This induced C/EBPδ can suppress FBXW7 in breast cancer, consequently increasing oncogenic mTOR/AKT/S6K1 signaling [166,167,168,169,170,171,172,173,174,175] as well hypoxia-inducible factor-1α (HIF-1α) required for hypoxia adaptation, thereby promoting tumor metastasis [74]. Here, CEBPD is linked to breast cancer.
