  • Title: [An experimental study of anticancer agent sensitivity test in human gastric cancer cell lines by flow cytometry].
    Author: Katayanagi N.
    Journal: Nihon Geka Gakkai Zasshi; 1990 Jul; 91(7):827-36. PubMed ID: 2118987.
    Abstract:
    The purpose of this study is to assess the lethal and kinetic effects of CDDP, ADM, MMC and 5FU on human gastric cancer cell lines, MKN28, MKN45 and KATO III. The lethal effect was examined by growth inhibition test and colony forming test. The DNA content and DNA synthesis rate of individual cells were simultaneously measured by DNA/BrdU double staining method. In growth inhibition test, MKN45 was sensitive to CDDP, and all cell lines were sensitive to ADM, MMC and 5FU. On the other hand, in colony forming test, these cell lines were sensitive to all drugs. In the cell kinetics, CDDP, ADM and MMC yielded a significant increase of G2 phase fraction at 24, 48 and 72 hours, and caused a significant decrease of BrdU labeling index at 48 hours. The changes of G2 phase fraction and BrdU labeling index were correlated well to the lethal effect of CDDP, ADM and MMC. However, 5FU did not cause these changes to the cell lines employed in the cell kinetic study. Therefore, it was suggested that these results of the cell kinetics might be applied to anticancer agent sensitivity test by selecting adequate anticancer drugs.
