Inducible expression of FoxP1 in neuroblastoma cell lines and physiological FoxP1 levels in primary neuroblastomas. (a) Inducible FoxP1 protein expression in FOXP1- versus GFP-expressing neuroblastoma cell lines 48 h after induction of transgene expression. (b) Physiological FoxP1 protein levels in primary tumors; FOXP1 transcript levels are indicated as log intensities (microarray data).
