BACKGROUND & OBJECTIVE: Acute myeloid leukemia (AML) is a hematopoietic malignancy caused by genetic abnormalities. Currently, molecular and genetic factors are routinely used as diagnostic and prognostic markers. FLT-3 is one of the most known diagnostic factors in AML. gene belongs to the ATP binding cassette family; it is known as one of the chemotherapy-resistant causes of AML. We aimed to study mutations and their association with gene expression in AML individuals.
For investigation, 80 AML individuals and 20 healthy controls were selected. This study was done in the Cancer molecular Pathology Research Center of Mashhad University of Medical Sciences (MUMS), Iran during 2017-2019. mutation was assessed by polymerase chain reaction (PCR); Real-time quantitative PCR was performed to measure the amount of gene expression. Bone marrow and blood smears of patients were evaluated in terms of morphology. SPSS 16.0 was used for data analysis.
mutation and overexpression were found in 18.8% and 23.8% of AML patients, respectively. Statistical analysis did not show any relationship or association between these two markers. Cuplike morphology was observed in blast cells in 21.25% of AML cases, which was associated with the presence of mutation.
and function independently. Survival studies to determine the exact role of overexpression in drug resistance issues would be suggested.
急性髓系白血病(AML)是一种由基因异常引起的造血系统恶性肿瘤。目前,分子和遗传因素被常规用作诊断和预后标志物。FLT-3是AML中最知名的诊断因素之一。该基因属于ATP结合盒家族;它是AML化疗耐药的原因之一。我们旨在研究AML患者中该基因的突变及其与基因表达的关联。
为进行研究,选取了80例AML患者和20例健康对照。本研究于2017年至2019年在伊朗马什哈德医科大学(MUMS)癌症分子病理学研究中心开展。通过聚合酶链反应(PCR)评估该基因突变;采用实时定量PCR检测该基因表达量。对患者的骨髓和血液涂片进行形态学评估。使用SPSS 16.0进行数据分析。
在18.8%的AML患者中发现了该基因突变,23.8%的患者存在该基因过表达。统计分析未显示这两个标志物之间存在任何关系或关联。在21.25%的AML病例中,原始细胞观察到杯状形态,这与该基因突变的存在相关。
该基因的突变和过表达独立发挥作用。建议开展生存研究以确定该基因过表达在耐药问题中的确切作用。
