Heat maps of the ERG signatures. Derived gene expression (A) and microRNA expression signatures (B) associated with ERG expression in the group of CN-AML patients ≥ 60 years. Patients are ordered from left to right by increasing ERG expression. Expression values of the gene probe sets (microRNA probes) are represented by color, with blue indicating expression less than and red indicating expression greater than the median value for the given gene probe set (microRNA probe). For the gene expression heat map, up- and down-regulated genes mentioned in the text are indicated.
