IL2 and breast cancer: A follow-up analysis revealed that DOCR-linked genes were specifically enriched in a few Hallmark pathways encompassing a myriad of pathologic processes that may impact breast cancer pathophysiology: mTORC1, Hedgehog signaling, and estrogen response, controlling cell proliferation; E2F regulation control of cell cycle and replication; IL2/STAT5 and ROS signaling involved in ferroptosis cell death and immune response, (Supplementary Fig. S4B).
