Description
Glut-1 was discovered in erythrocytes of some Japanese Shiba dogs. They have Glut-1 as well as Glut-4 in erythrocytes, while other Shiba dogs and other breeds have only Glut-4. Dog erythrocytes with Glut-1 showed much higher affinity for entry of glucose and oxidized ascorbic acid and greater capacity for ascorbic acid (AA) recycling than those with only Glut-4. Dog is among numerous AAsynthesizing species that normally do not have Glut-1 in erythrocytes. However, this variant of dog is the first example of an AA-synthesizing animal which maintains Glut-1 in erythrocytes throughout life. Shiba dogs can be a new animal model for further understanding the mechanism of regulation and functions of AA in the organism.
