SLC2A3 gene expression tended to be lower but was only different from SLC2A2 and SLC2A4. Since the insulin-dependent transporter GLUT4 was previously assessed in hypertension models and in diabetes as a model of small vessel disease, we focused on this specific transporter for the gene product studies in relation to the insulin-independent GLUT2. The gene discussed is SLC2A3; the disease is diabetes mellitus.
