Expression level of CEBPA gene in acute lymphoblastic leukemia individuals.

Currently, acute lymphoblastic leukemia (ALL) has an overall survival of nearly 80% when it occurs in children, however cure rates among adults are far reduced. Leukemogenesis can be driven up by a slight change in the expression or function of certain transcription factors. CCAAT Enhancer Binding Protein Alpha (CEBPA) is a transcription factor with role in cell cycle regulation, granulocytic differentiation and more. Some studies suggest its oncogenic function. The potential role of CEBPA as an oncogene in ALL development has not been completely elucidated so far. Therefore, the aim of the present study was to evaluate mRNA level of CEBPA gene in 60 adult patients diagnosed with ALL. Quantitative analysis was performed by qPCR reaction. Analysis revealed that men tended to have higher and more variable CEBPA expression levels (P = 0.032). No associations for other parameters (ALL subtype, age, leukocytosis, blast percentage, Philadelphia chromosome presence, CD10 marker presence) were found. When comparing the results of CEBPA expression with patients suffering from acute myeloid leukemia, ALL cases showed statistically significant lower levels of CEBPA (P < 0.0000). It may seem that CEBPA expression level itself has potentially no effect on arising and progression of acute lymphoblastic leukemia, although it is a matter that needs further investigation.
