Des réarrangements chromosomiques impliquant le domaine kinase d’ALK sont présents dans environ 3 à 6% des patients atteints d'un adénocarcinome bronchique.

Abstract:
Chronic Myeloid Leukemia (CML) is a chronic myeloproliferative neoplasm derived from the neoplastic transformation of the pluripotent stem cell characterized by the reciprocal translocation between chromosome 9 (9q) and 22 (22q) t (9; 22) (q34; q11), which leads to the formation of a new BCR-ABL1 gene that causes expansion of the pathological clone. The introduction of tyrosine kinase inhibitor drugs (TKIs) has revolutionized the treatment of this neoplasm. However, about a third of patients have to suspend treatment for resistance or intolerance to TKIs. The aim of our study was to identify t

Abstract:
As the prevalence of Chronic Myeloid Leukaemia (CML) grows, due to the therapeutic success of tyrosine kinase inhibitors (TKI), we are witnessing increased incidences of drug resistance. Some of these patients have failed all currently licensed TKIs and have no mutational changes in the kinase domain that may explain the cause of TKI resistance. This poses a major clinical challenge as there are currently no other drug treatment options available for these patients. Therefore, our aim was to identify and target alternative survival pathways against BCR-ABL in order to eradicate TKI-resistant c

The anaplastic lymphoma kinase (ALK) protein drives tumorigenesis in subsets of several tumors through chromosomal rearrangements that express and activate its C-terminal kinase domain.

ALK-specific tyrosine kinase inhibitors (TKIs) have become important new drugs for ALK-driven lung cancer, but acquired resistance via multiple mechanisms including kinase-domain mutations eventually develops, limiting median progression-free survival to less than a year

Resistance to therapeutic drugs is detrimental to treatment efficacy in chronic myeloid leukaemia (CML).

However, therapeutic TKI resistance often results in suboptimal treatment response.

Chronic Myelogenous Leukemia (CML) is a blood cancer that arises when hematopoietic cells acquire an abnormal protein known as BCR-ABL. Current therapies for CML include drugs that inhibit BCR-ABL.

One reason is that BCR-ABL drugs fail to kill the primitive population of CML cells, referred to as leukemia stem cells (LSCs), which are responsible for initiating and propagating CML. Since LSCs are not killed, the cancer is not cured and many affected patients eventually relapse. Recent studies suggest that LSCs are protected from
