Investigating the etiological causes of acute myeloid leukemia (AML) at the molecular level should help in identifying targets and strategies that would increase the efficacy of the current management regimens. Some genes may act as molecular diagnostics, of these ASXL1 and PHF6 are involved in regulation of gene expression, and BAX , and ARC, are pro- and anti-apoptotic molecules, respectively. In this study, peripheral blood samples were collected from 54 recently diagnosed AML patients in addition to 20 healthy individuals (the control group). Cellular RNA was extracted from all the samples and were subjected to quantitative analysis of the transcript levels of the four selected markers. Our data showed a significant elevation in the expression levels of PHF6 and ARC in AML patients, when compared to the controls (77.8% and 83.3%, respectively). On the other hand, ASXL1 and BAX exhibited increase, to a lesser extent, in the expression levels of the AML patients (52% and 55.6%, respectively). Our study also showed that the expression levels of ARC and PHF6 exhibited a concomitant increase and this could be correlated with poor prognosis of the cases. Thus, we can suggest these markers as reliable prognostic markers for prediction of AML outcomes.
在分子水平上研究急性髓系白血病(AML)的病因应有助于确定能够提高当前治疗方案疗效的靶点和策略。一些基因可作为分子诊断标志物,其中ASXL1和PHF6参与基因表达调控,而BAX和ARC分别是促凋亡和抗凋亡分子。在本研究中,除了20名健康个体(对照组)外,还采集了54例近期诊断为AML患者的外周血样本。从所有样本中提取细胞RNA,并对所选4种标志物的转录水平进行定量分析。我们的数据显示,与对照组相比,AML患者中PHF6和ARC的表达水平显著升高(分别为77.8%和83.3%)。另一方面,ASXL1和BAX在AML患者中的表达水平也有一定程度的升高(分别为52%和55.6%)。我们的研究还表明,ARC和PHF6的表达水平同时升高,这可能与病例的预后不良相关。因此,我们可以认为这些标志物是预测AML预后的可靠指标。
