Acute lymphoblastic leukemia (ALL) with BCR-ABL1 translocation is an aggressive malignancy that is usually treated with intensive chemotherapy with the possibility of allogeneic stem cell transplantation.
Also highlighted are the functional consequences of aberrant splice variants (<i>BCR-Abl35INS</i>, <i>BIM-γ</i>, <i>IK6</i>, <i>p61 BRAF V600E</i>, <i>CD19-∆2</i>, <i>AR-V7</i> and <i>PIK3CD-S</i>) in promoting resistance to cancer targeted therapy or immunotherapy.
Among 1718 allo-HSCT, 74% were performed for malignancy (ALL 47.2%, AML 26.2%, MDS 10.8%, CML 8.1%, NHL/HD 6.1%, others 2.5%), and 26% for non-malignant disorders (SAA 41%, congenital immunodeficiencies 35.4%, hereditary bone marrow failure 16%, metabolic disorders 7%).
At current work, the combination of sensors were used to detect the presence of BCR-ABL1 as a mutant gene and CEA as a biomarkers of cancer, such a capability makes the package liable for early and certain detection of acute lymphoblastic leukemia.
Chronic myeloid leukemia (CML) is a hematopoietic stem cell malignancy characterized by the expression of the BCR-ABL1 fusion gene with different chimeric transcripts.
Here we present proof-of-principle experiments showing how a conditional transgenic mouse model of BCR-ABLp190-driven B-ALL offers the opportunity to test the hypothesis that the age of the leukemic cells-of-origin of B-ALL influences B-ALL malignancy.
In CML, the BCR-ABL1 fusion gene and its companion messenger RNA offers a unique target differentiating cancer from the normal cell, affording the potential for very sensitive and specific assays.
In this issue of Cancer Discovery, Geng and colleagues report on their use of a combination of promoter cytosine methylation profiling with gene expression and ChIP sequencing to elucidate molecular signatures of adult B-acute lymphoblastic leukemia patient samples with BCR-ABL1, E2A-PBX1, and MLL rearrangements.
Increasing sophisticated information suggests that cancer cells express constitutively active oncogenic kinases such as breakpoint cluster region- c-abl oncogene 1, non-receptor tyrosine kinase (BCR-ABL1) that promote carcinogenesis independent of extrinsic growth factors.
Novel FISH probes designed to detect IGK-MYC and IGL-MYC rearrangements in B-cell lineage malignancy identify a new breakpoint cluster region designated BVR2.
The extraordinary success of imatinib in the treatment of BCR-ABL1 associated cancers underscores the need to identify novel functional gene fusions in cancer.
The first clear cut association of an oncogene with a specific cancer is the c-abl translocation in chronic myelogenous leukemia and acute lymphocytic leukemia; it has been observed in 90% of CML cases examined.
