Differential gene expression activities at three types of putative SPIB target genes. In the figure, T-value and Z-value are results of t-test and Mann-Whitney U test, respectively, for gene expression profiles between putative SPIB target genes (i.e. 'C', 'B', and 'A' genes) and the rest of genes in lenalidomide treated ABC DLBCL cell lines (i.e. OCI-Ly 10, and TMD8; hr represents hours of treatment). Positive and negative T-values (Z-values) are colored by red and green in the figure.
