Relative clock gene expression over time after serum shocked primary fibroblasts.

<p>Fitted sin graphs of the expression and mean ± SD of the mean from three individual patients per group are shown. The time of serum removal is 0 in the graphs and the relative expression is normalized to the expression before serum (at time = −2). Δb indicates the general difference in the expression i.e., the baseline of the expression. Phase differences are marked as red solid lines and the difference is indicated in hours.
