To further understand the role and interactions between FUT2, RASIP1 and DE genes, expression of orthologs Fut2, Fn1, Kmt2d, Muc16, Mtap and Rasip1 were measured by gene array in ME of wildtype mice at multiple time points (from 3 hours to 7 days) post-infection with NTHi (Figure 4 and Tables 3, 4). This evidence concerns the gene FUT2 and infection.
