In luminal A tumors, we found overexpression of GPX1, CCS, ENDOG, MAPK3, and RIPK3 proteins involved in ROS; PRDX3 and SOD1 in the ROS and PMM processes; TIMM10B, NDUFA13, APOOL, MICOS13 and TIMM10 of the MMO process; BCL2 involved in the MMO, PMM and ROS processes; PARK7 in MIT, PMM and ROS processes; ATG2B in MIT; FIS1 in FIS and MIT and MTFR1L in FIS compared to basal-like BC tumors. The gene discussed is RIPK3; the disease is breast cancer.
