Original Article


Deregulated mitochondrial metabolism and biogenesis have been studied in acute myeloid leukemia (AML); yet, the relevance of mitochondrial-encoded gene expression on AML outcomes is unknown. This study was conducted to assess clinical significance of expression of mitochondrial-encoded genes, namely ND3, SDHB, Cytochrome b, Cytochrome C, and ATP6, in pediatric AML. Pediatric AML patients from July 2013 to June 2016 were enrolled in this prospective study. Relative genes expression was determined using real-time PCR, and expressed as fold change. 123 AML patients were enrolled, median age 10 (range 0.7–18 years). ND3 gene expression was significantly increased in poor-risk cytogenetics (P = 0.03). In univariate analysis, high ND3 and ATP6 gene expression was significantly associated with inferior EFS (P = 0.01 and P = 0.04, respectively) and OS (P = 0.02 and P = 0.01, respectively), whereas, in multivariate analysis, ND3 gene expression emerged as the only independent prognostic factor for EFS and OS (P = 0.04 and P = 0.03). ND3 gene expression is a significant predictor of EFS and OS in pediatric AML, and should be evaluated as a potential biomarker.
