FIGURE 4.
Differentially-expressed genes across circannual rhythm of hibernation in three brain regions. (A–C) Circles represent the homeothermic (red) and heterothermic (blue) portions of the hibernator’s year, arrows the sequence of physiological transitions. Two numbers are given on the inside of each arrow, decreasing in gray, increasing in black; their sum is the total DE between those two states (Supplementary Figure 2). Numbers outside the circles are the total number of DE genes (q < 0.001)/number of pass-filter genes detected in that brain region. (D) Venn diagram of common and unique DE genes among the three brain regions.
