The primary aim of the present study was to investigate the acute gene expression
responses of PGC-1 isoforms and PGC-1a target genes related to mitochondrial
biogenesis (cytochrome C), angiogenesis (VEGF-A), and muscle
hypertrophy (myostatin), after a resistance or endurance exercise bout. In
addition, the study aimed to elucidate whether the expression changes of studied
transcripts were linked to phosphorylation of AMPK and MAPK p38.
Nineteen physically active men were divided into resistance exercise (RE,
n = 11) and endurance exercise (EE, n = 8) groups. RE group performed leg
press exercise (10 9 10 RM, 50 min) and EE walked on a treadmill (~80%
HRmax, 50 min). Muscle biopsies were obtained from the vastus lateralis muscle
before, 30 min, and 180 min after exercise. EE and RE significantly
increased the gene expression of alternative promoter originated PGC-1a exon
1b- and 1b’-derived isoforms, whereas the proximal promoter originated exon
1a-derived transcripts were less inducible and were upregulated only after EE.
Truncated PGC-1a transcripts were upregulated both after EE and RE. Neither
RE nor EE affected the expression of PGC-1b. EE upregulated the expression
of cytochrome C and VEGF-A, whereas RE upregulated VEGF-A and downregulated
myostatin. Both EE and RE increased the levels of p-AMPK and pMAPK
p38, but these changes were not linked to the gene expression
responses of PGC-1 isoforms. The present study comprehensively assayed
PGC-1 transcripts in human skeletal muscle and showed exercise mode-speci-
fic responses thus improving the understanding of early signaling events in
exercise-induced muscle adaptations.
