Research Abstract

We established two ovarian cancer cell lines which showed drug resistance for Paclitaxel/Cisplatin from their parental cell lines. The cDNA microarray analysis of these parental and resistant cell proposed eight candidate genes(ABCB1, ABCG2, IL6, IL8, DR5, p21, KISS1, MMP1) for the novel chemo-sensitivity test, which levels in resistant cell were significantly higher than in parental cell. The result of quantitative analysis of the eight genes in these ovarian cancer cell lines supported this consequence. Gaining informed consent, 13 ovarian cancer clinical samples and information were provided, which is available for database. The quantitative analysis of these eight genes in these 13 clinical samples revealed that the levels of resistant group were higher than sensitive group.
