SOX11 expression profile across cancer cell lines and primary tumors showed concordance with DCX expression, except for human neural crest cells and pheochromocytoma, which could partially reflect earlier SOX11 induction during neural crest development and SOX11 lineage specificity (Potzner et al, 2010; Figs 3A, bottom and S3F). This evidence concerns the gene DCX and pheochromocytoma.
