Expression plots for around-the-clock RNA-seq data from [ 25 ] for Tfrc showing mRNA (top panel; exonic reads) and pre-mRNA (bottom panel; intronic reads) for Smg6 mutants (yellow) and controls (blue). RPKM values of individual mouse livers are shown as dots with solid lines connecting the means across time points. Dashed lines represent rhythmic curve fittings to the data, as described in [ 25 ]
