Association of BMP6 expression with OS of breast cancer patients by ER status. OS by BMP6 expression in (A) ER+ and (B) ER− tumors. Gene sets enriched in (C) BMP6 high ER+ tumors, and (D) BMP6 low ER+ tumors. BMP, bone morphogenetic protein; OS, overall survival; ER, estrogen receptor; ER+, ER-positive; ER−, ER-negative.
