Figure 3From: Microarray analysis of tumor necrosis factor α induced gene expression in U373 human glioblastoma cellsPercentage of functional groups in clusters. Genes in clusters were annotated to functional groups. Percentage of the three most abundant groups within genes with annotated functions are depicted. Same color coding is used as in clusters of Fig. 2. Several clusters could be discriminated on the basis of the functional groups.Back to article page
