title: Influence of acetylsalicylic acid and metabolites on DU-145 prostatic cancer cell proliferation.
abstract: Conflicting reports have been published on the anti-tumour activities of acetylsalicylic acid in various cancers. Therefore, the effect of acetylsalicylic acid and its major metabolites has been studied on human prostatic carcinoma DU-145 cells. Investigations concentrated on the influence of acetylsalicylic acid, salicylic acid and salicyluric acid, on cell proliferation, DNA- and protein synthesis of DU-145 cells. DNA and protein synthesis determinations were done in vitro by [3H]thymidine and [3H]glycine incorporation, respectively. No effect on cell plating efficiency was observed, however proliferation studies showed that acetylsalicylic acid and salicylic acid inhibited cell growth (10 mM, 100% inhibition). No significant effect on cell proliferation was ascertained with salicyluric acid. Both DNA and protein synthesis were 40% inhibited by 0.1 mM acetylsalicylic acid. This study demonstrates that acetylsalicylic acid exhibits a significant influence on cell growth of prostatic DU-145 cells. These preliminary results may contribute to a better understanding of the anti-tumour capabilities of acetylsalicylic acid.
