Figure 5. Non uniform distribution of reads across genome in control datasets.
(a) Pileup analysis of tag distributions around transcription start sites (TSS) for MyoD 2DM, control (empty vector ChTAP) 2DM and input DNA. All ENSEMBL protein-coding genes are included in the analysis irrespective of their expression status. The graph shows reads piled up (not extended) divided by total non-duplicated mapped reads plotted around TSS. (b) Pileup analysis of input DNA reads around TSS. Input reads pileup (not extended) scaled to max in window being 1.0 and a corresponding relationship to average positional GC percentage (x-axis) suggests that there is a correlation between increased input reads and GC content around the TSS. GM: myoblasts in growth media.
