چکیده

objective: chronic myeloid leukemia (cml) is a malignant clonal disorder of hematopoietic stem cells which results in increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. investigations have shown different types of bcr- abl variants in these patients. in iran only 3 types of these variants have been identified because most of the clinical laboratories usually use only few sets of primers which can not detect all types of the variants simultaneously. in this study we developed a method with which all types of variants in chronic myeloid leukemia patients can be recognized. materials and methods: blood samples from 100 persons who were under treatment or diagnosis for cml were received from clinical laboratory. rna was extracted from 600 µl of each sample using roche commercial kit and converted to cdna by reverse transcriptase enzyme the cdnas were analyzed for bcr- abl variants using two sets of primers. all samples were also studied by rt- multiplex nested pcr method. results: rt-multiplex pcr could detect bcr-abl in all samples which were positive for these fusion gene mrna. from 100 collected samples 46 percent were positive and 54 percent were negative by rt-multiplex pcr method and 44 percent were positive and 56 percent were negative by rt-multiplex nested pcr method. conclusion: by using one step pcr we detected more variants of bcr- abl in one tube at shorter time and lower cost. this method showed 100 percent specificity and can further be improved by taking more samples and also real time pcr for quantitative analysis.

BCR-ABL fusion genes and laboratory findings in patients with chronic myeloid leukemia in northeast Iran

Background: A specific chromosomal abnormality, the Philadelphia chromosome (BCR-ABL fusion), is present in all patients with chronic myeloid leukemia (CML). The b2a2 and b3a2 fusion mRNAs encode p210 fusion protein p210 and e1a2 encode p190. The aim of this study was to evaluate the frequency of BCR-ABL fusion transcript variants in Northeast of Iranian CML patients and to compare the laborato...

Frequency of BCR-ABL Fusion Transcripts in Iranian Azeri Turkish patients with Chronic Myeloid Leukemia

Background: The Philadelphia chromosome (Ph) characterized by t (9; 22) (q34; q11.2) is a reciprocal translocation giving rise to a chimeric BCR-ABL fusion gene. Incidence of Ph chromosome is over 98% in Patients with Chronic Myeloid Leukemia (CML) and around 20% in acute lymphoblastic leukemia (ALL). The finding of this fusion gene is essential for diagnosis of CML by detection of various fusi...

Inhibition of apoptosis by BCR-ABL in chronic myeloid leukemia.

BCR-ABL expression is presumed to effect clonal expansion in chronic myeloid leukemia (CML) by deregulation of cell proliferation. However, most studies have found that relative rates of cell proliferation are not increased in CML. Moreover, we found that CML progenitors display a normal proliferative response to growth factors and do not manifest greater proliferative potential than normal pro...

Bcr-abl Silencing by Specific Small-Interference RNA Expression Vector as a Potential Treatment for Chronic Myeloid Leukemia

Background: RNA interference (RNAi) is the mechanism of gene silencing-mediated messenger RNA degradation by small interference RNA (siRNA), which becomes a powerful tool for in vivo research, especially in the areas of cancer. In this research, the potential use of an expression vector as a specific siRNA producing tool for silencing of Bcr-abl in K562 cell line has been investigated. Methods:...

BCR/ABL mRNA and the P210(BCR/ABL) protein are downmodulated by interferon-alpha in chronic myeloid leukemia patients.

The BCR/ABL hybrid gene plays a central role in the pathogenesis of the chronic phase of chronic myeloid leukemia (CML). We used a very sensitive quantitative reverse transcriptase-polymerase chain reaction to investigate the levels of hybrid BCR/ABL mRNA in bone marrow cells of 20 patients with Philadelphia positive (Ph(+)) CML treated with interferon-alpha (IFN-alpha) as a single agent. Bone ...
