TL;DR: The extensive expression of GLUT2 and 5 (glucose/fructose and fructose transporters, respectively) in malignant human tissues indicates that fructose may be a good energy substrate in tumor cells and suggest that fructose uptake could be used for positron emission tomography imaging.

TL;DR: Functional uptake analyses support the hypothesis that astrocytes are involved in vitamin C recycling in the nervous system by avoiding the hydrolysis of dehydroascorbic acid produced by antioxidative protection.

TL;DR: The aim of this review focuses on integrating the current understanding of various glucose-sensing mechanisms described in the brain, thereby establishing a relationship between neuroanatomy and control of physiological processes involved in both metabolic and energy balance.

TL;DR: This review will compare the molecular and structural aspects of vitamin C and glucose transporters and their expression in endothelial or choroid plexus cells, which form part of the blood-brain barrier and blood-cerebrospinal fluid (CSF) barrier, respectively and describe SVCT and GLUT expression in different cells of the brain.

TL;DR: Tanycytes mediate, at least in part, the mechanism by which the hypothalamus detects changes in glucose concentrations, as demonstrated by Western-blot analysis, QRT–PCR and in situ hybridization.
