Caption of KEGGview and Graphviz Pathway figures

Each figure shows an enriched KEGG pathway, either in Graphviz representation or KEGG representation.
The boxes of expressed genes are colored.
The colors represent the log2 fold-change (LFC) between control and PTEN knockout .
The LFC is limits ares set to the range of -2.3 and 2.3, which is optimized for the cellular senescence pathway.
LFC that exceed these limits are colored in the colors of the limit, i.e. the most intense color.
