To identify the neuronal specific MEIS1 targets, we also searched for the overlaps between the DEGs present only in SK-N-SH cells and the RLS brain tissues (SK-N-SH is a neuroblastoma cell line and may be superior to HEK293 for identification of the neuronal specific MEIS1 targets); 40 genes were common between these two conditions (S5 Table). Here, MEIS1 is linked to neuroblastoma.
