Effect of exercise on photoperiod-regulated hypothalamic gene expression and peripheral hormones in the seasonal Dwarf Hamster Phodopus sungorus.

There was a 26% increase in fat mass in LD-RW hamsters compared to LD-C, but this did not achieve significance (LD-RW 7.92±0.49 g, LD-C 6.27±0.94 g, SD-RW 9.59±1.12 g, SD-C 3.08±0.52 g).

There was an effect of photoperiod on vimentin gene expression ( Figure 6A ) with SD groups showing reduced expression compared to the LD-RW group (Kruskalmc P<0.05), but did not quite achieve significance for the LD-C group.
