Anaplastic Lymphoma Kinase (ALK) is a transmembrane receptor kinase that belongs to the insulin receptor superfamily and has previously been shown to play a role in cell proliferation, migration and invasion in neuroblastoma. Activating ALK mutations are reported in both hereditary and sporadic neuroblastoma tumours, and several ALK inhibitors are currently under clinical evaluation as novel tr...
UNLABELLED Activated anaplastic lymphoma kinase (ALK) and ROS1 tyrosine kinases, through gene fusions, have been found in lung adenocarcinomas and are highly sensitive to selective kinase inhibitors. This study aimed at identifying the presence of these rearrangements in human colorectal adenocarcinoma specimens using a 4-target, 4-color break-apart FISH assay to simultaneously determine the ge...
Crizotinib (PF02341066) is a tyrosine kinase inhibitor of anaplastic lymphoma kinase (ALK) that has been shown to selectively inhibit growth of cancer cells that harbor the EML4-ALK fusion found in a subset of patients with non-small cell lung cancer (NSCLC). While in clinical trials, PF02341066 has shown a significant therapeutic benefit as a single agent; the effectiveness of combining it wit...
Summary This year’s virtual version of the European Society for Medical Oncology (ESMO) presidential sessions included three “late breaking” non-small cell lung cancer (NSCLC) abstracts, discussing strategies adjuvant therapy localized disease and up-front treatment advanced anaplastic lymphoma kinase(ALK)-positive cancer.
Genetic rearrangements of the anaplastic lymphoma kinase (ALK) kinase occur in 3% to 13% of non-small cell lung cancer patients and rarely coexist with KRASor EGFR mutations. To evaluate potential treatment strategies for lung cancers driven by an activated EML4-ALK chimeric oncogene, we generated a genetically engineered mouse model that phenocopies the human disease where this rearranged gene...
Targeting of essential growth drivers represents an ideal approach to cancer treatment. To identify such molecules in clinical specimens, we developed a highly sensitive functional screening system based on the preparation of retroviral cDNA expression libraries. By screening such a library of lung adenocarcinoma with a focus formation assay, we discovered the EML4-ALK fusion-type oncogene. A s...
The co-occurrence of epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) rearrangements constitutes a rare molecular subtype of non-small-cell lung cancer (NSCLC). Herein, we assessed the clinical outcomes and incidence of acquired resistance to tyrosine kinase inhibitors (TKIs) in this subtype. So we enrolled 118 advanced NSCLC treated with TKIs. EGFR mutatio...
A specific subtype of non-small-cell lung cancer (NSCLC) characterized with an EML4-ALK fusion gene, which drives constitutive oncogenic activation of anaplastic lymphoma kinase (ALK), shows a good clinical response to ALK inhibitors. We have reported multiple examples implying the biological significance of methylation on non-histone proteins including oncogenic kinases in human carcinogenesis...
Human anaplastic lymphoma kinase (ALK) has been identified as an oncogene that is mutated or amplified in NBLs. To obtain a better understanding of the molecular events associated with ALK in the pathogenesis of NBL, it is necessary to clarify how ALK gene contributes to NBL progression. In the present study, we found that ALK expression was significantly high in NBL clinical samples with ampli...
A subset of non-small cell lung cancer (NSCLC) tumors (5%) harbors an anaplastic lymphoma kinase (ALK) translocation that drives tumorigenesis. The clinically approved first-line treatment crizotinib specifically inhibits ALK and improves progression-free survival (PFS) in treated and untreated patients by 4 months compared to standard chemotherapy. While some patients relapse after crizotinib ...
