AR and neoplasm: Further, NDRG1 expression was positively correlated to the histological Grade (G3) and with Ki67 (p < 0.0001), and inversely correlated to the expression of ER (p < 0.0001), PgR (p < 0.0001), androgen receptor (AR) (p = 0.0182), Her2 status (p = 0.009) and tumour-infiltrating lymphocytes (TILs) presence (p = 0.008).
