SLC2A4 and Hyperglycemia: We determined the molecular effect of BA and hyperglycemia on GLUT4 expression in HASMCs and found that 15 μM BA partly, while 20 μM of BA completely, reversed hyperglycemia-mediated decreased expression of GLUT4 mRNA (Figure 2a, b) and protein (Figures 2c, d and S1c, see online supplementary material) as well as hyperglycemia-mediated decreased GLUT4 reporter activity (Figure 2e) and 14C-DG uptake (Figure 2f).
