Figure 3.

Time dependent metabolic profiles of A549 cells after exposure to S. aureus. Volcano plots display the log₂ transformed fold change of intracellular metabolite amounts (normalized on 10⁷ cells) of infected versus control cells and the corresponding p-value (n = 3–9 out of at least three independent experiments). Metabolites with a p-value < 0.01 are coloured blue when FC_log2 > 1 and red when FC_log2 < −1. Significantly changed metabolites are displayed in word clouds in the corresponding colours and relative font size.
