Abstract
For their full manifestation, tumors require support from the surrounding tumor microenvironment (TME), which includes a specific extracellular matrix (ECM), vasculature, and a variety of non-malignant host cells. Together, these components form a tumor-permissive niche that significantly differs from physiological conditions. While the TME helps to promote tumor progression, its special composition also provides potential targets for anti-cancer therapy. Targeting tumor-specific ECM molecules and stromal cells or disrupting aberrant mesenchyme-cancer communications might normalize the TME and improve cancer treatment outcome. The tenascins are a family of large, multifunctional extracellular glycoproteins consisting of four members. Although each have been described to be expressed in the ECM surrounding cancer cells, tenascin-C and tenascin-W are currently the most promising candidates for exploitability and clinical use as they are highly expressed in various tumor stroma with relatively low abundance in healthy tissues. Here, we review what is known about expression of all four tenascin family members in tumors, followed by a more thorough discussion on tenascin-C and tenascin-W focusing on their oncogenic functions and their potential as diagnostic and/or targetable molecules for anti-cancer treatment purposes.

Abstract
After the airways have been formed by branching morphogenesis the gas exchange area of the developing lung is enlarged by the formation of new alveolar septa (alveolarization). The septa themselves mature by a reduction of their double-layered capillary networks to single-layered ones (microvascular maturation). Alveolarization in mice is subdivided into a first phase (postnatal days 4-21, classical alveolarization), where new septa are lifted off from immature preexisting septa, and a second phase (day 14 to adulthood, continued alveolarization), where new septa are formed from mature septa. Tenascin-C (TNC) is a multidomain extracellular matrix protein contributing to organogenesis and tumorigenesis. It is highly expressed during classical alveolarization, but afterward its expression is markedly reduced. To study the effect of TNC deficiency on postnatal lung development, the formation and maturation of the alveolar septa were followed stereologically. Furthermore, the number of proliferating (Ki-67-positive) and TUNEL-positive cells was estimated. In TNC-deficient mice for both phases of alveolarization a delay and catch-up were observed. Cell proliferation was increased at days 4 and 6; at day 7, thick septa with an accumulation of capillaries and cells were observed; and the number of TUNEL-positive cells (dying cells or DNA repair) was increased at day 10. Whereas at days 15 and 21 premature microvascular maturation was detected, the microvasculature was less mature at day 60 compared with wild type. No differences were observed in adulthood. We conclude that TNC contributes to the formation of new septa, to microvascular maturation, and to cell proliferation and migration during postnatal lung development.NEW & NOTEWORTHY Previously, we showed that the extracellular matrix protein tenascin-C takes part in prenatal lung development by controlling branching morphogenesis. Now we report that tenascin-C is also important during postnatal lung development, because tenascin-C deficiency delays the formation and maturation of the alveolar septa during not only classical but also continued alveolarization. Adult lungs are indistinguishable from wild type because of a catch-up formation of new septa.

Abstract
BACKGROUND Tenascin-C is a matricellular protein related to brain injury. We studied serum tenascin-C in acute intracerebral hemorrhage (ICH) and examined the associations with severity and outcome following the acute event. METHODS Tenascin-C samples were obtained from 162 patients with acute hemorrhagic stroke and 162 healthy controls. Poor 90-day functional outcome was defined as modified Rankin Scale score > 2. Early neurological deterioration (END) and hematoma growth (HG) were recorded at 24 h. RESULTS Patients had higher tenascin-C levels than controls. Tenascin-C levels were positively correlated with hematoma volume or National Institutes of Health Stroke Scale score at baseline. Elevated tenascin-C levels were independently associated with END, HG, 90-day mortality and poor functional outcome. Moreover, tenascin-C levels significantly predicted END, HG and 90-day outcomes under receiver operating characteristic curves. CONCLUSIONS An increase in serum tenascin-C level is associated with an adverse outcome in ICH patients, supporting the potential role of serum tenascin-C as a prognostic biomarker for hemorrhagic stroke.

Abstract
Tenascin-C (TNC), an extracellular matrix glycoprotein, plays a pivotal role in tumor growth. However, the mechanism whereby TNC affects tumor biology remains unclear. To investigate the exact role of TNC in primary tumor growth, a mouse mammary tumor cell line, GLMT1, was first developed. Subsequently, global gene expression in GLMT1-derived tumors was compared between wild-type (WT) and TNC-knockout (TNKO) mice. Tumors in WT mice were significantly larger than those in TNKO mice. DNA microarray analysis revealed 447 up and 667 downregulated in the tumors inoculated into TNKO mice as compared to tumors in WT mice. Validation by quantitative gene expression analysis showed that Tnc, Cxcl1, Cxcl2, and Cxcr2 were significantly upregulated in WT mice. We hypothesize that TNC stimulates the CXCL1/2-CXCR2 pathway involved in cancer cell proliferation.

Abstract
BACKGROUND Tenascin-C, a matricellular protein, is involved in brain injury. However, change of tenascin-C concentrations in peripheral blood remains unknown after traumatic brain injury (TBI). METHODS Serum tenascin-C concentrations were measured in 100 healthy controls, 108 severe TBI patients, 79 moderate TBI patients and 32 mild TBI patients. RESULTS Serum tenascin-C concentrations of patients were significantly higher than those of controls. Tenascin-C concentrations negatively correlated with Glasgow Coma Scale (GCS) scores in all patients (r=-0.658, P<0.001). In severe TBI patients, tenascin-C in serum significantly discriminated patients at risk of 6-month mortality (area under curve, 0.821; 95% confidence interval, 0.735-0.888) and poor outcome (Glasgow Outcome Scale score of 1-3) (area under curve, 0.833; 95% confidence interval, 0.749-0.898) and emerged as an independent predictor for 6-month mortality (odds ratio, 1.114; 95% confidence interval, 1.008-1.233; P=0.005), overall survival (hazard ratio, 1.085; 95% confidence interval, 1.010-1.166; P=0.003) and unfavorable outcome (odds ratio, 1.049; 95% confidence interval, 1.014-1.076; P=0.001). By receiver-operating characteristic analysis, serum tenascin-C concentrations had similar prognostic value compared with GCS scores. CONCLUSIONS Enhanced serum tenascin-C concentrations are closely related to trauma severity and clinical outcomes, substantializing tenascin-C as a potential prognostic biomarker after TBI.

Abstract
Reactive stromal changes that occur in different human cancers might play a role in local tumor spreading and progression. Studies done on various human cancers have shown activated stromal cell phenotypes, modified extracellular matrix (ECM) composition, and increased microvessel density. Furthermore, they exhibit biological markers consistent with stroma at the site of wound repair. In prostate cancer, stroma is composed of fibroblasts, myofibroblasts, endothelial cells and immune cells. Predominant cells in the tumorous stroma are, however, fibroblasts/myofibroblasts. They are responsible for the synthesis, deposition and remodeling of the ECM. Epithelial tumorous cells, in interaction with stromal cells and with the help of various molecules of ECM, create a microenvironment suitable for cancer cell proliferation, movement, and differentiation. In this review, we discussed the role of different stromal components in prostate cancer as well as their potential prognostic and therapeutic significance.

Abstract
The extracellular matrix protein tenascin-C plays a critical role in development, wound healing, and cancer progression, but how it is controlled and how it exerts its physiological responses remain unclear. By quantifying the behavior of live cells with phase contrast and fluorescence microscopy, the dynamic regulation of TN-C promoter activity is examined. We employ an NIH 3T3 cell line stably transfected with the TN-C promoter ligated to the gene sequence for destabilized green fluorescent protein (GFP). Fully automated image analysis routines, validated by comparison with data derived from manual segmentation and tracking of single cells, are used to quantify changes in the cellular GFP in hundreds of individual cells throughout their cell cycle during live cell imaging experiments lasting 62 h. We find that individual cells vary substantially in their expression patterns over the cell cycle, but that on average TN-C promoter activity increases during the last 40% of the cell cycle. We also find that the increase in promoter activity is proportional to the activity earlier in the cell cycle. This work illustrates the application of live cell microscopy and automated image analysis of a promoter-driven GFP reporter cell line to identify subtle gene regulatory mechanisms that are difficult to uncover using population averaged measurements.

Abstract
The extracellular matrix molecule tenascin-C is highly expressed during embryonic development, tissue repair and in pathological situations such as chronic inflammation and cancer. Tenascin-C interacts with several other extracellular matrix molecules and cell-surface receptors, thus affecting tissue architecture, tissue resilience and cell responses. Tenascin-C modulates cell migration, proliferation and cellular signaling through induction of pro-inflammatory cytokines and oncogenic signaling molecules amongst other mechanisms. Given the causal role of inflammation in cancer progression, common mechanisms might be controlled by tenascin-C during both events. Drugs targeting the expression or function of tenascin-C or the tenascin-C protein itself are currently being developed and some drugs have already reached advanced clinical trials. This generates hope that increased knowledge about tenascin-C will further improve management of diseases with high tenascin-C expression such as chronic inflammation, heart failure, artheriosclerosis and cancer.

Abstract
Fibroblast differentiation into myofibroblast in transforming growth factor-beta1-exposed human lung fibroblasts and the immunolocalizations of alpha-smooth muscle actin, fibronectin, tenascin-C, and osteopontin in exposed cells were studied by conventional transmission electron microscopy and immunoelectron microscopy. Ultrastructural features of myofibroblasts were detected after exposure, e.g., alpha-smooth muscle actin positive bundles in the cytoplasm of cells and extracellular fibronectin-containing structures on the surface of the cell forming fibronexus structure, osteopontin adjacent to rough endoplastic reticulum and extracellular tenascin-C in the vicinity of the cell. The authors concluded that exposure to transforming growth factor-beta1 can differentiate lung fibroblasts into ultrastructurally typical myofibroblasts.

Abstract
The aim of this study was to investigate tenascin-C (TN) immunolabelling and labelling for endothelium by von Willebrand Factor (vWF) in melanocytic tumours of dogs as compared with normal tissues, to evaluate the TN distribution in these types of tumours and to investigate whether a relation could be established between TN and angiogenesis in different types of tumour. Samples of normal dog skin (n=8), benign skin melanocytomas (n=10), malignant oral melanomas (n=9) and malignant toe melanomas (n=5) were studied. The percentages of TN and vWF immunolabelling per total microscopical area were analysed by morphometric methods. In normal skin, TN was found at dermo-epidermal junctions, around hair follicles, in the smooth muscles of hair follicles, and in the walls of blood vessels. TN immunolabelling (distribution and intensity) in melanocytomas was comparable with that found in normal skin. In melanomas, TN expression was considerably increased, its intensity in toe melanomas being twice that observed in oral melanomas. The degree of TN immunolabelling was not related to the histological malignancy of the melanomas. In melanomas, TN was found in the connective tissue surrounding the tumour cell nests and in narrow stromal strands inside the tumour. Regions infiltrated with lymphocytes were devoid of TN. The presence of TN around capillaries in melanocytomas and melanomas was investigated by double-immunolabelling (for TN and vWF). The intensity of vWF and TN immunolabelling was higher in melanomas than in melanocytomas, and higher in toe melanomas than in oral melanomas; however, no clear relation between TN expression and immunolabelling for vWF was found.

Abstract
The aim of this study was to analyse relationship between changes of the stroma and expression of tenascin-C (TN-C) and laminin in prostate carcinoma. Tenascin-C immunostaining was increased, and laminin decreased in carcinomas compared with peritumoral tissue and benign prostate hyperplasia (P<0.05). Statistical analysis confirmed connection between stromal changes and TN-C expression in prostate carcinoma (P<0.05). Gleason pattern 3 carcinomas showed more pronounced stromal reaction and TN-C expression compared with Gleason pattern 4 carcinomas (P<0.05). The main cells in prostate cancer stroma are myofibroblasts that are also responsible for tenascin production. Degradation of laminin was not connected with myofibroblastic stromal changes.

Abstract
Tenascin-C is an adhesion modulatory extracellular matrix molecule that is highly expressed in the microenvironment of most solid tumors. High tenascin-C expression reduces the prognosis of disease-free survival in patients with some cancers. The possible role of tenascin-C in tumor initiation and progression is addressed with emphasis on underlying signaling mechanisms. How tenascin-C affects malignant transformation, uncontrolled proliferation, angiogenesis, metastasis and escape from tumor immunosurveillance is summarized. Finally, we discuss how the phenotypes of tenascin-C knock-out mice may help define the roles of tenascin-C in tumorigenesis and how this knowledge could be applied to cancer therapy.

Abstract
OBJECTIVE To measure the immunohistochemical expression of the extracellular matrix (ECM) components tenascin, fibronectin, collagen type IV and laminin in urothelial carcinomas, and to correlate their expression with clinicopathological features to clarify the prognostic value of these molecules and their role in tumour progression. MATERIALS AND METHODS Tumour specimens obtained during transurethral resection of bladder tumour (TURBT) from 103 patients (82 men and 2 1 women, mean age 66.7 years, range 27-89) were studied retrospectively. The expression of tenascin, fibronectin, collagen type IV and laminin was correlated with clinicopathological features (tumour grade and stage, multiplicity, simultaneous in situ component, the proliferative activity as estimated by the two proliferation associated indices, Ki-67 and proliferating cell nuclear antigen, the recurrence rate, and the progression of invading tumour). Specimens investigated for tenascin expression from patients with superficial bladder cancers were categorized into 28 treated by TURBT only and 53 who had TURBT followed by intravesical instillations of interferon. RESULTS Cytoplasmic tenascin expression was detected in tumour cells in 20% of specimens. Tenascin was expressed in the tumour stroma in 76% of specimens, and was positively correlated with tumour grade and stage. Stromal tenascin expression was positively correlated with proliferative activity, and with the expression of fibronectin and collagen type IV. Fibronectin was expressed in the tumour stroma in 89% of specimens and was positively correlated with tumour stage, proliferative activity, and expression of collagen type IV and laminin. Collagen type IV was expressed in 93% of specimens, and was positively correlated with tumour grade and stage. Laminin was expressed in 78% of specimens and had no significant correlation with the clinicopathological features. Patients treated with TURBT alone and who had low levels of tenascin had a longer tumour-free interval than those with high levels of tenascin. CONCLUSION Levels of tenascin might be valuable for predicting the risk of early recurrence. The expression of tenascin, fibronectin and collagen type IV seems to be correlated with more aggressive tumour behaviour. Furthermore, their interrelationships could indicate that they are involved in the remodelling of bladder cancer tissue, probably influencing tumour progression.

Abstract
The prominent expression of tenascin-C in the stroma of most solid tumors, first observed in the mid 1980s, implicates tenascin-C in tumorigenesis. This is also supported by in vitro experiments that demonstrate the capacity of tenascin-C to stimulate tumor growth by various mechanisms including promotion of proliferation, escaping immuno-surveillance and positively influencing angiogenesis. However, tumorigenesis in tenascin-C knock-out mice is not significantly different from that observed in control animals. Perhaps this is not unexpected if one considers that tenascin-C may act as an oncogene. The potential role of tenascin-C in tumorigenesis through its oncogenic action on cellular signaling will be discussed in this review, including how tenascin-C mediated tumor cell detachment might affect genome stability.

Abstract
Recently, extracellular matrix components have been shown to contain domains that can interact with and activate receptors with intrinsic tyrosine kinase activity. These receptor tyrosine kinases are strong mediators of the cell responses of proliferation, migration, differentiation, and dedifferentiation. However, an interesting question is raised as to why cells would present growth factor receptor ligands in such a manner, as the majority of growth factors are small, soluble, or only transiently tethered ligands. With the exception of the discoidin domain receptors that bind collagen, the other described domains interact with a receptor that binds ubiquitous soluble peptide growth factors, the epidermal growth factor receptor. Unlike traditional growth factors, these individual "matrikine" domains within tenascin-C, laminin, collagen, and decorin possess relatively low binding affinity (high nanomolar or micromolar) and are often presented in multiple valency. The presentation of ligands within the extracellular matrix in this fashion might allow for unique biochemical and physiological outcomes. This new class of "matrikine" ligand may be critical for wound healing, as the majority of known extracellular matrix components possessing matrikines play a strong role, or are presented uniquely, during skin repair. Tenascin-C expression, for instance, is uniquely regulated spatially and has been proposed to present pro-migratory tracks during skin repair through its epidermal growth factor-like repeats. The epidermal growth factor-like repeats of laminin-5 act as cryptic ligands revealed upon matrix metalloproteinase-2 degradation of the surrounding extracellular matrix. The deletion of the discoidin domain receptors 1 and 2 for collagen have negative consequences on the role of fibroblasts and epithelial cells for matrix metalloproteinase production, migration, proliferation, and extracellular matrix turnover. Finally, decorin can bind to, inhibit, and down-regulate epidermal growth factor receptor levels and signaling, suggesting a tonic role of the epidermal growth factor binding domain of decorin in the resolution of wound healing. We provide a model framework for further studies into this emerging class of signals.

Abstract
AIMS To investigate the expression and the prognostic role of glycoprotein Tenascin-C (Tn-C) in primary melanoma of the skin. METHODS AND RESULTS The immunohistochemical expression of Tn-C was studied in 98 primary melanomas and related to inflammation, invasion, and patient outcome. Patients were followed up for disease recurrence for 0.04-7.4 years (median 3.9) and for survival for 0.5 to 12.1 years (median 9.3). The expression of Tn-C was evaluated for each tumour invasion border; the stromal and intracytoplasmic Tn-C of the melanoma islets were also recorded. Tn-C is widely expressed in primary melanoma samples, the staining pattern varying from focal to diffuse in different parts of the tumour. No correlation existed between intensity of Tn-C staining and inflammation. No stromal Tn-C was detected at the upper dermal lateral border in 12 patients, nor at the deep, dermal or subcutaneous border in 14 patients. These patients showed better disease-free survival (DFS) than did those cases with focal or diffuse staining (P = 0.06, P = 0.05). Also, absence of intracytoplasmic Tn-C was a beneficial prognostic factor for DFS (P = 0.04). In multivariate analysis, tumour ulceration and intracytoplasmic Tn-C expression of melanoma cells were independent adverse prognostic factors for DFS. CONCLUSIONS In primary melanoma of the skin, absence of Tn-C in the stroma of invasion fronts and within tumour cells seems to be related to a more benign disease behaviour with a lower risk of developing metastases.

Abstract
Tenascin-C is an adhesion-modulatory extracellular matrix protein that is predominantly expressed during embryonic development, wound healing and in tumor stroma. Here we report that anchorage-dependent human, rat and mouse fibroblasts adhere poorly and fail to proliferate on pure tenascin-C. This was due to a significant reduction of cyclin-dependent kinase 2 (cdk2) activity, resulting from elevated expression and association of the cdk inhibitors (CKIs) p21Cip1 and p27Kip1. To analyse the effect of tenascin-C on fibronectin-mediated adhesion, cells were plated on a mixed fibronectin/tenascin-C substratum. Compared to fibronectin alone, cell spreading and adhesion signaling were compromised, as determined by delayed phosphorylation kinetics of focal adhesion kinase (FAK). Despite the presence of growth factors, these cells remained arrested in the G1 phase of the cell cycle. In contrast to cells plated on pure tenascin-C, cdk2 activity appeared to be inhibited independently of CKIs. Interestingly, overexpression of the transmembrane proteoglycan syndecan-4 restored cell spreading, adhesion signaling and DNA replication on the fibronectin/tenascin-C substratum. A similar rescue was observed using a recombinant peptide that spans the syndecan-4-binding site in fibronectin. This indicates that tenascin-C causes cell cycle arrest and cdk2 inactivation by interfering with fibronectin-syndecan-4 interactions. We therefore propose that syndecan-4 signaling plays a central role in the control of cellular proliferation of anchorage-dependent fibroblasts.

Abstract
AIMS Tenascin-C is an extracellular matrix glycoprotein known to have anti-adhesive characteristics and to be expressed in various human malignant neoplasms. We hypothesized that the expression of tenascin-C would be increased in human malignant pleural mesothelioma, and its accumulation associated with the prognosis of the patients with this disease. METHODS AND RESULTS Thirty-seven cases of mesothelioma were studied by immunohistochemically using a monoclonal antibody against tenascin-C, and with a semiquantitative scoring system for tenascin-C in different areas of the tumours. In 10 selected cases tenascin-C mRNA in-situ hybridization was also analysed. Since transforming growth factor-beta (TGF-beta) is known to induce both the synthesis of tenascin-C and the growth of mesotheliomas, an immunohistochemical analysis of TGF-beta 1, -beta 2 and -beta 3 was also performed. Normal pleura (n = 7) and metastatic pleural adenocarcinomas (n = 7) were used as controls. Tenascin-C protein was expressed in every histological subtype of malignant mesothelioma, being most prominent in the fibrotic stroma of a tumour, around tumour cells and at the invasive border, whereas tenascin-C mRNA was scarce in tumour cells. The patients with less immunohistochemical expression for tenascin-C tended to live longer (P = 0.028 by Fishers' exact probability test). All mesotheliomas showed positivity for at least one isoform of TGF-beta. CONCLUSIONS In conclusion, high expression of tenascin-C protein in malignant pleural mesotheliomas may play a role in its invasive growth, and might serve as a prognostic marker of the disease.

Abstract
We searched by a cDNA subtraction screen for differentially expressed transcripts in MCF-7 mammary carcinoma cells grown on tenascin-C versus fibronectin. On tenascin-C, cells had irregular shapes with many processes, whereas on fibronectin they were flat with a cobble stone-like appearance. We found elevated levels of 14-3-3 tau transcripts and protein in cells grown on tenascin-C. To investigate the consequences of an increased level of this phospho-serine/threonine-binding adaptor protein, we transfected MCF-7 cells with a construct encoding full-length 14-3-3 tau protein and selected clones with the highest expression levels. The morphology of these cells on tenascin-C was flat, resembling that of cells on fibronectin. This was reflected by a similar pattern of F-actin staining on either substratum. Furthermore, the growth rate on tenascin-C was increased compared with the parental cells. After transient transfection of HT1080 fibrosarcoma and T98G glioblastoma cells with 14-3-3 tau, only the 14-3-3 tau-expressing cells were able to adhere and survive on tenascin-C, whereas all cells adhered well on fibronectin. Therefore, we postulate that tenascin-C promotes the growth of tumor cells by causing an increase in the expression of 14-3-3 tau, which in turn has a positive effect on tumor cell adhesion and growth.

Abstract
The immunohistochemical expression of the extracellular matrix (ECM) components tenascin (TN), fibronectin (FN), collagen type IV (Coll) and laminin (LN), and their possible relationships were studied in a series of 134 operable breast cancer cases. Their expression was also compared with the expression of the proteolytic enzyme cathepsin D (CD), the adhesion molecule CD44 standard form (CD44s) and other known factors to clarify the prognostic value and role of these molecules in tumour progression and metastasis. TN expression in the tumour stroma was positively correlated with tumour grade and size, CD44s expression, tumour and stromal CD expression as well as with FN, laminin and Coll expression in the same areas. TN expression was inverse correlated with ER status. Its expression at the invasion front was only positively correlated with the lymph node status. Survival analysis showed an increased mortality risk associated with high levels of TN expression. In multivariate analysis, among the ECM proteins, only TN expression was independently correlated with patients' survival. FN expression was positively correlated with lymph node involvement, with the proliferation-associated index Ki-67 and stromal CD expression. Survival analysis showed an increased mortality risk associated with a high level of FN expression. Coll expression was positively correlated with the tumour size and LN expression. An inverse relationship of Coll expression with ER and PgR receptor status was also found. LN expression was positively correlated with tumour and stromal CD expression, with the proliferation-associated index Ki-67 and inversely with ER receptor status. The observed alterations in the expression of ECM proteins in breast cancer tissue and their correlations with the proteolytic enzyme CD and the adhesion molecule CD44s, suggest an involvement in cancer progression. In addition, overexpression of stromal TN and FN seems to have negative prognostic value in breast cancer patients.

Abstract
Tenascin-C (TNC) is an oligomeric glycoprotein of the extracellular matrix with several distinct isoforms variably expressed during embryogenesis, tumorogenesis, angiogenesis and wound healing. In the normal human adult, TNC is found in large concentrations in articular cartilage, suggesting tissue-specific function. The purpose of this study was to determine the specific in vitro TNC splicing patterns of articular chondrocytes and a human chondrosarcoma cell line. Cells were cultured in a three-dimensional bead system and TNC splice variant expression and distribution were examined with the use of Western blotting techniques, semi-quantitative reverse-transcription polymerase chain reaction and immunohistochemistry. At both the transcriptional and post-translational levels, the chondrocytes were found to express significantly higher levels of the smaller 220 kDa isoform (P < 0.01), which was predominantly incorporated into the matrix. The splicing pattern of the malignant cells was characterized by a higher proportion of the larger 320 kDa isoform which was extruded into the media. In vivo studies are necessary to verify the expression of the large TNC isoform in chondrosarcoma and the production and integration of the smaller isoform in normal chondroid matrix. In addition, elucidation of the biologic functions of the two major TNC isoforms may lead to the development of novel diagnostic and therapeutic approaches to chondrosarcoma.

Abstract
We previously found an abnormal deposition of an extracellular matrix glycoprotein, tenascin-C (TN-C), in human corneas with pseudophakic/aphakic bullous keratopathy (PBK/ABK). In this work, we studied cellular TN-C receptors in normal and PBK/ABK corneas. Cryostat sections of normal and PBK/ABK corneas were stained by immuno-fluorescence for TN-C receptors: alpha2, alpha8, alpha9, alphaVbeta3, beta1, and beta6 integrins, and annexin II. Beta6 integrin mRNA levels were assessed by semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) using beta2-microglobulin gene to normalize the samples. In PBK/ABK compared to normal corneas, relatively minor changes were observed for alpha2 and beta1 integrins, and for annexin II. Alpha8, alpha9, and beta6 subunits of TN-C receptors, alpha8beta1 alpha9beta1, and alphaVbeta6, respectively, were absent from normal central corneas but were found in the central epithelium of PBK/ABK corneas. Beta6 integrin showed the most significant accumulation. It correlated best with the expression of TN-C rather than with the expression of other alphaVbeta6 ligands, fibronectin, and vitronectin. RT-PCR analysis also showed elevated levels of beta6 mRNA in PBK/ABK compared to normal corneas. Therefore, accumulation of TN-C in PBK/ABK corneas was accompanied by an increased expression of its three binding integrins, especially alphaVbeta6 in the corneal epithelium. The interaction of tenascin-C with these integrins may contribute to the fibrotic process that occurs in PBK/ABK corneas.

Abstract
Tenascin-C is an extracellular matrix glycoprotein that is spatially expressed during organogenesis, in inflammatory and fibrotic disorders, and in neoplasms. The aim of this study was to analyze its expression in developing human lung tissues during pseudoglandular, canalicular, saccular, and alveolar periods corresponding to Weeks 12 to 40. Lung tissues were obtained at autopsy from 34 nonmalformed cases. An immunohistochemical analysis and a messenger RNA (mRNA) in situ hybridization method combined with light microscopy were used. The extent of tenascin-C immunoreactivity was scored as absent, low, moderate, or strong in and around different types of pulmonary cells. The immunohistochemical expression for tenascin-C was strong beneath the airway epithelium, especially at the sites of airway subdivision during Weeks 12 to 23, whereas its expression was moderate or weak underneath alveolar and bronchiolar epithelia between Weeks 24 and 40. The expression for tenascin-C was strong in the intima of veins, especially in the canalicular period, i.e., Weeks 17 to 28. A moderate or strong immunoreactivity for tenascin-C was also observed around chondrocytes in every case studied during all periods. The increased expression of tenascin-C mRNA was most often seen in the cells below the airway epithelium. Taken together, tenascin-C is expressed in human lung during all developmental periods, and its expression is especially strong below the airway epithelium at the sites of airway subdivision.

Abstract
Tenascin-C is an oligomeric glycoprotein of the extracellular matrix that has been found to have both adhesive and anti-adhesive properties for cells. Recent elucidation of the two major TNC splice variants (320 kDa and 220 kDa) has shed light on the possibility of varying functions of the molecule based on its splicing pattern. Tenascin-C is prominently expressed in embryogenesis and in pathologic conditions such as tumorogenesis and wound healing. Fibronectin is a prominent adhesive molecule of the extracellular matrix that is often co-localized with tenascin-C in these processes. We studied the chondrosarcoma cell line JJ012 with enzyme-linked immunoabsorbance assays, cell attachment assays and antibody-blocking assays to determine the adhesive/anti-adhesive properties of the two major tenascin-C splice variants with respect to fibronectin and their effect on chondrosarcoma cell attachment. We found that the small tenascin-C splice variant (220 kDa) binds to fibronectin, whereas the large tenascin-C splice variant (320 kDa) does not. In addition, the small tenascin-C splice variant was found to decrease adhesion for cells when bound to fibronectin, but contributed to adhesion when bound to plastic in fibronectin-coated wells. Antibody blocking experiments confirmed that both the small tenascin-C splice variant and fibronectin contribute to cell adhesion when bound to plastic. The large tenascin-C splice variant did not promote specific cell attachment. We hypothesize that the biologic activity of tenascin-C is dependent on the tissue-specific splicing pattern. The smaller tenascin-C isoform likely plays a structural and adhesive role, whereas the larger isoform, preferentially expressed in malignant tissue, likely plays a role in cell egress and metastasis.

Abstract
Loss of epithelial morphology and the acquisition of mesenchymal characteristics are typical for carcinoma cells in tumour progression. In human breast carcinomas, up-regulation of tenascin-C (TN-C) and vimentin (Vim) is frequently observed in cancer cells and correlates with increased malignancy. Thus, it is possible that TN-C is co-expressed with Vim, representing cancer cells that have undergone epithelial-mesenchymal transition (EMT). This study examined 128 breast carcinomas using immunohistochemical techniques to demonstrate that mammary cancer cells are a prominent source of both TN-C and Vim. Statistical analysis revealed a significant association between TN-C and Vim expression in cancer cells. TN-C expression also correlated positively with overexpression of c-erbB-2 oncoprotein and down-regulation of oestrogen receptors (ERs). Eleven human mammary cancer cell lines and two 'normal' cell lines were examined by western blotting and immunohistochemistry. Co-expression of TN-C and Vim was detected in the carcinosarcoma cell line HS 578T, SK-BR-3 (B), fibroblast-like MDA-MB-231 cells, and the myoepithelial cell line HBL 100. These findings suggest that TN-C and Vim, when co-expressed in mammary carcinoma cells, represent regulator genes likely to be involved in EMT during mammary carcinogenesis.

Abstract
Interactions between tumour cells and surrounding extracellular matrix (ECM) influence the growth of tumour cells and their ability to metastasise. It is thus interesting to compare ECM composition in tumours and healthy tissues. Using the recently described MeLiM miniature pig model of heritable cutaneous malignant melanoma, we studied the expression of two ECM glycoproteins, the tenascin-C (TN-C) and tenascin-X (TN-X), in normal skin and melanoma. Using semiquantitative RT-PCR, we observed a 3.6-fold mean increase of TN-C RNAs in melanoma compared to normal skin. Both stromal and tumour cells synthesise TN-C. On the contrary, TN-X RNAs decreased 30-fold on average in melanoma. This opposite regulation of TN-C and TN-X RNAs was confirmed at the protein level by indirect immunofluorescence. Whereas pig normal skin displayed a discrete TN-C signal at the dermo-epidermal junction, around blood vessels and hair bulbs, the swine tumour showed enhanced expression of TN-C in these areas and around stromal and tumour cells. In contrast, normal skin showed a strong TN-X staining at the dermo-epidermal junction and in the dermis, whereas this signal almost completely disappeared in the tumour. The results presented here describe a dramatic alteration of the ECM composition in swine malignant melanoma which might have a large influence on tumourigenesis or invasion and metastasis of melanoma cells.

Abstract
We have investigated re-epithelialization following induction of suction blisters in humans in intact blisters, open wounds, i.e. blister roofs removed immediately after blister induction, and calcipotriol-pretreated open wounds. Intact blisters simulate blister healing in bullous disease, while open wounds simulate re-epithelialization during wound healing. Re-epithelialization was clearly faster in open wounds than in intact blisters, and was not affected by calcipotriol pretreatment. Bullous pemphigoid antigen 2 (BP180), bullous pemphigoid antigen 1 (BP230), plectin/hemidesmosomal 1 protein (HD1), laminin 5, laminin alpha5, laminin beta1, type VII collagen, tenascin-C, beta4, alphavbeta5, alpha5 and alpha9 integrins were studied in intact blisters and open wounds by immunohistochemistry. Hemidesmosomal plaque proteins BP230 and plectin/HD1, which connect the keratin cytoskeleton to the hemidesmosome, appeared earlier at the leading edge in intact blisters than in open wounds. Band-like immunostaining in the basement membrane for laminin 5, alpha5 and beta1 chains was continuous in blister bases, but partially discontinuous in open wound bases. The other antigens studied showed similar expression in intact blisters and open wounds. BP180, BP230, plectin/HD1, beta4 integrin, laminin 5 and tenascin-C expression were further studied in calcipotriol-pretreated open wounds. Calcipotriol did not affect the expression of these antigens. The immunohistochemical results suggest that the keratin cytoskeleton is linked to the basal plasma membrane of migrating basal cells via BP230 and plectin/HD1 earlier in the more slowly re-epithelializing blisters than in open wounds. An intact laminin sheath may inhibit keratinocyte migration in intact blisters.

Abstract
OBJECTIVES To evaluate a new tenascin-C assay performed on the Bayer Immuno 1 system. DESIGN AND METHODS The precision was measured using three levels of serum pools. Linearity was tested by diluting patient serum samples containing high tenascin-C concentrations, and the minimal detectable concentration determined by repetitive analysis of the zero calibrator. Preliminary reference intervals were determined by testing serum samples from 220 healthy individuals. Biovariability was estimated in a cohort of 20 apparently healthy subjects over 18 days. The levels of tenascin-C in patients with different liver diseases was tested. RESULTS The detection limit was 2 ng/mL. At concentrations ranging from 325 to 1957 ng/mL the assay demonstrated within-run and between-run CVs ranging from 4% to 3.6% and 8.4% to 6.7%, respectively. Dilutions of sera were linear and parallel to the standard curve with recoveries ranging from 97% to 100%. The reference interval (central 95% interval) for tenascin-C in serum of healthy adults was 199-906 ng/mL. The variability study yielded an analytical variability, CV(A), of 1.8%; a within-subject variability, CV(I), of 11.7%; and a between-subject variability, CV(G), of 39.3%. Tenascin-C concentrations in sera of liver disease patients were significantly increased. CONCLUSIONS The novel assay provides a rapid and reliable procedure for the determination of tenascin-C levels in human sera.

Abstract
Tenascin-X has been studied in developing and adult rat eye and in foetal and adult human eyes, using immunohistochemistry and frozen sections. The data were compared with the distribution of tenascin-C. The immunoreactivity for tenascin-X was seen in a basement membrane-like feature in different structures of embryonic (E) day 16-17 rat eyes. Postnatal (P) day 2 and older rat eyes showed immunoreactivity for tenascin-X in different connective tissues. In the epithelial basement membrane zone of the cornea, immunostaining was positive in P5 eyes, negative in P10 and P15 eyes and again positive in P30 and adult eyes. In the 20-week-old human foetus, immunoreactivity for the tenascin was seen in the posterior parts of the conjunctival stroma adjacent to the sclera and in a basement membrane-like fashion in anterior conjunctiva. In the adult human eye, immunoreactivity for tenascin-X was seen in the anterior one-third stroma of cornea as thin fibrils, in the stroma of the limbus and conjunctiva, and in blood vessels. Immunostaining for tenascin-C was seen in the posterior aspect of the further cornea, and in mesenchyme adjacent to cornea in E1617 rat eyes. Corneal keratocytes and Descemet's membrane showed immunoreactivity for tenascin-C in P2-P15 rat eyes. Sclera and the junction of the cornea, and sclera expressed tenascin-C in P2 and older rat eyes. In human foetal eyes, immunostaining for tenascin-C was seen in the anterior parts of the corneal stroma, in the basement membrane zone and Bowman's membrane of the corneal epithelium, in the posterior one-fifth of the corneal stroma and the sclera starting from the junction of the cornea and sclera. In normal human adult eyes, immunostaining for tenascin-X was seen in the anterior one-third stroma of cornea, in the stroma of limbus and conjunctiva, and in blood vessels. The association of tenascin-X and basement membranes in early development evokes a question of its potential function in the development of the basement membrane. The results also suggest the association of tenascin-X with connective tissue development as well as the association of tenascin-C with the migration of keratocytes during the development of the corneal stroma.

Abstract
Tenascin-C (Tn-C) is an extracellular matrix glycoprotein that appears in areas of epithelial-mesenchymal interaction during fetal development and in neoplasia. The immunohistochemical expression of Tn-C and its relationship to histology, nuclear grade, microinvasion, oestrogen (ER) and progesterone receptors (PR), and to cell proliferation measured by Ki-67 expression were studied in 89 intraductal breast carcinomas (DCIS). Periductal Tn-C was noted in 87% and stromal Tn-C in 25% of the tumours. Stromal expression was associated with moderate to strong periductal expression and microinvasion. Periductal expression was associated with comedo-type, nuclear grade, microinvasion, Ki-67 expression, and lack of PR. The distribution of Tn-C was compared in DCIS and in the intraductal component from another series of small axillary node-negative invasive breast carcinomas (n = 44). Tn-C was present in the stroma of pure DCIS in 25% and in the intraductal component of the other series in 82%. Thus, stromal or moderate to strong periductal Tn-C expression in DCIS may relate to early invasion. DCIS with weak periductal or missing Tn-C expression may be a subgroup with benign behaviour.

Abstract
Recently we showed that human epidermal keratinocytes express the extracellular matrix protein tenascin-C (TN-C) during wound healing, but not in normal adult skin. To gain further insight into the regulation of epidermal TN-C expression, we tested the effect of various stimuli on TN-C expression by cultured keratinocytes. Our results indicate that IL-4 is a very strong inducer of TN-C protein and mRNA expression in normal keratinocytes. Furthermore, TNFalpha and IFNgamma moderately increased TN-C expression. No other cytokines and growth factors that we tested, including various factors that stimulate TN-C expression in mesenchymal cells, significantly affected TN-C secretion by cultured keratinocytes. The regulation of TN-C expression in keratinocytes is distinct from that of fibronectin, since IL-4 and IFNgamma did not affect fibronectin expression in our experiments, and TNFalpha only slightly increased fibronectin levels. To investigate the role of cellular stress response pathways that can be activated by TNFalpha in the regulation of TN-C expression, we tested the effect of different inhibitors and an activator of these intracellular signalling cascades. The results show that the p38 MAP-kinase pathway is not involved in TNFalpha-induced TN-C expression in cultured keratinocytes. Activation of the JNK/SAPK-1 pathway by the addition of sphingomyelinase resulted in a dose-dependent increase of TN-C expression. TN-C expression by squamous carcinoma cell lines was differentially affected by the cytokines that stimulated TN-C expression in normal keratinocytes: TNFalpha again increased TN-C secretion, but IL-4 and IFNgamma had little effect. We conclude that there are distinct regulation mechanisms for TN-C expression in normal keratinocytes, tumor-derived keratinocytes and mesenchymal cells. The observation that TN-C is abundant in inflamed skin is a strong indication that inflammatory cytokines such as IL-4, TNFalpha and IFNgamma could also be involved in the regulation of epidermal TN-C expression in vivo.
