Effect of dietary pterostilbene supplementation on the expression levels of hepatic genes related to mitochondrial function of 21-day-old broilers challenged with diquat. Values are means with their SEs represented by vertical bars (n = 6). Abbreviations: CON, broilers received a basal diet from 1 to 21 D of age; DQ, broilers were injected with diquat solution at 20 D of age; NRF1, nuclear respiratory factor 1; PGC1α, peroxisome proliferators-activated receptor gamma coactivator 1 alpha; PT, broilers received a pterostilbene-supplemented diet from 1 to 21 D of age; SIRT1, sirtuin 1; SS, birds were injected with sterile saline at 20 D of age; TFAM, transcription factor A, mitochondrial.
