MEGF10 and neuroblastoma: There was an inverse relationship between MEGF10 DNA methylation and expression (Figure 3C) and MEGF10 could be reactivated by treating hypermethylated cells with the DNA demethylating agent aza‐deoxycytidine (Figures 3D and 4A), suggesting that DNA methylation plays a mechanistic role in the control of MEGF10 expression in the majority of neuroblastoma cell lines.
