The aim of this study was to identify biochemical alternations that would be the molecular targets applicable to mesothelioma imaging. For that purpose, we focused on the status of intracellular trace elements and measured the intracellular steady-state level of biologically important trace metals such as manganese (Mn), copper (Cu), zinc (Zn) in a human mesothelial cell line (MeT-5A) and in five human mesothelioma cell lines by inductively coupled plasma-mass spectrometry (ICP-MS). Furthermore, we determined the intracellular levels of manganese-superoxide dismutase (Mn-SOD) and copper/zinc-SOD (Cu/Zn-SOD). Interestingly, all mesothelioma cells highly expressed Mn-SOD compared with MeT-5A. The cells with increased Mn-SOD activity contained higher amounts of Mn, suggesting that intracellular Mn content is positively correlated with Mn-SOD., The Society for Molecular Imaging}, title = {Exploring molecular targets for mesothelioma imaging}, year = {2008} }
