Further investigation of genes involved in metabolism of lipids and lipoproteins revealed an activation of ASAH2, CROT, CYP1A1, CYP2U1, CYP7B1, ELOVL4, ELOVL6, ELOVL7, INSIG1, LCLAT1, LDLR, MED30, PEX11A, PIK3C2A, PIK3R3, PIP5K1B, PLA2G12A, PLA2G4C, PTGS2, RORA, SEC24A, SGMS2, SLC27A2, and SPTLC2 at 6 or 16 h of infection (Table 4). This evidence concerns the gene PTGS2 and infection.
