    Abstract The field of regenerative medicine (RM), encompassing stem cell (SC) technologies, therapeutics, tissue engineering (TE), biomaterials, scaffolds and other enabling technologies provides a wide gamut of tools and tracks to combat, manage and hopefully cure serious human and animal injuries, dysfunctions and diseases. This review illustrates the trends that are becoming the major platforms in this field. The last 10 years in itself has seen major definitive observations, including multi-track directives of adult stem cell translational technologies, tissue and organ engineering protocols, iPS cell applications and understanding of the role of cancer stem cells to develop effective anti-cancer regimens. With the rapid advances of RM translational research, further advances are expected to be implemented for personalized repair and curative outcomes. RM future is bright although laden with challenges of global fragmentation which needs coherent consolidation, stringent cost and time effective regulation and long-term funding mechanisms, so clinical and diagnostic solutions are realized and recognized to combat unmet medical needs.

    Abstract Onchocerciasis (river blindness) is a neglected tropical disease that has been successfully targeted by mass drug treatment programs in the Americas and small parts of Africa. Achieving the long-term goal of elimination of onchocerciasis, however, requires additional tools, including drugs, vaccines, and biomarkers of infection. Here, we describe the transcriptome and proteome profiles of the major vector and the human host stages (L1, L2, L3, molting L3, L4, adult male, and adult female) of Onchocerca volvulus along with the proteome of each parasitic stage and of its Wolbachia endosymbiont (wOv). In so doing, we have identified stage-specific pathways important to the parasite's adaptation to its human host during its early development. Further, we generated a protein array that, when screened with well-characterized human samples, identified novel diagnostic biomarkers of O. volvulus infection and new potential vaccine candidates. This immunomic approach not only demonstrates the power of this postgenomic discovery platform but also provides additional tools for onchocerciasis control programs.
    Importance: The global onchocerciasis (river blindness) elimination program will have to rely on the development of new tools (drugs, vaccines, biomarkers) to achieve its goals by 2025. As an adjunct to the completed genomic sequencing of O. volvulus, we used a comprehensive proteomic and transcriptomic profiling strategy to gain a comprehensive understanding of both the vector-derived and human host-derived parasite stages. In so doing, we have identified proteins and pathways that enable novel drug targeting studies and the discovery of novel vaccine candidates, as well as useful biomarkers of active infection.

    Abstract Cytokines are protein/glycoprotein messengers of the immune system and have distinct autocrine and paracrine functions to modulate immunity. Recombinant cytokine proteins have been employed as biological drugs for cancer, viral and autoimmune targets. Unfortunately, systemic delivery of pharmacological doses of proteins often results in severe side effects and toxicities. As these therapeutic proteins tend to have very short half-lives and are complex to manufacture and deliver, many investigators are evaluating the genetic delivery of cytokine genes. Here, some of the promising cytokines currently under investigation for cancer therapies are examined, including interleukin (IL)-2, IL-4, IL-12, IL-24, interferon (IFN)-alpha, IFN beta, IFN gamma, granulocyte-monocyte colony-stimulating factor and tumor necrosis factor (TNF)-alpha. Chemokines are smaller chemotactic cytokines which induce migration of leukocytes, activate inflammatory responses, and are implicated in the regulation of tumor development and growth. Chemokines can modulate tumor growth via regulation of tumor-associated angiogenesis, by activation of host immunological responses or by direct inhibition of tumor cell proliferation. In this review, chemokines that have been proposed as antitumor drugs will be discussed, including Glu-Leu-Arg (ELR)-negative chemokines such as IP-10, MCP-3, MIG and SDF-1 alpha from the human CXC and C-C chemokine families.

    Abstract Efficient inhibition of human immunodeficiency virus-1 (HIV-1) replication with intracellularly expressed antiviral genes would be an important step toward clinical gene therapy for HIV-1 disease. Enzo Biochem is investigating and developing antisense genes as a potential gene therapy approach against a variety of conditions including acquired immunodeficiency syndrome (AIDS), cancer and hepatitis. The subsidiary of Enzo Biochem, Enzo Therapeutics, utilized its StealthVector technology and initiated phase I trials in July 1998 [291511,307156]. StealthVector, which is comprised of independent antisense sequences directed against two functional HIV-1 regions, is involved in regulation of gene expression soon after HIV infection, transactivation response (TAR) and tat/rev. StealthVector localizes primarily in the cell nucleus, where it could be most effective in inhibiting viral growth.

    Abstract Abnormalities in smooth muscle cell (SMC) proliferation and differentiation underlie the pathogenesis of proliferative vascular diseases. MDA-7 (HUGO approved symbol IL24) is a unique gene, originally identified as a tumor suppressor and more recently shown to have cytokine activity. MDA-7/IL24 has been implicated in apoptosis and cellular differentiation in tumor cells and in tumor invasion/metastasis in clinical specimens-properties central to SMC remodeling during proliferative vascular diseases. In this study, we evaluated the effects of overexpressing MDA-7/IL24 in various SMC: the apparently "normal" rat PAC1 cell line, primary human coronary artery SMC, and normal rat aortic SMC. We transduced SMC with adenovirus-mda7 (Ad-mda7) or control virus (Ad-Luc) and assessed cell viability, apoptosis, and migration. Ad-mda7 suppressed PAC1 cell growth in a dose-dependent manner while having no effect on normal primary human coronary artery cells or rat aortic SMC, despite strong expression of the MDA-7 transgene in all SMC. Similarly, Ad-mda7 treatment induced apoptosis in PAC1 cells with essentially no effect on normal coronary and rat aortic SMC. Ad-mda7 also inhibited serum-stimulated PAC1 cell migration. Karyotype analysis of PAC1 cells revealed that they exhibit multiple chromosomal aberrations. Importantly, recombinant MDA-7 did not elicit cell death or STAT-3 activation in PAC1 SMC, suggesting that the effects of Ad-mda7 were mediated through an intracellular pathway. These data demonstrate that Ad-mda7 exhibits selectivity in apoptosis induction and growth suppression in an atypical SMC line, raising new questions pertaining to heterogeneity in SMC death susceptibility.

    Abstract HEPCloud is rapidly becoming the primary system for provisioning compute resources for all Fermilab-affiliated experiments. In order to reliably meet the peak demands of the next generation of High Energy Physics experiments, Fermilab must plan to elastically expand its computational capabilities to cover the forecasted need. Commercial cloud and allocation-based High Performance Computing (HPC) resources both have explicit and implicit costs that must be considered when deciding when to provision these resources, and at which scale. In order to support such provisioning in a manner consistent with organizational business rules and budget constraints, we have developed a modular intelligent decision support system (IDSS) to aid in the automatic provisioning of resources spanning multiple cloud providers, multiple HPC centers, and grid computing federations. In this paper, we discuss the goals and architecture of the HEPCloud Facility, the architecture of the IDSS, and our early experience in using the IDSS for automated facility expansion both at Fermi and Brookhaven National Laboratory.

    Abstract The tumor-suppressive activity of melanoma differentiation-associated gene-7 (mda-7), also known as interleukin 24 (IL-24), has been shown in a spectrum of human cancer cells in vitro and in vivo. However, mechanisms responsible for antitumor activity of mda-7 in human ovarian cancer cells have not been identified. We investigated the therapeutic activity and underlying mechanisms of adenovirus-mediated mda-7 gene (Ad-mda7) transfer in human ovarian cancer cells. Ad-mda7 treatment resulted in overexpression of MDA-7/IL-24 protein in both ovarian cancer and normal ovarian epithelial cells. However, Ad-mda7 significantly (P = 0.001) inhibited cell proliferation and induced apoptosis only in tumor cells and not in normal cells. Studies addressing the mechanism of action of Ad-mda7-induced tumor cell apoptosis revealed early activation of the transcription factors c-Jun and activating transcription factor 2, which in turn stimulated the transcription of an immediate downstream target, the death-inducer Fas ligand (FasL), and its cognate receptor Fas. Associated with the activation of Fas-FasL was the activation of nuclear factor kappaB and induction of Fas-associated factor 1, Fas-associated death domain, and caspase-8. Promoter-based reporter gene analyses showed that Ad-mda7 specifically activated the Fas promoter. Inhibition of Fas using small interfering RNA resulted in a significant decrease in Ad-mda7-mediated tumor cell death. Additionally, blocking of FasL with NOK-1 antibody abrogated Ad-mda7-mediated apoptosis. Collectively, these results show that Ad-mda7-mediated killing of human ovarian cancer cells involves activation of the Fas-FasL signaling pathway, a heretofore unrecognized mediator of MDA-7 apoptosis induction.

    Abstract The melanoma differentiation-associated gene-7 (mda-7) is a member of the interleukin-10 cytokine family and a novel tumor suppressor gene. Adenoviral-mediated mda-7 (Ad-mda7) gene transfer has tumor-specific growth inhibitory and proapoptotic effects in a broad spectrum of cancer cells. In breast cancer cells, adenoviral-induced mda-7 expression triggers antiproliferative effects by downregulation of survival signals, such as Bcl-2 and Akt. The anti-human epidermal growth factor receptor-2 (Her-2) monoclonal antibody, Trastuzumab (Herceptin), increases the sensitivity of Her-2/neu-overexpressing breast cancer cells to chemotherapeutic agents and radiotherapy. In this study, we evaluate the effects of treatment with Ad-mda7 and Herceptin combination therapy in a panel of Her-2/neu-overexpressing cell lines, and in established tumors in nude mice. Compared to individual treatments, the combination of Ad-mda7 and Herceptin elicits supra-additive antitumor activity in Her-2/neu-overexpressing tumor cell lines: increased cell death, cell cycle block and apoptosis. The Ad-mda7 and Herceptin interaction was shown to be synergistic by isobologram analysis. Ad-mda7 does not alter cell surface Her-2/neu levels, but the combination of Ad-mda7+Herceptin results in increased expression of cell surface E-cadherin with concomitant translocation of beta-catenin from the nucleus to the cell membrane. In vivo, the combination of Ad-mda7 and Herceptin showed significantly increased antitumor activity (P<0.003) against Her-2/neu-overexpressing tumors. These data suggest that the combination of Ad-mda7 with Herceptin may be a novel therapy for breast cancer patients whose tumors overexpress Her-2/neu. The observed synergistic effect may improve treatment options for otherwise poorly responsive, Her-2-positive, breast cancer patients.

    Abstract We have previously observed the suppression of lung tumor growth in response to overexpression of melanoma differentiation-associated gene-7 (MDA-7)/interleukin-24 (IL-24; approved gene symbol IL24) in vitro and in vivo. MDA-7/IL-24 exerts its tumor-suppressive effects by multiple mechanisms, including the activation of the caspase cascade and the inhibition of angiogenesis. In this study, we used an adenoviral vector (Ad-mda7) to examine the effect of the ectopic production of MDA-7/IL-24 on cell migration and invasion by human non-small-cell lung carcinoma cells. Lung tumor cells (H1299 and A549) treated in vitro with Ad-mda7 migrated and invaded less than cells treated with phosphate-buffered saline (PBS) or Ad-Luc (vector control). MDA-7/IL-24 inhibited migration and invasion by down-regulating the production of phosphatidylinositol 3-kinase/protein kinase B, focal adhesion kinase, and matrix metalloproteinase-2 and -9 relative to PBS and Ad-Luc. Furthermore, tumor cells treated with Ad-mda7 ex vivo or with DOTAP:Chol-mda7 complex in vivo formed significantly fewer tumors in an experimental lung metastasis model. These results show that MDA-7/IL-24 inhibits invasion and migration by lung cancer cells by down-regulating proteins associated with these processes, resulting in reduced metastasis. Thus, Ad-mda7 should be considered a therapeutic agent that can inhibit primary tumor growth and prevent metastasis.
