Objective:Microtubule damaging agents such as nocodazole have been used in the clinical cancer chemotherapy. However, the molecular mechanisms of apoptosis induction activity of these agents are still unclear. We previously demonstrated that nocodazole induced apoptosis in human leukemic HL-60 cells. In order to investigate the genes involved in this process, cDNA RDA was performed to identify up-regulated genes in the apoptosis process induced by nocodazole. Methods:Sixteen up-regulated genes were identified and confirmed to be differentially expressed, including ribosomal proteins, cytochrome b, Wilm’s tumor related protein QM gene, alpha-tubulin isoform 1, heterogeneous nuclear ribonucleoprotein C enzymes, follicular lymphoma variant translocation 1, Ribophorin Ⅰ, etc. Results:It was the first time for several genes reported to be related to apoptosis, including one functionally unkown gene, BING4. We also analyzed the expression of these genes in apoptosis induced by etoposide, and results showed 9 genes were also up-regulated, indicating they could be important genes involved in apoptosis. Conclusion:The study provides important clues to understand mechanism of apoptosis induced by nocodazole, and establishes foundation for further study.
