Alterations of expression levels by diet were observed for all Slc2as/Gluts; greater than two-fold were only observed for Slc2a3/Glut3 at E12.5, for Slc2a6/Glut6 at E9.5 and E18.5, for Slc2a8/Glut8 at E9.5, E12.5 and E18.5, and for Slc2a13/Glut13 at E9.5, regardless of diabetes exposure. This evidence concerns the gene SLC2A3 and diabetes mellitus.
