Abstract: Objective To investigate the molecular mechanisms of Topoisomerase II inhibitor etopside(induced apoptosis on human leukemia HL-60 cells. Methods Cell growth and apoptosis were determined by MTT assay and flow cytometry.cDNA microarray was used to assess sensitive early gene expression profiles and Genmapp software was used to gene cluster and pathway analysis of the drug response. Results Etopside exhibited cell growth inhibition by 50 % at the concentrations of(30.17±0.26)mol/L and induced cell apoptosis from 4.38% to 53.96%.Genmapp analysis showed that etopside significantly inhibited ubiquitin-proteasome pathway(Z≥3.8) and decreased expression of genes involved in ubiquitin-proteasome pathway(PSMB5、PSMB7、PSMB8、PSMC3、PSMC5、RPN1and HLA(A). Conclusion Etoposide induces apoptosis via decreased expression of genes in ubiquitin-proteasome pathway.
