Figure 5. Effects of exercise or/and cold exposure on expression of mitochondrial biogenesis-related genes in the inguinal adipose tissue. Data are presented as means ± SE (n=8 per group). (A) peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α); (B) nuclear respiratory factor 1 (NRF1); and (C) mitochondrial transcription factor A (Tfam) relative to the expression level of glyceraldehyde 3-phosphate dehydrogenase (GAPDH). Two-way ANOVA results: (A) temperature: 0.176, exercise: 0.117, interaction 0.417 (B) temperature: 0.011, exercise: 0.01, interaction 0.000 (C) temperature: 0.475, exercise: 0.000, interaction 0.001. Different letters indicate significant differences (p < 0.05) between groups.
