Abstract
The extracellular matrix remodeling in the skin results from a delicate balance of synthesis and degradation of matrix components, ensuring tissue homeostasis. These processes are altered during tumor invasion and growth, generating a microenvironment that supports growth, invasion, and metastasis. Apart from the cellular component, the tumor microenvironment is rich in extracellular matrix components and bound factors that provide structure and signals to the tumor and stromal cells. The continuous remodeling in the tissue compartment sustains the developing tumor during the various phases providing matrices and proteolytic enzymes. These are produced by cancer cells and stromal fibroblasts. In addition to fostering tumor growth, the expression of specific extracellular matrix proteins and proteinases supports tumor invasion after the initial therapeutic response. Lately, the expression and structural modification of matrices were also associated with therapeutic resistance. This review will focus on the significant alterations in the extracellular matrix components and the function of metalloproteinases that influence skin cancer progression and support the acquisition of therapeutic resistance.

Abstract
BACKGROUND Calcific aortic valve disease is a common cardiovascular disorder worldwide. This study aimed to investigate the correlation between plasma matrix metalloproteinase-28 (MMP-28) levels and the severity of calcific aortic valve stenosis. MATERIAL AND METHODS Calcific aortic valve stenosis patients who were admitted to the heart center of our hospital between January 2016 and January 2019 to undergo surgery were successively enrolled in this study (55 males and 24 females with an average age of 58.5±9.6). Information on echocardiography, plasma MMP-28 levels, and other clinical data of the patients was retrospectively collected. RESULTS The average plasma MMP-28 level was 2.43±2.22 ng/mL (range, 0.22-8.27 ng/mL). Plasma MMP-28 levels in patients with mild (n=24), moderate (n=31), or severe (n=24) aortic valve stenosis were 0.74 (0.25-2.23), 1.46 (0.50-3.22), and 4.13 (1.54-6.18) ng/mL, respectively, indicating that the patients with severe aortic valve stenosis had significantly higher MMP-28 levels than the patients with moderate or mild aortic valve stenosis (both P<0.01). Regression analysis using the general linear model further revealed that plasma MMP-28 level was correlated with the peak blood flow velocity and mean pressure gradient of the transaortic valve, and the correlations were statistically significant (both P<0.01). CONCLUSIONS MMP-28 level is significantly elevated in severe cases of calcific aortic valve stenosis. Moreover, plasma MMP-28 levels are positively correlated with the mean pressure gradients and peak blood flow velocity of the transaortic valve.

Circulating Matrix Metalloproteinase-28 Levels Are Related to GRACE Scores and Short-Term Outcomes in Patients with Acute Myocardial Infarction. BIOMED RESEARCH INTERNATIONAL 2020; 2020:9206703. [PMID: 32596395 PMCID: PMC7273487 DOI: 10.1155/2020/9206703] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 04/10/2020] [Accepted: 04/20/2020] [Indexed: 01/14/2023]
Abstract
Objective To investigate the relationship between the level of matrix metalloproteinase-28 (MMP-28) in patients with acute myocardial infarction (AMI) and the global registry of acute coronary events (GRACE) scores as well as their short-term prognosis. Methods Two hundred eleven patients with AMI were enrolled, and their basic clinical characteristics were collected for determining the GRACE score. We measured the plasma levels of MMP-28 and other biomarkers in the study population. The association of MMP-28 levels with cardiac events and cardiac deaths occurring within 30 days of discharge was evaluated with multivariable Cox proportional hazard models. Results The MMP-28 levels were significantly higher in patients with acute ST-elevation myocardial infarction (STEMI) than in patients with non-ST-elevation myocardial infarction (NSTEMI) (P < 0.01). Correlation analysis showed that the level of MMP-28 was positively correlated with the GRACE score in patients with AMI (R2 = 0.366, P < 0.05). Cox multivariate regression results showed that MMP-28 was associated with cardiovascular events during the hospitalization and 30 days after discharge (P < 0.01). In addition, Kaplan–Meier analysis showed that cardiac events and deaths were significantly higher in patients with MMP-28 ≥ 1.21 ng/mL (all P < 0.01). Conclusion There is a correlation between the plasma MMP-28 level and GRACE score in patients with AMI. MMP-28 is also associated with cardiovascular events and cardiovascular deaths during the hospitalization of patients and within 30 days of discharge.

Abstract
The aim of the present study was to assess the expression status of matrix metalloproteinase (MMP)-28 and to investigate its molecular mechanisms in glioma cells. MicroRNA (miRNA) reverse transcription-quantitative polymerase chain reaction was used to analyze the expression of MMP-28 and transforming growth factor (TGF)-β expression in glioma patients and healthy volunteers. MTT and Transwell assays were conducted to determine cell growth and metastasis, respectively. Annexin V/propidium iodide staining was also employed to measure cell apoptosis. MMP-28 and TGF-β protein expression were measured using western Blot analysis. The results indicated that MMP-28 and TGF-β expression was downregulated in glioma patients, when compared with the normal group. Overall survival and disease-free survival of patients with a low expression of MMP-28 were lower than those with high MMP-28 expression. Overexpression of MMP-28 induced TGF-β protein expression, while downregulation of MMP-28 suppressed TGF-β protein expression in glioma cell. The downregulation of MMP-28 reduced the cell growth and apoptosis of glioma cell via the suppression of TGF-β. By contrast, upregulation of MMP-28 induced cell growth and reduced the apoptosis of glioma cells by activating TGF-β. In addition, the TGF-β inhibitor attenuated the effects of MMP-28 in glioma cells. Collectively, the results indicated that MMP-28 was able to induce TGF-β in human glioma cells.

Abstract
AIM To detect the expression of eukaryotic translation initiation factor 3h (EIF3h), matrix metallopeptidase 10 (MMP-10), and matrix metallopeptidase 11 (MMP-11) in colonic adenocarcinoma and to analyze their clinical significance.
METHODS One hundred and ten colonic adenocarcinoma tissues, 43 high-grade colorectal intraepithelial neoplasia tissues, 43 low-grade colorectal intraepithelial neoplasia tissues, and 43 normal colonic mucosal tissues were collected. The expression of EIF3h, MMP-10, and MMP-11 in the above tissues was detected by immunohistochemistry.
RESULTS The expression of EIF3h, MMP-10, and MMP-11 differed significantly among the four groups. Expression of EIF3h, MMP-10, and MMP-11 was correlated with lymph node metastasis. Expression of EIF3h was correlated with tumor size, differentiation, proliferation index, and TNM stage. Expression of MMP-10 and MMP-11 was correlated with vascular invasion. There was a positive correlation between MMP-10 and MMP-11 expression in colonic adenocarcinoma.
CONCLUSION High expression and synergy of EIF3h, MMP-10, and MMP-11 can promote tumor formation and progression in colonic adenocarcinoma. EIF3h may be associated with the prognosis of colonic adenocarcinoma.

Overexpression of MMP21 and MMP28 is associated with gastric cancer progression and poor prognosis. Oncol Lett 2018; 15:7776-7782.

Abstract
Matrix metalloproteinase (MMP)-21 and MMP-28, or epilysin, are overexpressed during the invasion and metastasis of solid tumors. The present study investigated MMP-21 and MMP-28 expression levels in human gastric cancer using tissue microarray (TMA) analysis, and determined their association with clinicopathological characteristics and patient prognosis. TMA blocks, including 436 cases of gastric cancer and 92 non-cancerous adjacent gastric tissues, were investigated using immunohistochemistry. Staining results were analyzed statistically in association with various clinicopathological characteristics and overall survival. The MMP-21 and MMP-28 positive detection rate was 31.9% (139/436) and 34.4% (150/436), respectively, in the gastric carcinoma tissue specimens. MMP-21 and MMP-28 expression levels were negative in the 92 normal gastric tissue samples. In patients with gastric cancer, positive expression of MMP-21 and MMP-28 was correlated with tumor diameter, depth of invasion, vessel invasion, lymph node and distant metastases and tumor-node-metastasis stage. The overall survival rate was significantly lower in MMP-21 and MMP-28-positive compared with negative patients. Cox multivariate analysis revealed that MMP-21 and MMP-28 levels were independent predictors of survival in patients with gastric cancer. These findings emphasize the importance of MMP-21 and MMP-28, which may serve as novel and independent prognostic markers for the invasion and metastasis of human gastric cancer.

Abstract
Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that are involved in the degradation of various proteins in the extracellular matrix (ECM). Typically, MMPs have a propeptide sequence, a catalytic metalloproteinase domain with catalytic zinc, a hinge region or linker peptide, and a hemopexin domain. MMPs are commonly classified on the basis of their substrates and the organization of their structural domains into collagenases, gelatinases, stromelysins, matrilysins, membrane-type (MT)-MMPs, and other MMPs. MMPs are secreted by many cells including fibroblasts, vascular smooth muscle (VSM), and leukocytes. MMPs are regulated at the level of mRNA expression and by activation of their latent zymogen form. MMPs are often secreted as inactive pro-MMP form which is cleaved to the active form by various proteinases including other MMPs. MMPs cause degradation of ECM proteins such as collagen and elastin, but could influence endothelial cell function as well as VSM cell migration, proliferation, Ca2+ signaling, and contraction. MMPs play a role in tissue remodeling during various physiological processes such as angiogenesis, embryogenesis, morphogenesis, and wound repair, as well as in pathological conditions such as myocardial infarction, fibrotic disorders, osteoarthritis, and cancer. Increases in specific MMPs could play a role in arterial remodeling, aneurysm formation, venous dilation, and lower extremity venous disorders. MMPs also play a major role in leukocyte infiltration and tissue inflammation. MMPs have been detected in cancer, and elevated MMP levels have been associated with tumor progression and invasiveness. MMPs can be regulated by endogenous tissue inhibitors of metalloproteinases (TIMPs), and the MMP/TIMP ratio often determines the extent of ECM protein degradation and tissue remodeling. MMPs have been proposed as biomarkers for numerous pathological conditions and are being examined as potential therapeutic targets in various cardiovascular and musculoskeletal disorders as well as cancer.

Abstract
While commonly known for degradation of the extracellular matrix, matrix metalloproteinases (MMPs) exhibit broad potential for use in targeting of bioactive and imaging agents in cancer treatment. MMPs are upregulated at all stages of expression in cancers. A comprehensive analysis of published literature on expression of all MMP subtypes at the genetic, protein, and activity levels in normal and diseased tissues indicate targeting applicability in a variety of cancers. This expression significantly increases at advanced cancer stages, providing an improved opportunity for controlled release in higher-stage patients. Since MMPs are integral at every stage of metastasis, MMP roles in cancer are discussed with a focus on MMP distribution and mobility within cells and tumors for cancer targeting applications. Several strategies for MMP utilization in targeting - such as matrix degradation, MMP cleavage, MMP binding, and MMP-induced environmental changes - are addressed.

Abstract
BACKGROUND Laterality in the vertebrate embryo is determined by left-right asymmetric gene expression driven by the flow of extraembryonic fluid across the embryonic node. Defects in these processes cause heterotaxy, the abnormal formation and arrangement of visceral organs that can range from complete inversion of symmetry to the selective misarrangement of organs. However, our understanding of the genetic causality for laterality defects in human beings remains relatively limited. METHODS We performed whole exome sequencing in a consanguineous family with heterotaxia. To interrogate the pathogenic potential of the discovered variant, we used an in vivo system in which the potential of the candidate gene to induce L-R asymmetry was tested by transient suppression and CRISPR/Cas9-induced deletions. We also used in vitro assays to test a possible link between our exome-derived candidate and Notch signaling. RESULTS We identified a homozygous 2 bp deletion in MMP21, encoding matrix metalloproteinase-21, as the sole coding mutation that segregated with the phenotype. Transient suppression or CRISPR/Cas9-mediated deletion of mmp21 in zebrafish embryos induced cardiac looping defects, with concomitant disruption of laterality markers in the lateral plate mesoderm and disrupted notch signalling in vitro and in vivo. CONCLUSIONS Our data implicate loss of MMP21 as a cause of heterotaxy in humans with concomitant defects in Notch signaling. In support of this finding, a homozygous missense mutation in MMP21 was identified previously in mice with N-Ethyl-N-Nitrosourea (ENU)-induced heterotaxy. Taken together, these observations suggest a role of matrix metalloproteinases in the establishment of asymmetric organ development, likely through the regulation of morphogenetic signals.

Abstract
Matrix metalloproteinases, a group of over 26 zinc-dependent enzymes, share a similar structure to each other and functionally are capable of degrading almost every component of the extracellular matrix. They are essential to normal development during embryogenesis and extracellular matrix remodeling and, given this, understandably enough have been implicated in multiple pathologic processes that encompass the inflammatory and neoplastic spectrum of disease. This review attempts to define roles of matrix metalloproteinases of relevance in normal skin and to elucidate their roles in inflammatory dermatoses and benign and malignant neoplasms.

Abstract
Matrix metalloproteinase-21 (MMP-21) has been shown to enhance tumor invasion and metastasis ability in some solid tumors. In the present study, we investigated the expression of MMP-21 as well as its association with overall survival of gastric cancer patients. MMP-21 expression was investigated in 296 cases of gastric cancer by immunohistochemistry assay. Statistical analysis was utilized to evaluate the association of MMP-21 expression with overall survival of patients. MMP-21 expression was proved to be increased in gastric cancer compared with that in normal tissues (P < 0.05). It was also proved MMP-21 expression was associated with tumor invasion, metastasis and TNM stage (P < 0.001). MMP-21 expression was showed to be associated with overall survival of gastric cancer patients for patients with tumor of higher MMP-21 expression tend to have worse overall survival (P < 0.001). Multivariate analysis proved MMP-21 to be an independent prognostic factor for overall survival of gastric cancer patients (P < 0.001). These results suggested the potential role of MMP-21 in progression of human gastric cancer. It might also be a novel molecular marker to predict overall survival of patients with gastric cancer.

Abstract
Human matrix metalloproteinases (MMPs) belong to the M10 family of the MA clan of endopeptidases. They are ubiquitarian enzymes, structurally characterized by an active site where a Zn(2+) atom, coordinated by three histidines, plays the catalytic role, assisted by a glutamic acid as a general base. Various MMPs display different domain composition, which is very important for macromolecular substrates recognition. Substrate specificity is very different among MMPs, being often associated to their cellular compartmentalization and/or cellular type where they are expressed. An extensive review of the different MMPs structural and functional features is integrated with their pathological role in several types of diseases, spanning from cancer to cardiovascular diseases and to neurodegeneration. It emerges a very complex and crucial role played by these enzymes in many physiological and pathological processes.

Abstract
BACKGROUND The expression of matrix metalloproteinase-21 (MMP-21) has been shown to be elevated in some solid tumor and thought to enhance tumor invasion and metastasis ability. In the present study, we investigated the expression of MMP-21 and its association with prognosis in stage II and III colorectal cancer. METHODS MMP-21 expression was investigated in 286 cases of colorectal cancer by immunohistochemistry assay. Statistical analysis was utilized to evaluate the association of MMP-21 expression with clinicopathological characters and overall survival of patients with stage II and III colorectal cancer. RESULTS MMP-21 expression was significantly higher in colorectal cancer, compared with that in normal epithelial tissue. And it also correlated with tumor invasion, lymph node metastasis, and distant metastasis of colorectal cancer. MMP-21 was also proved to be an independent prognostic factor in patients with stage II as well as stage III colorectal cancer.

It could also be a novel molecular marker to predict prognosis of patients with stage II and stage III colorectal cancer.
