Effect of L-ornithine on PER2::LUC oscillation in MEFs.
(a,c,e,g) Representative data for MEFs treated with water or 1 mM l-ornithine. Filled arrows indicate the time point of l-ornithine application; open arrowheads indicate the peak phase. (b,d,f,h) Summary of the peak phase of mPer2 expression. All values are expressed as means ± SEM (n = 4 mice per group).
