“…SDC2 is a significant upstream regulator of the TGF-ß signaling pathway (6), regulating signaling by acting as a co-receptor for growth factors. SDC2 facilitates signaling by forming a ternary complex with TGF-ß and its signaling receptors, TGFRI and TGFRII (7)(8)(9).…”

Abstract. The transforming growth factor ß (TGF-ß) signaling pathway plays an important role in growth and development, and is critically involved in the genesis and development of tumors. Syndecan-2 (SDC2) and Cysteine-rich 61 (CYR61) are important genes in this pathway and SDC2 is known to be a significant upstream regulator of TGF-ß signaling. However, the roles of SDC2 and CYR61 in the development of esophageal squamous cell carcinoma (ESCC) remain unclear. In the present study, we investigated the relationship between SDC2 and CYR61 mRNA expression levels and disease prognosis in patients with ESCC. The mRNA expression of SDC2 and CYR61 was detected by quantitative real-time RT-PCR in 77 tissue specimens. Quantitative realtime RT-PCR showed that SDC2 and CYR61 mRNA expression levels were aberrant in ESCC tissue (P<0.01) and that SDC2 mRNA expression was significantly associated with tumor size (P=0.024) in ESCC. CYR61 mRNA expression was significantly associated with regional lymph node metastasis (P=0.034) and tumor size (P=0.03). A positive correlation between SDC2 and CYR61 (r=0.770; P<0.001) mRNA expression was observed. Moreover, we observed significant associations between altered expression of SDC2/CYR61 and regional lymph node metastasis (P=0.009) and TNM stages (P=0.033). Aberrant mRNA expression of CYR61 and SDC2/CYR61 (P=0.005 and P=0.026, respectively) were significantly associated with patient survival time. The multivariate Cox regression analysis showed that SDC2 and CYR61 were independent prognostic factors for survival. Our findings suggest that SDC2 may act as an a upstream regulator of the TGF-ß signaling pathway and regulate the expression of downstream target genes. Moreover, SDC2 and CYR61 expression affect the severity of cancer, and the survival of patients with ESCC. Importantly, we report that SDC2 and CYR61 are significant, independent prognostic factors for survival in ESCC. These findings may have implications for targeted therapies in patients with ESCC.

“…5,6 CYR61 is an important gene in the transforming growth factor-b (TGF-b) signalling pathway and it can be activated by thrombospondin-1 through its interaction with latent TGF-b binding proteins. This interaction results in activation of TGF-b so that it can bind to its receptors, thus stimulating the Smad pathway.…”

Objective: Cysteine-rich, angiogenic inducer, 61 (CYR61) is a key gene in the transforming growth factor-b signalling pathway, which is involved in the development of many tumour types. This study aimed to clarify the status and clinical significance of CYR61 expression in patients with ovarian epithelial carcinoma. Methods: Tissue from patients with ovarian epithelial carcinoma or benign ovarian tumours were investigated retrospectively for CYR61 expression at mRNA and protein levels, using reverse transcription-polymerase chain reaction and immunohistochemistry, respectively. Correlations between immunohistochemical scores and several clinicopathological parameters were investigated. Results: In 50 patients with ovarian epithelial carcinoma and 50 patients with benign ovarian tumours, CYR61 expression on mRNA and protein levels was significantly higher in ovarian epithelial carcinoma tissue than in benign ovarian tissue. CYR61 expression was associated with regional lymph node metastases and progression of clinical disease stage. There was no difference in CYR61 expression between patients aged <50 years and !50 years. Conclusions: CYR61 expression was significantly upregulated in ovarian carcinoma tissue compared with benign ovarian tumour tissue samples. Protein CYR61 levels were associated with lymph node metastases and Union for International Cancer Control stage. Protein CYR61 may be useful in targeted diagnosis and therapy, for patients with ovarian epithelial carcinoma.

The syndecans, heparan sulfate proteoglycans, are abundant molecules associated with the cell surface and extracellular matrix and consist of a protein core to which heparan sulfate chains are covalently attached. Each of the syndecan core proteins has a short cytoplasmic domain that binds cytosolic regulatory factors. The syndecans also contain highly conserved transmembrane domains and extracellular domains for which important activities are becoming known. These protein domains locate the syndecan on cell surface sites during development and tumor formation where they interact with other receptors to regulate signaling and cytoskeletal organization. The functions of cell surface heparan sulfate proteoglycan have been centered on the role of heparan sulfate chains, located on the outer side of the cell surface, in the binding of a wide array of ligands, including extracellular matrix proteins and soluble growth factors. More recently, the core proteins of the syndecan family transmembrane proteoglycans have also been shown to be involved in cell signaling through interaction with integrins and tyrosine kinase receptors.
