Origin: The Lepr knockout rats were generated by CRISPR/Cas9. Two pairs of synthesized oligonucleotides for gRNA targeting on the exon 4 of Lepr, TAGGCAAATCATCTATAACTTC and AAACGAAGTTATAGATGATTTG; TAGGCTGAAAGCTGTCTTTCAG and AAACCTGAAAGACAGCTTTCAG were microinjected into Sprague Dawley (originally from Charles River) zygotes. The rat was genotyped by PCR with the primers, 5-prime-CTTGTGTCCAGAGCCTTCCTATAAC and 5-prime-ATTCCCCATGTTGTCTAGTAGTGATC. For genotyping, a 662-bp fragment of WT and a 368-bp fragment of the Lepr knockout gene were amplified with PCR. Founder 2 was chosen to establish a colony (designated as Lepr-/-), which carried a 298-bp deletion from No. 90043 bp to 90341 bp in the Lepr genome DNA sequence (NC_005104.4) and a 4-bp insertion and resulted in a termination codon TGA, deleting 997 amino acid of LEPR. Western blot analysis of total protein from liver tissue of the Lepr-/- rats confirmed the absence of LEPR.
