Effect of IH on glucose tranporter 4 (GLUT4) and proliferator-activated receptor gamma coactivator-1α (PGC-1α) expression in skeletal muscle. Effect of 5-wk IHH, IHL, and CTL on PGC-1α and GLUT4 protein content in skeletal muscle. Representative Western blots of PGC-1α protein expression (A), GLUT4 cytosolic protein expression (B), and GLUT4 membrane protein expression (C) are shown. Samples on the autoradiographs (Western blot images panels) are expressed as percentage of the CTL group. Ratio between GLUT4 membrane protein expression and GLUT4 cytosolic protein expression were represented in D. Intensity units results are means ± SE and *P < 0.05 significantly different from the CTL group (n = 6 per group). Correlation between GLUT4 (Membr.Prot./Cyto.Prot) and slope A from ITT is shown (E).
