It has been reported that C/EBPδ causes G0/G1 proliferative arrest in chronic myelogenous leukemia cells (KCL22 and K562) by down-regulating c-Myc and cyclin E and up-regulating p27 (Kip1) [52], and C/EBPδ is induced in growth arrested mammary epithelial cells by activating genes related to cell cycle regulation, including septin 7, regulator of chromosome condensation I, and DIRAS family, GTP-binding RAS-like 3 [53]. The gene discussed is MYC; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
