Cell cycle pathway gene expression. Shown is a GenMAPP http://www.genmapp.org rendering of a modified KEGG (Kyoto Encyclopedia of Genes and Genomes, http://www.genome.jp/kegg/) schematic of cell cycle pathway genes. Genes significantly overexpressed in CEPI relative to OSE are colored red. The execution of the cell cycle is depicted from left to right and individual phases identified below by I- beam brackets. Genes involved in maintaining G1 are generally under-expressed in CEPI while genes involved in G1 to S progression, G2, and M are over-expressed.
