Deregulation of the sonic hedgehog (SHH) signaling pathway has been implicated in several cancers but has not been explored in T-cell lymphomas. Here, we report that the SHH/GLI1 signaling pathway is activated in anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALCL). We show that SHH, but not its transcriptional effector GLI1, is amplified in ALK+ ALCL tumors and cell ...
Numerous mutations have been observed in the Anaplastic Lymphoma Kinase (ALK) receptor tyrosine kinase (RTK) in both germline and sporadic neuroblastoma. Here, we have investigated the Y1278S mutation, observed in four patient cases, and its potential importance in the activation of the full length ALK receptor. Y1278S is located in the 1278-YRASYY-1283 motif of the ALK activation loop, which h...
Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase essentially and transiently expressed in specific areas of the developing central and peripheral nervous systems. We previously demonstrated that a membrane-bound and constitutively active form of the ALK protein tyrosine kinase (PTK) domain induced the neuron-like differentiation of PC12 cells through specific activation of the mit...
Anaplastic lymphoma kinase (ALK) is a receptor-type protein tyrosine kinase that is expressed preferentially in neurons of the central and peripheral nervous systems at late embryonic stages. To elucidate the role of ALK in neurons, we developed an agonist monoclonal antibody (mAb) against the extracellular domain of ALK. Here we show that mAb16-39 elicits tyrosine phosphorylation of endogenous...
Anaplastic lymphoma kinase (ALK) is a receptor-type protein tyrosine kinase that is currently the focus of much attention in oncology. ALK is rendered oncogenic as a result of its fusion to NPM1 in anaplastic large cell lymphoma, to TPM3 or TPM4 in inflammatory myofibroblastic tumor, to EML4 in non-small cell lung carcinoma, and to VCL in renal medullary carcinoma. It is also activated as a res...
The discovery of anaplastic lymphoma kinase (ALK) gene rearrangements and the development of tyrosine kinase inhibitors (TKI) that target them have achieved unprecedented success in the management of patients with ALK-positive non-small cell lung cancer (NSCLC). Despite the high efficacy of crizotinib, the first oral ALK TKI approved for the treatment of ALK-positive NSCLC, almost all patients ...
Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKI), including crizotinib, are effective treatments in preclinical models and in cancer patients with ALK-translocated cancers. However, their efficacy will ultimately be limited by the development of acquired drug resistance. Here we report two mechanisms of ALK TKI resistance identified from a crizotinib-treated non-small cell lung...
BNP7787 (Tavocept, disodium 2,2'-dithio-bis-ethanesulfonate) is a novel, investigational, water-soluble disulfide that is well-tolerated and nontoxic. In separate randomized multicenter Phase II and Phase III clinical trials in non-small-cell lung cancer (NSCLC) patients, treatment with BNP7787 in combination with standard chemotherapy resulted in substantial increases in the overall survival o...
2015 Targeted therapies based on molecular diagnostics have opened a new era of personalized medicine in lung cancer treatment. Recently, anaplastic lymphoma kinase (ALK) fusion gene emerged as an important biomarker for identifying a small proportion of non-small-cell lung cancer (NSCLC) patients that will benefit from ALK kinase inhibitor crizotinib, like EGFR activating mutations and EGFR ty...
The discovery of an echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) fusion gene led to improved clinical outcomes in patients with lung cancer after the development of the first ALK-targeting agent, crizotinib. Some second-generation ALK tyrosine kinase inhibitors (TKIs), which might be more potent than crizotinib or effective on crizotinib-resistant pat...
