4.4 - Regulatory TF plots


TF ranking plot

For a given enriched motif, all human TF are ranked by the statistical −log10(P − value) assessing the anti-correlation level of candidate Master Regulator TF expression with average DNA methylation level for sites with the given motif. As a result, the most anti-correlated TFs will be ranked in the first positions. By default, the top 3 most anti-correlated TFs and all TF classified by TFClass database in the same (sub)family are highlighted with colors blue, red and orange, respectively.

TF ranking plot: family classification

Shown are TF ranking plots based on the score (−log10(Pvalue)) of association between TF expression and DNA methylation of an enriched motif in the LUSC cancer type. The dashed line indicates the boundary of the top 5% association score. The top 3 associated TFs and the TF family members=(dots in red) that are associated with that specific motif are labeled in the plot
