Patterns of differential expression for collagen and cytokeratin genes in multiple normal and tumor tissues. The data are shown in a table format, in which rows represent individual genes and columns represent individual normal tissue. The color in each cell reflects the differential expression level of the corresponding gene in a particular tissue. A four color code was used to represent gene induction and repression in cancer libraries (dark green: 'normal-specific', i.e. not expressed in tumor libraries; light green: downregulated in tumor libraries; orange: upregulated in tumor libraries; red: 'tumor-specific'). If there was no significant change in gene expression between normal and tumor libraries or in case of missing/excluded data, the gene was given in a black color. The number inside the colored cells indicates the statistical significance (p-value < 0.01 after Bonferroni correction). See additional information for the full data.
