Transforming growth factor beta (TGF-β)1 regulation of gene expression patterns of cell cycle elements. GeneSpring was used to search the normalized 15,000 microarray data. A signal to control ratio above 2.5 was defined as upregulation (red). A signal to control ratio below 0.4 was defined as downregulation (blue). Ratios between 0.4 and 2.5 were considered unregulated (black). Outlined genes were not represented in the 15,000 gene database.
