Background and purpose: Tumor vasculature is increasingly recognized as a target for cancer therapy. In recent years, a fusion protein consisting of the extra cellular domain of tissue factor (truncated tissue factor, tTF) was fused to the antibody selectively binding to tumor vasculature. Antibody-truncated tissue factor(Ab-tTF) fusion protein specifically induced thrombotic occlusion of tumor vessels resulting in tumor growth retardation or regression in some types of solid tumors. However, there were still some disadvantages in the above approach. We constructed and expressed that the (RGD)_3-tTF fusion protein with peptides arginine-glycine-aspartic acid (GRGDSP, abbr. RGD)as the carrier of tTF to explore whether it bad the capability of targeting to tumor vasculature in the colonic carcinoma model. Methods: The (RGD)_3-tTF fusion gene consisting of the tTF was fused to three series-wound peptides RGD. The (RGD)_3-tTF construct was expressed in Escherichia coil BL21(DE_3). The fusion protein was purified through Nickel affinity chromatography column. The activity of inducing blood coagulation was detected by clotting assay and coagulation factor X (FX) activation assay. The specific binding to integrins α_vβ_3 was analyzed by indirect enzyme linked immunosorbent assay (ELISA). All these were compared with the fusion protein RGD-tTE Colonic nude mice models were randomly divided into 3 groups (1 nude mice per group).Tumors were stained by the (RGD)_3-tTE RGD-tTF fusion protein and tTF which were labeled with Fluorescein Isothiocyanate(FITC). The location of the (RGD)_3-tTF fusion protein in the colonic carcinoma bearing nude mice tissue was analyzed by immunofluorescence assay. Results: The (RGD)_3-tTF fusion protein retained tissue factor thrombogenic activities. With increasing concentration, the clotting time was shortened correspondingly. Under the conditions of Ca~(2+), the clotting time was 9.96±0.56 min when the concentration was 6 μmol/L(P<0.01). The (RGD)_3-tTF fusion protein could activise F X above 6 μmol/L concentration, which was similar to RGD-tTF fusion (F=0.147, P>0.05). The ability of the (RGD)_3-tTF fusion protein binding specifically to integrins α_vβ_3 was stronger than that of the RGD-tTF fusion protein in the same concentration (F=164.81, P<0.01), which was apparently indicated by the A_(405nm) 1.25 and 0.95 when the concentration was 0.24 μmol/L. Immunofluorescence assay showed that the (RGD)_3-tTF fusion protein was assembling in the tumor vasculature of the colonic carcinoma bearing nude mice. Conclusion: The (RGD)_3-tTF fusion protein which retained tissue factor thrombogenic activities could bind specifically and efficiently to tumor vasculature in the colonic carcinoma bearing mice through binding to the tumor marker integrins α_vβ_3. It might be a promising foundation for further studies on the colon cancer molecular targeted therapy with tTF as an effective factor.

Background and purpose:Differentiation of tumor tissue is an important factor on determining the prognosis of gastric cancer. This study aimed to investigate the expression levels and clinical signiifcance of gender determining region Y-box 2 (SOX2) gene and octamer binding factor 4 (OCT4) gene in gastric cancer tissues varying different differentiation degrees. Methods: Sixty cases with gastric cancer were recruited in this study. The gastric cancer tissues and corresponding normal mucosa of the 60 cases were obtained. The mRNA and protein level of SOX2, OCT4 gene are evaluated by the quantitative real-time PCR (qRT-PCR), Western blot and immunohistochemistry, respectively. The relationship between the expression levels of SOX2, OCT4 gene and clinical pathological parameters were also analyzed in this study. Results:The expression of SOX2 in both mRNA and protein levels had no signiifcant difference between the well-differentiated gastric cancer tissues and normal gastric mucosa (mRNA levels:t=0.1033, P>0.05;protein levels:t=0.116, P>0.05). However, both the mRNA and protein expression of SOX2 in patients with well-differentiated gastric cancer tissues were signiifcant higher than not only in patients with moderately differentiated gastric carcinoma (mRNA levels: t=12.48, P<0.05; protein levels: t=22.78, P<0.05) but also in patients with than poorly differentiated gastric carcinoma (mRNA levels:t=17.56, P<0.05;protein levels:t=30.00, P<0.05). In contrast to SOX2, both the mRNA and protein expression of OCT4 in patients with well-differentiated gastric cancer tissues were signiifcant lower than not only in patients with moderately differentiated gastric carcinoma (mRNA levels:t=13.23, P<0.05; protein levels: t=25.56, P<0.05) but also in patients with poorly differentiated gastric carcinoma (mRNA levels: t=12.10, P<0.05; protein levels: t=69.48, P<0.05). There was no significance of OCT4 mRNA and protein expression between the well-differentiated gastric cancer tissues and normal gastric mucosa (mRNA levels:t=2.436, P>0.05;protein levels:t=1.064, P>0.05). Immunohistochemical study demonstrated that the positive rate of SOX2 in patients with well-differentiated gastric cancer tissues (10/21) were higher than in patients with not only moderately differentiated gastric carcinoma (7/20) but also poorly differentiated gastric carcinoma (2/19, P<0.05), while the positive rate of OCT4 in cases with well-differentiated gastric cancer tissues (2/21) were lower than in cases with not only moderately differentiated gastric carcinoma (6/20) but also the poorly differentiated gastric carcinoma (12/19, P<0.05). There was no correlation between the expression of SOX2, OCT4 in gastric cancer and gender or age (P>0.05). Nevertheless, the expression of SOX2, OCT4 were positive or negative correlated with the pathological staging, the degree of inifltration and lymph node metastasis (P<0.05). Conclusion:Decreased SOX2 expression and increased expression level of OCT4 can promote the formation, development and invasion of gastric cancer and they may become biomarkers or the diagnosis, treatment and prognosis evaluation in gastric carcinoma.
