Figure 2

Heatmap of IL6-correlated genes. The heatmap of Pearson’s correlation coefficient (r) of the genes with IL6 was drawn by using R programming language. The r scores are represented in grayscale as reported in the color key. IL6 self-correlation was artificially set to the maximum score. Correlation score below 0.4 were considered not significant (NS). Genes not spotted on the array were defined NA (not available). The number of data sets in which the gene resulted significantly correlated with IL6 is reported on the right.
