Abstract
Nuclear microprobe analysis studies in cancer cell pharmacology and biology carried out at Bordeaux-Gradignan are reported. The cellular pharmacology of two anticancer agents, cis-diammine-dichloroplatinum(II), and 4′-iodo-4′-deoxy-doxorubicin, were investigated, as well as the role of iron in neuroblastoma carcinogenesis, and chromium(III) in trans-generation carcinogenesis. Nuclear microprobe analysis, using PIXE and particle backscattering microanalysis, was able to reveal intracellular and tissue distributions of the elements under investigation. Moreover, the fully quantitative and multi-elemental character of nuclear microprobe analysis offered information on possible mechanisms of drug action, metal carcinogenesis, and interactions with endogenous trace elements in cancer cells.
