SGT 세포주에서 유로키나제형 플라스미노젠 활성제 및 제일형 플라스미노젠 활성억제제의 높은 발현

다국어 초록 (Multilingual Abstract)

Urokinase-type plasminogen activator (uPA) and plasminogen activator type 1 (PAI-1) inhibitor contribute to the invasiveness of many carcinomas. It will be helpful to study clinical behavior of patients with malignant tumor by analysis of their expression. Expression of uPA and PAI-1 in human salivary gland tumors has been rarely reported in vitro. The purpose of this study were to investigate the protein expression of uPA and PAI-1 in SGT cell line compared to oral SCC and HeLa cell lines and to study migration and adhesion assay. All the cell lines were cultured under DMEM with 10% FBS at at 37oC in a 5% CO2 incubator. We studied a possible association between cytosolic uPA and PA-1 concentrations in SGT cell line compared to any other cell lines through cell migration and adhesion assay, and enzyme-linked immunoassay(ELISA). In migration assay SGT cell line was about 2 .5-4 folds higher than another cell lines. In adhesion assay SGT cell line was about 1.1-2 folds higher than another cell lines. uPA cytosolic concentrations of SGT cell line was about 3-10 folds, while PAI-1 was about 2.5-10 folds. Oral SCC cell lines were the lowest value. Both uPA and PAI-1 concentrations were correlated with migration and adhesion assay. High cytosolic concentrations of uPA and PAI-1 was correlated with migration and adhesion assay. It suggested that these markers might be specific marker for SGT cell line and would be contributed to treatment and prognosis of human salivary gland adenocarcinoma
