Therefore, we aimed to identify differentially expressed circRNAs in diabetic mouse kidneys to explore the possible roles of dysregulated circRNAs in diabetic nephropathy development.<h4>Results</h4>Diabetic BKS-Lepr<sup>em2Cd479</sup>/Nju (BKS-DB/Nju) mice and their nondiabetic wild-type littermates of C57BL/KsJ wild-type (WT) mice were used as experimental animals. This evidence concerns the gene LEPR and diabetic kidney disease.
