  • Purpose: The purposes of this study were to compare and quantify the expression of Stromelysin-1 and MT-MMP-1 in the gingival tissues of patients with type 2 diabetes mellitus(DM) and healthy adults with chronic periodontitis. Materials and Methods: Gingival tissue samples were obtained during periodontal surgery or tooth extraction. According to the patient's systemic condition & clinical criteria of gingiva, each gingival sample was devided into three groups. Group 1 (n=8) is clinically healthy gingiva without bleeding and no evidence of bone resorption or periodontal pockets, obtained from systemically healthy 8 patients. Group 2 (n=8) is inflammed gingiva from patients with chronic periodontitis. Group 3 (n=8) is inflammed gingiva from patients with chronic periodontitis associated with type 2 DM. Tissue samples were prepared and analyzed by Western blotting. The quantification of Stromelysin-1 and MT-MMP-1 were performed using a densitometer and statistically analyzed by one-way ANOVA followed by Tukey test. Results: In the analysis of expression levels, Stromelysin-1 and MT-MMP-1 expressions were similar in group 1 and 2. Stromelysin-1 and MT-MMP-1 expressions was more increased in group 3 than group 1, 2. The difference between group 3 and group 1, 2 was statistically significant. Also, in the interrelationship of Stromelysin-1 and MT-MMP-1 expressions, expressions of Stromelysin-1 and MT-MMP-1 showed increasing tendency in chronic periodontitis associated with type 2 DM and it seems that the MT-MMP-1 expressions were increasing in proportion to Stromelysin-1 expressions. Conclusion: It is suggested that Stromelysin-1 and MT-MMP-1 may be partly involved in the progression of periodontal inflammation associated with type 2 DM, as related to a metabolism of other factors, such as AGE, plasmin and other inflammatory mediators. Therefore, the expression levels of Stromelysin-1 and MT-MMP-1 can be inflammatory markers of periodontal inflammed tissue with type 2 DM.

  • Background: Matrix metalloproteinases(MMP) are essential enzymes for tumor invasion and metastasis. Among the MMP family, elevated MMP-9 and stromelysin-3(STR-3) expression have been reported to be poor prognostic factors in lung cancer patients. To evaluate the possibility of a molecular diagnosis of lung cancer using peripheral blood, the mRNA expression level of MMP-9 and STR-3 was measured using a reverse transcriptase-polymerase chain reaction (RT-PCR) in patients with lung cancer. Methods : Ninety six patients(44 patients with lung cancer, 19 pulmonary infection, and 33 control) were included. To detect MMP-9 and STR-3 mRNA expression, RT-PCR was performed in peripheral blood mononuclear cells. ELISA was also used to measure the serum level of MMP-9. Results : MMP-9 was expressed more frequently in patients with a pulmonary infection(18/19, 94.7%) compared to lung cancer patients(26/44, 59.1%) or the controls (23/33, 69.7%) (p=0.018). On the other hand, STR-3 expression was observed more frequently in patients with lung cancer(37/44, 84.1%) compared to the lung infection patients(8/19, 42.1%) or control(20/33, 60.6%) (p=0.003). Among the lung cancer patients, MMP-9 was expressed more frequently when a tumor invaded the lymph nodes(17/24, 70.8%) compared to when a tumor did not(3/13, 23.1%) (p=0.005). The MMP-9 and STR-3 expression levels had no relationship with age, sex, tumor size, distant metastasis, or tumor histology. The serum MMP-9 concentration was not higher in lung cancer patients compared to patients with a pulmonary infection or the control subjects. Conclusion : STR-3 may be used as a diagnostic marker in the peripheral blood of lung cancer patients using RT-PCR. Further studies to evaluate the clinical significance of elevated STR-3 expression in lung cancer patients is recommended.

  • Objective: The purpose of this study was to evaluate on the antimicrobial effect on the periodontal pathogens and anti-inflammatory effect of Eriobotryae folium. Eriobotryae folium are constituent herbs of Gagamgamroum, which has been used for a long time in oriental medicine as a herbal medicine for treating halitosis and toothache. Method: Eriobotryae folium was prepared by extracting medicinal herb with water. We investigated antimicrobial activity by the minimum inhibitory concentration (MIC) test. We also investigated inhibition of $IL-1{\beta}-induced$ collagenase (mmp-1), stromelysin-1 (mmp-3), interleukin-6 gene expression in human gingival fibroblasts using RTPCR analysis. Result: The antimicrobial effects of Eriobotryae folium was evaluated with MIC against periodontopathogens; Porphyromonas gingivalis 2561, W50, A7A1-28, 9-14K-1, Prevotella intermedia 28, and Actinobacillus actinomycetemcomitans Y4. MICs of Eriobotryae folium were 1.25 mg/ml, 2.5 mg/ml, 0.625 mg/ml, 1.25 mg/ml, 10 mg/ml and 10 mg/ml. The anti-inflammatory effect of Eriobotryae folium was evaluated with influence of herbs on the $IL-1{\beta}-induced$ expression of mmp-1, mmp-3, and interleukin-6. $IL-1{\beta}$ increased mmp-1, mmp-3, and interleukin-6 mRNA levels. Eriobotryae folium significantly inhibited $IL-1{\beta}-induced$ mmp-1, mmp-3, and interleukin-6 gene expressions in a dose-dependent manner. Conclusion: These results suggested that Eriobotryae folium might reduce the excessive proteolytic capacity of the gingival fibroblast during inflammation and could be developed as a new drug for periodontitis.

  • Tissue inhibitor of metalloproteinases (TIMPs; TIMP-1, -2, -3 and -4) are endogenous inhibitor for matrix metalloproteinases (MMPs) that are responsible for remodeling the extracellular matrix (ECM) and involved in migration, invasion and metastasis of tumor cells. Unlike under normal conditions, the imbalance between MMPs and TIMPs is associated with various diseased states. Among TIMPs, TIMP-1, a 184-residue protein, is the only N-linked glycoprotein with glycosylation sites at N30 and N78. The structural analysis of the catalytic domain of human stromelysin-1 (MMP-3) and human TIMP-1 suggests new possibilities of the role of TIMP-1 glycan moieties as a tuner for the proteolytic activities by MMPs. Because the TIMP-1 glycosylation participate in the interaction, aberrant glycosylation of TIMP-1 presumably affects the interaction, thereby leading to pathogenic dysfunction in cancer cells. TIMP-1 has not only the cell proliferation activities but also anti-oncogenic properties. Cancer cells appear to utilize these bilateral aspects of TIMP-1 for cancer progression; an elevated TIMP-1 level exerts to cancer development via MMP-independent pathway during the early phase of tumor formation, whereas it is the aberrant glycosylation of TIMP-1 that overcome the high anti-proteolytic burden. The aberrant glycosylation of TIMP-1 can thus be used as staging and/or prognostic biomarker in colon cancer.

  • Background: Intraarticular local anesthetic injection has been therapeutically applied for pain control in various arthritis patients. However, little physiologic effects of local anesthetics on their tissue were known. This study was conducted to determine its effects on the cell proliferation and matrix metalloproteinases (MMP) production of cultured fibroblast like synoviocytes (FLS) derived from synovial tissues of rheumatoid arthritis patients. Methods: Bupivacaine with varying concentrations 0 (control), 0.1, 0.25, 0.5% was applied to experimental cell groups growing as monolayers in culture plates for varying durations 0 (control), 30, 90, 180 seconds in the presence and absence of interleukin-$1\beta$. Results: No statistical significances were noted in thymidine incorporation between 0, 30, 90 and 180 seconds exposure groups with 0.5% bupivacaine after 1 day and 2 days. Thymidine incorporation between 0, 0.1, 0.25, 0.5% exposure groups 1 day and 2 days after 90 seconds exposure did not show any differences. After exposure to bupivacaine, there were statistically significant increases in MMP-1 (p=0.025) and MMP-3 productions (p=0.000) of FLS in the absence of IL-$1\beta$, but no differences among the groups in the presence of IL-$1\beta$. Conclusion: We concluded that in this short-term in vitro study, bupivacaine does not have injurious effect on cultured rheumatoid arthritic joint tissues. The long-term effect cannot be known from this investigation.
