(A) LCGs (red) and LNCGs (blue) in each expression category. All liver-expressed genes are ranked according to their expression levels (by using logarithm of intensity to base 10) and divided into 28 expression bins with each bin containing 300 genes except the highest one with 329 genes. The x-axis showed the mean expression value of each bin. (B) Abundance (using logarithm of spectral counts to base 2) of proteins encoded by LCGs, liver-expressed non-liver circadian genes (LNLCGs), LNCGs, and all liver-expressed genes (AL). (C) Mean expression values of LCGs, LNLCGs, LNCGs, and all liver-expressed genes among different tissues or temporal phases in the liver. (D) Standard deviations of LCGs, LNLCGs, LNCGs, and all liver-expressed genes among different tissues or temporal phases in the liver. (E) mRNA half-life of LCGs, LNLCGs, LNCGs, and all liver-expressed genes in ES cells. The boxes depict data between the 25th and 75th percentiles with central horizontal lines and solid circles representing the median and mean values, respectively, and with whiskers showing the 5th and 95th percentiles. P-values are calculated based on the Wilcoxon rank sum test. (*), P-value<0.05. (**), P-value<0.01. (***), P-value<0.001. NS, not significant.
