Figure 4. Effects of HFD and niacin on gene expression of ER chaperones.

ERp44 gene expression in EWAT of wild-type mice (A) or HCA₂ ^−/− mice (B), Ero1-Lα gene expression in EWAT of wild-type mice (C) or HCA₂ ^−/− mice (D), and DsbA-L gene expression in EWAT of wild-type mice (E) or HCA₂ ^−/− mice (F). All values were normalized to 36B4. **P<0.01. Data are presented as mean ± SEM and are expressed as relative to the Control group set to one. AU, arbitrary units.
