Abstract
Human papillomavirus (HPV)-associated lesions and malignancies exhibit alterations in the composition and functionality of the extracellular matrix (ECM) that represent the complex molecular pathways present between infection and disease. A total of 20 urine samples were used, including from 10 patients with cervical intraepithelial neoplasia grade 3 (CIN3) and 10 healthy controls to perform the label-free quantitative analysis using the nano-HPLC and ESI-MS ion trap mass analyzer and matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF/MS) fast screening. Among 476 identified/quantified proteins, 48 were significantly changed (log2-fold change ≥1.0 or ≤-1.0, -log10 (bbinominal, p-value ≥ 1.3), of which were 40 proteins (down-regulated) and 8 proteins (up-regulated) in CIN3, in comparison to healthy controls. The biological function and key pathway enrichment of the gene set using gen set enrichment analysis (GSEA) were analyzed. The ECM-receptor interaction pathway (NES = -1.64, p = 0.026) was down-regulated by 13 proteins (HSPG2, COL6A1, COL6A3, SPP1, THBS1, TNC, DAG1, FN1, COMP, GP6, VTN, SDC1, and CD44; log2 FC range from -0.03 to -1.48) for the CIN3 group in the KEGG database. The MALDI-TOF/MS screening showed the difference of protein profiles between the control and CIN3 groups, i.e., using the scatter plot with a well-separated shape, as well as effectively distinguishing both groups (control and CIN3) using genetic algorithms (GA) with cross-validation (51.56%) and recognition capability (95.0%). Decreased levels of ECM-receptor interaction proteins may cause disturbances in the interactions of cells with the ECM and play an important role in the development and progression of cervical cancer.

Differential Impact of Membrane-Bound and Soluble Forms of the Prognostic Marker Syndecan-1 on the Invasiveness, Migration, Apoptosis, and Proliferation of Cervical Cancer Cells.

Abstract
Cervical cancer ranks fourth among the most commonly diagnosed malignant tumors in women worldwide. Previously published evidence suggested a possible connection between the expression of the membrane-bound heparan sulfate proteoglycan syndecan-1 (Sdc-1) and the development of cervical carcinoma. Sdc-1 serves as a matrix receptor and coreceptor for receptor tyrosine kinases and additional signaling pathways. It influences cell proliferation, adhesion, and migration and is seen as a modulator of the tumor microenvironment. Following proteolytic cleavage of its extracellular domain in a process called shedding, Sdc-1 can act as a paracrine effector. The loss of Sdc-1 expression is associated with low differentiation of cervical carcinoma and with an increased rate of lymph node metastases. Here, we analyzed the clinical impact of Sdc-1 expression by analysis of public gene expression datasets and studied the effect of an overexpression of Sdc-1 and its membrane-bound and soluble forms on the malignant properties of the human cervical carcinoma cell line HeLa through functional analysis. For this purpose, the HeLa cells were stably transfected with the control plasmid pcDNA3.1 and three different Sdc-1-DNA constructs,encoding wild-type, permanently membrane-bound, and constitutively soluble Sdc-1. In clinical specimens, Sdc-1 mRNA was more highly expressed in local tumor tissues than in normal and metastatic cervical cancer tissues. Moreover, high Sdc-1 expression correlated with a poor prognosis in Kaplan-Meier survival analysis, suggesting the important role of Sdc-1 in the progression of this type of cancer. In vitro, we found that the soluble, as well as the permanently membrane-bound forms of Sdc-1 modulated the proliferation and the cell cycle, while membrane-bound Sdc1 regulated HeLa cell apoptosis. The overexpression of Sdc-1 and its soluble form increased invasiveness. In vitro scratch/wound healing assay, showed reduced Sdc-1-dependent cell motility which was linked to the Rho-GTPase signaling pathway. In conclusion, in cervical cancer Sdc-1 modulates pathogenetically relevant processes, which depend on the membrane-association of Sdc-1.

Abstract
Inflammation is a hallmark in the human cervix remodelling. A possible candidate inducing the inflammatory driven ripening of the cervix is the matrix component heparan sulphate, which has been shown to be elevated in late pregnancy in the cervix and uterus. Heparin and a glycol-split low molecular weight heparin (gsHep) with low anticoagulant potency has been shown to enhance myometrial contraction and interleukin (IL)-8 production by cervical fibroblasts. The aim of this study was to investigate the mechanism by which heparin promotes cervical inflammation. Wild-type, Toll-like receptor 4 (TLR4), Myeloid differentiation primary response gene 88 (MyD88) and Interferon regulatory factor 3 (IRF3)-deficient mice were treated by deposition of gsHep into the vaginas of nonpregnant mice. To identify which cells that responded to the heparin fragments, a rhodamine fluorescent construct of gsHep was used, which initially did bind to the epithelial cells and were at later time points located in the sub-mucosa. The heparin fragments induced a strong local inflammatory response in wild-type mice shown by a rapid infiltration of neutrophils and to a lesser extent macrophages into the epithelium and the underlying extracellular matrix of the cervix. Further, a marked migration into the cervical and vaginal lumen was seen by both neutrophils and macrophages. The induced mucosal inflammation was strongly reduced in TLR4- and IRF3-deficient mice. In conclusion, our findings suggest that a TLR4/IRF3-mediated innate immune response in the cervical mucosa is induced by gsHep. This low anticoagulant heparin version, a novel TLR4 agonist, could contribute to human cervical ripening during the initiation of labour.

Abstract
Syndecan-1, is a transmembrane heparan/chondroitin sulfate proteoglycan necessary for cell-cell and cell-matrix interactions. Its decreased level on the cell surface correlates with poor prognosis in several tumor types. Aberrant stromal localization of syndecan-1 is also considered an unfavorable prognostic factor in various human malignancies. In the presented work the question was addressed if changes in syndecan-1 expression are related to the prognosis of cervical cancer. Immunohistochemistry for syndecan-1 extracellular domain was performed on surgical specimens of primary cervical cancer. To follow the communication between tumor cells and stromal fibroblasts, their mono-and co-cultures were studied, detecting the expression of syndecan-1, smooth muscle actin, vimentin, and desmin. Immunohistochemistry of tumorous specimens revealed that while cell surface syndecan-1 expression was reduced on cancer cells, it appeared on the surface of tumor-associated fibroblasts. Until year 7, the cohort with high cell surface syndecan-1 expression had significantly longer survival. No difference in the same time-period could be detected when stromal syndecan-1 expression was analyzed. In vitro analysis revealed, that tumor cells can induce syndecan-1 expression on fibroblast, and fibroblasts showed that fibroblast-like cells are built by two cell types: (a) syndecan-1 positive, cytokeratin negative real fibroblasts, and (b) syndecan-1 and cytokeratin positive epithelial-mesenchymal transformed tumor cells. Syndecan-1 on the surface of cancer cells appears to be a positive prognostic marker. Although syndecan-1 positive fibroblasts promote tumor cell proliferation in vitro, we failed to detect their cancer promoting effect in vivo.

Prevalence of Syndecan-1 (CD138) Expression in Different Kinds of Human Tumors and Normal Tissues. DISEASE MARKERS 2019; 2019:4928315.

Abstract
Syndecan-1 (CD138) is a transmembrane proteoglycan known to be expressed in various normal and malignant tissues. It is of interest because of a possible prognostic role of differential expression in tumors and its role as a target for indatuximab, a monoclonal antibody coupled with a cytotoxic agent. To comprehensively analyze CD138 in normal and neoplastic tissues, we used tissue microarrays (TMAs) for analyzing immunohistochemically detectable CD138 expression in 2,518 tissue samples from 85 different tumor entities and 76 different normal tissue types. The data showed that CD138 expression is abundant in tumors. At least an occasional weak CD138 immunostaining could be detected in 71 of 82 (87%) different tumor types, and 58 entities (71%) had at least one tumor with a strong positivity. In normal tissues, a particularly strong expression was found in normal squamous epithelium of various organs, goblet and columnar cells of the gastrointestinal tract, and in hepatocytes. The highly standardized analysis of most human cancer types resulted in a ranking order of tumors according to the frequency and levels of CD138 expression. CD138 immunostaining was highest in squamous cell carcinomas such as from the esophagus (100%), cervix uteri (79.5%), lung (85.7%), vagina (89.7%) or vulva (73.3%), and in invasive urothelial cancer (76.2%). In adenocarcinomas, CD138 was also high in lung (82.9%) and colorectal cancer (85.3%) but often lower in pancreas (73.3%), stomach (54.2% in intestinal type), or prostate carcinomas (16.3%). CD138 expression was usually low or absent in germ cell tumors, sarcomas, endocrine tumors including thyroid cancer, and neuroendocrine tumors. In summary, the preferential expression in squamous cell carcinomas of various sites makes these cancers prime targets for anti-CD138 treatments once these might become available. Abundant expression in many different normal tissues might pose obstacles to exploiting CD138 as a therapeutic target, however.

Abstract
Purpose: The present study evaluates chondroitin sulfate (CS) and heparan sulfate (HS) in the urine and hyaluronic acid (HA) in the plasma of patients with prostate cancer before and after treatment compared to a control group. Materials and Methods: Plasma samples were used for HA dosage and urine for quantification of CS and HS from forty-four cancer patients and fourteen controls. Clinical, laboratory and radiological information were correlated with glycosaminoglycan quantification by statistical analysis. Results: Serum HA was significantly increased in cancer patients (39.68 ± 30.00 ng/ mL) compared to control group (15.04 ± 7.11 ng/mL; p=0.004) and was further increased in high-risk prostate cancer patients when compared to lower risk patients (p = 0.0214). Also, surgically treated individuals had a significant decrease in seric levels of heparan sulfate after surgical treatment, 31.05 ± 21.01 μg/mL (before surgery) and 23.14 ± 11.1 μg/mL (after surgery; p=0.029). There was no difference in the urinary CS and HS between prostate cancer patients and control group. Urinary CS in cancer patients was 27.32 ± 25.99 μg/mg creatinine while in the men unaffected by cancer it was 31.37 ± 28.37 μg/mg creatinine (p=0.4768). Urinary HS was 39.58 ± 32.81 μg/ mg creatinine and 35.29 ± 28.11 μg/mg creatinine, respectively, in cancer patients and control group (p=0.6252). Conclusions: Serum HA may be a useful biomarker for the diagnosis and prognosis of prostate cancer. However, urinary CS and HS did not altered in the present evaluation. Further studies are necessary to confirm these preliminary findings.

Abstract
Heparan sulfate (HS) is a biopolymer consisting of variably sulfated repeating disaccharide units. The anticoagulant heparin is a highly sulfated intracellular variant of HS. HS has demonstrated roles in embryonic development, homeostasis, and human disease via non-covalent interactions with numerous cellular proteins, including growth factors and their receptors. HS can function as a co-receptor by enhancing receptor-complex formation. In other contexts, HS disrupts signaling complexes or serves as a ligand sink. The effects of HS on growth factor signaling are tightly regulated by the actions of sulfyltransferases, sulfatases, and heparanases. HS has important emerging roles in oncogenesis, and heparin derivatives represent potential therapeutic strategies for human cancers. Here we review recent insights into HS signaling in tumor proliferation, angiogenesis, metastasis, and differentiation. A cancer-specific understanding of HS signaling could uncover potential therapeutic targets in this highly actionable signaling network.

Abstract
Extracellular matrix (ECM) components form a dynamic network of key importance for cell function and properties. Key macromolecules in this interplay are syndecans (SDCs), a family of transmembrane heparan sulfate proteoglycans (HSPGs). Specifically, heparan sulfate (HS) chains with their different sulfation pattern have the ability to interact with growth factors and their receptors in tumor microenvironment, promoting the activation of different signaling cascades that regulate tumor cell behavior. The affinity of HS chains with ligands is altered during malignant conditions because of the modification of chain sequence/sulfation pattern. Furthermore, matrix degradation enzymes derived from the tumor itself or the tumor microenvironment, like heparanase and matrix metalloproteinases, ADAM as well as ADAMTS are involved in the cleavage of SDCs ectodomain at the HS and protein core level, respectively. Such released soluble SDCs "shed SDCs" in the ECM interact in an autocrine or paracrine manner with the tumor or/and stromal cells. Shed SDCs, upon binding to several matrix effectors, such as growth factors, chemokines, and cytokines, have the ability to act as competitive inhibitors for membrane proteoglycans, and modulate the inflammatory microenvironment of cancer cells. It is notable that SDCs and their soluble counterparts may affect either the behavior of cancer cells and/or their microenvironment during cancer progression. The importance of these molecules has been highlighted since HSPGs have been proposed as prognostic markers of solid tumors and hematopoietic malignancies. Going a step further down the line, the multi-actions of SDCs in many levels make them appealing as potential pharmacological targets, either by targeting directly the tumor or indirectly the adjacent stroma.

Abstract
OBJECTIVES Syndecan-1 expression is decreased in diverse tumor types but remains controversial in breast carcinomas. The goal of the study was to examine syndecan-1 expression in breast carcinoma and its prognostic significance. METHODS The epithelial expression of syndecan-1 was examined in tissue microarrays constructed from 62 consecutive breast carcinoma cases diagnosed between 1997 and 2004 with distant organ metastasis and 10 consecutive control cases (breast carcinoma with no distant metastasis after at least 8 years of follow-up). The prognostic significance of syndecan-1 was estimated by utilizing a Cox proportional hazards regression model. RESULTS Among tumors with distant metastasis, syndecan-1 expression was significantly associated with a higher histologic grade and inversely related to hormonal receptor status. The HER2 subtype and triple-negative carcinomas exhibited markedly higher syndecan-1 levels than those of luminal subtypes, while the latter remained significantly higher than nonmetastatic control cases. Furthermore, high syndecan-1 expression had a negative impact on both overall and disease-free survival rates. CONCLUSIONS These findings suggest that syndecan-1 may regulate breast cancer cell behavior and thus deserves further investigation to ascertain its potential as a therapeutic target, especially in metastatic, triple-negative carcinomas.

Abstract
Syndecans are transmembrane proteoglycans, with core proteins mainly decorated with heparan sulfate chains. Syndecan-1 is expressed in a tissue-, cell-and differentiation-specific manner. Its extra-cellular domain can bind via HS chains to matrix elements, to growth factors (especially "heparin-binding" proteins) and to certain biological agents. The ectodomain released by proteolysis can also be functionally active. The cytoplasmic domain can take part in signaling processes as well as in modifying cell shape. In hematopoietic cells syndecan-1 is expressed in normal pre-B-cells and plasma cells, as well as in plasmocytoid and lymphoplasmocytoid malignancies. According to our study syndecan-1 is expressed in B-CLL cells both in tissue environment and in circulation.

Abstract
Objective Syndecans are reported to have variable expression in several solid tumors and blood cancers. The cause provoking altered expression of syndecans is not known to date. We studied copy number status of syndecan-1 (SDC1) and significance of SDC1 gene product (syndecan-1, SDC1) expression in cervical cancers. Methods Using 121 cases of cervical cancer tissues, we screened SDC1 expression pattern using immunohistochemistry. We analyzed the relationship between SDC1 expression and clinicopathological parameters. To find possible causes of the expression change, we exploited interphase fluorescent in situ hybridization to screen copy number alteration of SDC1. Results Among 121 cases, 101 (83.5%) were positive and 20 (16.4%) were negative for SDC1. Among the parameters, age, histological type, and grade were significantly associated with SDC1 expression (p<0.05). Strong SDC1 expression in the cytoplasm showed better patient survival (p=0.02). In multivariate regression model, grade and SDC1 expression were independent prognostic factors (p<0.05). SDC1 in cervical cancers did not show copy number alteration. Conclusion Strong SDC1 expression in the cytoplasm of tumor cells predicts better patient survival. The change of SDC1 expression in cervical cancers is not caused by copy number alteration of the gene.

Abstract
Human epidemiological studies have shown that diets enriched in n-3 polyunsaturated fatty acids (n-3 PUFA) are associated with a lower incidence of cancers including breast cancer. Our previous studies showed that the n-3 PUFA, docosahexaenoic acid (DHA), upregulated syndecan-1 (SDC-1) expression to induce apoptosis in the human breast cancer cell line MCF-7. We now present evidence of a signaling pathway that is impacted by SDC-1 in these cells and in mouse mammary tissues to result in apoptosis. In MCF-7 cells and SK-BR-3 cells, DHA and a SDC-1 ectodomain impaired signaling of the p44/42 mitogen-activated protein kinase (MAPK) pathway by inhibiting the phosphorylation of MAPK/Erk (MEK)/extracellular signal-regulated kinase (Erk) and Bad to induce apoptosis. SDC-1 siRNA significantly enhanced phosphorylation of these signal molecules and blocked the inhibitory effects of DHA on their phosphorylation. SDC-1 siRNA diminished apoptosis of MCF-7 cells, an effect that was markedly blocked by MEK inhibitor, PD98059. In vivo studies used (i) Fat-1 mice, a genetic model able to convert n-6 to n-3 PUFA to result in higher SDC-1 levels in Fat-1 mammary tissue compared with that of wild-type (wt) mice. Phosphorylation of MEK, Erk and Bad was lower in the Fat-1 versus wt tissue and (ii) SDC-1(-/-) mice that demonstrated markedly higher levels of phosphorylated MEK, Erk and Bad in mammary gland tissue compared with those of SDC(+/+) mice. These data elucidate a pathway whereby SDC-1, upregulated by DHA, induces apoptosis in breast cancer cells through inhibition of MEK/Erk/Bad signaling.

Abstract
The syndecan family consists of four distinct membrane glycoproteins in mammals. Syndecans control cell proliferation, differentiation, adhesion and migration through participation in cell-cell interactions, anchorage of cells to the extracellular environment, and modulation of multiple growth factors. Therefore, syndecans may play a pivotal role in the regulation of cell behaviour depending on the cellular microenvironment. Here, we demonstrate that syndecan-1, syndecan-2 and syndecan-4 are expressed in fetal membrane tissue with different immunolocalizations. Syndecan-1 is expressed in the amniotic epithelium, localizing at basolateral cell surfaces. Syndecan-2 and syndecan-4, in contrast, are mostly localized in intracellular compartments, in the extravillous cytotrophoblastic cells and in some fibroblasts of the chorionic plate as well as in the amniotic epithelial cells. In the latter, syndecan-4 is mainly localized in the apical part of the cells. Our results strongly suggest a key role of syndecan-1, syndecan-2 and syndecan-4 in the determination of structural and functional characteristics of human amnion and chorionic plate. Since the solute exchanges between fetus and mother take place in fetal membranes, our data suggest that syndecans are important players in the placenta for the establishment of the fetalmaternal inter-communication.

Abstract
Heparanase is an endoglycosidase that specifically cleaves heparan sulfate side chains of heparan sulfate proteoglycans, the major proteoglycans in the extracellular matrix and cell surfaces. Traditionally, heparanase activity was implicated in cellular invasion associated with angiogenesis, inflammation, and cancer metastasis. More recently, heparanase up-regulation was documented in an increasing number of primary human tumors. Iotan this study, we sought to investigate the expression of heparanase messenger RNA (mRNA) in normal cervical tissue and intraepithelial cervical lesion and its clinicopathologic importance in invasive cervical cancer. Gene expression of heparanase was assessed by quantitative real-time reverse transcriptase polymerase chain reaction in 28 normal cervical, 26 intraepithelial neoplastic, and 48 cervical cancer tissue samples. Heparanase mRNA expression was different between the 3 groups and lower in normal cervical specimens in relationship with intraepithelial cervical lesions and invasive cervical cancer tissue samples (P = 0.048). Gradually increasing expression of heparanase was evident as the cells progressed from low-grade to high-grade squamous intraepithelial lesions (P = 0.002). In invasive cervical cancer cases, there was a direct correlation between heparanase expression and tumor size (P = 0.002). In cases treated with radical hysterectomy and pelvic lymphadenectomy, the heparanase mRNA expression was significantly higher in tumors exhibiting lymph vascular space invasion (P = 0.044) and in cases with big tumor size (P = 0.005). In our study, we did not find any significant correlation between disease-free and overall survival rates and expression of heparanase (P = 0.396 and P = 0.712, respectively). The results of this study suggest that the gene expression of heparanase in cervical cancer enhances growth, invasion, and angiogenesis of the tumor and may have therapeutic applications.

Abstract
The expression profile of a panel of RNA-binding proteins (heterogeneous ribonucleoprotein (hnRNP) A1, hnRNP C1/C2, hnRNP H, hnRNP I, ASF/SF2, SR proteins, HuR and U2AF(65)) and markers of differentiation, proliferation and neoplasia (cytokeratin (CK) 13, CK-14, proliferating cell nuclear antigen (PCNA), Syndecan-1 and p16INK4a) were analyzed in 50 formalin fixed paraffin embedded cervical tissues using immunohistochemistry. The samples included histologically normal cervical epithelium, human papillomavirus (HPV) induced low-grade and high-grade pre-malignant lesions and cervical cancers. All samples were tested for HPV DNA using nested PCR. Forty-nine of the 50 tissue samples tested positive for HPV, 27 tissue samples (54%) were HPV-16 positive and 4 samples (8%) were HPV-18 positive. The immunohistochemistry results detected different expression levels of the various proteins in basal epithelial cells in histologically normal epithelium followed by an increase in expression in the intermediate layers, whereas the superficial layers remained negative for all tested RNA-binding proteins. Expression of all RNA-binding proteins increased in neoplastic lesions and highest expression was detected in cervical cancers. p16INK4a had a stronger association with high-grade lesions when compared with the RNA-binding proteins. The expression profile of the RNA-binding proteins is similar to PCNA expression in histologically normal epithelium as well as in lesions (low-grade and high-grade) and cervical cancers. As PCNA expression has been suggested to mimic HPV E6/E7 expression in cervical epithelium, the results suggest the RNA-binding protein analyzed here regulate HPV early gene expression directly and late gene expression indirectly.

Abstract
Diets enriched in n-3 polyunsaturated fatty acids (n-3 PUFA) may protect against breast cancer but biochemical mechanisms are unclear. Our studies showed that the n-3 fatty acid docosahexaenoic acid (DHA) up-regulated syndecan-1 (SDC-1) in human breast cancer cells, and we tested the hypothesis that DHA-mediated up-regulation of SDC-1 induces apoptosis. DHA was delivered to MCF-7 cells by n-3 PUFA-enriched low-density lipoproteins (LDL) or by albumin in the presence or absence of SDC-1 small interfering RNA. The n-3 PUFA induced apoptosis, which was blocked by SDC-1 silencing. We also confirmed that SDC-1 up-regulation and apoptosis promotion by n-3 PUFA was mediated by peroxisome proliferator-activated receptor gamma (PPAR gamma). Using a luciferase gene driven by either a PPAR response element or a DR-1 site present in the SDC-1 promoter, reporter activities were enhanced by n-3 LDL, DHA, and PPAR gamma agonist, whereas activity of a luciferase gene placed downstream of a mutant DR-1 site was unresponsive. Cotransfection with dominant-negative PPAR gamma DNA eliminated the increase in luciferase activity. These data provide strong evidence that SDC-1 is a molecular target of n-3 PUFA in human breast cancer cells through activation of PPAR gamma and that n-3 PUFA-induced apoptosis is mediated by SDC-1. This provides a novel mechanism for the chemopreventive effects of n-3 PUFA in breast cancer.

Abstract
CD138/Syndecan-1 is a cell-surface heparan sulfate proteoglycan expressed on most epithelial cells, and decreased CD138 expression is associated with increased invasive and metastatic potential in carcinomas. CD138 expression has not been investigated previously in renal neoplasms. Formalin-fixed, paraffin-embedded tissue sections of 50 renal cell carcinomas (RCCs) (40 clear-cell RCCs of various nuclear grades, 10 of which harbored metastases; 6 papillary RCCs, 4 chromophobe RCCs) and 4 oncocytomas were stained immunohistochemically for CD138 using the monoclonal antibody B-B4 (CD138). Staining intensity and distribution were scored and results related to histologic type, nuclear grade, and local stage (pT). Immunoreactivity was membranous in all clear-cell RCCs, chromophobe RCCs, and oncocytomas and was located at the basal aspect of cytoplasm in papillary RCCs. In clear-cell RCCs, the extent of CD138 immunoreactivity decreased with increasing nuclear grade (P<0.001). No significant correlation was found between CD138 immunoreactivity and histologic type (P=0.2) or local stage (P=0.7). Metastatic foci showed a mild to moderate decrease in intensity compared with primary tumor. Decreased expression of CD138 may have a role in more aggressive behavior of clear-cell RCC.

Abstract
In vivo, bull sperm capacitation seems to occur mainly in the oviduct. Capacitation of bull spermatozoa can be triggered in vitro by exposure to heparin, a heavily sulphated glycosaminoglycan (S-GAG). We determined the concentration of S-GAGs in oviductal fluid from dairy heifers, collected over the course of several oestrous cycles via surgically implanted intraluminal catheters. We also investigated the presence of syndecans, i.e. heparan sulphate proteoglycans, in the bovine oviductal epithelium of Swedish dairy cattle during standing oestrus and the luteal phase of the oestrous cycle, using immunohistochemistry for three different polyclonal antibodies raised against human syndecan-2 and rat syndecan-1 and syndecan-2, respectively. The concentration of S-GAGs in oviductal fluid obtained from the ampullar segment of the oviduct was significantly higher (P=0.0026) than it was in fluid from the isthmic segment during the functional period, i.e. from prooestrus to metaoestrus (73.5+/-10.49 mg/L in ampullar ODF, compared to 43.2+/-10.74 mg/L in isthmic ODF); least square mean (L.S.M.)+/-standard error of the mean (S.E.M.). There was also a significantly higher concentration of S-GAGs in the fluid from the oviduct ipsilateral to the ovulation side 73.5+/-10.54 mg/L on the ovulation side, compared to 43.1+/-10.71 mg/L in the oviduct on the contralateral side (L.S.M.+/-S.E.M., P=0.0026) during this period. Both syndecan-1 and syndecan-2 were present in the epithelial cells lining all studied segments of the bovine oviduct, i.e. the UTJ, isthmus and ampulla, during both standing oestrus and dioestrus. The syndecans and S-GAGs found may influence the gametes, while they reside in the oviduct; the amounts of S-GAGs found in the bovine oviduct seem sufficient to act as capacitating factors in vivo.

Abstract
We examined expression of syndecan-1 in squamous cell carcinoma (SCC) of tongue using immunohistochemistry. Forty-three cases of SCC arising in lateral border of tongue were investigated. From the immunohistochemical staining pattern, the cases were divided into two groups based on expression of syndecan-1 at the supra-peripheral cells of the tumor nest: Group A, completely or mainly positive; Group B, sporadically positive or negative. Most poorly differentiated SCC cases were classified into Group B (81.8%). The number of Group B cases in T1-2 was different from that in T3-4. The number of cases where syndecan-1 expression was reduced was much greater in T3-4, and represented the majority of Group B (86.7%). More than 80% of Grade 4D cases were in Group B (83.3%) based on the Yamamoto-Kohama criteria. These results indicate that reduction of syndecan-1 correlates to histological grade, tumor size and mode of invasion in tongue SCC.

Abstract
Syndecan-1, a heparan sulfate-rich membrane glycoprotein, is expressed in plasma cells and is considered a reliable marker of plasmacytic differentiation. However, it has not been widely tested in non-hematolymphoid tissues, and thus its utility in the setting of an undifferentiated malignant neoplasm has not been evaluated. The authors conducted an extensive study of CD138 staining in over 1,700 normal, benign, and malignant non-hematolymphoid tissues, using five tissue microarrays. Immunohistochemical staining was performed with two commercially available CD138 monoclonal antibodies directed against syndecan-1 (Serotec, Oxford, UK, and DAKO, Carpenteria, CA). In addition to the specific membrane staining, many normal tissues and epithelial tumors showed strong cytoplasmic immunoreactivity. A small subset of mesenchymal neoplasms also showed membrane and cytoplasmic immunoreactivity. In squamous cell carcinoma of the head and neck, renal cell carcinoma, and prostate adenocarcinoma, the intensity of CD138 staining inversely correlated with the histologic grade of the carcinoma. However, statistically significant staining differences and their correlation with histologic grades differed depending on whether the Serotec or the DAKO antibody was used. These results indicate that CD138 immunoreactivity is widespread in normal and neoplastic epithelial tissues, as well as a variety of undifferentiated epithelial and mesenchymal processes. The authors conclude that the expression of syndecan-1, although relatively specific to plasma cells within the hematolymphoid system, should be interpreted with extreme caution in the setting of an undifferentiated neoplasm. Furthermore, the two commercially available monoclonal CD138 antibodies tested in this study showed significant differences in their immunoreactivity in different tumor types.

Abstract
Syndecan-1, a transmembrane proteoglycan, may exert anti-proliferative effects and promote cell growth by binding various growth factors. Malignant epithelial cells often down-regulate their own syndecan-1 production, and are capable of inducing an aberrant syndecan-1 expression in stromal fibroid cells. Decreased tumor cell syndecan-1 levels in human head and neck squamous cell carcinomas indicate poor prognosis, however, no correlation between stromal syndecan-1 expression and clinical parameters has previously been established. By means of immunohistochemistry, we observed a decrease in tumor cell syndecan-1 reactivity in 33/39 oral carcinoma cases, the degree of which, however, correlated only weakly with the clinical outcome (p = 0.097). Conversely, stromal syndecan-1 positivity proved to be a significant risk factor of recurrence (Cox analysis, p = 0.03) and tumor-specific death (p = 0.023) within a 24-month period after operation. Taken together, stromal expression of syndecan-1 is a reliable factor of adverse prognosis in oral carcinomas.

Abstract
Expression of syndecan-2, a transmembrane heparan sulfate proteoglycan, is crucial for the tumorigenic activity in colon carcinoma cells. However, despite the high-level expression of syndecan-2 in mesenchymal cells, few studies have addressed the function of syndecan-2 in sarcoma cells. In HT1080 fibrosarcoma cells, we found that syndecan-2 regulated migration, invasion into Matrigel, and anchorage-independent growth but not cell-extracellular matrix adhesion or proliferation, suggesting that syndecan-2 plays different functional roles in fibrosarcoma and colon carcinoma cells. Consistent with the increased cell migration/invasion of syndecan-2-overexpressing HT1080 cells, syndecan-2 overexpression increased phosphorylation and interaction of focal adhesion kinase (FAK) and phosphatidylinositol 3-kinase (PI3K), membrane localization of T-lymphoma invasion and metastasis gene-1 (Tiam-1), and activation of Rac. Syndecan-2-mediated cell migration/invasion of HT1080 cells was diminished when (a) cells were cotransfected with nonphosphorylatable mutant FAK Y397F or with other FAK mutants lacking PI3K interactions, (b) cells were treated with a specific PI3K inhibitor, or (c) levels of Tiam-1 were knocked down with small interfering RNAs. Furthermore, expression of several FAK mutants inhibited syndecan-2-mediated enhancement of anchorage-independent growth in HT1080 cells. Taken together, these data suggest that syndecan-2 regulates the tumorigenic activities of HT1080 fibrosarcoma cells and that FAK is a key regulator of syndecan-2-mediated tumorigenic activities.

Abstract
OBJECTIVES Loss of epithelial heparan sulfate proteoglycan syndecan-1 has been associated with a more aggressive behavior in various cancer forms, but the prognostic significance of syndecan-1 expression in colorectal cancer is unclear. The aim of this study was to evaluate the prognostic value of immunohistochemical syndecan-1 expression in a series of 237 patients with colorectal cancer. METHODS Paraffin-embedded formalin-fixed specimens were stained with a syndecan-1-specific monoclonal antibody, and both the epithelial and stromal expression were analyzed. RESULTS Epithelial expression of syndecan-1 was seen in 222 tumors (94%), and it was associated with low stage of disease (p = 0.002) and low histological differentiation grade (p = 0.048). The cumulative 5-year survival of patients with weak and strong syndecan-1 expression was 49 and 54 %, respectively (p = 0.234). Syndecan-1 stromal immunoreactivity was observed in 138 tumors (58%), but lacked prognostic significance. Staining pattern and distribution can be viewed from digitized representative microscope slides (virtual slides) at http://www.webmicroscope.net/supplements/syndecan. CONCLUSIONS The results are in line with previous reports in that low epithelial syndecan-1 expression was associated with a higher histological grade and a more advanced clinical stage of the patients. This study shows that syndecan-1 is expressed also in stromal tissue of colorectal cancer, but it does not support the proposed role of stromal syndecan-1 expression as a marker of poor clinical outcome.

Abstract
OBJECTIVE Syndecan-1 binds to various extracellular matrix components via its heparan sulfate glycosaminoglycans (HS-GAG) and most of its biological functions are considered to be associated with this process. The aims of this study are to investigate its expression in cervical neoplasms. METHODS We investigated the expression of both the syndecan-1 core protein and cell-surface HS-GAG by immunohistochemistry in 53 cervical intraepithelial neoplasm (CIN), 19 microinvasive, 143 invasive cervical cancers, and 29 metastatic lymph node samples, and analyzed correlations with various clinicopathological features. RESULTS The progression of CIN to early invasive cancer was found to associate with reduced levels of both syndecan-1 and HS-GAG expression. In squamous cell carcinomas, HS-GAG expression was significantly lower in cases with lymph-vascular space invasion. Additionally, the overall survival rates for patients exhibiting low HS-GAG expression was significantly lower than patients exhibiting high HS-GAG expression (P = 0.019). Low HS-GAG expression in positive nodes was determined to be a disease-free and overall survival prognostic factor (P = 0.028 and P = 0.018, respectively). CONCLUSION The loss of syndecan-1 and HS-GAG expression is an early event in cervical carcinogenesis. The loss of HS-GAG expression particularly in positive nodes can serve as an indicator of aggressive disease potential and poor prognosis in patients with invasive cervical cancer.

Abstract
Cell-cell and cell-extracellular matrix interaction is crucial in tumor progression. Tight junction (TJ) proteins as occludin and claudins (CLDNs) play important role in this process together with several extracellular matrix components, as syndecan. Our previous work suggested significant changes in the expression of claudins even in the early stages of cervical carcinogenesis. The aim of our present work was to study the expression of occludin and syndecan-1, as compared to CLDNs, in early phases of cervical carcinogenesis. Paraffin sections of 50 samples were studied by immunohistochemistry, including cervical intraepithelial neoplasias (CINI-II-III), in situ carcinomas (CIS) and normal cervical samples. Occludin and CLDN-2 were found colocalized in the basal layer, while syndecan-1 and CLDN-1, -4 and -7 were coexpressed in the parabasal and intermedier layers in normal epithelia. Intensity of occludin staining decreased in CIN/CIS lesions, although it was more extended towards the upper epithelial layers with inverse relation with grades, as seen in the case of CLDN-2 expression. CLDN-1, -2, -4 and -7 were detected in the entire epithelium in CIN, showing decrease in CIS. The progression of CIN was associated with reduced syndecan-1 expression, in contrast to CLDN-1, -4 and -7 which increased toward CIS. The obtained data suggest that significant changes occur in the composition of cell adhesion complexes even in early stages of cervical carcinogenesis. The pattern of expression is characteristic for the alteration, the changes in the different components, however, are not parallel with each other.

Abstract
Abstract
Context.—Chronic endometritis is reportedly observed in 3% to 10% of women undergoing endometrial biopsy for abnormal uterine bleeding. The diagnosis of chronic endometritis rests on the identification of the plasma cells. Their identification may be obscured by a mononuclear cell infiltrate, plasmacytoid stromal cells, abundant stromal mitoses, a pronounced predecidual reaction in late secretory endometrium, menstrual features, or secondary changes due to exogenous progesterone treatment prior to the biopsy. Syndecan-1 is a proteoglycan that is found on the cell surface of plasma cells and keratinocytes. Immunohistochemistry stains for this antibody may facilitate diagnosis of chronic endometritis.
Objective.—To determine whether or not routine syndecan-1 immunohistochemistry will aid in the diagnosis of chronic endometritis.
Design.—Immunohistochemistry stains for syndecan-1 were performed on 3 levels of 47 endometrial biopsies from patients with abnormal uterine bleeding. None of the patients had endometrial hyperplasia or an underlying malignancy. Clinical correlation and follow-up was attempted in 20 cases that showed evidence of plasma cells by syndecan-1 by immunohistochemistry.
Results.—Plasma cells were identified in 20 cases, 7 of which were initially diagnosed as chronic endometritis. The remaining 13 positive cases were diagnosed as tubal metaplasia (1), secretory endometrium (4), proliferative endometrium (4), menstrual endometrium (1), endometrial polyp (1), secretory endometrium with endometrial polyp (1), and endometrial polyp with exogenous hormone effect (1) based on the original hematoxylin-eosin section.
Conclusions.—Syndecan-1 may be a useful adjunct in the diagnosis of chronic endometritis. Approximately half of the cases of chronic endometritis responded to an antibiotic regime; thus, this diagnosis is important and may potentially obviate the need for surgical intervention.

Abstract
OBJECTIVES To determine the significance of syndecan-1 expression, a cell-surface heparan sulfate proteoglycan in localized and metastatic prostate cancer. METHODS We performed a retrospective analysis of 76 men with Gleason sum 6 or 7 prostate cancer treated by radical prostatectomy and a separate cohort of 75 men with metastatic prostate cancer. Syndecan-1 immunoreactivity was measured in primary prostate specimens or in samples from metastatic sites and correlated with patient outcome. RESULTS Syndecan-1 was expressed in normal basal and secretory epithelial cells, 26% of radical prostatectomy specimens, and 35% of metastatic disease. No association was found between syndecan-1 positivity and prostate-specific antigen recurrence in the collective cohort of Gleason sum 6 and 7 cancers. However, when stratified by Gleason sum, syndecan-1 immunoreactivity (immunoreactivity score 150 or greater) was associated with a greater recurrence rate in Gleason sum 7 cancers. Expression of syndecan-1 was significantly greater in soft tissue than in bone metastasis (P = 0.048, Fisher's exact test). CONCLUSIONS Consistent with a possible biochemical role for syndecan-1 in prostate cancer progression and metastasis, syndecan-1 expression correlated with serologic recurrence in Gleason sum 7 prostate cancer and was highly expressed in soft-tissue metastases.

Abstract
Anchorage of cells to "heparin"--binding domains that are prevalent in extracellular matrix (ECM) components is thought to occur primarily through the syndecans, a four-member family of transmembrane heparan sulfate proteoglycans that communicate environmental cues from the ECM to the cytoskeleton and the signaling apparatus of the cell. Known activities of the syndecans trace to their highly conserved cytoplasmic domains and to their heparan sulfate chains, which can serve to regulate the signaling of growth factors and morphogens. However, several emerging studies point to critical roles for the syndecans' extracellular protein domains in tumor cell behavior to include cell adhesion and invasion. Although the mechanisms of these activities remain largely unknown, one possibility involves "co-receptor" interactions with integrins that may regulate integrin function and the cell adhesion-signaling phenotype. Thus, alterations in syndecan expression, leading to either overexpression or loss of expression, both of which take place in tumor cells, may have dramatic effects on tumor cell invasion.

Abstract
BACKGROUND Leukoplakia is an oral pre-cancerous lesion that sometimes develops into squamous cell carcinoma. Therefore, leukoplakia with epithelial dysplasia is useful for studying carcinogenesis at the cellular level. The purpose of this study was to evaluate a potential association between the loss of syndecan-1 expression and the expression of p53 protein and Ki-67 antigen, and to identify reliable markers for predicting malignant changes in oral leukoplakia with epithelial dysplasia. METHODS Changes in the expression of syndecan-1, p53, and Ki-67 were examined immunohistochemically in 43 cases of oral leukoplakia with or without epithelial dysplasia. The subjects were categorized as: none, 13 cases; mild dysplasia, 5 cases; moderate dysplasia, 17 cases; and severe dysplasia, 8 cases. The expression of these molecules in normal oral epithelia (22 cases) was also investigated. RESULTS Strong syndecan-1 expression was observed on the surface of keratinocytes in normal epithelium. Immunopositivity was lost gradually as the extent of epithelial dysplasia increased. In normal epithelium, p53 and Ki-67 appeared mainly in the basal cell layer, while they were more widely distributed in leukoplakia. Specifically, significant changes were observed in the labeling index of p53 and Ki-67 in leukoplakia as epithelial dysplasia progressed from mild to moderate or severe. CONCLUSION Our results reveal that overexpression of p53 protein and Ki-67 antigen, and down-regulation of syndecan-1 expression in the lower part of the epithelium, are associated with dysplastic changes. Therefore, the down-regulation of syndecan-1 expression may be the most important reliable marker for dysplastic changes.

Abstract
BACKGROUND Endoglycosidic heparanase degrades heparan sulfate glycosaminoglycans, and may be important in cancer invasion and metastasis, although its expression in human cervical cancer has not been characterized. MATERIALS AND METHODS Heparanase association with clinicopathological features related to prognostic significance was examined in patients presenting with invasive cervical cancer. Gene expression of heparanase was assessed by RT-PCR in 10 normal cervix and 92 invasive cervical cancer samples. RESULTS Heparanase mRNA expression was not detected in any of the normal cervix specimens, but was significantly higher in advanced-stage tumors (P = 0.026). In cases treated with radical hysterectomy and pelvic lymphadenectomy, heparanase mRNA expression was significantly higher in tumors exhibiting lymph-vascular space invasion (P = 0.01). A significant relationship was found between microvessel counts and heparanase mRNA expression (P = 0.035). The disease-free and overall survival rates of patients exhibiting heparanase mRNA expression were significantly lower than those of patients lacking heparanase mRNA expression (P = 0.019 and 0.017, respectively). Furthermore, multivariate analysis showed that heparanase mRNA expression was an independent prognostic factor for both disease-free and overall survival. CONCLUSIONS These findings provide evidence that heparanase expression can serve as an indicator of aggressive potential and poor prognosis in cervical cancer. Consequently, heparanase inhibitor will be a novel candidate for therapeutic intervention in this disease.

Abstract
Keratoacanthoma (KA) resolves spontaneously but is regarded by some as a variant of squamous cell carcinoma (SCC). However, others consider KA a totally benign entity. Syndecan-1 is one of the heparan sulfate proteoglycans that mediates intercellular and cell to matrix adhesion. Its expression appears to be inversely correlated with tumor aggressiveness and invasiveness. Previous studies have shown decreased levels of syndecan-1 expression in invasive cutaneous SCC, correlating with tumor de-differentiation. However, a similar study has never been done on KA. To investigate syndecan-1 expression in classic KA and compare the results with those of classic invasive SCC, 24 KAs were immunostained for syndecan-1 (CD 138) using the monoclonal antibody B-B4 on formalin-fixed paraffin-embedded tissue. Results were semi-quantitatively scored as either negative or positive (mild, moderate, or strong) and compared with those previously obtained on 23 invasive SCC and in situ lesions. All 24 KAs were positive for syndecan-1 expression. Staining intensity of 18 cases was comparable with that of SCC in situ or adjacent normal epidermis. By comparison, invasive SCC showed significantly diminished staining. Reduced staining in focal areas of cytologic atypia at the base was present in three KAs. Syndecan-1 expression in KA mirrors that of SCC in situ and normal epidermis, providing a molecular basis that biologically KA may be closely related to SCC in situ but distinctively different from invasive SCC.

Abstract
Syndecan-1 is a transmembrane heparansulfate proteoglycan which regulates cell-to-cell or cell-to-extracellular matrix interactions and may influence malignant cell behavior. We investigated the alterations of syndecan-1 expressions in colorectal cancers and analyzed the relationship between histological and clinical characteristics. Syndecan-1 protein expression in colorectal cancer tissues was investigated with immunohistochemical staining of resected specimens. In situ hybridization was performed using syndecan-1 riboprobe to confirm the transcriptional signals. Syndecan-1 mRNA expression in cancer cell lines cultured with or without methylation inhibitor was also analyzed by quantitative PCR. Out of 105 specimens tested, less than 25% of tumor cells were stained with anti-syndecan-1 monoclonal antibody in 36 (34.3%). In situ hybridization showed a similar staining profile to that of immunohistochemistry. Syndecan-1 mRNA expression was increased by the methylation inhibitor 5-aza-2'-deoxycytidine, suggesting that the hypermethylation is involved in the suppression of syndecan-1 expression. Clinically, the incidence of metastasis to lymphnode or liver in patients with syndecan-1-negative tumors was significantly high. Among T1 colorectal cancers displaying a primary invasive phase, lymphnode metastasis, undifferentiated characters and 'budding' of cancer cells were more common in syndecan-1-negative tumors. The survival rate in patients with syndecan-1-negative tumors was decreased significantly in a stage-independent manner. These results suggest that the reduction of syndecan-1 expression in colorectal cancer cells, which is supposed to be regulated at the transcription level, is closely related to invasive character. The evaluation of syndecan-1 expression in colorectal cancer may allow prediction of patients' survival after surgery.

Abstract
Heparan sulfate proteoglycans play important biological roles in cell-cell and cell-matrix adhesion, and are closely associated with growth factor actions. Loss of syndecan-1, a cell surface-bound heparan sulfate proteoglycan, has been reported for advanced head and neck carcinomas, and expression of endoglycosidic heparanase, which cleaves heparan sulfate glycosaminoglycans (HS-GAGs), is associated with invasion and metastatic potential of malignant tumors. Paraffin sections of 103 primary esophageal squamous cell carcinomas were immunohistochemically examined for the expression of syndecan-1 core protein, HS-GAGs and heparanase protein, and the results were compared with various clinicopathological parameters, such as invasion depth. For 16 cases, fresh tumor samples were quantitatively analyzed for heparanase and syndecan-1 mRNA expression by real-time RT-PCR in addition to the immunohistochemical studies. Syndecan-1 core protein and HS-GAGs expression was significantly decreased in pT2 and pT3 cases compared with their pTis and pT1 counterparts. Decreased expression of core protein and HS-GAGs was correlated with the incidence of lymphatic invasion, and venous involvement. Furthermore, decreased expression of HS-GAGs was correlated positively with the incidence of nodal metastasis and distant organ metastasis, and negatively with the grade of tumor cell differentiation. The percentage of cytoplasmic heparanase protein-positive cases increased significantly in pT2 and pT3 cases compared to that in pTis and pT1 cases, and this was associated with lymphatic invasion, and venous and lymph nodal involvement. The level of heparanase mRNA was inversely correlated with the degree of HS-GAGs expression rather than core protein. In conclusion, loss of syndecan-1 and heparanase overexpression in esophageal squamous cell carcinomas are closely associated with malignant potential. Regarding the mechanism of loss of HS-GAGs, heparanase upregulation appears to play an important role.

Abstract
The failure of chemotherapy to cure a significant proportion of multiple myeloma (MM) patients and increasing knowledge of tumor immunology and MM biology have generated considerable interest in immunotherapy for this lethal disease. Immunotherapy for MM can be divided into three broad categories: passive antibody-mediated immunotherapy, active specific immunization (vaccination), and adoptive T-cell immunotherapy. Early clinical trials using anti-CD20 monoclonal antibodies (mAbs) have met with limited success so far but have also suggested that selected patient subgroups may benefit from this treatment. The availability of a truly tumor-specific antigen such as immunoglobulin idiotype, the recent demonstration that MM cells process and present idiotype to T lymphocytes, and formal evidence of an antitumor effect of idiotypic vaccination in follicular lymphoma provide the framework for applying idiotypic vaccination in MM. The ability to generate ex vivo functional dendritic cells has made it possible to fuse them with patients' MM cells, thus producing a different type of customized vaccine. Dendritic cells are also a pivotal reagent to generate ex vivo MM-specific cytotoxic T lymphocytes (CTLs) to be reinfused into the patient for adoptive immunotherapy. This review summarizes achievements in MM immunotherapy based on data reported since 1998.

Abstract
BACKGROUND Syndecan-1 and E-cadherin are cell adhesion molecules which are expressed primarily on the surface of adult epithelial cells. They appear to be co-regulated and may act in concert to stabilize the epithelium. Loss of expression of both E-cadherin and syndecan-1 is seen in malignant transformation and invasion. METHODS Thirteen cutaneous biopsies of acantholytic squamous cell carcinoma (SCC) were examined for coexpression of E-cadherin and syndecan-1. RESULTS Interestingly, immunoreactivity for E-cadherin was increased in the in situ component while immunoreactivity for syndecan-1 was similar to that seen in normal skin. Conversely, in invasive SCC the expression of these two adhesion molecules was very similar. Both diminished with decreasing cell differentiation, as well as in the acantholytic areas where both molecules exhibited increasing cytosolic staining rather than cell membrane staining. CONCLUSIONS Our results suggest that it is likely E-cadherin and syndecan-1 act in concert to stabilize the epithelium and that the loss or decreased expression of both of these adhesion molecules is associated with malignant transformation.

Abstract
OBJECTIVES The expression of syndecan-1, a cell surface heparan sulfate proteoglycan, is reduced during malignant transformation of squamous cells. Studies on squamous cell carcinoma of the head and neck have shown that syndecan-1-positive tumors are associated with longer overall and recurrence-free survival. The purpose of this study was to analyze syndecan-1 expression in invasive cervical carcinoma and to examine the association of syndecan-1 expression with prognostic factors and overall survival. METHODS The study population consisted of 124 patients treated for primary invasive carcinoma of the uterine cervix at the Turku University Central Hospital during the years 1970-1988. The material consisted of 102 (82.3%) squamous cell carcinomas, 16 (12.9%) adenocarcinomas and 1 (0.8%) adenosquamous carcinoma, 1 (0.8%) small cell carcinoma, 1 (0. 8%) adenoid basal carcinoma, 1 (0.8%) carcinosarcoma, and 2 (1.6%) unclassified cervical carcinomas. Syndecan-1 expression was determined on paraffin-embedded tissue blocks using a human syndecan-1-specific monoclonal antibody B-B4 and immunohistochemistry. The expression of syndecan-1 was classified according to staining intensity as well as the percentage of positively stained tumor cells. RESULTS Staining intensity was strong in 44 (36%) samples, while 24 (19%) specimens remained syndecan-1-negative. In 49 (40%) samples, the percentage of syndecan-1-positive cells was >/=90%. Syndecan-1 expression, as determined by >/=50% positively stained tumor cells, was associated with the grade of differentiation (P = 0.03) and squamous histology (P < 0.001), but was not associated with clinical stage (P = 0.16) or disease-free survival (P = 0.86). Age (P = 0.003) and clinical stage (P < 0.001) were significant prognostic factors, but syndecan-1 expression determined neither by percentage of positively stained tumor cells nor by staining intensity was associated with the outcome. CONCLUSIONS In cervical carcinoma syndecan-1 is associated with histological differentiation grade and squamous histology, but does not predict clinical outcome.

Abstract
Syndecans (syn-1, -2, -3, -4) and glypican-1 are proteoglycans expressed during development in association with changes in tissue organization and differentiation. They participate in the modulation of growth factor actions and in cell-cell and cell-matrix adhesion. The expression of syn-1, -2, -3, -4, and glypican-1 has been studied in normal human placenta and in gestational trophoblastic disease such as hydatidiform mole, invasive mole, and choriocarcinoma, using immunohistochemistry and western blots. Syndecan-3 was not expressed in normal or pathological tissues. During normal gestation, the other proteoglycans showed a specific staining pattern, which for some was modified during pregnancy. For instance, syn-1 was only expressed in syncytiotrophoblast; syn-4 was mainly localized in the villous and extravillous cytotrophoblast in the first trimester, whereas at term it was expressed in the syncytiotrophoblast. The most striking results are the altered expression patterns of syndecans and glypican-1 in pathological tissues. These proteoglycans showed a progressive decrease of immunostaining related to the increase of severity of trophoblastic disease, in particular in invasive mole and choriocarcinoma. In addition, dysregulation in the localization of the expression patterns was observed for syn-2 and -4. Because changes in syndecan expression enable cells to become more or less responsive to their micro-environment, the down-regulation and/or dysregulation of syndecans in relation to the degree of severity of trophoblastic diseases provides new insights into the progression of these pathologies.

Abstract
Syndecan-1 is a cell surface proteoglycan predominantly expressed on the surface of adult epithelial cells, and is normally present in all epidermal layers except for the most superficial terminally differentiated cells. Syndecan-1 mediates cell-cell and cell-extracellular matrix adhesion, thereby influencing cell morphology and growth characteristics. In addition, in vitro studies have shown that expression of syndecan-1 on tumor cells inhibits their invasion into the extracellular matrix. A total of 23 cutaneous biopsies of squamous cell carcinoma, including acantholytic squamous cell carcinoma, invasive squamous cell carcinoma which was not acantholytic, and squamous cell carcinoma in situ were examined for syndecan-1 immunoreactivity. The level of syndecan-1 expression was related to the degree of squamous cell dyshesion, with expression being greatest in the in situ lesions and least in the acantholytic lesions. The loss of syndecan-1 expression with increasing dyshesion of squamous cell carcinoma may be a mechanism for loosening of intercellular and cell-extracellular matrix attachments, thereby promoting the invasion of neoplastic cells into the dermis.

Abstract
Syndecan-1 is a transmembrane proteoglycan expressed predominantly in epithelial cells. Studies with immunohistochemistry have shown that syndecan-1 expression is reduced in carcinoma derived from human epidermis. Here we show that syndecan-1 mRNA, which is abundant in human primary keratinocyte (HK) and HaCaT spontaneous immortalized keratinocyte, is decreased in cervical-carcinoma cell lines. Further, in relation to a long and well-conserved 3' untranslated region (3' UTR) of syndecan-1 cDNA, we examined whether 3' UTR is involved with syndecan-1-mRNA reduction in cervical-carcinoma cells. A stable transfection experiment showed that addition of the 3' UTR does not affect expression in HaCaT, but that syndecan-1 cDNA containing the 3' UTR is not expressed efficiently selectively in cervical-carcinoma cell lines. The transient assay with CAT reporter plasmids linking the 3' UTR confirmed this, and indicated that the 3' end of the 3' UTR (nt 2285-2410) is required to influence expression in cervical-carcinoma cells. Further excessive expression of syndecan-1 suppressed growth in cervical-carcinoma cells. These results demonstrate that the reduction of syndecan-1 mRNA involved with the 3' untranslated region gives growth advantage to cervical-carcinoma cells.

Abstract
Syndecan-1, an important transmembrane heparan sulphate proteoglycan is expressed in distinct stages of differentiation of normal lymphoid cells: in pre-B cells and Ig-producing plasma cells; however, its normal function, or presence in lymphoid malignancies, is still largely unknown. The expression of syndecan-1 (CD138) was studied in 57 human non-Hodgkin lymphomas using immunocytochemistry and immunohistochemistry. Positive expression of syndecan-1 was found in the plasma cells in chronic lymphoblastic leukaemia (B-CLL) cases, in different plasmocytoid lymphomas as well as in myeloma. All normal and malignant Tcells, or CD5+ cells other than B-CLL proved to be negative. These results strongly suggest that syndecan-1 expression is a characteristic phenotypic marker for B-CLL and lymphoplasmocytoid lymphomas and could be used for diagnostic purposes.

Abstract
Syndecans comprise a gene family of transmembrane proteoglycans that regulate cellular behavior through interactions with various effectors, including heparin-binding growth factors and insoluble matrix components. Syndecan-1, the most extensively studied, localizes in epithelial cells and has been shown to present in normal hepatocytes. However, little is known about the change of syndecan-1 expression in human hepatocellular carcinoma (HCC). We investigated syndecan-1-protein expression by immunohistochemistry in 57 HCC tissue samples. Syndecan-1 gene expression was also determined. Syndecan-1 protein was expressed in cytoplasm and cell membrane of the hepatocytes and in the bile duct epithelial cells of liver with underlying hepatitis and cirrhosis. Conversely, among 57 HCC tissues, 39 HCC (68.4%) showed negative staining; 50% of well-differentiated HCC showed positive staining, whereas 82.4% of poorly differentiated HCC were negative. Loss of syndecan-1-protein expression was more prevalent in HCC with intra-hepatic metastasis (85.2%) than those without metastasis (48.0%). Similarly, syndecan-1 expression was significantly reduced in HCC with extra-hepatic metastasis (91.7%) as compared with the HCC without extra-hepatic metastasis (62.2%). The gene expression of syndecan-1 was significantly lower in HCC tissue than that in non-tumoral liver tissue. In 2 human HCC cell lines with poorly differentiated phenotype, HLE and HLF, syndecan-1 expression was markedly decreased both at the mRNA and the protein levels. These results suggest that the loss of syndecan-1 expression is a characteristic feature of HCC with high metastatic potential.

Abstract
E-cadherin is a Ca(2+)-dependent cell-cell adhesion molecule, which is mainly expressed in epithelial cells. Recent studies have shown that E-cadherin has an important role as an invasion suppressor molecule in epithelial tumor cells. Syndecan-1 is a cell surface proteoglycan that has been implicated in a number of cellular functions including cell-cell adhesion, cell-matrix anchorage and growth factor presentation for signalling receptors. Its suppression has also been shown to be associated with malignant transformation of epithelial cells. In order to better understand the coordinated regulation of cell-cell and cell-matrix interactions during malignant transformation, we have studied the expression of syndecan-1 in malignant mammary tumor cells genetically manipulated for E-cadherin expression. In invasive NM-e-ras-MAC1 cells, where E-cadherin was partially downregulated by specific antisense RNA, syndecan-1 expression was suppressed. Furthermore, transfection of E-cadherin cDNA into invasive NM-f-ras-TD cells resulted in the upregulation of syndecan-1 expression in association with decreased invasiveness. In both cases, regulation of syndecan-1 occurred post-transcriptionally, since syndecan-1 mRNA levels remained unchanged. Instead, a translational regulation is suggested, since syndecan-1 core protein synthesis was E-cadherin dependent. Another cell adhesion protein, beta 1-integrin was not affected by E-cadherin expression. The data provide an example of coordinated changes in the expression of two cell adhesion molecules, syndecan-1 and E-cadherin during epithelial cell transformation.
