Additionally, aberrations in the mechanisms involved in gene expression have been identified to have a role in the development of AML. Contradictory evidence has been reported concerning the expression of the <em>CEBPA</em> gene in AML patients. Additionally, investigation into the expression of the <em>CEBPA-AS</em> gene has yet to be explored in AML patients. The aim of the present study was to investigate the relationship between the expression of the <em>CEBPA</em> and <em>CEBPA-AS</em> genes and AML in Iranian patients.<br> <strong><em>Methods:</em></strong> Using quantitative real-time PCR, the expression of the <em>CEBPA</em> and <em>CEBPA-AS</em> genes was examined in the peripheral blood samples of 58 patients with de novo adult AML, and in 20 healthy controls. &nbsp;&nbsp;&nbsp;<br> <strong><em>Results:</em></strong> Overall, <em>CEBPA</em> expression analysis showed a significant up-regulation in AML patients compared with healthy controls. Interestingly, a significant up-regulation of <em>CEBPA</em> was detected in the male AML patients. Significant <em>CEBPA</em> over-expression was observed in M0 (<em>p-value</em>=0.0001), M3 (<em>p-value</em>= 0.012) and M4 (<em>p-value</em>= 0.000) FAB subtypes. Our data has also demonstrated that <em>CEBPA</em> expression is up-regulated in favorable (<em>p</em>-v<em>alue</em>= 0.006) and adverse (<em>p-value</em>= 0.042) cytogenetic risk groups. In addition, the expression of <em>CEBPA</em> was significantly increased in AML patients with an abnormal karyotype. Ectopic expression of <em>CEBPA-AS</em> was detected in seven of the AML patients.<br> <strong><em>Conclusions:</em></strong> Our study provides evidence for the up-regulation of <em>CEBPA</em> and the ectopic expression of <em>CEBPA-AS</em> in AML patients, suggesting that these two genes may play an important role in the pathogenesis of AML. The role of <em>CEBPA and CEBPA-AS </em>in AML patients should be further explored. This will offer potential opportunities for the development of novel treatment strategies.<br> &nbsp;</div> Acute Myeloid Leukemia, CEBPA, CEBPA-AS, de novo, Expression. 136 141 http://rbmb.net/browse.php?a_code=A-10-134-1&slc_lang=en&sid=1 Milad Gholami mtu.q220@gmail.com 100319475328460017024 100319475328460017024 No Department of Medical Genetics, School of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
