Roles of sensory receptors in non-sensory organs: the kidney and beyond.

Olfactory receptors (ORs), taste receptors and opsins are well-known for their pivotal roles in mediating the senses of smell, taste and sight, respectively. However, in the past two decades, research has shown that these sensory receptors also regulate physiological processes in a variety of non-sensory tissues. Although ORs, taste receptors and opsins have all been shown to have physiological roles beyond their traditional locations, most work in the kidney has focused on ORs.

Handling the sugar rush: the role of the renal proximal tubule.

Blood glucose homeostasis is critical to ensure the proper functioning of the human body. Through the processes of filtration, reabsorption, secretion, and metabolism, much of this task falls to the kidneys. With a rise in glucose and other added sugars, there is an increased burden on this organ, mainly the proximal tubule, which is responsible for all glucose reabsorption.

SGLT2 inhibition leads to a restoration of hepatic and circulating metabolites involved in the folate cycle and pyrimidine biosynthesis.

Inhibition of sodium-glucose cotransporter 2 (SGLT2) by empagliflozin (EMPA) and other "flozins" can improve glycemic control under conditions of diabetes and kidney disease. Though they act on the kidney, they also offer cardiovascular and liver protection. Previously, we found that EMPA decreased circulating triglycerides and hepatic lipid and cholesterol esters in male TallyHo mice fed a high-milk-fat diet (HMFD).

Nascent shifts in renal cellular metabolism, structure, and function due to chronic empagliflozin in prediabetic mice.

Sodium-glucose cotransporter, type 2 inhibitors (SGLT2i) are emerging as the gold standard for treatment of type 2 diabetes (T2D) with renal protective benefits independent of glucose lowering. We took a high-level approach to evaluate the effects of the SGLT2i, empagliflozin (EMPA) on renal metabolism and function in a prediabetic model of metabolic syndrome. Male and female 12-wk-old TallyHo (TH) mice, and their closest genetic lean strain (Swiss-Webster, SW) were treated with a high-milk-fat diet (HMFD) plus/minus EMPA (@0.
