FOXP2 and neuroblastoma: In one such study, multiple targets from prior ChIP‐chip studies (Spiteri et al, 2007; Vernes et al, 2007; Vernes et al, 2011) were found to be differentially expressed in human neuroblastoma cells stably transfected with FOXP2, including retinoic acid signaling genes, such as the retinoic acid receptor (RAR)‐β, RAR‐related orphan receptor (ROR)‐α, ROR‐β, ROR‐γ, and NEDD9 (Devanna et al, 2014).
