Regulated protein networks in FLA2 versus FLB1 leukemias. Protein abundance and phosphorylation data were analyzed with the STRING database (http://string.embl.de) resulting in a network composed of 2779 nodes and 29 386 edges. A GO analysis was performed for extracting significant (P < .05) subsets of proteins differentially regulated in FLA2 and FLB1 leukemias. Shown are the 4 most significant subnetworks affected: chromatin and histone modifiers, protein kinases, RNA processing, and nuclear import/export. Proteins/nodes are grouped according to their function and/or family. Color code indicates differentially expressed and/or phosphorylated proteins in FLA2 and FLB1 leukemias as described in the caption.
