SLC2A4 and CADASIL: To shed light on the mechanism of previously observed lower FDG-PET value in the CADASIL subjects (Tuominen et al., 2004), we investigated gene expression levels of GLUT isoforms [SLC2A2 (GLUT2), SLC2A3 (GLUT3), and SLC2A4 (GLUT4)] in VSMC models of CADASIL and control subjects.
