GSEA analysis showed that the genes encoding for proteins belonging to the mitochondrial ribosomal translation and import machinery are enriched upon infection with Sp (MOI 10) alone and with CSE pre-exposure compared to the medium control (NES: 2.02 and 1.91, respectively) (Figure S6 and Figure 6b), implying that Sp has more distinct effect on mitochondrial gene expression than CSE. Here, TFF2 is linked to infection.
