Figure 5B shows the normalised densitometry units (NDUs) with respect to the α-actin loading reference for GLUT4 membrane expression demonstrated a significant seven-fold increase (6.7 ± 0.25 NDU) in CHF compared to the sham 1 (0.95 ± 0.2 NDU). This evidence concerns the gene SLC2A4 and congestive heart failure.
