Abstract
Cancer virotherapy is an alternative therapeutic approach based on the viruses that selectively infect and kill tumor cells. Vaccinia virus (VV) is a member of the Poxviridae, a family of enveloped viruses with a large linear double-stranded DNA genome. The proven safety of the VV strains as well as considerable transgene capacity of the viral genome, make VV an excellent platform for creating recombinant oncolytic viruses for cancer therapy. Furthermore, various genetic modifications can increase tumor selectivity and therapeutic efficacy of VV by arming it with the immune-modulatory genes or proapoptotic molecules, boosting the host immune system, and increasing cross-priming recognition of the tumor cells by T-cells or NK cells. In this review, we summarized the data on bioengineering approaches to develop recombinant VV strains for enhanced cancer immunotherapy.

Abstract
Gastric cancer (GC) is a leading contributor to global cancer incidence and mortality. According to the GLOBOCAN 2020 estimates of incidence and mortality for 36 cancers in 185 countries produced by the International Agency for Research on Cancer (IARC), GC ranks fifth and fourth, respectively, and seriously threatens the survival and health of people all over the world. Therefore, how to effectively treat GC has become an urgent problem for medical personnel and scientific workers at this stage. Due to the unobvious early symptoms and the influence of some adverse factors such as tumor heterogeneity and low immunogenicity, patients with advanced gastric cancer (AGC) cannot benefit significantly from treatments such as radical surgical resection, radiotherapy, chemotherapy, and targeted therapy. As an emerging cancer immunotherapy, oncolytic virotherapies (OVTs) can not only selectively lyse cancer cells, but also induce a systemic antitumor immune response. This unique ability to turn unresponsive 'cold' tumors into responsive 'hot' tumors gives them great potential in GC therapy. This review integrates most experimental studies and clinical trials of various oncolytic viruses (OVs) in the diagnosis and treatment of GC. It also exhaustively introduces the concrete mechanism of invading GC cells and the viral genome composition of adenovirus and herpes simplex virus type 1 (HSV-1). At the end of the article, some prospects are put forward to determine the developmental directions of OVTs for GC in the future.

Abstract
Objective: In this study, expression of Interleukin-2, Interleukin-4, Interleukin-10 and transforming growth factor beta in diffuse and intestinal type gastric cancers from Mexican patients was assessed for use as markers of malignancy. Methods: A total of 30 biopsies from gastric adenocarcinomas, 60% diffuse, 20% intestinal and 20% mixed in type, were studied by immunohistochemistry. Results: Regarding expression of cytokines, 23% were positive for IL-2, 26.7% for IL-4, 16.6% for IL-10 and none for TGF-β. There were found Significant statistically stage differences were noted.For example, for stages I-II 100% were IL-2 positive (p = 0.009), 87.5% were IL-4 positive (p = 0.005) and 100.0% IL-10 positive (p = 0.009). Young women were more likely to suffer gastric adenocarcinoma. In biopsies of male patients with gastric cancer, there was an increased expression of IL-2 and in biopsies from female patients in IL4. There was significantly greater detection of IL-4 and IL-10 expression in stages I and II than in stages III and IV. It was also found that IL-4, IL-10 had a higher positive expression in patients biopsies with low-level differentiations than patients with well differentiated gastric cancer in which cases were undetected. Conclusions: These results suggest that positive expression of IL-4 and IL-10 may be useful as a molecular marker to distinguish stage I and II diffuse gastric cancers which can be more readily controlled.

Lister strain vaccinia virus with thymidine kinase gene deletion is a tractable platform for development of a new generation of oncolytic virus. Gene Ther 2015; 22:476-84.

Abstract
Vaccinia virus (VV) has many attractive characteristics as a potential cancer therapeutic. There are several strains of VV. The nonvaccine strain Western Reserve VV with deletion of both the thymidine kinase and the viral growth factor genes (known as WRDD) has been reported as the most potent tumor-targeted oncolytic VV. Other strains, such as the European vaccine Lister strain, are largely untested. This study evaluated the antitumor potency and biodistribution of different VV strains using in vitro and in vivo models of cancer. Lister strain virus with thymidine kinase gene deletion (VVΔTK) demonstrated superior antitumor potency and cancer-selective replication in vitro and in vivo, compared with WRDD, especially in human cancer cell lines and immune-competent hosts. Further investigation of functional mechanisms revealed that Lister VVΔTK presented favorable viral biodistribution within the tumors, with lower levels of proinflammatory cytokines compared with WRDD, suggesting that Lister strain may induce a diminished host inflammatory response. This study indicates that the Lister strain VVΔTK may be a particularly promising VV strain for the development of the next generation of tumor-targeted oncolytic therapeutics.

Abstract
PURPOSE Vaccinia virus has strong potential as a novel therapeutic agent for treatment of pancreatic cancer. We investigated whether arming vaccinia virus with interleukin-10 (IL10) could enhance the antitumor efficacy with the view that IL10 might dampen the host immunity to the virus, increasing viral persistence, thus maximizing the oncolytic effect and antitumor immunity associated with vaccinia virus. EXPERIMENTAL DESIGN The antitumor efficacy of IL10-armed vaccinia virus (VVLΔTK-IL10) and control VVΔTK was assessed in pancreatic cancer cell lines, mice bearing subcutaneous pancreatic cancer tumors and a pancreatic cancer transgenic mouse model. Viral persistence within the tumors was examined and immune depletion experiments as well as immunophenotyping of splenocytes were carried out to dissect the functional mechanisms associated with the viral efficacy. RESULTS Compared with unarmed VVLΔTK, VVLΔTK-IL10 had a similar level of cytotoxicity and replication in vitro in murine pancreatic cancer cell lines, but rendered a superior antitumor efficacy in the subcutaneous pancreatic cancer model and a K-ras-p53 mutant-transgenic pancreatic cancer model after systemic delivery, with induction of long-term antitumor immunity. The antitumor efficacy of VVLΔTK-IL10 was dependent on CD4(+) and CD8(+), but not NK cells. Clearance of VVLΔTK-IL10 was reduced at early time points compared with the control virus. Treatment with VVLΔTK-IL10 resulted in a reduction in virus-specific, but not tumor-specific CD8(+) cells compared with VVLΔTK. CONCLUSIONS These results suggest that VVLΔTK-IL10 has strong potential as an antitumor therapeutic for pancreatic cancer.

Abstract
Cachexia, a negative prognostic factor, worsens a patient's quality of life. We established 2 novel cachexia models with the human stomach cancer cell line MKN-45, which was subcloned to produce potent cachexia-inducing cells by repeating the xenografts in immune-deficient mice. After subsequent xenografts, we isolated potent cachexia-inducing cells (MKN45cl85 and 85As2mLuc). Xenografts of MKN45cl85 cells in mice led to substantial weight loss and reduced adipose tissue and musculature volumes, whereas xenografts of 85As2mLuc cells resulted in highly metastatic and cachectic mice. Surgical removal of tumor tissues helped the mice regain body-weight in both mouse models. In vitro studies using these cells showed that isoflavones reduced their proliferation, implying that the isoflavones possess antiproliferative effects of these cancer cell lines. Isoflavone treatment on the models induced tumor cytostasis, attenuation of cachexia, and prolonged survival whereas discontinuation of the treatment resulted in progressive tumor growth and weight loss. The inhibitory effects of tumor growth and weight loss by isoflavones were graded as soy isoflavone aglycone AglyMax > daidzein > genistein. These results demonstrated that the 2 novel cachectic mouse models appear useful for analyzing the mechanism of cancer cachexia and monitoring the efficacy of anticachectic agents.

Abstract
While stem cell transplantation could potentially treat a variety of disorders, clinical studies have not yet demonstrated conclusive benefits. This may be partly because transplanted stem cells have low survival rates, potentially due to host inflammation. The system described herein used two different gene therapy techniques to improve retention of rat mesenchymal stem cells. In the first, stem cells were transfected with interleukin-10 (IL-10) before being loaded into a collagen scaffold. In the second, unmodified stem cells were loaded into a collagen scaffold along with polymer-complexed IL-10 plasmids. The scaffolds were surgically implanted into the dorsum of syngeneic rats. At each endpoint, the scaffolds were explanted and cell retention, IL-10 level and inflammatory response were quantified. All treatment groups had statistically significant increases in cell retention after 7 days, but the group treated with 2 µg of IL-10 polyplexes had a significant improvement even at 21 days. This cell retention was associated with increased IL-10 and decreased levels of proinflammatory cytokines and apoptosis. The primary effect on the inflammatory response appeared to be on macrophage differentiation, encouraging the regulatory phenotype over the cytotoxic lineage. Improving cell survival may be an important step toward realization of the therapeutic potential of stem cells.

Abstract
BACKGROUND Recombinant vaccinia virus (rVV) strains expressing the immunomodulatory cholera toxin B subunit (CTB) fused to the autoantigen glutamic acid decarboxylase (GAD) or the immunosuppressive cytokine interleukin-10 (IL-10) were independently able to generate only low levels of immune suppression of type 1 diabetes mellitus (T1DM). Here we suggest that a vaccinia virus (VV)-mediated combination of CTB::GAD fusion and IL-10 proteins promises a effective and durable immunotherapeutic strategy for T1DM. METHODS To explore this hypothesis, a CTB::GAD fusion gene was co-delivered with a gene encoding IL-10 by rVV infection (rVV-CTB::GAD + rVV-IL10) into 5-7-week-old non-obese diabetic (NOD) mice. The mice were assessed for vaccine protection against development of hyperglycemia from 12 to 64 weeks of age by assessment of pancreatic inflammation (insulitis) and splenocyte-secreted interferon-gamma and IL-10 cytokine levels. RESULTS By 36 weeks of age, from 54% to 80% of the mice in the negative control animal groups (either mock-infected or inoculated with unrelated plasmid or VV) had developed hyperglycemia. Similarly, no statistically significant improvement in protection against diabetes onset was achieved by inoculation with VV expressing CTB::GAD or IL-10 independently. Surprisingly, only 20% of mice co-inoculated with rVV-CTB::GAD + rVV-IL10 developed hyperglycemia by 28 weeks of age. Other treatment groups developed hyperglycemia by 32-36 weeks. After 36 weeks, diabetes incidence no longer increased in any groups until the end of experiment at 64 weeks of age. Histological analysis of pancreatic tissues of hyperglycemic mice revealed high levels of intra-islet insulitis. Analysis of insulitis at termination of the experiment showed that euglycemic mice co-inoculated with VV expressing CTB::GAD and IL-10 had more effectively reduced inflammation in comparison with the other groups. CONCLUSIONS A combinatorial vaccination strategy based on VV co-delivery of genes encoding the immunoenhanced autoantigen CTB::GAD and the anti-inflammatory cytokine IL-10 can maintain effective and durable euglycemia and immunological homeostasis in NOD mice with prediabetes.

Abstract
Vascular endothelial growth factor A (VEGF) is critical for vascular remodelling during tissue repair subsequent to inflammation or injury, but under pathological conditions, VEGF induces tissue damaging angiogenesis. Macrophages generate VEGF that supports angiogenesis, when they adapt to their environment and respond with a co-ordinated set of signals to promote or resolve inflammation. Depending on the stimulus, the phenotype of macrophage activation is broadly classified into M1 (NOS2(+)) and M2 (arginase-1(+)). In recent studies, IL-10, an anti-inflammatory cytokine that suppresses the M1 phenotype, has been shown to dampen the angiogenic switch and subsequent neovascularisation. However, as we show here, these effects are context dependent. In this study, we have demonstrated that IL-10 inhibits M1 bone marrow-derived macrophages (BMDMs) VEGF, stimulated by LPS/CGS21680 (adenosine A2A receptor agonist), but does not prevent VEGF production from M2 macrophages stimulated with prostaglandin E2 (PGE2). Furthermore, we show that hypoxic-conditioned BMDM generated VEGF was maintained in the presence of IL-10, but was suppressed when concomitantly stimulated with IFN-gamma. Finally, LPS/PGE2 generated an arginase-1(+) M2 macrophage that in addition to generating VEGF produced significant quantities of IL-10. Under these conditions, neither in IL-10 deficient macrophages nor following IL-10 neutralization was VEGF production affected. Our results indicate IL-10 suppressed M1 but not M2 derived VEGF, and that activation signals determined the influence of IL-10 on VEGF production. Consequently, therapies to suppress macrophage activation that as a result generate IL-10, or utilising IL-10 as a potential anti-angiogenic therapy, may result in a paradoxical support of neovascularisation and thus on-going tissue damage or aberrant repair.

Abstract
BACKGROUND Peritoneal dissemination of gastric cancer is often refractory to systemic therapies. Although adenoviral gene therapy has been reported to be a potentially useful therapeutic modality, the adenovirus itself has a dose-limiting toxicity. A novel system was constructed using adenoviral oncolytic suicide gene therapy targeting carcinoembryonic antigen (CEA), and its therapeutic effect and the possibility to reduce the total viral dose while still preserving the antitumor effect were assessed. METHODS Three types of adenoviruses were prepared for this novel system: (A) Ad/CEA-Cre, (B) Ad/lox-CD::UPRT for a Cre/loxP system, and (C) Ad/CEA-E1 for conditionally replicating adenovirus. The antitumor effect of the oncolytic suicide gene therapy (A + B + C) was then evaluated in vitro. Mice bearing peritoneal dissemination of human gastric cancer were treated with either this system (A + B + C) or with a tenfold viral dose of suicide gene therapy (A + B). The adverse effects in terms of hepatotoxicity were then evaluated between the two groups. RESULTS The current system (A + B + C) demonstrated significantly better cytotoxic effect for CEA-producing cell lines than did suicide gene therapy (A + B) at the same viral dose in vitro. The effect of oncolytic suicide gene therapy was almost equal to that of the tenfold viral dose of suicide gene therapy in vivo. The hepatotoxicity of the two treated groups was also found to be equivalent. CONCLUSION It was possible to reduce the total adenoviral dose of oncolytic suicide gene therapy while still preserving the antitumor effect.

Abstract
PURPOSE OF REVIEW Cancer anorexia-cachexia refers to a debilitating state of cancer patients, the pathogenesis of which is still fully unknown. The article reviews recent research into the role of inflammatory mediators and cytokine gene polymorphisms in the pathogenesis of cancer cachexia. RECENT FINDINGS Using transgenic mice, recent studies demonstrate that inflammatory mediators play an important role in the cancer cachexia development. Preliminary association studies in unrelated individuals exhibit that cytokine gene polymorphisms are related to cancer cachexia susceptibility. SUMMARY Although its pathogenesis is not fully known, inflammatory mediators have been involved in cancer cachexia. Single-nucleotide polymorphisms in genes coding inflammatory cytokines are likely to have played some role in cancer susceptibility. It is of great essentiality to further probe cancer cachexia-anorexia.

Abstract
BACKGROUND The genetic predisposition of the host to local or systemic inflammation may contribute to the effect of cancer cachexia. OBJECTIVE We investigated the relation between cytokine polymorphisms (IL1B -511, IL6 -174, IL10 -1082, TNFA -308, and LTA +252) and markers of nutritional status among patients with gastroesophageal cancer to determine whether any such association was reflected by cytokine concentrations in the tumor or plasma compartments. DESIGN Patients (n = 203) with a diagnosis of gastroesophageal cancer underwent nutritional assessment (body mass index, anthropometric measures, dysphagia scoring, and estimation of dietary intake). Single nucleotide polymorphism genotyping was performed by TaqMan allelic discrimination genotyping. Serum cytokine and C-reactive protein concentrations were determined by enzyme-linked immunosorbent assay. Tumor tissue cytokine protein concentrations (n = 56) were determined by using the Cytometric Bead Array System. RESULTS IL10 GG and IL6 CC polymorphisms were associated with elevated serum C-reactive protein concentrations, and the IL6 CC genotype was also associated with elevated tumor tissue cytokine concentrations. At diagnosis, the IL10 GG, but not the IL6, genotype was linked with increased total weight loss: 4.9% for AA, 7.1% for AG, and 12.0% for GG (P = 0.007). Serum C-reactive protein concentrations correlated with increased weight loss (r = 0.24, P < 0.001). Compared with other genotypes, the IL10 GG genotype retained an independent association in determining the extent of weight loss on multivariate analysis (95% CI: 0.52, 3.43; P = 0.008). Possession of the GG allele was associated with a 2.3 times increased risk of developing cachexia (95% CI: 1.2, 4.3; P = 0.014). CONCLUSION These data suggest that the IL10 genotype of the host can influence the development of cachexia among patients with gastroesophageal malignancy.

Abstract
PURPOSE OF REVIEW To review current knowledge of the relationship between cytokines, the acute phase response (APR) and the development of cachexia. RECENT FINDINGS Cytokines important in the initiation of the APR are also important in the genesis of cachexia. The presence of an APR or high circulating levels of pro-inflammatory cytokines are known to be related to adverse outcome in cancer patients. Studies of host cytokine genotype have demonstrated that specific host cytokine polymorphisms are associated with both the development of cachexia and reduced patient survival. The desire to be able to predict accurately survival in cancer patients has led to the description of various APR-based prognostic scoring systems. SUMMARY Cachexia is an important clinical problem affecting up to two thirds of cancer patients. It results from anorexia and metabolic change and leads to loss of both adipose tissue and lean body mass, particularly in the skeletal muscle compartment. An APR is seen in half of cancer patients at presentation, and is most often determined clinically by raised plasma C-reactive protein concentrations. Adverse outcome and shortened survival have been linked to the presence of an APR. This article explores the cause and consequences of the APR in cancer cachexia.

Abstract
BACKGROUND We recently demonstrated that a CO(2) pneumoperitoneum at either a high or low IPP has few if any short term effects on peritoneal dissemination when tumors are well established before surgery. The objective of the present study was to evaluate the impact of the surgical peritoneal environment on pre-implanted tumors on a molecular level. MATERIALS AND METHODS On day 7, C57BJ6 mice received an intraperitoneal inoculation of a mouse ovarian cancer cell line (ID8). On day 0, mice were randomized into four groups: anesthesia alone, CO(2) pneumoperitoneum at a low (2 mm Hg) or high (8 mm Hg) IPP, or laparotomy. Groups were further subdivided into four groups and a laparotomy was performed to collect pre-implanted tumors on POD 1, 2, 7, or 14. Expression levels of beta-1 integrin, cMet, uPA, uPAR, and PAI-1 mRNA in pre-implanted nodules were measured using real-time PCR. RESULTS Expression levels of uPA, uPAR, and cMet mRNA were significantly higher in the laparotomy group than in the control group on POD 1. We detected significantly higher expression levels of uPAR and cMet in the laparotomy group than in the control group on PODs 2 and 7. There were no significant differences in the expression levels of any genes examined among the low IPP, anesthesia alone, and control groups on POD 1, 2, 7, or 14. CONCLUSION The impact of a CO(2) pneumoperitoneum at a low IPP on gene expression levels of pre-implanted tumors might be minimal until POD 14 in the present mouse model.

Abstract
As a component of tumor stroma, tumor angiogenesis is not only essential to primary tumor growth but also one of the requisites to disseminate. Ultrastructural organization and immunohistochemisty have shown that density and quantity of blood vessels has a close association with the potentiality of tumor invasion and metastasis. Some recent studies confirm correlation between angiogenesis and invasion of gastric tumor, and some other studies prove that antiangiogenesis can significantly inhibit tumor growth and metastasis, which has demonstrated a promising application perspective for gastric carcinoma treatment.
