Diagnostic plots and unsupervised clustering analyses of gene expression profiles. (A) Boxplot visualization of log2 expression values and one-dimensional hierarchical clustering of all sample groups: control cell samples and those treated with IFNα2b, IFNγ and HeberFERON. (B) Multidimensional Scaling (MDS) of flat pattern filtered data. (C) Two dimensional hierarchical clustering of genes expression profiles with the highest SD between samples. On top, samples are grouped based on the similarity of their expression profiles
