EIF3F and infection: Quantitative analysis by densitometry showed that 6-, 2.58- and 0.82-fold more IL-8 was present in cells expressing the Flag-tagged eIF3f than that in cells without expressing the Flag-tagged eIF3f at 12, 16 and 24 hours post-infection, respectively (Fig. 6c, lanes 3–5 and 8–10).
