Cox-2 expression in K562 cells was stimulated by IL-1beta, a specific inducing agent of Cox-2 expression Cox-2 expression was downregulated at higher doses of celecoxib (80-160 microM) suggesting a Cox-2-dependent mechanism was involved in the drug's effects of growth inhibition and induction of apoptosis. In addition, a synergistic effect was observed when cells were exposed to low-dose celecoxib (40 microM) and hydroxyurea (10 mM) or a combination of celecoxib (40 microM) and imatinib (0.2 microM). These findings provide the basis for uncovering the mechanism of celecoxib's antitumor effects and developing a new therapeutic strategy for treating CML |
