Olfactory receptors are G protein-coupled receptors that serve to detect odorants in the nose. Additionally, these receptors are expressed in other tissues, where they have functions outside the canonical smell response. Olfactory receptor 1393 (Olfr1393) was recently identified as a novel regulator of Na(+)-glucose cotransporter 1 (Sglt1) localization in the renal proximal tubule. Glucose reabsorption in the proximal tubule (via Sglt1 and Sglt2) has emerged as an important contributor to the development of diabetes. Inhibition of Sglt2 is accepted as a viable therapeutic treatment option for patients with type 2 diabetes and has been shown to delay development of diabetic kidney disease. We hypothesized that Olfr1393 may contribute to the progression of type 2 diabetes, particularly the development of hyperfiltration, which has been linked to increased Na(+) reabsorption in the proximal tubule via the Sglts. To test this hypothesis, Olfr1393 wild-type (WT) and knockout (KO) mice were challenged with a high-fat diet to induce early-stage type 2 diabetes. After 16 wk on the high-fat diet, fasting blood glucose values were increased and glucose tolerance was impaired in the male WT mice. Both of these effects were significantly blunted in the male KO mice. In addition, male and female WT mice developed diabetes-induced hyperfiltration, which was attenuated in the Olfr1393 KO mice and corresponded with a reduction in luminal expression of Sglt2. Collectively, these data indicate that renal Olfr1393 can contribute to the progression of type 2 diabetes, likely as a regulator of Na(+)-glucose cotransport in the proximal tubule.
