Abstract
Patients diagnosed with Anaplastic Large Cell Lymphoma (ALCL) are still treated with toxic multi-agent chemotherapy and as many as 25-50% of patients relapse. To understand disease pathology and to uncover novel targets for therapy, Whole-Exome Sequencing (WES) of Anaplastic Lymphoma Kinase (ALK)+ ALCL was performed as well as Gene-Set Enrichment Analysis. This revealed that the T-cell receptor (TCR) and Notch pathways were the most enriched in mutations. In particular, variant T349P of NOTCH1, which confers a growth advantage to cells in which it is expressed, was detected in 12% of ALK+ and ALK- ALCL patient samples. Furthermore, we demonstrate that NPM-ALK promotes NOTCH1 expression through binding of STAT3 upstream of NOTCH1. Moreover, inhibition of NOTCH1 with γ-secretase inhibitors (GSIs) or silencing by shRNA leads to apoptosis; co-treatment in vitro with the ALK inhibitor Crizotinib led to additive/synergistic anti-tumour activity suggesting this may be an appropriate combination therapy for future use in the circumvention of ALK inhibitor resistance. Indeed, Crizotinib-resistant and sensitive ALCL were equally sensitive to GSIs. In conclusion, we show a variant in the extracellular domain of NOTCH1 that provides a growth advantage to cells and confirm the suitability of the Notch pathway as a second-line druggable target in ALK+ ALCL.

Abstract
Simple Summary Anaplastic lymphoma kinase positive anaplastic large cell lymphomas are a pediatric disease, which still needs treatment improvement. Crizotinib was the first ALK-targeted inhibitor used in clinics, but relapses are now known to occur. Current research efforts indicate that combined therapies could represent a superior strategy to eradicate malignant cells and prevent tumor recurrence. Autophagy is a self-digestion cellular process, known to be induced upon diverse cancer therapies. Our present work demonstrates that the potentiation of the crizotinib-induced autophagy flux, through the serine/threonine kinase RAF1 downregulation, drives ALK+ ALCL cells to death. These results should encourage further investigations on the therapeutic modulation of autophagy in this particular cancer settings and other ALK-related malignancies. Abstract Anaplastic lymphoma kinase positive anaplastic large cell lymphomas (ALK+ ALCL) are an aggressive pediatric disease. The therapeutic options comprise chemotherapy, which is efficient in approximately 70% of patients, and targeted therapies, such as crizotinib (an ALK tyrosine kinase inhibitor (TKI)), used in refractory/relapsed cases. Research efforts have also converged toward the development of combined therapies to improve treatment. In this context, we studied whether autophagy could be modulated to improve crizotinib therapy. Autophagy is a vesicular recycling pathway, known to be associated with either cell survival or cell death depending on the cancer and therapy. We previously demonstrated that crizotinib induced cytoprotective autophagy in ALK+ lymphoma cells and that its further intensification was associated with cell death. In line with these results, we show here that combined ALK and Rapidly Accelerated Fibrosarcoma 1 (RAF1) inhibition, using pharmacological (vemurafenib) or molecular (small interfering RNA targeting RAF1 (siRAF1) or microRNA-7-5p (miR-7-5p) mimics) strategies, also triggered autophagy and potentiated the toxicity of TKI. Mechanistically, we found that this combined therapy resulted in the decrease of the inhibitory phosphorylation on Unc-51-like kinase-1 (ULK1) (a key protein in autophagy initiation), which may account for the enforced autophagy and cytokilling effect. Altogether, our results support the development of ALK and RAF1 combined inhibition as a new therapeutic approach in ALK+ ALCL.

Abstract
Systemic anaplastic large cell lymphoma (ALCL) is an aggressive T-cell lymphoma most commonly seen in children and young adults. The majority of pediatric ALCLs are associated with the t(2;5)(p23;q35) translocation which fuses the Anaplastic Lymphoma Kinase (ALK) gene with the Nucleophosmin (NPM) gene. The NPM-ALK fusion protein is a constitutively-active tyrosine kinase, and plays a major role in tumor pathogenesis. In an effort to advance novel diagnostic approaches and the understanding of the function of this fusion protein in cancer cells, we expressed in E. coli, purified and characterized human NPM-ALK fusion protein to be used as a standard for estimating expression levels in cultured human ALCL cells, a key tool in ALCL pathobiology research. We estimated that NPM-ALK fusion protein is expressed at substantial levels in both Karpas 299 and SU-DHL-1 cells (ca. 4-6 million molecules or 0.5-0.7 pg protein per cell; based on our in-house developed NPM-ALK ELISA; LOD of 40 pM) as compared to the ubiquitous β-actin protein (ca. 64 million molecules or 4.5 pg per lymphocyte). We also compared NPM-ALK/ β-actin ratios determined by ELISA to those independently determined by two-dimensional electrophoresis and showed that the two methods are in good agreement.

Abstract
Nucleophosmin-anaplastic lymphoma kinase (NPM-ALK) fusion genes resulting from the translocation t(2;5)(p23;q35) are present in almost 90% of childhood ALK-positive anaplastic large-cell lymphomas (ALCL). Detection and quantification of minimal disseminated disease (MDD) by measuring NPM-ALK fusion transcript levels in the blood provide independent prognostic parameters. Characterization of the genomic breakpoints provides insights into the pathogenesis of the translocation and allows for DNA-based minimal disease monitoring. We designed a nested multiplex PCR assay for identification and characterization of genomic NPM-ALK fusion sequences in 45 pediatric ALCL-patients, and used the sequences for quantitative MDD monitoring. Breakpoint analysis indicates the involvement of inaccurate non-homologous end joining repair mechanisms in the formation of NPM-ALK fusions. Parallel quantification of RNA and DNA levels in the cellular fraction of 45 blood samples from eight patients with NPM-ALK-positive ALCL correlated, as did cell-free circulating NPM-ALK DNA copies in the plasma fraction of 37 blood samples. With genomic NPM-ALK fusion sequence quantification, plasma samples of ALCL patients become an additional source for MRD-assessment. Parallel quantification of NPM-ALK transcripts and fusion genes in ALCL cell lines treated with the ALK kinase inhibitor crizotinib illustrates the potential value of supplementary DNA-based quantification in particular clinical settings.

Abstract
ALK-positive Anaplastic Large Cell Lymphoma (ALCL) represents a subset of Non-Hodgkin Lymphoma whose treatment benefited from crizotinib development, a dual ALK/MET inhibitor. Crizotinib blocks ALK-triggered pathways such as PI3K/AKT/mTOR, indispensable for survival of ALK-driven tumors. Despite the positive impact of targeted treatment in ALCL, resistant clones are often selected during therapy. Strategies to overcome resistance include the design of second generation drugs and the use of combined therapies that simultaneously target multiple nodes essential for cells survival. We investigated the effects of combined ALK/mTOR inhibition. We observed a specific synergistic effect of combining ALK inhibitors with an mTOR inhibitor (temsirolimus), in ALK+ lymphoma cells. The positive cooperation resulted in an increased inhibition of mTOR effectors, compared to single treatments, a block in G0/G1 phase and induction of apoptosis. The combination was able to prevent the selection of resistant clones, while long-term exposure to single agents led to the establishment of resistant cell lines, with either ALK inhibitor or temsirolimus. In vivo, mice injected with Karpas 299 cells and treated with low dose combination showed complete regression of tumors, while only partial inhibition was obtained in single agents-treated mice. Upon treatment stop the combination was able to significantly delay tumor relapses. Re-challenge of relapsed tumors at a higher dose led to full regression of xenografts in the combination group, but not in mice treated with lorlatinib alone. In conclusion, our data suggest that the combination of ALK and mTOR inhibitors could be a valuable therapeutic option for ALK+ ALCL patients.

Abstract
Nucleophosmin‐anaplastic lymphoma kinase‐expressing (NPM‐ALK+) T‐cell lymphoma is an aggressive neoplasm that is more commonly seen in children and young adults. The pathogenesis of NPM‐ALK+ T‐cell lymphoma is not completely understood. Wild‐type ALK is a receptor tyrosine kinase that is physiologically expressed in neural tissues during early stages of human development, which suggests that ALK may interact with neurotrophic factors. The aberrant expression of NPM‐ALK results from a translocation between the ALK gene on chromosome 2p23 and the NPM gene on chromosome 5q35. The nerve growth factor (NGF) is the first neurotrophic factor attributed to non‐neural functions including cancer cell survival, proliferation, and metastasis. These functions are primarily mediated through the tropomyosin receptor kinase A (TrkA). The expression and role of NGF/TrkA in NPM‐ALK+ T‐cell lymphoma are not known. In this study, we tested the hypothesis that TrkA signaling is upregulated and sustains the survival of this lymphoma. Our data illustrate that TrkA and NGF are expressed in five NPM‐ALK+ T‐cell lymphoma cell lines and TrkA is expressed in 11 of 13 primary lymphoma tumors from patients. In addition, we found evidence to support that NPM‐ALK and TrkA functionally interact. A selective TrkA inhibitor induced apoptosis and decreased cell viability, proliferation, and colony formation of NPM‐ALK+ T‐cell lymphoma cell lines. These effects were associated with downregulation of cell survival regulatory proteins. Similar results were also observed using specific knockdown of TrkA in NPM‐ALK+ T‐cell lymphoma cells by siRNA. Importantly, the inhibition of TrkA signaling was associated with antitumor effects in vivo, because tumor xenografts in mice regressed and the mice exhibited improved survival. In conclusion, TrkA plays an important role in the pathogenesis of NPM‐ALK+ T‐cell lymphoma, and therefore, targeting TrkA signaling may represent a novel approach to eradicate this aggressive neoplasm.

Abstract
NPM-ALK⁺ T-cell anaplastic large-cell lymphoma (ALCL) is an aggressive type of cancer. Standard treatment of NPM-ALK⁺ ALCL is CHOP polychemotherapy. Although patients initially respond favorably to CHOP, resistance, relapse, and death frequently occur. Recently, selective targeting of ALK has emerged as an alternative therapeutic strategy. ASP3026 is a second-generation ALK inhibitor that can overcome crizotinib resistance in non-small cell lung cancer, and is currently being evaluated in clinical trials of patients with ALK⁺ solid tumors. However, NPM-ALK⁺ ALCL patients are not included in these trials. We studied the effects of ASP3026 on NPM-ALK⁺ ALCL cell lines in vitro and on systemic lymphoma growth in vivo. ASP3026 decreased the viability, proliferation, and colony formation, as well as induced apoptotic cell death of NPM-ALK⁺ ALCL cells. In addition, ASP3026 significantly reduced the proliferation of 293T cells transfected with NPM-ALK mutants that are resistant to crizotinib and downregulated tyrosine phosphorylation of these mutants. Moreover, ASP3026 abrogated systemic NPM-ALK⁺ ALCL growth in mice. Importantly, the survival of ASP3026-treated mice was superior to that of control and CHOP-treated mice. Our data suggest that ASP3026 is an effective treatment for NPM-ALK⁺ ALCL, and support the enrollment of patients with this lymphoma in the ongoing clinical trials.

Abstract
Background Dual phosphatidylinositol-3-kinase (PI3K)/mammalian target of rapamycin (mTOR) inhibition offers an attractive therapeutic strategy in anaplastic large cell lymphoma depending on oncogenic nucleophosmin-anaplastic lymphoma kinase (NPM-ALK) signaling. We tested the efficacy of a novel dual PI3K/mTOR inhibitor, NVP-BGT226 (BGT226), in two anaplastic large cell lymphoma cell lines in vitro and in vivo and performed an early response evaluation with positron emission tomography (PET) imaging using the standard tracer, 2-deoxy-2-[18F]fluoro-D-glucose (FDG) and the thymidine analog, 3′-deoxy-3′-[18F] fluorothymidine (FLT). Methods The biological effects of BGT226 were determined in vitro in the NPM-ALK positive cell lines SU-DHL-1 and Karpas299 by 3-[4,5-Dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay, propidium iodide staining, and biochemical analysis of PI3K and mTOR downstream signaling. FDG-PET and FLT-PET were performed in immunodeficient mice bearing either SU-DHL-1 or Karpas299 xenografts at baseline and 7 days after initiation of treatment with BGT226. Lymphomas were removed for immunohistochemical analysis of proliferation and apoptosis to correlate PET findings with in vivo treatment effects. Results SU-DHL-1 cells showed sensitivity to BGT226 in vitro, with cell cycle arrest in G0/G1 phase and an IC50 in the low nanomolar range, in contrast with Karpas299 cells, which were mainly resistant to BGT226. In vivo, both FDG-PET and FLT-PET discriminated sensitive from resistant lymphoma, as indicated by a significant reduction of tumor-to-background ratios on day 7 in treated SU-DHL-1 lymphoma-bearing animals compared with the control group, but not in animals with Karpas299 xenografts. Imaging results correlated with a marked decrease in the proliferation marker Ki67, and a slight increase in the apoptotic marker, cleaved caspase 3, as revealed by immunostaining of explanted lymphoma tissue. Conclusion Dual PI3K/mTOR inhibition using BGT226 is effective in ALK-positive anaplastic large cell lymphoma and can be monitored with both FDG-PET and FLT-PET early on in the course of therapy.

Abstract
BACKGROUND ALK+ anaplastic large cell lymphoma (ALCL) is usually a disease of young patients. We investigated phosphatidylinositol-3 kinase (PI3K)/Akt pathway-associated factors in pediatric cases and cell lines. PROCEDURE Patient materials consisted of tissue slides of ALK+/CD30+ ALCL from 33 patients treated on Pediatric Oncology Group protocols (9219, n = 8 and 9315, n = 25). Slides were examined by immunohistochemistry for phospho(p)-Akt and PTEN, the primary feedback regulator of the pathway, as well as for p27kip1 and stathmin-1. ALCL cell lines SUDHL-1 and Karpas-299 were examined for ALK, pALK, pAkt, p27/Kip1, PTEN, pPTEN, CD30, pSTAT3, and pSTAT5; ALK inhibition was performed using compound PF-2341066 and PTEN genes were sequenced. RESULTS A majority of patients expressed pAkt, PTEN, and stathmin, with p27kip1 levels less than controls. Cell lines showed expression of ALK, pALK, pSTAT3, pSTAT5, CD30, pAkt, PTEN, and pPTEN, with p27 slightly less than positive controls, and germline PTEN DNA. There was evidence of phosphorylated PTEN (pPTEN) associated with inhibited function. Pharmacologic inhibition of activated ALK diminished pSTAT3, pSTAT5, and CD30 expression but not pAkt or pPTEN in cultured cell lines. CONCLUSION We conclude that the PI3K/Akt pathway is activated in many, though not all, pediatric ALK+ ALCL. Our data suggest that activation of this pathway involves post-translational regulation of PTEN. Pharmacologic inhibition of activated ALK does not reduce modest levels of activated Akt as it does with the more abundant levels of activated STAT3 or STAT5. Future therapy of ALCL might, in selected patients, best combine agents inhibiting PI3K/Akt with those targeting ALK.

Abstract
Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase (RTK) involved in the genesis of several human cancers; indeed, ALK was initially identified in constitutively activated and oncogenic fusion forms--the most common being nucleophosmin (NPM)-ALK--in a non-Hodgkin's lymphoma (NHL) known as anaplastic large-cell lymphoma (ALCL) and subsequent studies identified ALK fusions in the human sarcomas called inflammatory myofibroblastic tumors (IMTs). In addition, two recent reports have suggested that the ALK fusion, TPM4-ALK, may be involved in the genesis of a subset of esophageal squamous cell carcinomas. While the cause-effect relationship between ALK fusions and malignancies such as ALCL and IMT is very well established, more circumstantial links implicate the involvement of the full-length, normal ALK receptor in the genesis of additional malignancies including glioblastoma, neuroblastoma, breast cancer, and others; in these instances, ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops involving the reported ALK ligands, pleiotrophin (PTN) and midkine (MK). There are no currently available ALK small-molecule inhibitors approved for clinical cancer therapy; however, recognition of the variety of malignancies in which ALK may play a causative role has recently begun to prompt developmental efforts in this area. This review provides a succinct summary of normal ALK biology, the confirmed and putative roles of ALK fusions and the full-length ALK receptor in the development of human cancers, and efforts to target ALK using small-molecule kinase inhibitors.

Abstract
OBJECTIVE Heat shock protein 90 (HSP90) chaperones and maintains the molecular integrity of a variety of signal transduction proteins, including the nucleophosmin-anaplastic lymphoma kinase (NPM-ALK) oncogenic protein, a genetic abnormality that is frequently observed in anaplastic large cell lymphoma (ALCL) cells. Here we demonstrate that HSP90 is overexpressed in primary and cultured ALK-positive and ALK-negative ALCL cells, and we evaluate the potential role of the small molecule inhibitor of HSP90, 17-allylamino-17-demethoxygeldanamycin (17-AAG) in treating ALCL. METHODS The antiproliferative effect of 17-AAG-cultured cells was determined by MTS assay. Apoptosis and cell-cycle arrest were determined by Annexin-V/propidium iodide and propidium iodide staining, respectively, and fluorescein-activated cell sorting analysis. Expression of HSP90 was evaluated by immunohistochemistry, and molecular changes were determined by Western blot. RESULTS Treatment of cultured ALCL cells with 17-AAG induced cell-cycle arrest and apoptosis, irrespective of ALK expression. At the molecular level, 17-AAG induced degradation of ALK and Akt proteins, dephosphorylated extracellular signal-regulated kinase, and degraded the cell-cycle regulatory protein cyclin D1 and its cyclin-dependent kinases, CDK4 and CDK6, but had a differential effect on p27 and p53 proteins. Inhibition of extracellular signal-regulated kinase phosphorylation by the mitogen activated protein kinase inhibitor U0126 induced cell death in all ALCL cell lines, and sublethal concentration 17-AAG showed synergistic antiproliferative effects when combined with U0126 or doxorubicin. CONCLUSION Our data demonstrate that targeting HSP90 function by 17-AAG may offer a novel therapeutic strategy for ALCL, either as single-agent activity or by combining 17-AAG with conventional or targeted therapeutic schemes.

Abstract
Recurrent chromosomal aberrations in hematopoietic tumors target genes involved in pathogenesis. Their identification and functional characterization are therefore important for the establishment of rational therapies. Here, we investigated genomic amplification at 7q22 in the T-cell lymphoma cell line SU-DHL-1 belonging to the subtype of anaplastic large-cell lymphoma (ALCL). Cytogenetic analysis mapped this amplicon to 86-95 Mb. Copy-number determination quantified the amplification level at 5- to 6-fold. Expression analysis of genes located within this region identified cyclin-dependent kinase 6 (CDK6) as a potential amplification target. In comparison with control cell lines, SU-DHL-1 expressed considerably higher levels of CDK6. Functionally, SU-DHL-1 cells exhibited reduced sensitivity to rapamycin treatment, as indicated by cell growth and cell cycle analysis. Rapamycin reportedly inhibits degradation of the CDK inhibitor p27 with concomitant downregulation of cyclin D3, implying a proliferative advantage for CDK6 overexpression. Amplification of the CDK6 locus was analyzed in primary T-cell lymphoma samples and, while detected infrequently in those classified as ALCL (1%), was detected in 23% of peripheral T-cell lymphomas not otherwise specified. Taken together, analysis of the 7q22 amplicon identified CDK6 as an important cell cycle regulator in T-cell lymphomas, representing a novel potential target for rational therapy.

Abstract
More than half of anaplastic large-cell lymphoma (ALCL) are associated with chromosomal translocation t(2;5)(p23;q35) that leads to the expression of nucleophosmin-anaplastic lymphoma kinase (NPM-ALK) oncoprotein. NPM-ALK activates the antiapoptotic phosphatidylinositol-3 kinase/Akt (PI3K/Akt) signaling pathway, which plays a critical role in cell survival and apoptosis. Inhibition of the PI3K/Akt pathway has been considered as a therapeutic target for cancer where PI3K/Akt activation is a causative factor. Genistein, a natural isoflavonoid found in soy products, has been shown to inhibit cell growth and induce apoptosis in a wide variety of cell lines. Here, we demonstrated that treatment of two t(2;5) ALCL cell lines, SUDHL-1 and Karpas299, with genistein induced apoptosis in a time- and dose-dependent manner. Concurrently, these cells exhibited a decrease in Akt protein levels and subsequent downregulation of Akt activity (Akt phosphorylation). Furthermore, genistein treatment induced mitochondrial membrane potential change, caspase-3 activation and PARP cleavage. From these results, we conclude that inhibition of the Akt signaling pathway and induction of apoptosis by genistein could be used as a new treatment modality for the prevention and/or treatment of t(2;5) ALCL and other hematopoietic malignancies.

Abstract
The normal functions of full-length anaplastic lymphoma kinase (ALK) remain to be completely elucidated. Although considered to be important in neural development, recent studies in Drosophila also highlight a role for ALK in gut muscle differentiation. Indeed, the Drosophila model offers a future arena for the study of ALK, its ligands and signalling cascades. The discovery of activated fusion forms of the ALK tyrosine kinase in anaplastic large cell lymphoma (ALCL) has dramatically improved our understanding of the pathogenesis of these lymphomas and enhanced the pathological diagnosis of this subtype of non-Hodgkin's lymphoma (NHL). Likewise, the realisation that a high percentage of inflammatory myofibroblastic tumours express activated-ALK fusion proteins has clarified the causation of these mesenchymal neoplasms and provided for their easier discrimination from other mesenchymal-derived inflammatory myofibroblastic tumour (IMT) mimics. Recent reports of ALK expression in a range of carcinoma-derived cell lines together with its apparent role as a receptor for PTN and MK, both of which have been implicated in tumourigenesis, raise the possibility that ALK-mediated signalling could play a role in the development and/or progression of a number of common solid tumours. The therapeutic targeting of ALK may prove to have efficacy in the treatment of many of these neoplasms.

Abstract
Abstract
Between 30% and 50% of patients with advanced-stage anaplastic large-cell lymphoma (ALCL) harbor the balanced chromosomal rearrangement t(2;5)(p23;q35), which results in the generation of the fusion protein nucleophosmin-anaplastic lymphoma kinase (NPM-ALK). To further study survival signaling by NPMALK, we generated Ba/F3 cell lines with either inducible or constitutive expression of NPM-ALK and examined the regulation of the AKT target FOXO3a. We hypothesized that NPM-ALK signaling through phosphoinositol 3-kinase (PI 3-kinase) and AKT would regulate FOXO3a, a member of the forkhead family of transcription factors, thereby stimulating proliferation and blocking programmed cell death in NPM-ALK-transformed cells. In Ba/F3 cells with induced or constitutive expression of NPM-ALK, concomitant AKT activation and phosphorylation of its substrate, FOXO3a, was observed. In addition, transient expression of NPM-ALK in U-20S cells inhibited FOXO3a-mediated transactivation of reporter gene expression. Furthermore, NPM-ALK-induced FOXO3a phosphorylation in Ba/F3 cells resulted in nuclear exclusion of this transcriptional regulator, up-regulation of cyclin D2 expression, and down-regulation of p27kip1 and Bim-1 expression. NPMALK reversal of proliferation arrest and of p27kip1 induction was dependent on the phosphorylation of FOXO3a. Thus, FOXO3a is a barrier to hematopoietic transformation that is overcome by phosphorylation and cytoplasmic relocalization induced by the expression of NPM-ALK. (Blood. 2004;103:4622-4629)

Abstract
Signal transducer and activator of transcription 3 (STAT3), normally activated by Janus kinase (JAK) in response to cytokine stimulation, has been shown to have oncogenic potential. In addition to JAK, recent data suggest that STAT3 can also be activated by other proteins such as the aberrant fusion protein, NPM-ALK, which is expressed in a subset of systemic anaplastic large cell lymphoma (ALCL). In this study, we investigated the possible role of JAK in activating STAT3 in ALCL using two ALK-positive ALCL cell lines, Karpas 299 and SU-DHL-1. At the steady state, JAK3 showed detectable tyrosine phosphorylation by immunoprecipitation. Treatment with AG490, a JAK inhibitor, decreased but did not completely abrogate tyrosine phosphorylation of JAK3 and STAT3 in a concentration-dependent manner. Similar results were obtained using two other inhibitors of JAK3, WHI-P131 and WHI-P154. These biochemical changes were associated with apoptosis in both cell lines that was coupled with activation of caspase 3 and decreased bcl-xL and bcl-2. Cell cycle analysis revealed a decrease in the S phase, which may be attributed to cyclin D3 downregulation and p21(waf1) upregulation. Importantly, the tyrosine kinase activity of NPM-ALK, as assessed by an in vitro assay, decreased with increasing concentrations of AG490. Our findings highlight the importance of JAK3 in activating STAT3 in ALCL, and that NPM-ALK-mediated activation of STAT3 is influenced by the functional status of JAK3.

Abstract
SUDHL-1 cells, derived from human t(2;5)-anaplastic large cell lymphoma (ALCL) were kept in culture for 25 days and analyzed for p27(Kip1)-expression, cell cycle, apoptosis, morphology and phenotype as compared with matched controls at different time points after infection with recombinant adenovirus expressing p27(Kip1) (Adp27). The presence of any change in the cell phenotype occurring during the persistent exogenous expression of p27(Kip1) would be indicative of a "clone" of cells surviving apoptosis by reversing G1 arrest. The level of alpha(nu)beta(5) integrin was completely down regulated in cells infected with Adp27 as assessed by flow cytometry and by immunoprecipitation analysis after 14 days of infection. SUDHL-1 cells regained a significant level of alpha(nu)beta(5) integrin on the cell surface after 25 days of infection with Adp27. Based on the importance of integrins in tumor cell proliferation, we speculate that the down regulation of alpha(nu)beta(5) integrin on the surface of SUDHL-1 cells may represent a less tumorigenic phenotype occurring as a consequence of prolonged expression of p27(Kip1).

Abstract
The literature has seen an incredible booming of publications related to the use of recombinant adenoviruses as therapeutic tools for lymphoproliferative disorders over the last decade. Several approaches of adenovirus-mediated gene expression have been used to transfect cell lines that are derived from lymphoid tumors and would have otherwise been refractory to other transfection methods. The identification of high-affinity receptor for human adenoviruses serotype 2 and 5, the coxsackie-adenovirus receptor (CAR), has raised the question about its relevance for the efficacy of recombinant adenovirus-mediated gene therapy. We review published studies that have analyzed the use of recombinant adenovirus vectors expressing cytotoxic genes for gene therapy in lymphomas, chronic lymphocytic leukemia and multiple myeloma. For simplicity, we group all these diseases under the term lymphoproliferative disorders. We analyze the use of recombinant adenovirus-mediated cytotoxicity by assessing the importance of the biochemical and intrinsic signaling pathways interacting with the products of the exogenous viral-mediated expression. Ultimately, we discuss studies that have been finalized to by-pass the limitations of the biodistribution of CAR by modifying or targeting adenovirus to other membrane proteins in cells derived from lymphoproliferative disorders.

Abstract
We investigated the response of SUDHL-1 and L428 cells, derived from t(2;5)-anaplastic large cell lymphoma (ALCL) and Hodgkin's disease (HD), respectively, to recombinant adenoviruses expressing cyclin-dependent kinase inhibitors (CDKIs) p27Kip1 (Adp27), p21Waf1 (Adp21) and p16INK4A (Adp16). Cell cycle analysis of SUDHL-1 cells after 24 h of infection with 200 multiplicity of infection (MOI) of Adp27, Adp21, and Adp16, showed very high levels of cell debris in the subG1 area. The magnitude of cell debris-events was Adp27/Adp21 > Adp16. Cell cycle analysis of L428 cells revealed absence of cell debris and increased G2 phase in all the groups of cells tested as compared to the controls (mock and AdNull). A minimal increase in G1 phase was also evident in cells infected with Adp27 (52%) compared to uninfected cells (43%), AdNull (45%) and to cells infected with Adp21 (37%) and Adp16 (31%). The presence of significant levels of Coxsackie-adenovirus receptor (CAR) on the cell surface of L428 cells excluded the cell membrane-barrier as responsible for the differences in cell observed in response to the recombinant adenovirus-mediated CDKIs expression as compared to SUDHL-1. We also showed that the recombinant adenovirus-mediated cytotoxicity measured as apoptosis was MOI- and vector-dependent in SUDHL-1 cells at lower MOI (100). In conclusion, the therapeutic effect induced by recombinant adenoviruses expressing p27Kip1, p21Waf1 and p16INK4A is cell-dependent in cells derived from selected lymphoid malignancies. Biochemical cellular differences more than cell surface barriers seem to be responsible for differences in response to recombinant adenovirus-mediated expression of cytotoxic genes. Moreover, the cytotoxicity of recombinant adenoviruses expressing p27Kip1, p21Waf1 and p16INK4A may be further explored as a tool for gene therapy of t(2;5)-derived ALCL.
