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). The gene discussed is SPTLC2; the disease is infection.
