Abstract:Glucose is a major source of energy for living organisms and its transport in vertebrates is a universally conserved property. Of all cell lineages, human erythrocytes express the highest level of the Glut1 glucose transporter with >200,000 molecules/cell. However, we recently reported that erythrocyte Glut1 expression is a specific trait of vitamin C-deficient mammalian species, comprising only higher primates, guinea pigs and fruit bats (Montel-Hagen et al., Cell, 2008). We now show that in all other … Show more
