The dysregulation of miRNA expression patterns is one of the many effects developments of cancer, miRNA has been found to express abnormally in hematological neoplasia such as chronic myeloid leukemia and solid malignancies. Resistance and the degree of response following tyrosine kinase inhibitor treatment are correlated with miRNA expression. Hence, in this study we tried to study the relationship of miRNA-150 between different breakpoint cluster region–Abelson (BCR- ABL) P210 transcript levels and the role miRNA- 150 between different levels of imatinib optimal response in chronic myeloid leukemia (CML). Our study included sixty chronic myeloid leukemia (CML) patients they were divided into two groups based on response to imatinib therapy, thirty samples of the optimal molecular response of chronic myeloid leukemia (CML) patients, and thirty samples of failure molecular response chronic myeloid leukemia (CML) patients. Thirty samples of apparently healthy volunteers were included and evaluated as control. According to the P210 BCR-ABL%, the results showed a significant difference (P= < 0.0001) between the responder and the failure response CML patients. Assessed the result of miRNA-150 showed a significant difference between both CML patients (P = < 0.0001), assessed miRNA-150 level among different response groups, and failure response of CML patients (P = 0.0002). A cutoff value of response vs. failure response (1.784) with high sensitivity can be a diagnostic value to differentiate between response and failure response. Changing gene expression with different amounts of miRNAs had an impact on drug-gene interactions, with consequences for cell growth and death. Gene expression of different levels miRNA-150 among of CML patients of imatinib therapy showed high expression in response patients than failure response patients. The gene expression level of miRNA-150 differs through different responses in CML patients.
