嗅觉受体(ORs)是G蛋白偶联受体,除了在嗅觉上皮中作为气味探测器的作用外,还具有重要的感觉功能。在此我们描述了其中一种嗅觉受体Olfr1393作为肾脏葡萄糖处理调节因子的新作用。Olfr1393特异性地在肾脏近端小管中表达,而肾脏近端小管是肾脏重吸收葡萄糖的部位。Olfr1393基因敲除小鼠表现出尿糖丢失和葡萄糖耐量改善,尽管血糖正常且胰岛素水平正常。与这种表型一致的是,Olfr1393基因敲除小鼠的Sglt1(一种关键的肾脏葡萄糖转运蛋白)的管腔表达显著降低,揭示了一条涉及Olfr1393和Sglt1的新的调节途径。此外,通过对1400多种化学物质进行大规模筛选,我们首次揭示了Olfr1393的配体特征,为这种新的信号通路的生理调节潜在途径提供了新的见解。
Olfactory receptors (ORs) are G protein-coupled receptors which serve important sensory functions beyond their role as odorant detectors in the olfactory epithelium. Here we describe a novel role for one of these ORs, Olfr1393, as a regulator of renal glucose handling. Olfr1393 is specifically expressed in the kidney proximal tubule, which is the site of renal glucose reabsorption. Olfr1393 knockout mice exhibit urinary glucose wasting and improved glucose tolerance, despite euglycemia and normal insulin levels. Consistent with this phenotype, Olfr1393 knockout mice have a significant decrease in luminal expression of Sglt1, a key renal glucose transporter, uncovering a novel regulatory pathway involving Olfr1393 and Sglt1. In addition, by utilizing a large scale screen of over 1400 chemicals we reveal the ligand profile of Olfr1393 for the first time, offering new insight into potential pathways of physiological regulation for this novel signaling pathway.
