Heatmap of differentially expressed genes in xenograft models. Hierarchical clustering of the 67 differentially expressed genes (false discovery rate < 0.05) involved in the KEGG homo sapiens glycerophospholipid pathway hsa:00564, choline transport or directly involved in conversion from choline to glycine (Red: high expression compared to mean expression in xenograft samples. Blue: low expression compared to mean expression in xenograft samples). The microarray data was centred across genes and clustered across genes and samples using Euclidian distance and complete linkage.
