NDRG2 mRNA levels are down-regulated in tumor tissue from breast cancer patients and co-vary with Myc mRNA levels. Normalised mRNA expression of NDRG2 and Myc, respectively, was determined in normal and affected tissue from breast cancer patients. Lines represent mean expression. ** p < 0.005 compared to the normal group using a two-tailed Mann-Whitney test. A weakly significant positive correlation was found between NDRG2 and Myc mRNA levels for normal samples (p = 0.0238) and for tumor samples (p = 0.0113), using a Spearman's correlation test.
