Moreover, in the case of control samples, we found overexpression of the proteins: PRDX2, PRDX5 and AIFM1 involved in ROS; TUSC2 in PMM; ALKBH7, RHOT1, SAMM50, IMMT and HSPA9 in the MMO; and FUNDC2 in MIT compared to luminal A and basal-like breast cancer tumors. This evidence concerns the gene HSPA9 and breast cancer.
