SLC5A2 and Hyperglycemia: In this study, we explored the brown adipose tissue (BAT) and white adipose tissue (WAT) transplantation, and the use of bone marrow mesenchymal stem cell therapy (BM-MSC) combined with sodium-glucose co-transporter-2 (SGLT2) inhibitor treatment and calorie restriction in the BTBRob/ob model, recognized as a robust representation of DKD featuring hyperglycemia, obesity, time-dependent albuminuria, and histological changes.
