Figure 7. Dexamethasone injection did not shift phase of the peripheral clock.

Dexamethasone (dex) was injected to mice at ZT 5 once a day for two continuous days. (A) Average PER2::LUC peak phases of each organ for each group. Numbers next to plots indicate the rates of mice whose PER2::LUC expression was rhythmic. (B) Averaged cosinor amplitude of each organ for each group. Graphs using data from mice whose PER2::LUC expression was rhythmic. All values are expressed as mean ± or + SEM.
