Mice deficient in p45NF-E2 that were generated by gene targeting have high mortality from bleeding resulting from severe thrombocytopenia. Survivingp45nf-e2\u2212\/\u2212 adults have mild anemia characterized by hypochromic red blood cells (RBCs), reticulocytosis, and splenomegaly. Erythroid abnormalities inp45nf-e2\u2212\/\u2212 animals were previously attributed to stress erythropoiesis caused by chronic bleeding and, possibly, ineffective erythropoiesis. Previous studies suggested that CNC factors might play essential roles in regulating expression of genes that protect cells against oxidative stress. In this study, we found that p45NF-E2\u2013deficient RBCs have increased levels of reactive oxygen species and an increased susceptibility to oxidative-stress\u2013induced damage. Deformability of p45NF-E2\u2013deficient RBCs was markedly reduced with oxidative stress, and mutant cells had a reduced life span. One possible reason for increased sensitivity to oxidative stress is that catalase levels were reduced in mutant RBCs. These findings suggest a role for p45NF-E2 in the oxidative-stress response in RBCs and indicate that p45NF-E2 deficiency contributes to the anemia inp45nf-e2\u2212\/\u2212 mice.<\/jats:p>","DOI":"10.1182\/blood.v97.7.2151","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T08:46:47Z","timestamp":1027759607000},"page":"2151-2158","update-policy":"https:\/\/doi.org\/10.1182\/blood.2019cm0000","source":"Crossref","is-referenced-by-count":40,"title":["Reduced
