TIA (T-cell intracellular antigens)-knockdown HeLa cells show an increase in ribosomes and translational machinery components. This increase correlates with specific changes in translationally up-regulated mRNAs involved in cell-cycle progression and DNA repair, as shown in polysomal profiling analysis. Our data support the hypothesis that a concerted activation of both global and selective translational rates leads to the transition to a more proliferative status in TIA-knockdown HeLa cells.
