Metabolic gene expression. (A) Expression of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α), nuclear respiratory factor 1 (NRF-1), mitochondrial transcription factor A (TFAM), glucose transporter 4 (GLUT4), normalized to the housekeeping gene, TATA binding protein (TBP) following treatment of C2C12 myocytes with 0.5% beetroot (BR) by volume for 4, 8, or 24 hours. (B) Gene expression of C2C12 myocytes following treatment with 0.5%, 0.25%, or 0.125% BR by volume for 24 hours. Note. Data are presented as group mean ± standard deviation. *p < 0.05, **p < 0.01, ***p < 0.001 compared with control. ^†p < 0.05 between 0.5% and 0.125% BR by volume. ^‡p < 0.05 between 0.5% and 0.25% BR by volume.
