The epidermal growth factor (EGF) and its receptor (EGFR) constitute a well-characterized receptor-ligand system that plays an important role in the regulation of cell growth, proliferation, survival, and motility (1-4). EGFR is involved in oncogenic transformation, which can be caused by receptor overexpression, autocrine ligand loops, gene amplification, or activating mutations such as the EGFR type III deletion mutant (EGFRvIII; refs. 5-8).. In a global search for EGFR and EGFRvIII regulated genes, we recently found the mRNA level of the receptor tyrosine kinase EphA2 to be up-regulated by ligand-activated EGFR and the constitutively active variant EGFRvIII (9).. The cDNA sequence of EphA2 (previously known as epithelial cell kinase) was first described by Lindberg and Hunter in 1990 (10). EphA2 belongs to the Eph receptor family, which is the largest subfamily of receptor tyrosine kinases (11). Based on similarities in the extracellular domain sequences, the Eph receptors are divided into ...

2364 Lung cancer is the leading cause of cancer deaths worldwide. The development of improved systemic therapy is needed for those with the most common form of the disease, non-small cell lung cancer (NSCLC). This will depend on the identification of valid molecular targets. Recent studies point to the receptor tyrosine kinase EphA2 as a novel therapeutic target. EphA2 is commonly expressed in tumor tissue from patients with NSCLC, and its expression correlates with poor prognosis. However, these studies have only been carried out on a small number of patient samples. A more comprehensive assessment of EphA2 expression in NSCLC is currently needed. EphA2 may be particularly relevant in cancers with K-Ras mutations, which confer resistance to epidermal growth factor receptor (EGFR) therapy. RAS mutation leads to increased EphA2 expression in vitro. RAS-RAF-MAPK pathway activation via RAS mutation or EGFR activation is common in NSCLC. EphA2 has also been implicated in tumor angiogenesis, and ...

Purpose: : EphA receptors and ephrinA ligands are involved in nerve and vessel guidance during development, vascular cell assembly, and angiogenesis. Soluble ephrinA1-Fc has been reported to possess proangiogenic properties. Our purpose was to investigate the expression patterns of EphA and ephrinA in the cornea and in cultured mouse corneal cells. Methods: : SV40 T antigen-immortalized mouse corneal epithelial and keratocyte cell lines were generated and characterized using epithelial-/and keratocyte-specific markers. Confocal immunohistochemistry using antibodies against ephrinA ligands (ephrinA1, A2, A3, A4, or A5) and EphA receptors (EphA1, A2, A3, A4, A5, A6, A7, or A8) were used in vitro (immortalized wild type mouse corneal epithelial cells and keratocytes) and in vivo (normal mouse cornea). Results: : EphrinA1 and EphA3 were expressed mainly in normal mouse corneal epithelium. EphA1, A2, and A3 and ephrinA1 and A2 were expressed in corneal epithelial cell lines. EphA3 and ephrinA2 showed ...

Catalytic domain of the Protein Tyrosine Kinases, Class EphA Ephrin Receptors. Protein Tyrosine Kinase (PTK) family; Ephrin Receptor (EphR) subfamily; most class EphA receptors including EphA3, EphA4, EphA5, and EphA7, but excluding EphA1, EphA2 and EphA10; catalytic (c) domain. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. EphRs comprise the largest subfamily of receptor tyr kinases (RTKs). In general, class EphA receptors bind GPI-anchored ephrin-A ligands. There are ten vertebrate EphA receptors (EphA1-10), which display promiscuous interactions with six ephrin-A ligands. One exception is EphA4, which also binds ephrins-B2/B3. EphRs contain an ephrin-binding domain and two fibronectin repeats extracellularly, a transmembrane segment, ...

EphA2 kinase regulates cell shape, adhesion, and motility and is frequently overexpressed in several cancers, including melanoma, prostate, breast, and colon cancers and lung carcinoma. Although a function in both tumor onset and metastasis has been proposed, the role played by EphA2 in tumor progression is still debated. In melanoma, EphA2 has been reported to affect cell migration and invasiveness allowing cells to move by a proteolysis-independent strategy, commonly referred as amoeboid motility. With the aim to understand the role of EphA2 in prostate cancer metastatic spreading, we stably silenced EphA2 expression in a model of aggressive metastatic prostate carcinoma. Our results show that EphA2 drives the metastatic program of prostate carcinoma, although its involvement greatly differs among metastatic steps. Indeed, EphA2 expression (i) greatly affects prostate carcinoma cell motility style, guiding an amoeboid movement based on Rho-mediated cell rounding and independent from ...

Recent efforts in analyzing cancer genome have identified EPHA2 as one of the genes that are elevated in human lung cancer, and high levels of EPHA2 are associated with poor clinical outcomes. However, mechanistic basis for EPHA2 in lung cancer promotion remains poorly understood. In this study, we found that EPHA2 regulates tumor cell proliferation and motility through the JNK-c-JUN pathway. In addition, we provide evidence that EPHA2 is important for CSC function. Collectively, these data identified JNK/c-JUN as a major signaling pathway that is activated by oncogenic EPHA2 receptor in NSCLC, and a critical role for EPHA2 in CSCs.. Multiple intracellular signaling pathways have been linked to EPHA2 receptor in cancer cells (reviewed in refs. 2, 25). Ligand stimulation of EPHA2 has been shown to inhibit ERK and AKT phosphorylation, and tumor cell proliferation and motility in prostate and lung cancer cells, as well as in malignant glioma cells (11, 26, 27). Conversely, ligand-independent EPHA2 ...

The major finding of our present study is that the EphA2 receptor tyrosine kinase is overexpressed in many ovarian cancers. We also showed that EphA2 overexpression relates to disease grade and survival and in particular, that EphA2 may provide independent information to guide evaluations of clinical outcome.. Our work breaks new ground in linking EphA2 with ovarian cancer. These results are consistent with studies of other epithelial carcinomas, in which EphA2 is not phosphorylated and has been described as an oncoprotein that critically controls tumor cell growth, survival, migration, invasiveness, and angiogenesis (5 , 20, 21, 22, 23, 24) . Overexpression of EphA2 has been noted in multiple epithelial carcinomas, including breast, melanoma, prostate, non-small-cell lung, and esophageal cancers (17, 18, 19, 20, 21) . To the best of our knowledge, our study is the first to evaluate the role of EphA2 in ovarian carcinoma, and its overexpression is predictive of aggressive ovarian cancer ...

EphA2, a member of Eph family receptor tyrosine kinases, is frequently overexpressed in a variety of human cancers, including breast cancers (Merlos-Suárez and Batlle, 2008; Pasquale, 2008). Overexpression of EphA2 is associated with an aggressive and metastatic cellular phenotype in breast cancers, and recent studies have revealed that EphA2 acts as a downstream effector of EGF receptors to promote cancer cell motility and invasion, independently of the ligand ephrin stimulation (Zelinski et al., 2001; Macrae et al., 2005; Larsen et al., 2007; Brantley-Sieders et al., 2008; Miao et al., 2009). Conversely, stimulation of EphA2 with its ligand ephrinA1 in cancer cells inhibits cell proliferation and migration (Miao et al., 2009). However, the mechanisms underlying the oncogenic effects of EphA2 remain poorly understood.. Rho family small GTPases play pivotal roles in the regulation of the actin cytoskeleton and cell migration and also contribute to many steps in cancer initiation and progression ...

The EphA4 receptor tyrosine kinase is a major regulator of axonal growth and astrocyte reactivity and is a possible inflammatory mediator. Given that multiple sclerosis (MS) is primarily an inflammatory demyelinating disease and in mouse models of MS, such as experimental autoimmune encephalomyelitis (EAE), axonal degeneration and reactive gliosis are prominent clinical features, we hypothesised that endogenous EphA4 could play a role in modulating EAE. EAE was induced in EphA4 knockout and wildtype mice using MOG peptide immunisation and clinical severity and histological features of the disease were then compared in lumbar spinal cord sections. EphA4 knockout mice exhibited a markedly less severe clinical course than wildtype mice, with a lower maximum disease grade and a slightly later onset of clinical symptoms. Numbers of infiltrating T cells and macrophages, the number and size of the lesions, and the extent of astrocytic gliosis were similar in both genotypes; however, EphA4 knockout mice ...

N2 - Age-related cataract is the major cause of blindness worldwide. Both genetic and environmental factors contribute to the disease. Genetic variation in the Ephrin type-A receptor 2 (EPHA2) gene is associated with the risk of age-related cataract in multiple populations, and exposure to ultraviolet-B (UV-B) radiation is a well-established risk factor for the disease. Epha2 knockout and UV-B radiation independently lead to cataract in mice, and UV-B radiation reportedly alters EPHA2 expression in cultured cells. We hypothesised that an interaction between UV-B radiation exposure and Epha2 signalling may influence cataract development. To test this hypothesis, ...

The gene encoding the mouse EphA8 receptor tyrosine kinase has been isolated from a mouse genomic library, and its complete genomic structure has been determined. This gene spans approximately 28 kb and consists of 17 exons. This gene structure is similar to the structure of the chick EphB2(Cek5) gene, except for one intron present between the first two exons encoding the EphA8 kinase domain. This difference may reflect an evolutionary divergence of the catalytic domain between EphA and EphB subgroup receptors. The site for transcription initiation has been mapped to the 19th nucleotide upstream from the translation start codon ATG. A feature of this gene is an unmethylated CpG island spanning exon 1 and the flanking sequence. The putative promoter of the EphA8 gene lacks a TATA box and contains multiple copies of the sequence GGGCGG, the core sequence of the putative Sp1-binding site. The 3.5-kb upstream genomic region containing part of the first exon showed strong promoter activity in ...

Resistance to immunotherapy is one of the biggest problems of current oncotherapeutics. While T cell abundance is essential for tumor responsiveness to immunotherapy, factors that define the T cell-inflamed tumor microenvironment are not fully understood. We used an unbiased approach to identify tumor-intrinsic mechanisms shaping the immune tumor microenvironment (TME), focusing on pancreatic adenocarcinoma because it is refractory to immunotherapy and excludes T cells from the TME. From human tumors, we identified ephrin-A receptor 2 (EPHA2) as a candidate tumor-intrinsic driver of immunosuppression. Epha2 deletion reversed T cell exclusion and sensitized tumors to immunotherapy. We found that prostaglandin endoperoxide synthase 2 (PTGS2), the gene encoding cyclooxygenase-2, lies downstream of EPHA2 signaling through TGF-β and is associated with poor patient survival. Ptgs2 deletion reversed T cell exclusion and sensitized tumors to immunotherapy; pharmacological inhibition of PTGS2 was ...

The 1C1-mcMMAF immunoconjugate specifically bound to EphA2-positive HeyA8 cells but not to EphA2-negative cells and was internalized by HeyA8 cells. Treatment with 1C1-mcMMAF decreased the viability of HeyA8-luc cells in an EphA2-specific manner. In orthotopic mouse models, treatment with 1C1-mcMMAF inhibited tumor growth by 85%-98% compared with that in control mice (eg, for weight of HeyA8 tumors, 1C1-mcMMAF = 0.05 g and control = 1.03 g; difference = 0.98 g, 95% confidence interval [CI] = 0.40 to 1.58 g; P = .001). Even in bulkier disease models with HeyA8-luc cells, 1C1-mcMMAF treatment, compared with control treatment, caused regression of established tumors and increased survival of the mice (eg, 1C1-mcMMAF vs control, mean = 60.6 days vs 29.4 days; difference = 31.2 days, 95% CI = 27.6 to 31.2 days; P = .001). The antitumor effects of 1C1-mcMMAF therapy, in SKOV3ip1 tumors, for example, were statistically significantly related to decreased proliferation (eg, 1C1-mcMMAF vs control, mean = ...

Alzheimers disease is an age-dependent neurodegenerative disorder that is characterized by a progressive decline in cognitive function. γ-secretase dysfunction is evident in many cases of early onset familial Alzheimers disease. However, the mechanism by which γ-secretase dysfunction results in memory loss and neurodegeneration is not fully understood. Here, we demonstrate that γ-secretase is localized at synapses and regulates spine formation. We identify EphA4, one of the Ephrin receptor family members, as a substrate of γ-secretase, and find that EphA4 processing is enhanced by synaptic activity. Moreover, overexpression of EphA4 intracellular domain increases the number of dendritic spines by activating the Rac signaling pathway. These findings reveal a function for EphA4-mediated intracellular signaling in the morphogenesis of dendritic spines and suggest that the processing of EphA4 by γ-secretase affects the pathogenesis of Alzheimers disease ...

Indeed 123C4 increases survival in mice models of ALS, but acts as an EphA4 agonist and not antagonist, Pellecchia said, going on to explain that an agonist is a substance that stimulates chemical action, while an antagonist blocks such action. We show that 123C4 interacting with EphA4 causes the receptor to be internalized by a process known as endocytosis - a process initiated only by an agonist. We hypothesize that by inducing receptor internalization, 123C4 effectively removes EphA4 from the surface of motor neurons.. The transgenic mouse model Pellecchia and his colleagues used for the study has been widely adopted as a standard to select drug candidates as potential ALS therapeutics. But challenges lie ahead for Pellecchias team to bring 123C4 to the clinic to confirm that the laboratory studies effectively translate to patients affected by ALS.. As in any preclinical study, we must acknowledge that several obstacles are still in the way of translating agents like 123C4 into viable ...

In this study we adopted the guide-effector bispecific antibody design that we developed previously for cell-type-specific signaling modulation (8), and achieved cell-type-specific modulation of internalization. We show that when the guide-to-effector ratio crosses over a threshold (in our EphA2/ALCAM example, 1:5), a noninternalizing antigen (ALCAM) can be rendered internalizing by the bispecific. When the guide-to-effector ratio falls below the threshold, an internalizing antigen (EphA2) can be rendered non- or slowly internalizing by the bispecific. Thus in the context of bispecific targeting, the internalization behavior of a cell surface antigen is significantly impacted by its neighboring antigens, and can be readily manipulated in either direction through bispecific-based targeting of appropriately selected guide/effector pairs.. Our study has relevance to therapeutic development. In the direction of converting a noninternalizing into an internalizing antigen, our study has direct ...
