STMN1 and neuroblastoma: We have previously shown that stathmin levels are important for the migration and invasion phenotype of neuroblastoma.9,10 To further investigate the role of stathmin expression in neuroblastoma metastasis, we used SK-N-BE(2)/TGL neuroblastoma control cells (CtrlshRNA) and their respective stable-knockdown stathmin cells (Stmn Seq2shRNA)9 (Supplementary Fig. 1a).
