FUT1 and infection: Analysis of DEGs encoding glycosyltransferases associated with HBGA/Lewis biosynthesis (Fig. 8, Additional file 1) indicated that the expression of fucosyltransferase-encoding gene (FUT1) responsible for transfer of fucose to GalNAc was marginally downregulated after G9P[13] and G5P[7] while the infection with RVC led to its significant upregulation.
