TY - JOUR. T1 - Up-regulation of soluble Axl and Mer receptor tyrosine kinases negatively correlates with Gas6 in established multiple sclerosis lesions. AU - Weinger, Jason G.. AU - Omari, Kakuri M.. AU - Marsden, Kurt. AU - Raine, Cedric S.. AU - Shafit-Zagardo, Bridget. PY - 2009/7. Y1 - 2009/7. N2 - Multiple sclerosis is a disease that is characterized by inflammation, demyelination, and axonal damage; it ultimately forms gliotic scars and lesions that severely compromise the function of the central nervous system. Evidence has shown previously that altered growth factor receptor signaling contributes to lesion formation, impedes recovery, and plays a role in disease progression. Growth arrest-specific protein 6 (Gas6), the ligand for the TAM receptor tyrosine kinase family, consisting of Tyro3, Axl, and Mer, is important for cell growth, survival, and clearance of debris. In this study, we show that levels of membrane-bound Mer (205 kd), soluble Mer (⌈150 kd), and soluble Axl (80 kd) were ...
Mer receptor tyrosine kinase (Mer) signaling plays a central role in the intrinsic inhibition of the inflammatory response to Tolllike receptor activation. Previously, we found that lung Mer protein expression decreased after lipopolysaccharide (LPS) treatment due to enhanced Mer cleavage. The purpose of the present study was to examine whether pharmacologically restored membrane-bound Mer expression upregulates the Mer signaling pathways and suppresses lung inflammatory responses. Pretreatment with the ADAM17 (a disintegrin and metalloproteinase-17) inhibitor TAPI-0 (tumor necrosis factor alpha protease inhibitor-0) reduced LPS-induced production of soluble Mer protein in bronchoalveolar lavage (BAL) fluid, restored membrane-bound Mer expression, and increased Mer activation in alveolar macrophages and lungs after LPS treatment. TAPI-0 also enhanced Mer downstream signaling, including phosphorylation of protein kinase b, focal adhesion kinase, and signal transducer and activator of ...
The RON receptor tyrosine kinase regulates epithelial cell homeostasis and tumorigenesis by transducing multiple signals through its functional domains. The present study was to determine the significance of the entire C-terminus in RON or its variant RON160-mediated activities related to cell motility and tumorigenesis. Analysis of protein phosphorylation revealed that elimination of the entire C-terminus significantly impairs the ligand-dependent or independent RON or RON160 phosphorylation and dimerization. Phosphorylation of downstream signaling proteins such as Erk1/2, AKT, and p38 MAP kinase was also diminished in cells expressing the C-terminus-free RON or RON160. These dysfunctional activities were accompanied with the inability of truncated RON or RON160 to mediate cytoplasmic β-catenin accumulation. Functional analysis further demonstrated that truncation of the C-terminus significantly impairs RON or RON160-mediated cell proliferation, morphological changes, and cellular migration.
ALK tyrosine kinase inhibition has become a mainstay in the clinical management of ALK fusion positive NSCLC patients. Although ALK mutations can reliably predict the likelihood of response to ALK tyrosine kinase inhibitors (TKIs) such as crizotinib, they cannot reliably predict response duration or intrinsic/extrinsic therapeutic resistance. To further refine the application of personalized medicine in this indication, this study aimed to identify prognostic proteomic biomarkers in ALK fusion positive NSCLC patients to crizotinib. Twenty-four patients with advanced NSCLC harboring ALK fusion were administered crizotinib in a phase IV trial which included blood sampling prior to treatment. Targeted proteomics of 327 proteins using MRM-MS was used to measure plasma levels at baseline (including pre-treatment and early treatment blood samples) and assess potential clinical association. Patients were categorized by duration of response: long-term responders [PFS ≥ 24 months (n = 7)], normal responders [3
The elevated levels of inflammatory cytokines observed in the CNS upon chronic HIV-1 infection suggest that control of the cytokine network is compromised. We have previously demonstrated that RON, which limits macrophage inflammatory activities, is reduced in brains of end-stage HIV-1-infected individuals with evidence of encephalitis (7). In this study, we have used a progressive macaque SIV CNS disease model to show that over time RON expression is decreased in SIV-infected macaques and that this inversely correlates with inflammatory cytokine expression and brain disease. Furthermore, in vitro studies using primary tissue-resident macrophages confirm that RON initially limits HIV-1 transcription, but, over the course of infection, receptor expression is decreased.. The macaque SIV infection model provided an opportunity to explore when RON expression is decreased during infection and whether this correlates with other indicators of inflammation. The macaque model has been well characterized ...

Lung cancer is the leading cause of death by cancer in North America. A decade ago, genomic rearrangements in the anaplastic lymphoma kinase (ALK) receptor tyrosine kinase were identified in a subset of non-small cell lung carcinoma (NSCLC) patients. Soon after, crizotinib, a small molecule ATP-competitive ALK inhibitor was proven to be more effective than chemotherapy in ALK-positive NSCLC patients. Crizotinib and two other ATP-competitive ALK inhibitors, ceritinib and alectinib, are approved for use as a first-line therapy in these patients, where ALK rearrangement is currently diagnosed by immunohistochemistry and in situ hybridization. The clinical success of these three ALK inhibitors has led to the development of next-generation ALK inhibitors with even greater potency and selectivity. However, patients inevitably develop resistance to ALK inhibitors leading to tumor relapse that commonly manifests in the form of brain metastasis. Several new approaches aim to overcome the various mechanisms of
Neuronal migration is a crucial process that allows neurons to reach their correct target location to allow the nervous system to function properly. AP-2α is a transcription factor essential for neural crest cell migration and its mutation results in apoptosis within this cell population, as demonstrated by genetic models. We down-modulated AP-2α expression in GN-11 neurons by RNA interference and observe reduced neuron migration following the activation of a specific genetic programme including the Adhesion Related Kinase (Axl) gene. We prove that Axl is able to coordinate migration per se and by ChIP and promoter analysis we observe that its transcription is directly driven by AP-2α via the binding to one or more functional AP-2α binding sites present in its regulatory region. Analysis of migration in AP-2α null mouse embryo fibroblasts also reveals an essential role for AP-2α in cell movement via the activation of a distinct genetic programme. We show that AP-2α plays an essential role in cell
Graduate Student. Receptor tyrosine kinase RON, besides being expressed on tumor cells is also expressed on host macrophages and epithelial cells. My project is focused on deciphering the role of Ron (receptor tyrosine kinase) expressing resident peritoneal macrophages in breast cancer metastasis. I am using immune competent in vivo mouse models to address this question. I am also interested in delineating the developmental origin of Ron expressing resident peritoneal macrophages. Contrary to the previously well-established dogma that all macrophages originate from bone marrow derived monocytes recent studies has shown embryonic origins of certain tissue resident macrophages. I am using in vivo lineage tracing models to address this question. And outside of the lab, I love kayaking. ...

Cirrhosis of the liver is a condition with a high mortality and raising prevalence worldwide. Infectious complications are highly frequent and independent predictors of outcome in patients with cirrhosis - being the leading cause of decompensation, acute-on-chronic liver failure (ACLF) and death. There is no treatment option other than transplantation, applicable at early stages and to only a minority of patients. Susceptibility to infection has been documented in patients with cirrhosis and has been attributed to immuneparesis and monocyte dysfunction in the state of decompensation and liver failure. The underlying mechanisms are incompletely understood. Development of targeted immunomodulatory strategies might effectively reduce infectious complications and mortality in cirrhosis. MER receptor tyrosine kinase (MERTK), expressed on monocytes/macrophages, plays a pivotal role in dampening innate immune responses. We have recently discovered and documented the role of MERTK in innate immune ...
In general, tumors exhibit higher tyrosine kinase activity in comparison to normal tissues. This correlation is also reflective in tumor cells versus normal epithelial cells. Receptor tyrosine kinases modulate diverse processes involved in tumor progression and metastasis. Consequently, receptor tyrosine kinases are viewed as attractive targets for molecular therapy. An understanding of the molecular alterations that facilitate tumor progression and metastasis will provide insight into approaches to optimize targeted therapies. In this context, the role of the receptor tyrosine kinase RON in human epithelial cell malignancies is currently under active investigation. We have recently shown that the RON ligand, MSP, promotes the invasive phenotype of MDA-MB-231 and MDA-MB-468 cells and also identified the critical regulatory elements that are required for basal RON promoter activity and RON gene expression ( 24). We have followed up those studies in this article and showed that a chemopreventive ...
Describes how Anaplastic Lymphoma Receptor Tyrosine Kinase (ALK) mutation testing is used, when ALK mutation (gene rearrangement) testing is ordered, and what the results of ALK mutation testing might mean
The management of anaplastic lymphoma kinase rearranged (ALK+) non-small cell lung cancer (NSCLC) exemplifies the potential of a highlights the success of the precision medicine approach to cancer careparadigm. The ALK inhibitor crizotinib has demonstrated led to improved outcomes in the first and second line setting, however, toxicities, intracranial activity and acquired resistance necessitated the advent of later generation ALK inhibitors. A large portion of acquired resistance to ALK inhibitors is caused by secondary mutations in the ALK kinase domain. Alectinib is a second generation ALK inhibitor capable of overcoming multiple crizotinib resistant ALK mutations and has demonstrated improved outcomes after crizotinib failure, leading to approval in crizotinib treated ALK+ NSCLC patients. Favorable toxicity profile and improved intracranial activity haves spurred ongoing front line trials and comparisons to other ALK inhibitors. However, important questions regarding comparability to competitor
p,This chapter presents a general approach for the application of spatial intensity distribution analysis (SpIDA) to the pharmacodynamic quantification of receptor tyrosine kinase homodimerization in response to direct ligand activation or transactivation by G-protein-coupled receptors. Intensity histograms are generated from single fluorescence microscopy images. These histograms are then fit with Poissonian distributions to obtain density maps and quantal brightness values of the labeled proteins underlying the images. This approach allows resolving monomer/oligomer protein mixtures within subcellular compartments using conventional confocal laser scanning microscopy. The application of quantitative pharmacological analysis to data obtained using SpIDA provides a universal method for comparing studies between cell lines and receptor systems. In contrast to methods based on resonance energy transfer, SpIDA is suitable not only for use in recombinant systems but also for the characterization of ...

Oncogenic fusions of anaplastic lymphoma kinase (ALK) define a subset of human lung adenocarcinoma. The 1st generation ALK inhibitor crizotinib demonstrated impressive clinical benefit in ALK-fusion positive lung cancers and was approved by the FDA for the treatment of ALK-fusion positive NSCLC in 2011. However, as seen with most kinase inhibitors, patients treated with crizotinib eventually develop resistance to therapy. Acquired ALK kinase domain mutations and disease progression in the central nervous system (CNS) are reported as main contributors to patient relapse after ALK inhibitor therapy. Preclinically, crizotinib lacks significant brain penetration and does not potently inhibit activity of ALK kinase domain mutants, so a drug discovery program was initiated aimed to develop a second generation ALK inhibitor that is more potent than existing ALK inhibitors, capable of inhibiting the resistant ALK mutants and penetrating the blood-brain-barrier. These objectives present a considerable ...

N2 - Targeted therapies that inhibit receptor tyrosine kinases (RTKs) and the downstream phosphatidylinositol 3-kinase (PI3K) signaling pathway have shown promising anticancer activity, but their efficacy in the brain tumor glioblastoma multiforme (GBM) and other solid tumors has been modest. We hypothesized that multiple RTKs are coactivated in these tumors and that redundant inputs drive and maintain downstream signaling, thereby limiting the efficacy of therapies targeting single RTKs. Tumor cell lines, xenotransplants, and primary tumors indeed show multiple ...

Drug resistance remains an elusive problem in cancer therapy, particularly with novel targeted therapy approaches. Much work is currently focused upon the development of an increasing arsenal of targeted therapies, towards oncogenic driver genes such as ALK-EML4, to overcome the inevitable resistance that develops as therapies are continued over time. The current clinical paradigm after failure of first line ALK TKI is to administer another drug in the same class. As to which drug however, the answer is uncertain, as clinical evidence is lacking. To address this shortcoming, we evolved resistance in an ALK rearranged non-small cell lung cancer line (H3122) to a panel of 4 ALK tyrosine kinase inhibitors used in clinic, and performed a collateral sensitivity analysis to each of the other drugs. We found that all of the ALK inhibitor resistant cell lines displayed a significant cross-resistance to all other ALK inhibitors. To test for the stability of the resistance phenotypes, we evaluated the ...

Ensartinib, also known as X-396, is an orally available small molecule inhibitor of the receptor tyrosine kinase anaplastic lymphoma kinase (ALK) with potential antineoplastic activity. Upon oral administration, X-396 binds to and inhibits ALK kinase, ALK fusion proteins and ALK point mutation variants. Inhibition of ALK leads to the disruption of ALK-mediated signaling and eventually inhibits tumor cell growth in ALK-expressing tumor cells. ALK belongs to the insulin receptor superfamily and plays an important role in nervous system development.
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene is a member of the echinoderm microtubule associated protein-like family. The encoded WD-repeat protein may be involved in microtubule formation. Abnormal fusion of parts of this gene with portions of the anaplastic lymphoma receptor tyrosine kinase gene, which generates EML4-ALK fusion transcripts, is one of the primary mutations associated with non-small cell lung cancer. Alternative splicing of this gene results in two transcript variants. [provided by RefSeq, Jan 2015 ...

Greg Lemke discovered a family of three receptor tyrosine kinases, called TAM receptors, which play a crucial role in telling immune cells how to handle infection from bacteria, viruses and other pathogens, as well as normal cellular debris. His lab showed how problems with the TAM receptors (called Axl, Mer and Tyro3) or their pathways are associated with increased levels of drug-resistant cancer as well as inflammation and autoimmune disease. Understanding how to separate the roles of each receptor could lead to new classes of drugs to fight viruses and bacteria. Aside from immune function, TAM receptors are involved in the healthy development of the nervous system. Lemke also focuses on another major family of receptor tyrosine kinases, called Eph receptors. These are one of the earliest to show up in the developing brain of a fetus and help to guide neuronal connections. Eph receptors help neurons-like those that link the eyes to the brain-know where to go as they grow.. ...
Mice homozygous for the Axl knockout allele exhibit an overtly normal phenotype - however, in combination with mutations in other receptor tyrosine kinases, this strain may be useful in studies of innate immunity, autoimmunity, germ cell development and apoptosis. Axl is highly expressed by key cellular targets of ZIKA virus (ZIKV), and is proposed to promote viral entry in certain cell types (including non-Axl-expressing cells). Axl inhibition represents a potential approach for antiviral therapies.

Author Summary The need to achieve precise control of RTK activation is highlighted by human pathologies such as congenital malformations and cancers caused by aberrant RTK signalling. Identifying strategies to restrain RTK activity in cancer and/or to reactivate RTKs for counteracting degenerative processes is the focus of intense research efforts. We designed a genetic system to enhance RTK signalling during mouse embryogenesis in order to examine the competence of cells to deal with changes in RTK inputs. Our data reveal that most embryonic cells are capable of: 1) handling moderate perturbations in Met-RTK expression levels, 2) imposing a threshold of intracellular signalling activation despite elevated Met-RTK inputs, and/or 3) integrating variable quantitative levels of Met-RTK signalling within biological responses. Our results also establish that certain cell types, such as limb mesenchyme, are particularly vulnerable to alterations of the spatial distribution of RTK expression. The
