The treatment of chronic myeloid leukaemia (CML) requires quantitative polymerase chain reaction (qPCR) to monitor BCR-ABL1 in International Scale (IS).
Chronic myelogenous leukemia (CML) is a myeloproliferative disorder defined by the presence of the fusion gene BCR-ABL1 in primitive hematopoietic progenitors.
Chronic myelogenous leukemia (CML) is caused by the BCR-ABL chimeric tyrosine kinase, which is derived from the reciprocal translocation, t(9;22)(q34;q11).
It remains unknown whether the administration of tyrosine kinase inhibitors (TKIs) targeting BCR-ABL1 after allogeneic hematopoietic cell transplantation (HCT) is associated with improved outcomes for patients with chronic myelogenous leukemia (CML).
Asciminib is a potent, specific BCR-ABL1 inhibitor being developed for the treatment of patients with chronic myelogenous leukemia (CML) and Philadelphia chromosome positive acute lymphoblastic leukemia (Ph + ALL).
In conclusion, HHT induced p62‑mediated autophagy in imatinib‑resistant CML K562G cells, thus promoting autophagic degradation of the BCR‑ABL protein and providing a novel strategy for the treatment of TKI‑resistant CML.
This observation prompted us to explore anti-leukemic effects of the combination dasatinib + bosutinib in highly resistant primary CML cells, various CML cell lines (K562, K562R, KU812, KCL22) and Ba/F3 cells harboring various BCR-ABL1 mutant-forms.
A reduction in <i>BCR-ABL1/ABL1<sup>IS</sup></i> transcript levels to <10% after 3 months or <1% after 6 months of tyrosine kinase inhibitor therapy are associated with superior clinical outcomes in chronic myeloid leukemia (CML) patients.
BCR-ABL1-negative myeloproliferative disorders and chronic myeloid leukaemia are haematologic malignancies characterised by single and mutually exclusive genetic alterations.
Subsequent to the development and global availability of BCR/ABL-targeted tyrosine kinase inhibitors (TKIs), the prognosis of patients with chronic myeloid leukemia (CML), at least those in the chronic phase, has markedly improved, and in the developed world, the average lifespan of these patients is now close to that of age- and sex-matched subjects without the disease.
This includes the use asciminib as first in class inhibitor targeting the myristoyl pocket of BCR-ABL, combination treatments with established non-TKI drugs such as interferon and drugs with novel targets relevant to CML biology such as gliptins and thiazolidinediones.
The Janus kinase 2 (<i>JAK2</i>) V617F mutation is common in patients with breakpoint cluster region-Abelson1 (<i>BCR-ABL1</i>)-negative myeloproliferative neoplasms, including polycythemia vera, essential thrombocythemia and primary myelofibrosis, but is rarely detected in <i>BCR-ABL1-</i>positive chronic myeloid leukemia (CML) patients.
Dasatinib, a second-generation BCR-ABL1 tyrosine kinase inhibitor, is approved for the treatment of chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia, both as first-line therapy and after imatinib intolerance or resistance.
It would be a useful pharmacological tool to study the TKI resistant ABLV299L mutant-mediated pathology and provide a potential precise treatment approach for this orphan CML subtype in the precision medicine era.
Naked BCR-ABL-targeting ADO was significantly more potent than siRNA at reducing BCR-ABL chimeric mRNA expression in chronic myeloid leukemia (CML) cell lines.
However, due to primary resistance or secondary resistance caused by mutations in the BCR-ABL1 kinase domain, TKIs cannot completely prevent the progression of CML; thus, the study of BCR-ABL1 gene expression regulation is of great significance.
