Revisiting the physiological roles of SGLTs and GLUTs using positron emission tomography in mice

摘要

Key points class="unordered" style="list-style-type:disc" id="tjp7223-list-0001">Glucose transporters are central players in glucose homeostasis.There are two major classes of glucose transporters in the body, the passive facilitative glucose transporters (GLUTs) and the secondary active sodium‐coupled glucose transporters (SGLTs).In the present study, we report the use of a non‐invasive imaging technique, positron emission tomography, in mice aiming to evaluate the role of GLUTs and SGLTs in controlling glucose distribution and utilization.We show that GLUTs are most significant for glucose uptake into the brain and liver, whereas SGLTs are important in glucose recovery in the kidney.This work provides further support for the use of SGLT imaging in the investigation of the role of SGLT transporters in human physiology and diseases such as diabetes and cancer.
