SLC22A17 and infection: The RT–qPCR results showed that infection of 2L3 cells with pN + LS and pN − LS led to increasing expression of Lcn2 (Figure 7F) and Lcn2-c-myc (Figure 7G), which represented the levels of total and exogenous NGAL, respectively, while there were no differences in the levels of Slc22a17 (NGAL-R) expression (Figure 7H).
