Finally, Gfi1 also decreases the pro-apoptotic effects of p53 in lymphoblastic leukemia by binding to the regulatory regions of pro-apoptotic genes, such as BAX, Pmaip1 (NOXA), and Bbc3 (PUMA); blocking p53 binding; and decreasing methylation of p53-K372 [12]. The gene discussed is BBC3; the disease is acute lymphoblastic leukemia.
