Figure 3From: Effects of dairy consumption on SIRT1 and mitochondrial biogenesis in adipocytes and muscle cellsEffects of serum treatment on mitochondrial biogenesis in human adipocytes. Cultured human adipocytes were incubated for 48 hours with human serum collected on day 0 (baseline), 7 or 28 after high dairy diet or soy-based control diet. (a) Uncoupling protein 2 (UCP2) and (b) PGC-1α were significantly increased by dairy at day 7 compared to baseline and soy-based diet. Values are expressed as means of % change to baseline ± SE (n = 4 to 5 subjects/group). Gene expression data are normalized to 18S. Differing letters above the bars denote significant differences between groups, p ≤ 0.05.Back to article page
