SLC9A3 and diabetic kidney disease: Although our study focused on investigating the effects of dapagliflozin in regulating the association between the sodium–hydrogen exchanger (NHE3) and lipid rafts in proximal tubule cells, we realize dapagliflozin may have effects in other segments of the nephron where other membrane transporters and ion channels play a role in diabetic kidney disease and are regulated by lipid rafts.
