B, C. Boxplots reporting LPS-induced changes (Log2FC) for each of the four RNAPII kinetic rates in c-mycwt/wt (wt) and c-myc∆/∆ cells for Myc-dependent (B) and Myc-independent (C) induced and repressed genes. p-values obtained with two-sample Wilcoxon tests for the comparison between c-mycwt/wt and c-myc∆/∆ cells are reported. The RNAPII ChIP-seq time-course was performed on two biological replicates (each on pools of cells from > 10 mice), and reads were merged after sequencing.
