Figure 4.

Posterior probability density of transcript concentrations (number of transcripts per µg total RNA) for cancer cell lines (black) and cervix cancer (red). The data of 10 157 genes and ESTs were included, and the calculations were based on a pool of 10 cell lines and 12 cervix tumours. The median value of each distribution is shown as a vertical line and was slightly higher for the cell lines than for cervix cancer. Both distributions were skewed towards higher values, and less abundant transcripts were more frequent than high abundant ones.
