NDRG2 and breast carcinoma: Further, ILC with abundant NDRG2 expression showed an inverse correlation (Pearson r: -0.3795, P<0.001) with high breast cancer HRneg/Tneg survival score associated with poor metastatic outcome in early stage TNBC [27] while correlation in IDC showing abundant NDRG2 was low (Pearson r: -0.0736, P = 0.0474) (S2 Fig).
