Jones, Stephen Meyuhas, Oded Overexpression of RagB<sup>GTP</sup> can derepress TOP mRNA translation in amino acid-starved cells, but not in cells deprived of oxygen. <p>(A) HEK293 cells were infected with lentiviral expression vectors encoding FLAG-RagB or FLAG-RagB<sup>GTP</sup>. 48 h post infection cells were subjected to selection by puromycin and 48 h later were either kept untreated (+), amino acid-starved for 8 h (−AA), amino acid starved during the last 3 h of 24 h serum starvation (–Ser/AA) or deprived of oxygen (−O<sub>2</sub>) for 16 h. Cells were harvested and their cytoplasmic proteins were subjected to Western blot analysis using the indicated antibodies.
