Abstract/OtherAbstract:
BACKGROUND/AIMS: Only limited patients with hepatoma benefit from chemotherapy without a clear explanation. We aimed to identify genes associated with chemosensitivity using transcriptional profiles. METHODOLOGY: In 8 hepatoma cells (HLE, HLF, Huh7, Hep3B, PLC/PRF/5, SK-Hep1, Huh6, and HepG2) transcriptional profiles were obtained using cDNA microarray including 2300 genes. Chemosensitivities to 8 anticancer drugs (nimustine, mitomycin C, cisplatin, carboplatin, doxorubicin, epirubicin, mitoxantrone, and 5-fluorouracil) were measured by obtaining 50% growth inhibitory concentrations (GI50) using MTT assay. Genes having drug-specific association with chemosensitivity were selected. RESULTS: Up-regulation of topoisomerase II beta was associated with chemo-resistance, the target of doxorubicin. Platinum-specific resistance was associated with superoxide dismutase 2 expression. Antigen peptide transporter 1 expression correlated with nimustine and mitoxantrone-specific susceptibility. These results were verified by semi-quantitative RT-PCR. Drug inactivators reported in non-liver cancers such as multidrug transporters and drug metabolizers showed less diversity of chemosensitivity in hepatoma cells. CONCLUSIONS: To evaluate these gene expressions may be useful to select anticancer drugs, and possibly to consider new therapeutic target to modify drug action.
