Abstract:
The effect of taxol on the production of nitric oxide(NO) and reactive oxygen radicals(O2- and H2O2)and on the function of phagocytic activity of murine microglial cells were investigated. Stimulated cells also showed increased production such reactive oxygen radicals as surperoxide and hydrogen peroxide measured by luminometer after stimulated with phorbolmyristate acetate(PMA). Taxol alone had only being small effect on NO synthesis, whereas taxol in combination with rIFN-gamma synergistically increased NO synthesis in a dose dependent manner. The production of NO by taxol plus rIFN-gamma was reduced by such L-arginine analogues as N(G)-mono-metyl-L-arginine Monohydrate(N(G)MMA), and N-amino-L-arginine(NAA) and arginase which decomposes L-arginine. Collectively, the data illustrate the potential for taxol to activate microglia-mediated anticancer mechanisms in the brain in addition to its better characterized effects on ovarian, beast, and lung cancer.
