In vitro effects of G418 and gentamicin on selenoprotein biosynthesis. (A) HepG2 cells were incubated for 48 h in FCS-free medium with supplemental selenite (100 nM), G418 or gentamicin. Western blot analysis indicates increased secreted SELENOP protein levels in response to selenite and G418 treatment. Intracellular protein levels of selenoenzymes GPX1 and GPX2 were marginally affected. (B) The effect of gentamicin was verified in a dose-dependent analysis. (C) The effects of G418 on SELENOP secretion were replicated in human Hep3B, and (D) murine Hepa1-6 hepatocytes.
