failures. Here, we are exploring multifunctional hybrid sulfonamides for their anti-Alzheimer activity due to the complex nature of the disease. Results & methodology: Compound 41 showed significant inhibition of MMP-2 (IC50: 18.24 ± 1.62 nM), AChE (IC50: 4.28 ± 0.15 μM) and BuChE (IC50: 1.32 ± 0.02 μM). It also exhibited a metal-chelating property, as validated by an in vitro metal-induced Aβ aggregation assay using confocal fluorescence imaging. Whereas, MTT and DPPH assays revealed it to be nontoxic and neuroprotective with substantial antioxidant property. Conclusion: The present study puts forth potent yet nontoxic lead molecules, which foray into the field of multitargeted agents for the treatment of Alzheimer’s disease.

The inhibitory effect of carboxyl-terminated polyamidoamine dendrimers on dentine host-derived matrix metalloproteinases in vitro in an etch-and-rinse adhesive system. ROYAL SOCIETY OPEN SCIENCE 2019; 6:182104.

Abstract
The biomimetic remineralization of collagen fibrils has increased interest in restoring the demineralized dentine generated by dental caries. Carboxyl-terminated polyamidoamine dendrimers (PAMAM-COOH), hyperbranched polymeric macromolecules, can act as non-collagenous proteins to induce biomimetic remineralization on a dentine organic matrix. However, in vivo remineralization is an extremely time-consuming process; before complete remineralization, demineralized dentine collagen fibrils are susceptible to degradation by host-derived matrix metalloproteinases (MMPs). Therefore, we examined the effect of fourth-generation PAMAM-COOH (G4-PAMAM-COOH) on the collagenolytic activities of endogenous MMPs, the interaction between G4-PAMAM-COOH and demineralized dentine collagen and the influence of G4-PAMAM-COOH pre-treatment on resin-dentine bonding. G4-PAMAN-COOH not only inhibited exogenous soluble rhMMP9 but also hampered the proteolytic activities of dentine collagen-bound MMPs. Cooperated with the results of G4-PAMAM-COOH absorption and desorption, FTIR spectroscopy provided evidence for the exclusive electrostatic interaction rather than hydrogen or covalent bonding between G4-PAMAM-COOH and dentine collagen. Furthermore, G4-PAMAM-COOH pre-treatment showed no damage to resin-dentine bonding because it did not significantly decrease the elastic modulus of the demineralized dentine, degree of conversion, penetration of the adhesive into the dentinal tubules or ultimate tensile strength. Thus, G4-PAMAM-COOH can effectively inactivate MMPs, retard the enzymolysis of collagen by MMPs and scarcely influence the application of resin-dentine bonding.

Abstract
BACKGROUND Alzheimer's Disease (AD), a multifaceted disorder, involves complex pathophysiology and plethora of protein-protein interactions. Thus such interactions can be exploited to develop anti-AD drugs. OBJECTIVE The interaction of dynamin-related protein 1, cellular prion protein, phosphoprotein phosphatase 2A and Mint 2 with amyloid β, etc., studied recently, may have critical role in progression of the disease. Our objective has been to review such studies and their implications in design and development of drugs against the Alzheimer's disease. METHODS Such studies have been reviewed and critically assessed. RESULTS Review has led to show how such studies are useful to develop anti-AD drugs. CONCLUSION There are several PPIs which are current topics of research including Drp1, Aβ interactions with various targets including PrPC, Fyn kinase, NMDAR and mGluR5 and interaction of Mint2 with PDZ domain, etc., and thus have potential role in neurodegeneration and AD. Finally, the multi-targeted approach in AD may be fruitful and opens a new vista for identification and targeting of PPIs in various cellular pathways to find a cure for the disease.

Neurochem Res 2019; 44:1593-1601.

Abstract
Matrix metalloproteinase-9 (MMP-9, Gelatinase B), an extracellular-acting Zn2+-dependent endopeptidase, are involved in brain pathologies including ischemia, glioma, and epilepsy. Recent studies suggested that MMP-9 plays an important role in neuronal plasticity, specifically in learning and memory. To determine whether and how MMP-9 plays role in alcohol-related behaviors, male Sprague-Dawley (SD) rats were subjected to chronic intermittent ethanol (CIE) exposure for 4 weeks, following which we collected tissue samples from the hippocampus, medial prefrontal cortex (mPFC), and amygdala at different stages (acute and chronic exposure) during alcohol exposure. Real-time PCR and western blot assays were used to detect changes in the mRNA and protein expression of MMP-9. Our results indicated that both acute and chronic alcohol exposure induced up-regulation of MMP-9 mRNA levels in the hippocampus and mPFC, but not in the amygdala. Furthermore, acute and chronic alcohol exposure up regulated the expression of total MMP-9 and active MMP-9 in these two brain regions. Moreover, the increase of active MMP-9 expression was larger than those in total MMP-9 expression. Immunoprecipitation analyses identified potential MMP-9-interacting proteins, including Itgb1, Src, Eef1a2, tubulin, actin, and histone H2B. These results demonstrate that both acute and CIE exposure induced increases in MMP-9 expression in the mPFC and hippocampus, suggesting that MMP-9 plays a key role in chronic alcohol exposure and dependence.
