Fig. 3. Effects of different duration of HF diet exposure on serum leptin levels and HPA axis activity in DIO and DR rats.

Fig. 3

a, b Note that PVN NE levels in DIO rats are elevated after 6 weeks of HF in spite of higher leptin levels. c, d DR rats have an activated stress axis in response to HF diet exposure, while DIO rats do not. Bars with different notations are significantly different from each other (p < 0.05). 6–8 rats/group
