In this study, we demonstrate that MEC dose-dependently induced apoptosis in human colon cancer cell lines (COLO 205 and HT 29 cells). Results of a DNA ladder assay revealed that DNA ladders appeared with MEC treatment in COLO 205 cells at dosage of >50 microM. In addition, the total cell number decreased dose-dependently after treatment with MEC in COLO 205 and HT 29 cells. Using flow cytometry, the percentage of COLO 205 cells arrested at G0/G1 phase increased dose-dependently. Analysis of changes in cell-cycle arrest-associated proteins with Western blotting showed that p53 and p21 were upregulated after treatment with MEC. The kinase activities of cyclin-dependent kinase 2 (CDK2) and CDK4 were suppressed in MEC-treated cells. As for apoptosis, MEC may induce upregulation of p53 and downregulation of Bcl-2, thus causing the release of cytochrome C from mitochondria and the translocation of apoptosis-inducing factor (AIF) to the nucleus. This resulted in the activation of caspase 3, 8, and 9. Our results provide the molecular basis of MEC-induced apoptosis and cell-cycle arrest in human colon cancer cells. ------>tmu_sno=None ------>sno=16273 ------>authors2=Yuan-Soon Ho ------>authors3=Jie-Jen Lee ------>authors4=Chien-Liang Liu ------>authors5=Tsen-Long Yang ------>authors6=Chih-Hsiung Wu ------>authors6_c=??? ------>authors=Jiunn-Chang Lin ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=??? ------>publish_area=0 ------>updateTitle=Induction of apoptosis and cell-cycle arrest in human colon cancer cells by meclizine. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no= ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2007 ------>submit_flag=None ------>publish_month=1 |
