[영문] Breast cancer is the most frequent cancer among female cancers in advanced countries such as the U.S. or Europe, which has been the primary cause of death in U.S. women. Recently, relation between synthesis of fatty acid and breast cancer was studied as associated with fatness. Furthermore, as oncogenic antigen-519 known as a prognostic factor of breast cancer was founded to be fatty acid synthase (FAS or FASN) by Kuhajda et al. in 1994, studies on FAS, which is an indicator of breast cancer, were begun. The FAS, an enzyme existing in the cytoplasm, does not exist in the extra cellular fluid (ECF) under normal condition. However, it was reported that the breast cancer cell lines would specifically secret FAS as culture medium, and recently that FAS was abnormally detected at high levels in the blood of cancer cases including breast cancer; a high level of FAS in plasma was detected from 83% of breast cancer patients, 53% of prostate cancer patients, 90% of colon cancer patients, and 40% of ovarian cancer patients.In this study, to measure an amount of protein in human blood, FAS protein separated from the human cell line (SkBr-3) and the rat liver was purified, the protein was set at standard concentration, and FAS assay was set up with two-site sandwich ELISA (2s-ELISA), one of enzyme linked immunoassays. It was deemed that as antigen protein, rather FAS separated from the human cell line (SkBr-3) than that extracted from the mouse liver would be more useful as control. Therefore, when 2s-ELISA was attempted using both the polyclonal anti-FAS antibody made with FAS protein directly separated from non-recombined animal cell to detect only FAS protein in human blood and the monoclonal antibody attached with biotin, FAS protein in human blood was detected. Also, after an amount of FAS protein was measured in the culture medium of different cell lines from breast cancer cell lines, it was specifically detected at a high level in the SkBr-3, BT-474, and MCF-7 cell lines. Finally, when an amount of FAS was measured in the blood of healthy persons and patients with breast cancer, a more amount of FAS protein was detected in breast cancer patients, and regarding age, a more amount of FAS was detected in patients aged above 42 than those aged under 42.The author expects that correlation of significant changes with clinical information of breast cancer patients will be analyzed by further developing and improving the above mentioned experimental method.prohibitio
