High expression of MAX in breast cancer patients with ER+ or luminal A subtype of ER+ tumors displayed significantly improved overall survival (Figure S2A,B, p = 0.0011 and p = 0.0062, respectively) while a high expression of MAX in ER− or basal-like TNBC subtype displayed significantly worse survival over time (Figure S2C,D, p = 0.008 and p = 0.014, respectively). Here, MAX is linked to breast cancer.
