Low-dose uranium enters the HepG2 cell nucleus rapidly and induces cell stress response

Passage of uranium through human cerebral microvascular endothelial cells: influence of time exposure in mono- and co-culture in vitro models

“…The duplicated or triplicated samples were diluted with 2% nitric acid. As previously described (Gueguen et al 2015), U was quantified by Inductively-Coupled Plasma Mass Spectrometry (ICP-MS) (ICP-MS, X series II, Thermo Electron, France) using a 7700X series (Agilent Technologies, Les Ulis, France), calibrated with a SPEX CertiPrep U standard solution (Jobin Yvon, Longjumeau, France). The results of the analysis were expressed as parts per trillion (1 ppt ¼ 1 ng.L À1 ).…”
