The expression of matrix metalloproteinase 9 and cathepsin B in gastric carcinoma is associated with lymph node metastasis, but not with postoperative survival.

Abstract: Degradation components of basement membrane could be crucial for tumor invasion. A key role in this process has been assigned to cysteine proteases, i.e. cathepsins and matrix metalloproteinases. The purpose of this study was to investigate the relationship of the expression of MMP-9 and cathepsin B with tumor aggressiveness expressed by lymph node metastases and survival rates in gastric carcinoma patients. Slides of 5 μm-thick serial sections from 91 patients with primary gastric carcinoma were prepared and … Show more

“…For instance, in the analysis of gastric carcinomas, high expression of cathepsin B, but not MMP9, was a statistically significant parameter in the depth of tumor invasion. 64 Interestingly, there are some indications that success of therapeutic trials targeting MMP activity is linked to the lack of cathepsin B in the tumors. For example, inhibition of MMP activity in renal cell carcinoma, a type of cancer with exceptionally low levels of cathepsin B, 65 was one of the rare MMPI trials where the overall survival of the patients was significantly prolonged.…”

“…one thousand cells of each section were randomly selected and counted blindly. the positive percentage of counted cells was semi-quantitated according to a 2-tier scoring system: weakly positive, 1-40%; and strongly positive, 41-100% (16). the slides were photographed under a nikon eclipse te2000-s Inverted microscope (magnification, x200).…”

“…the correlation between sialic acids content and tumor metastatic potential has been reported in many tumors and has received much attention recently. It has been proven that aberrant expression of terminal sialic acids, and in particular α2,3-sialic acids are related to tumor adhesion and invasion (5,6). High levels of sialylation of cell surface glycoconjugates could significantly increase metastasis of colon carcinoma cells and human melanoma cells (7)(8)(9).…”

“…Finally, 11 studies (Sier et al, 1996;Zhang et al, 2003;Wang et al, 2005;Mrena et al, 2006;Zheng et al, 2006;De Mingo et al, 2007;Czyzewska et al, 2008;Chu et al, 2010;Peng et al, 2010;Renet al, 2010;Yang et al, 2010) were eligible for meta-analysis. The main features of the eligible studies for MMP-9 were summarized in Table 1.…”

“…Immunohistochemistry was the mostly common technique used to detect MMP-9 expression with formalinfixed, paraffin-embedded tissue specimens, in two trails (Sier C et al, 1996;De Mingo et al, 2007), authors used ELISA to assess MMP-9. Different antibodies were used to detect MMP-9 expression with immunohistochemistry: three ( (Mrena et al, 2006;Chu et al, 2010) used an anti-rabbit antibody, five (Zhang et al, 2003;Wang et al, 2005;Czyzewska et al, 2008;Peng et al, 2010;Ren et al, 2010) used a monoclonal antibody and two (Mrena et al, 2006;Chu et al, 2010) used an polyclonal antibody. In one trial (Yang et al, 2010), authors evaluated positive expression of MMP-9 mRNA with MMP-9 (MK 1540) nucleotide probe (Boster Biological Technology Limited Company, Wuhan, China) to analyze its prognostic value.…”
