The receptor-interacting protein kinase 3 (RIP3) associates with RIP1 in anecrosome complex that can induce necroptosis, apoptosis, or cell proliferation.We analyzed the expression of RIP1 and RIP3 in CD34+ leukemia cells from acohort of patients with acute myeloid leukemia (AML) and CD34+ cells fromhealthy donors. The gene discussed is CD34; the disease is leukemia.
