NDRG1 and neoplasm: Our result show that NDRG1 is upregulated slightly in NBT compared with NB and NS, but NDRG1 levels increase significantly in FtMt-SY5Y cells compared with controls whether by Western blot or immunohistochemistry assay (Fig. 6b, c), indicating that elevated FtMt may inhibit tumor cell metastasis via NDRG1.
