The expression of most of the genes encoding enzymes related to the degradation of fatty acids (Acadm, Acot2 and Ehhadh) and cytochrome P450, was upregulated in the liver of infected mice Infection, which also increased the expression of the carnitine transporters Slc22a5 and Slc25a20 that shuttle fatty acids into mitochondria for oxidation. The gene discussed is SLC22A5; the disease is infection.
