It is the principal transporter for transfer of glucose between liver and blood[1] Unlike GLUT4, it does not rely on insulin for facilitated diffusion.
[9][10] Similarly, a recent study showed that lack of GLUT2 in β-cells doesn't impair glucose homeostasis or glucose-stimulated insulin secretion in mice.
[14] However, whilst a lack of GLUT2 adaptability[15] is negative, it is important to remember the fact that the main result of untreated gestational diabetes appears to cause babies to be of above-average size, which may well be an advantage that is managed very well with a healthy GLUT2 status.
GLUT2 appears to be particularly important to osmoregulation, and preventing edema-induced stroke, transient ischemic attack or coma, especially when blood glucose concentration is above average.
SLC2A2 was associated with clinical stages and independently associated with overall survival in patients with Hepatocellular carcinoma, and could be considered a new prognostic factor for HCC.
