Furthermore, except for an increase of NDRG1/2/3/4 expression observed in the MCF-7 model after Slug over-expression, the analysis of the GEO24202 and GSE41313 datasets does not correlate the expression of NDRG1 and the other members of the NDRG family with the process of EMT in BC (Fig. S2C–E). This evidence concerns the gene NDRG1 and breast cancer.
