In our previous study [14] which examined the expression of all 48 members of the NR superfamily in a cohort of normal and cancer breast tissues, we observed that (i) MR expression is lower in cancer compared to normal breast tissues and that (ii) MR is an independent predictor of metastasis-free survival in tamoxifen-treated breast cancer patients. The gene discussed is NR3C2; the disease is breast carcinoma.
