Abstract
Despite decades of research, pediatric central nervous system (CNS) tumors remain the most debilitating, difficult to treat, and deadliest cancers. Current therapies, including radiation, chemotherapy, and/or surgery, are unable to cure these diseases and are associated with serious adverse effects and long-term impairments. Immunotherapy using chimeric antigen receptor (CAR) T cells has the potential to elucidate therapeutic antitumor immune responses that improve survival without the devastating adverse effects associated with other therapies. Yet, despite the outstanding performance of CAR T cells against hematologic malignancies, they have shown little success targeting brain tumors. This lack of efficacy is due to a scarcity of targetable antigens, interactions with the immune microenvironment, and physical and biological barriers limiting the homing and trafficking of CAR T cells to brain tumors. In this review, we summarize experiences with CAR T-cell therapy for pediatric CNS tumors in preclinical and clinical settings and focus on the current roadblocks and novel strategies to potentially overcome those therapeutic challenges.

Abstract
To investigate the significance of lymph node micrometastasis in T1N0 early gastric cancer. Lymph node micrometastasis may be a key mechanism in the recurrent T1N0 EGC patients after surgical treatment. It's unknow whether it is safe to leave the lymph nodes with micrometastasis untreated after ESD. A total of 106 T1N0 EGC patients were enrolled in this study. Immunohistochemical technique with CAM5.2 was employed to detect lymph node micrometastasis, and Immunohistochemical with D2-40 was used to detect the lymphatic vessels. Prognostic significance of lymph node micrometastasis and the relationship of lymph nodes micrometastasis with Clinicopathological features were analyzed. Twenty-two of the 106 T1N0 EGC cases were detected with lymph nodes micrometastasis, with the detection rate of 20.8%. The median survival time of the group with positive lymph nodes micrometastasis was lower than that of the group with negative micrometastasis, 48 vs 60 months. The incidence of lymph nodes micrometastasis in submucosal T1N0 EGC was 23.9%, while no micrometastasis was found in the mucosal T1N0 EGC. Of all the 30 cases according with the expanded ESD indications, six patients were found with lymph nodes micrometastasis. The occurrence of lymph node micrometastasis was common in T1N0 EGC. The cases with positive lymph nodes micrometastasis showed a lower median survival time than those with negative micrometastasis. lymph nodes micrometastasis incidence was higher in the submucosal ECG than in the mucosal ECG. lymph nodes micrometastasis was also found in the cases according to the expanded ESD indications.

Abstract
Tenascin-C is a large, multimodular, extracellular matrix glycoprotein that exhibits a very restricted pattern of expression but an enormously diverse range of functions. Here, we discuss the importance of deciphering the expression pattern of, and effects mediated by, different forms of this molecule in order to fully understand tenascin-C biology. We focus on both post transcriptional and post translational events such as splicing, glycosylation, assembly into a 3D matrix and proteolytic cleavage, highlighting how these modifications are key to defining tenascin-C function.

Abstract
Oral leukoplakia is a morphological alteration of tissue that is an early indicator for malignancy. Tenascin (TN) is a large hexameric extracellular matrix (ECM) protein with anti-adhesive properties that fosters cell migration during development, wound healing and tissue remodeling; it is present in small amounts in adult tissues. Overexpression of TN in a pathological condition may be either a cause or a consequence of the disease. We evaluated the efficacy of TN for early prediction of tobacco-associated oral cancers. We studied retrospectively 95 cases of oral leukoplakia, including mild, moderate and severe cases, using immunohistochemistry for TN. We evaluated the intensity, area and pattern of TN expression. Greater intensity and area of TN expression was observed in mild and severe dysplasia than in moderate dysplasia. Most cases showed a reticular pattern of expression, especially in mild and moderate dysplasia; a fibrillar pattern was more evident in severe dysplasia. We also observed homogeneous expression pattern in some cases. TN is a marker for dysplastic changes in epithelium and its expression may be helpful for predicting the malignancy potential of tobacco-associated oral leukoplakia.

Abstract
Metastasis is an inefficient process and most cancer cells fail to colonize secondary sites. There are several possible reasons for this. First, the nature of the infiltrating cells is important as a small population of cancer stem cells has been shown to have exclusive metastasis-initiating potential. Secondly, supportive niches are required to promote the outgrowth of disseminated tumour cells. Such niches are either produced prior to the arrival of cancer cells in the target organ or are induced ad hoc upon cell infiltration. Components of the extracellular matrix (ECM) have been found to play a role in establishing these niches. This has highlighted the importance of the ECM for metastatic progression, and suggests that such components may provide alternative targets for treatment of metastatic disease.

Abstract
To identify novel genes that could be involved in oncogenesis of oral squamous cell carcinoma a microarray-based gene-expression analysis was performed using tumour samples from patients with low-stage (n=4) and high-stage (n=4) disease in a pilot study. Genes (601) were found to be significantly regulated in cancer tissue compared to adjacent intraindividual mucosa controls. Genes (25) were identified with differences in their regulation comparing samples from early-stage cancer with those from advanced disease. The gene expression pattern of 5 of 7 genes examined by real-time-PCR verified the results received from the microarray-experiment. Among these, FMO2, CPA6, TNC and SIAT1 were significantly upregulated in early disease stages. LGI1 gene expression was significantly enhanced in normal adjacent mucosa of patients with early-stage disease without showing a differential expression in carcinoma biopsies. With this pilot study several novel genes were identified, which could be related to early and late stage disease. Hypotheses from these findings are discussed and have to be confirmed in a larger study sample.

Immunohistochemical assessment of fibronectin and tenascin and their integrin receptors alpha5beta1 and alpha9beta1 in gastric and colorectal cancers with lymph node and liver metastases.

Abstract
The aim of the current study was to assess immunohistochemically and compare the level of expression of tenascin (TN) and fibronectin (FN) and their integrin receptors alpha9beta1 and alpha5beta1 in the primary colorectal and gastric tumors, and in corresponding lymph node and liver metastases from 53 patients. We detected similar high deposition of the studied ECM proteins and their receptors in the stroma of primary tumors and in liver metastases and a lower deposition in lymph node metastases. Cytoplasmic immune reaction for FN and TN was also seen in the tumor cells. A pronounced co-localization of immune deposits for FN and TN and their receptors was found in the stroma of the center and the invasion front (IF) (p<0.0001). A significant decrease of FN immune signal was observed in the IF in primary tumors and liver metastases (p<0.0001). The levels of immunolabeling of FN and TN correlated with the differentiation grade of primary tumors (p<0.0001). In conclusion, we may say that there is heterogeneous deposition of TN, FN and their integrin receptors in the different areas of primary colorectal and gastric tumors and of their metastases. These findings imply that the studied proteins may be involved in cell processes such as growth, adhesion, migration and apoptosis.

Abstract
Expression of tenascin-C (Tn-C) has been shown to correlate with invasion and metastasis in Merkel cell carcinoma (MCC). Cytokeratin-20 (CK-20) is used in differential diagnostics of the primary tumour. The aim of this study was to demonstrate the expression of Tn-C in MCC lymph node metastases. Immunohistochemical staining was performed for five metastatic lymph nodes using a monoclonal antibody against Tn-C and CK-20. All five metastatic lymph nodes expressed Tn-C. The expression concentrated around the vascular structures, invasion borders and fibrotic septae. One of the metastatic lymph nodes was strongly positive for CK-20 while the others showed a focal or negative pattern. The normal lymphoid tissue was negative for Tn-C. Tn-C detected metastatic MCC tissue within the lymph nodes undisputedly. There was a clear distinction between the metastatic and normal lymphatic tissue. Furthermore, invasion to the surrounding tissue was easily demonstrated. Contrary to previous studies, CK-20 expression seemed to fluctuate.

Abstract
Tenascin-C (Tn-C) is a matricellular protein involved in the initial and intermediate stages of cell adhesion. The present study is the first undertaken to comparatively investigate Tn-C in neoplastic, non-neoplastic thyroid lesions and normal thyroid tissues. Forty-eight thyroid specimens were studied immunohistochemically using a monoclonal antibody against Tn-C. Immunohistochemistry was supplemented by RT-PCR analysis of the two Tn-C mRNA splice variants in 13 thyroid cancer cell lines. Normal and non-neoplastic tissues were devoid of Tn-C, as well as follicular neoplasms, Huerthle-cell and anaplastic carcinomas. Most papillary carcinomas showed a focally intensive extracellular staining, localized in the connective tissue stroma, whereas most medullary carcinomas showed a staining in the connective tissue but also in intracellular location mainly. RT-PCR analysis detected Tn-C mRNA in all thyroid cancer cell lines with prevalence of the large splice variant in all but the medullary line, characterized by a higher Tn-Csmall:Tn-Clarge ratio. In conclusion, Tn-C re-expression has been observed in papillary and medullary thyroid carcinomas with different staining patterns accompanied by the prevalence of different mRNA splice variants in cell cultures. It seems possible that Tn-C is rather synthesized by tumor cells than by activated stromal cells.

Abstract
The expression of tenascin, alpha-smooth muscle actin (alpha-SMA), desmin and vimentin was investigated immunohistochemically in the stroma of normal canine stomach, small intestine and colon, and in 30 epithelial tumours of the canine stomach, small intestine or colon. In addition, "co-localization" of tenascin and alpha-SMA was investigated by double immunohistochemistry. Tenascin was absent in the normal gastric mucosa but present in the normal intestine, with a gradual increase in immunolabelling intensity from the cryptal glands to the surface epithelium. Tenascin expression was greater in all adenomas and carcinomas than in normal tissues. Two different patterns of tenascin expression were observed in all carcinomas, irrespective of their site. In well-differentiated tumour regions of both gastric and intestinal tumours, a fibrillary sub-glandular expression was observed; in poorly differentiated tumour regions, however, the expression pattern was diffuse. Incomplete invasion of the muscularis mucosae was accompanied by thickening and increased tenascin expression. In normal stomach and intestines, alpha-SMA and desmin were demonstrated in pericryptal myofibroblasts and smooth muscle cells of the muscle layers. In colonic adenomas and gastric and intestinal carcinomas, alpha-SMA was demonstrated in all stromal cells surrounding tumour cells. In contrast to alpha-SMA labelling, desmin labelling was negative in tumour stromal cells (in both gastric and intestinal tumours), except in tumour regions close to the muscularis mucosae. This suggested that myofibroblasts in gastric and intestinal tumours originated from pre-existing fibroblasts, except in tumour regions close to the muscularis mucosae, where the myofibroblasts seemed to originate from smooth muscle cells of the muscularis mucosae. There was a strong co-localization of tenascin and alpha-SMA-expressing myofibroblasts, suggesting that myofibroblasts are responsible for tenascin secretion.

Abstract
To determine whether the content of the matrix protein tenascin-C (Tn-C) is of diagnostic or prognostic value in cervical lesions, we evaluated increases in Tn-C immunoreactivity in 80 formalin-fixed, paraffin-embedded biopsies and surgical specimens of the uterine cervix. Tn-C content in the basement membrane zone and in the stroma was graded and compared to some prognostic parameters. In the normal cervix, Tn-C formed a thin continuous band. In cervicitis, Tn-C bands thickened in the basement membrane zone and the adjacent stroma in the form of thin filaments. In 30 squamous intraepithelial lesions (SILs) of various grades, Tn-C bands were either slightly (1+) or moderately (2+) thickened in the basement membrane zone, while slight stromal Tn-C immunoreactivity in the form of thin bands was observed in 12 cases, regardless of grade and inflammatory stromal reaction. In invasive carcinoma, Tn-C content was markedly increased in the stroma and around the invasive nests of tumors. The intensity of Tn-C immunoreactivity was significantly higher in grade I tumors than in others (p < 0.04). The intensity of increase in Tn-C immunoreactivity was 10.5-fold (95% CI 3.39-32.5) higher in invasive cervical carcinomas than in others (cervicitis, low-grade SIL and high-grade SIL) (p = 0.0001). A significant correlation was found between weak Tn-C immunoreactivity and lymphatic space invasion (p = 0.001), lymph node metastasis (p = 0.01), desmoplastic stromal component (p = 0.0001) and stromal inflammation (p = 0.002). In conclusion, increase in Tn-C immunoreactivity may be of value in the assessment of noninvasive and invasive cervical lesions and the appearance of Tn-C may be an indicator of adequate biologic defense in cervical cancer patients.

Abstract
Tenascin (TN) is an extracellular matrix glycoprotein (ECM) that participates in embryogenesis and carcinogenesis. The aim of this study was to investigate immunohistochemically the expression of TN in the normal, hyperplastic, and neoplastic endometrium (endometrial adenocarcinoma). In the adenocarcinomas, the results were correlated with patient age, menopausal status, stage, grade, myometrial invasion, and vascular invasion. TN expression was studied in the following cases: proliferative endometrium (10 cases), early secretory endometrium (10), secretory endometrium (10), simple hyperplasia (15), complex hyperplasia (15), atypical hyperplasia (15), and endometrial adenocarcinomas (25). Staining of basal membranes and the cytoplasm of the stromal and epithelial cells was evaluated semiquantitatively. Positive staining was observed in the vascular and glandular basal membranes, stromal cells, and epithelial cells of proliferative, hyperplastic, and neoplastic endometrium. The difference in percentage of stained stromal cells between the neoplastic and the nonneoplastic (proliferative and hyperplastic) endometrium was significant (p<0.005). However, the percentage of stained epithelial cell area in hyperplasia was significantly higher than that of adenocarcinoma and functional endometrium (p<0.005). We conclude that TN is an extracellular matrix glycoprotein that plays a role in proliferation and possibly endometrial carcinogenesis.

Abstract
The expression of tenascin in colorectal tumours and liver was investigated in 30 patients with colorectal adenocarcinomas. Tissue samples were immersion-fixed in 4% paraformaldehyde solution. Free-floating cryostat sections were incubated with monoclonal antibody against tenascin, and examined by light and electron microscopy. Tenascin immunostaining was positive in sub-basement membrane zones and in newly-formed connective tissue of the primary tumour and perisinusoidally in the liver. The immunoreactivity in the sub-basement membrane zones of tumour glands in well- and moderately-differentiated tumours was more intensely expressed compared to that in poorly-differentiated tumours (p = 0.007 and p = 0.001 respectively, chi2-test). Perisinusoidal tenascin deposition was more often detected in the liver of patients with well-differentiated tumours (p = 0.006, chi2-test). The presence of metastases was accompanied by low tenascin deposition (p < 0.005, Fisher's exact test). Ultrastructurally tenascin deposits were observed around single tumour cells and glands in the primary tumours, and close to hepatic stellate cells in the liver. Finally, the role of tenascin deposition in the stimulation of tumour cell proliferation and mobility is discussed.

Abstract
OBJECTIVE Tenascin is an extracellular matrix glycoprotein, relevant for embryonal and fetal development, which is reexpressed in the stroma of benign and malignant tumors. Little is known about the molecular interaction of tenascin during neoplastic transformation and tumor progression in cervical cancer. METHOD We studied the expression of tenascin in normal tissue of the cervix uteri, cervical carcinoma in situ, and invasive cervical carcinoma in paraffin sections by immunohistochemistry using a monoclonal antibody. Tenascin immunoreactivity was compared with various prognostic parameters. RESULTS In normal cervical tissue (n = 5) and in cervical carcinoma in situ (n = 10) only vessel walls showed a weak tenascin cross-reactivity, whereas tenascin was not expressed in the epithelial layer or the underlying connective tissue. In invasive cervical carcinoma (n = 89) tenascin expression was markedly increased. In 84% (n = 75) of the cases examined a strong tenascin immunoreactivity was noted around and within the tumor cell nests. Sixteen percent (n = 14) of infiltrating cervical carcinomas showed no tenascin immunoreactivity. A definite correlation was found between weak or no tenascin expression and slight desmoplastic mesenchymal reactivity (n = 42/91%, P < 0.001), lymphatic space invasion (n = 54/81%, P < 0.001), and lymph node metastases (n = 30/77%, P < 0.05). Tenascin-positive patients had a significantly better prognosis than tenascin-negative patients (mean survival time of 56.5 +/- 4.1 months versus 31.9 +/- 5.6 months, P < 0.05). CONCLUSION Based on these findings we discuss that the appearance of tenascin is an indicator of an adequate biological defense in cervical cancer patients. The tenascin staining may therefore be useful for detecting a subgroup of invasive cancer patients missing tenascin reactivity with alterations of stromal defense and a poorer prognosis.

Abstract
A total of 169 colorectal adenocarcinomas, obtained from patients with a median follow-up of 6.5 years, were studied with immunohistochemical staining on cryosections using a monoclonal anti-tenascin antibody to evaluate the possible association between the staining patterns and tumour stage, tumour differentiation and survival. We found two different staining patterns in the tumour stroma--a diffuse stromal fibrillar staining in 92 out of 169 (54%) tumours and a subglandular staining in the remaining 77 tumours. When the entire group of patients (P < 0.01) and the group of potentially cured patients (P < 0.03) were analysed univariately, it was found that diffuse stromal fibrillar staining was associated with a shorter survival time than subglandular staining. In a multivariate analysis, the Dukes' stage and age were independent prognostic factors, whereas the tenascin expression did not retain a clear independent relationship to survival (P = 0.06). Hence, it appears that the tumour expression of tenascin may be a potential prognostic marker in colorectal cancer, in so far as a diffuse stromal fibrillar staining pattern seems to indicate an increased risk of poor outcome. However, after adjustment for age and Dukes' stage, the additional prognostic value of tenascin remains to be established in further analyses.

Abstract
The distribution of different laminin polypeptides, type VII collagen and tenascin has been studied in adult and foetal colorectal mucosa by using the indirect immunofluorescence technique. Immunoreactivity for laminin alpha 1 chain was located to basement membranes of epithelia, muscularis mucosae, and blood vessels, respectively in different segments of adult colon and rectum. Laminin beta 1 and gamma 1 chains were additionally expressed in lamina propria. Laminin alpha 2 chain was also found in lamina propria around the pericryptal fibroblasts. Immunoreactivity for laminin beta 2 chain was restricted to basement membranes in the muscularis mucosae and arteries. Laminin alpha 3 and beta 3 chains, suggestive for laminin-5, were confined especially to surface epithelial basement membranes. Immunoreactivity for type VII collagen was confined to basement membrane of surface epithelium in a punctate manner, while that for tenascin was seen slightly more broadly in the basement membrane zone and also in the muscular layer. The distribution of laminin chains in 16-week-foetal colon mostly resembled that of corresponding adult tissue, although immunoreactivities for laminin alpha 2 and beta 2 chains were lacking. Type VII collagen and the high molecular weight isoform of tenascin were also absent from the foetal colon. The results show that the basement membrane of the surface epithelium of colon and rectum express the components of epithelial adhesion complex, laminin-5 (alpha 3-beta 3-gamma 2) and type VII collagen, resembling in this respect small intestine and stomach while laminin-2 (alpha 2-beta 1-gamma 1) appears to be associated with pericryptal fibroblasts, and laminin-1 (alpha 1-beta 1-gamma 1) widely in most basement membranes.
