Figure 1.

Hierarchical clustering of the 203 genes for which RA treatment of B16 cells reverts the expression towards that of melan-a cells. Average linkage was used with a Euclidean metric. The green-red color scale refers to log base two expression ratios with expression in untreated B16 cells as the denominator in all cases. Grey cells represent values which failed to pass the minimum expression level filter.
