Among patients with CEBPA mutations, 91% were in the CN-AML molecular high-risk group. Within this group, CEBPA mutations predicted better event-free (P &lt; .001), disease-free (P = .004), and overall survival (P = .009) independently of other molecular and clinical characteristics and were associated with unique gene and miRNA expression profiles. The major features of these profiles were upregulation of genes (eg, GATA1, ZFPM1, EPOR, and GFI1B) and miRNAs (ie, the miR-181 family) involved in erythroid differentiation and downregulation of homeobox genes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Pretreatment testing for CEBPA mutations identifies CN-AML patients with different outcomes, particularly in the molecular high-risk group, thus improving molecular risk-based classification of this large cytogenetic subset of AML. The gene and miRNA expression profiling provided insights into leukemogenesis of the CN-AML molecular high-risk group, indicating that CEBPA mutations are associated with partial erythroid differentiation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1200\/jco.2008.17.5554","type":"journal-article","created":{"date-parts":[[2008,9,22]],"date-time":"2008-09-22T20:14:30Z","timestamp":1222114470000},"page":"5078-5087","source":"Crossref","is-referenced-by-count":265,"title":["Prognostic Significance of, and Gene and MicroRNA Expression Signatures Associated With,\n                    <i>CEBPA<\/i>\n                    Mutations in Cytogenetically Normal Acute Myeloid Leukemia With High-Risk Molecular Features: A Cancer and Leukemia Group B Study"],"prefix":"10.1200","volume":"26","author":[{"given":"Guido","family":"Marcucci","sequence":"first","affiliation":[{"name":"From the Division of Hematology and Oncology, Department of Internal Medicine, and Division of Human Cancer Genetics, Department of Microbiology, Virology, Immunology, and Medical Genetics, Comprehensive Cancer Center, The Ohio State University, Columbus, OH;
