Enhanced Expression but Decreased Specific Activity of Matrix Metalloproteinase 10 (MMP-10) in Comparison with Matrix Metalloproteinase 3 (MMP-3) in Human Urinary Bladder Carcinoma. J Clin Med 2021; 10:jcm10163683. [PMID: 34441979 PMCID: PMC8397099 DOI: 10.3390/jcm10163683] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 08/04/2021] [Accepted: 08/16/2021] [Indexed: 12/30/2022] Open
Abstract
Human urinary bladder cancer is a huge worldwide oncological problem causing many deaths every year. The degradation of extracellular matrix (ECM) induced by molecules such as matrix metalloproteinases (MMPs) is one of the main factors influencing the process of metastasis origination. The MMP expression is tied to tumor aggressiveness, stage, and patient prognosis. The cleavage of constituent proteins is initiated and prolonged by matrix metalloproteinases, such as MMP-3 and MMP-10. The aim of this study was to evaluate the expression and activity of both MMPs in human urinary bladder cancer occurring at various stages of the disease. Tissue samples from patients with urinary bladder cancer were analyzed. Samples were collected from patients with a low- and high-grade cancer. Control tissue was collected from the site opposite to the tumor. DNA content, MMPs content, and activity of MMP-3 and MMP-10 were measured using ELISA and Western blot techniques. MMP-3 and MMP-10 occur in high molecular complexes in human urinary bladder in healthy and cancerous tissues. Particularly, in high-grade tumors, the content of MMP-10 prevails over MMP-3. The actual and specific activities vary in both grades of urinary bladder cancer; however, the highest activity for MMP-3 and MMP-10 was found in low-grade tissues. In conclusion, MMP-10 had a higher content, but a lower activity in all investigated tissues compared to MMP-3. Generally, obtained results demonstrated a contrary participation of MMP-3 and MMP-10 in ECM remodeling what may be crucial in the pathogenesis of human urinary bladder carcinoma.

Abstract
BACKGROUND AND OBJECTIVES Urothelial carcinomas (UC) of urinary bladder (UB) and upper urinary tract (UT) are heterogeneous diseases with high morbidity and mortality. We looked for genes with metalloendopeptidase activity in a published UBUC transcriptomic database (GSE31684):MMP-11 was the most significant, showing stepwise up-regulation. We analyzed MMP-11 expression and association with clinicopathologic factors and survival in our well-characterized cohort of UCs. METHODS We determined MMP-11 expression in 295 UBUCs and 340 UTUCs with immunohistochemistry, evaluated by H-score. In a retrospective study, MMP-11 expression was correlated with clinicopathologic features and with disease-specific survival (DSS) and metastasis-free survival (MeFS). The statistical significance was evaluated with univariate and multivariate analyses. RESULTS High MMP-11 expression was significantly associated with advanced pT status, nodal metastasis, high histological grade, vascular and perineural invasion, and frequent mitoses. In multivariate Cox regression analyses, which adjusted for standard clinicopathologic characteristics, MMP-11 expression was independently associated with cancer-specific mortality (hazard ratio [HR] in UTUC:3.027, P = 0.005; in UBUC: 2.631, P = 0.010) and with metastasis development (HR in UTUC:2.261, P = 0.018; in UBUC:1.801, P = 0.026). CONCLUSIONS MMP-11 overexpression is associated with aggressive tumor phenotype and unfavorable clinical outcome in UTUC and UBUC, suggesting it may serve as a novel prognostic and therapeutic target.

Best practices recommendations in the application of immunohistochemistry in the bladder lesions: report from the International Society of Urologic Pathology consensus conference. Am J Surg Pathol 2014; 38:e20-34.

Abstract
The bladder working group of the 2013 International Society of Urologic Pathology (ISUP) Conference on Best Practices Recommendation in the Application of Immunohistochemistry (IHC) in Urologic Pathology discussed 5 settings in which IHC is commonly used in clinical practice. With regard to markers for urothelial differentiation, the committee found that there is no ideal marker or established panel to confirm urothelial differentiation. On the basis of the differential diagnostic consideration, positivity for GATA3, CK20, p63, and either high-molecular weight cytokeratin (HMWCK) or cytokeratin (CK)5/6 is of value in proving urothelial differentiation in the appropriate morphologic and clinical context. With regard to the role of IHC in the distinction of reactive atypia from urothelial carcinoma in situ, the committee recommended that morphology remains the gold standard in this differential diagnosis and that, at best, the IHC panel of CK20/p53/CD44(s) has potential utility but is variably used and has limitations. The immunostaining pattern must be interpreted with strict morphologic correlation, because overreliance on IHC may be misleading, particularly in the posttreatment setting. IHC has no role in the distinction of dysplasia versus carcinoma in situ and in the grading of papillary urothelial carcinoma. IHC may have a limited but distinct role in staging of bladder cancer. In a subset of cases, depending on the clinical and histologic context, broad-spectrum cytokeratins (to identify early or obscured invasion) and desmin (distinction of muscle from desmoplasia and to highlight muscle contours for subclassification) may be helpful. Limited experience and conflicting data preclude smoothelin or vimentin to be recommended routinely for subclassifying muscle type at this time. In the workup of a spindled cell proliferation of the bladder and in limited specimens, we recommend an immunohistochemical panel of 6 markers including ALK1, SMA, desmin, cytokeratin (AE1/AE3), and p63 with either of HMWCK or CK5/6. Currently, there are no prognostic immunohistochemical or molecular studies that are recommended to be routinely performed on biopsy or resection specimens.

Abstract
Matrix metalloproteinases (MMPs) have important roles in several cancer-supporting cellular processes, such as extracellular matrix (ECM) remodeling, angiogenesis, apoptosis, epithelial-to-mesenchymal transition and cell proliferation. This broad range of activity has led to considerable interest in the use of MMPs in the clinical setting as diagnostic or prognostic biomarkers and as therapeutic targets. Levels of the different MMPs can be measured in several sample types, including paraffin-embedded or fresh frozen tissue, serum, plasma and urine, and by various analytical methodologies, such as immunohistochemistry, real-time PCR, western and northern blot analyses, enzyme-linked immunosorbent assay and zymography. Several MMPs have been identified as having potential diagnostic or prognostic utility, whether alone or in combination with currently available diagnostic tests or imaging modalities. Although the early broad-spectrum anti-MMP agents showed a lack of efficacy, our continually improving understanding of the complex physiologic and pathologic roles of MMPs might enable the development of new MMP-specific and tumor-specific therapies. Accordingly, MMPs will continue to be the subjects of intensive research in bladder cancer.

Abstract
BACKGROUND Extracellular matrix metalloproteases (MMPs) have raised an extraordinary interest in cancer research because of their potential role in basal membrane and extracellular matrix degradation, consequently facilitating tumour invasion and metastases development. METHODS An immunohistochemical study was performed using tissue arrays and specific antibodies against MMPs 1, 2, 7, 9, 11, 13, 14, and their tissue inhibitors, TIMPs 1, 2 and 3. More than 2600 determinations on cancer specimens from 133 patients with clinically localised prostate carcinoma, 20 patients with prostatic intraepithelial neoplasia and 50 patients with benign prostate hyperplasia and controls, were performed. RESULTS When compared with benign pathologies, prostate carcinomas had higher expression of all MMPs and TIMPs. Dendogram shows a first-order division of tumours into two distinct MMPs/TIMPs molecular profiles, one of them with high MMPs/TIMs expression profile (n=70; 52.6%). Tumours with high expression of MMP-11 or -13, or cluster thereof, were significantly associated with higher probability of biochemical recurrence. CONCLUSION The expression of MMPs and TIMPs seems to have an important role in the molecular biology of prostate carcinomas, and their expression by tumours may be of clinical interest to used as indicators of tumour aggressiveness.

Abstract
Matrix metalloproteinase 11 (stromelysin-3) has recently been reported to play a key role in human tumor progression and poor clinical outcome. The aim of this study was to investigate the significance of matrix metalloproteinase 11 expression in gastric cancer. Using real-time quantitative reverse-transcription polymerase chain reaction analysis and immunohistochemistry, we studied matrix metalloproteinase 11 expression levels in non-malignant gastric tissues and in gastric cancer tissues. The association between matrix metalloproteinase 11 expression levels and tumor stage and grade, as well as metastatic potential, was analyzed. Our results show that matrix metalloproteinase 11 expression was significantly higher in gastric cancer specimens compared with nonmalignant tissues at both transcriptional and protein levels, indicating its positive role in the development of gastric cancer. In addition, increased matrix metalloproteinase 11 expression levels were associated with advanced-stage and high-grade tumors, suggesting its involvement in the progression of gastric cancer. More importantly, increased matrix metalloproteinase 11 expression in gastric cancer specimens was correlated with increased expression of IGF-1, a molecule known to stimulate the proliferation, enhanced survival, and migration of cancer cells. Our results demonstrate that matrix metalloproteinase 11 is a novel factor in the development and progression of gastric cancer and suggest that matrix metalloproteinase 11 is a marker for advanced gastric cancer.

Abstract
CONTEXT Invasion and the depth of invasion affect significantly the prognosis in urothelial carcinomas. The histopathologic evaluation of invasion may be problematic in some cases. Application of new immunohistochemical markers may facilitate the assessment of invasion. Fascin, one of these markers, is an actin-bundling protein involved in tumor cell migration. Fascin expression is increased in various carcinomas. Prior to this research, to our knowledge, only one study exists regarding fascin expression in urothelial carcinomas. OBJECTIVE To characterize the expression of fascin in additional cases of urothelial carcinoma and to verify statistically a relationship between fascin overexpression and invasiveness in these tumors. DESIGN We examined fascin immunoreactivity in 116 specimens of urothelial carcinomas obtained from 116 patients including 96 men and 20 women. Fifty-eight cases were ranked as low-grade carcinomas, pTa stage, and 58 cases were ranked as high-grade carcinomas--11 were ranked as stage pTa, 21 were ranked as pT1, and 26 were ranked as pT2 carcinomas. Fascin immunoreactivity was assessed semiquantitatively in tumor cells. In each case, we ascribed 3 immunoreactivity scores, one for extent, one for intensity, and a combined immunoreactivity score. RESULTS The combined immunoreactivity score was significantly higher in invasive carcinomas. In addition, strong staining was observed exclusively in invasive carcinomas. None of the pTa tumors demonstrated intense staining, including those ranked at the higher grade. CONCLUSIONS Our results point to an association between fascin immunostaining and urothelial carcinoma invasiveness and suggest that fascin overexpression may be a marker of aggressive urothelial carcinomas.

Abstract
OBJECTIVES To examine whether the circulating TIMP-2 or MMP-2:TIMP-2 complex associate with disease-free or cause-specific survival in bladder cancer patients. DESIGN AND METHODS Levels of circulating TIMP-2 and MMP-2:TIMP-2 complex from 50 patients and 44 healthy volunteers were measured by ELISA and compared with the clinical data. RESULTS In cancer patients the levels of TIMP-2 and MMP-2:TIMP-2 complex were significantly lower than in healthy volunteers (p= or <0.0001). Low TIMP-2 levels and low MMP-2:TIMP-2 complex levels correlated significantly with poor prognosis (p=0.0032, p=0.0022, respectively). The 5-year cause-specific survival rate was 67% and 60% in patients with a high serum level for TIMP-2 and MMP-2:TIMP-2 versus 18% and 20% in those with low levels of TIMP-2 and MMP-2:TIMP-2 complex. CONCLUSIONS The results indicate that TIMP-2 and MMP-2:TIMP-2 complex associate with favorable clinical course and could be used as a novel prognostic indicators in bladder cancer.

Abstract
The matrix metalloproteinases (MMPs) are endopeptidases which break down the extracellular matrix and regulate cytokine and growth factor activity. Several MMPs have been implicated in the promotion of invasion and metastasis in a broad range of tumours including urothelial carcinoma. In this study, RNA from 132 normal bladder and urothelial carcinoma specimens was profiled for each of the 24 human MMPs, the four endogenous tissue inhibitors of MMPs (TIMPs) and several key growth factors and their receptors using quantitative real time RT–PCR. Laser capture microdissection (LCM) of RNA from 22 tumour and 11 normal frozen sections was performed allowing accurate RNA extraction from either stromal or epithelial compartments. This study confirms the over expression in bladder tumour tissue of well-documented MMPs and highlights a range of MMPs which have not previously been implicated in the development of urothelial cancer. In summary, MMP-2, MT1-MMP and the previously unreported MMP-28 were very highly expressed in tumour samples while MMPs 1, 7, 9, 11, 15, 19 and 23 were highly expressed. There was a significant positive correlation between transcript expression and tumour grade for MMPs 1, 2, 8, 10, 11, 12, 13, 14, 15 and 28 (P<0.001). At the same confidence interval, TIMP-1 and TIMP-3 also correlated with increasing tumour grade. LCM revealed that most highly expressed MMPs are located primarily within the stromal compartment except MMP-13 which localised to the epithelial compartment. This work forms the basis for further functional studies, which will help to confirm the MMPs as potential diagnostic and therapeutic targets in early bladder cancer.

Abstract
Stromelysin-3 (ST3) overexpression is associated with poor patient clinical outcome in numerous carcinomas. The ST3 is expressed by peritumoral fibroblast-like cells. Review of the literature shows that ST3 is an active partner of cancer cells along the whole natural cancer history, and is essential for optimal tumor development as it reduces death of cancer cells invading adjacent connective tissues at the primary tumor site. Paradoxically, ST3 lowers metastasis development in vivo in mice. However, this beneficial effect does not counterbalance the deleterious anti-apoptotic function of ST3.

Abstract
BACKGROUND Stromelysin-3 (ST3) that belongs to the metalloproteinase family is proposed to play a role in tumor invasion. The purpose of this work was to study the variation of ST3 expression in meningiomas. METHODS Twenty atypical meningiomas were retrieved from the Pathology Department's files at Hopital de Bellevue, Saint-Etienne, France. They were compared with 20 benign meningiomas randomly selected from the same file. The tumors were classified using standard histologic criteria. Frozen sections of the tumors were immunostained for ST3 and MIB-1 to evaluate the proliferative activity of tumor cells. RESULTS The study included 5 fibrous meningiomas, 10 transitional meningiomas, 20 syncitial meningiomas, 2 secretory meningiomas, 2 microcystic meningiomas, and 1 angiomatous meningioma. Stromelysin-3 was expressed within the stromal and neoplastic cells of only 1 benign meningioma and 13 atypical meningiomas. The MIB-1 proliferation index was significantly higher in the meningiomas expressing ST3 (Student t test: P < 0.001). The invasion of bone, muscle, and brain by meningiomas as well the recurrence were statistically correlated with their ST3 expression (Kruskal-Wallis nonparametric correlation test, P = 0.001 and P = 0.008, respectively). CONCLUSIONS Stromelysin-3 might play an important role in the invasiveness of meningiomas. Therefore, considering, ST3 in association with evaluation of the MIB-1 proliferating index may be an useful tool to assess the behavior of meningiomas.

Abstract
Adenomas with misplaced epithelium in the submucosa of the polyp stalk ("pseudoinvasion") may be difficult to distinguish from adenomas that harbor invasive adenocarcinoma by morphologic analysis. Recently, several epithelial and stromal proteins, such as matrix metalloproteinase-1 (MMP-1), p53, E-cadherin, and collagen IV, have been shown to be altered in colonic adenocarcinomas in comparison with adenomas and normal colonic mucosa. Therefore, the purpose of this study was to evaluate the diagnostic use of several epithelial (p53, E-cadherin) and stromal (MMP-1, collagen IV) markers in distinguishing adenomas with misplaced epithelium from those with invasive adenocarcinoma. Routinely processed polypectomy specimens from 23 patients with an adenoma with misplaced epithelium (male/female ratio 12/11; mean age 65 years) and 23 patients with an adenocarcinoma arising in an adenoma (male/female ratio 13/10; mean age 63 years) were immunohistochemically stained (avidin-biotin complex method) for monoclonal antibodies to MMP-1 (epithelial and stromal cell collagenase), p53 (tumor suppression gene), E-cadherin (intercellular adhesion protein), and collagen IV (basement membrane collagen component), and the results were compared between the two polyp groups. Where appropriate, immunopositivity was evaluated in the epithelium (MMP-1, p53, E-cadherin), stroma (MMP-1), and/or basement membrane (collagen IV). Cases were considered positive if an increase (MMP-1, p53) or decrease (E-cadherin, collagen IV) in either the intensity or proportion of cells staining was noted in the submucosal epithelial component compared with the intramucosal portion of the polyp head for each individual polyp. In adenomas with invasive adenocarcinoma, MMP-1 staining of the stroma surrounding submucosal epithelium and p53 nuclear staining within the epithelium were increased in 21 (91%) and 14 (61%) cases, respectively, whereas decreased or discontinuous E-cadherin and collagen IV staining was noted in 15 (65%) and 22 (96%) cases, respectively. All these values were significantly different (p < 0.005) from those observed in adenomas with misplaced epithelium [MMP-1, 11 of 23 (48%); p53, 1 of 23 (4%); E-cadherin, 0 of 23 (0%); collagen IV, 0/23 (0%)]. Furthermore, in three diagnostically difficult cases that contained foci of misplaced epithelium with high-grade dysplasia, the immunohistochemical results confirmed the impression that the lesions represented epithelial misplacement rather than invasive adenocarcinoma. In conclusion, the degree and/or pattern of MMP-1, p53, E-cadherin, and collagen IV staining in the submucosal epithelial elements in comparison with the intramucosal adenomatous tissue may help distinguish adenomas with misplaced epithelium from those with invasive adenocarcinoma.
