GAD1 and Hypoglycemia: Current results show that in the female, basal VMNdm GABA neuron GAD1 and GAD2 transcripts are respectively suppressed by or are refractory to GLUT2; evidence that GLUT2 stimulates both gene profiles during hypoglycemia points to a shift in direction of GLUT2 regulation of GAD1 gene expression, i.e. from negative to positive, and a gain of control of GAD2 mRNA profiles during eu- versus hypoglycemia.
