Effects of HFD and niacin on gene expression of transcription factors.

<p>PPARγ gene expression in EWAT of wild-type mice (A) or HCA₂^−/− mice (B). C/EBPα gene expression in EWAT of wild-type mice (C) or HCA₂^−/− mice (D). SREBP-1c gene expression in EWAT of wild-type mice (E) or HCA₂^−/− mice (F). All values were normalized to 36B4. ^*P<0.05, **P<0.01 compared to mice on control diet receiving vehicle. Data are presented as mean ± SEM and are expressed as relative to the Control group set to one. <b>AU</b>, arbitrary units.
