Targeting strategy

Gene targeting strategy for B-hLAT1 mice.
Exons 1-10 of the mouse Slc7a5 gene (encoding the full-length protein) were replaced by human SLC7A5 exons 1-10 to generate humanized B-hLAT1 mice.
-
mRNA expression analysis
-
Strain specific analysis of LAT1 gene expression in wild type (WT) mice and B-hLAT1 mice by RT-PCR. Mouse Slc7a5 mRNA was detectable only in brain of WT mice (+/+). Human SLC7A5 mRNA was detectable in homozygous B-hLAT1 mice (H/H) but not in WT mice (+/+).
-
Protein expression analysis
-
Strain specific LAT1 expression analysis in homozygous B-hLAT1 mice by western blot. Brain was collected from wild type (WT) mice (+/+) and homozygous B-hLAT1 mice (H/H), and analyzed by western blot with anti-LAT1 antibody. LAT1 was detectable in WT mice (+/+) and homozygous B-hLAT1 mice (H/H) due to the cross-reactivity of antibodies. Human LAT1 was exclusively detectable in homozygous B-hLAT1 mice (H/H).
