PGRMC1 and breast carcinoma: Clinical relevance of PGRMC1 expression and survival obtained through Kaplan–Meier plotter (KM plotter) tool (http://kmplot.com/analysis) demonstrated positive association between high PGRMC1 mRNA expression in breast cancer patients and significantly poorer survival probability (P = 3.8e−05) compared with patients in whom PGRMC1 mRNA expression is low (Fig. 1d).
