Abstract
Aims:
Encouraging results have been indicated preclinically and in patients using the
bacterial superantigen. This review article intends to summarize the role of the superantigens that
have been recently used in the treatment of cancer. In addition, the vector systems, including lentiviral
vectors, adeno-associated vector systems and retroviral vectors that are increasingly being
used in basic and applied research, were discussed. Most importantly, the new CRISPR technique
has also been discussed in this literature review.
Discussion:
More successful therapies can be achieved by manipulating bacterial vector systems
through incorporating genes related to the superantigens and cytokines. The products of SAg and
cytokine genes contribute to the strong stimulation of the immune system against tumor cells. They
bind to MHC II molecules as well as the V beta regions of TCR and lead to the production of IL2
and other cytokines, the activation of antigen-presenting cells and T lymphocytes. Additionally, superantigens
can be used to eradicate tumor cells. Better results in cancer treatment can be achieved
by transferring superantigen genes and subsequent strong immune stimulation along with other cancer
immunotherapy agents.
Conclusion:
Superantigens induce the proliferation of T lymphocytes and antigen-presenting cells
by binding to MHCII molecules and V beta regions in T cell receptors. Therefore, the presentation
of tumor cell antigens is increased. Additionally, the production of important cytokines by T cells
and APCs contributes to the stimulation of immune response against tumor cells. The manipulation
of bacterial vector systems through incorporating genesrelated to SAgs and other immune response
factors is a good strategy for the immune system stimulating and eradicating tumor cells along with
other immunotherapy agents.

Abstract
The present study aimed to investigate the effects of Staphylococcus aureus enterotoxin C3 (SEC3), including recombinant (r)SEC3 protein and lentivirus‑mediated SEC3, on the activation, proliferation and cytokine production of human T cells. HeLa cells were infected with SEC3 lentiviral vector (LV‑SEC3) and viability was determined using the Cell Counting Kit‑8 (CCK‑8) assay. Subsequently, infected cells or rSEC3 protein were co‑cultured with human peripheral blood mononuclear cells (PBMCs) for 10 days, after which the culture supernatant and T cells were incubated with untreated HeLa cells, which were subjected to a CCK‑8 assay to determine cytotoxicity. In addition, IL‑6 and IFN‑γ expression was detected by chemiluminescence and enzyme‑linked immunospot analyses, respectively. Subpopulations of activated T cells were sorted by flow cytometry. The results demonstrated that, following infection with LV‑SEC3 or negative control lentiviral vector (LV‑NC), >80% of HeLa cells presented green fluorescent protein‑positive signals. All five groups of co‑cultured T cells exhibited proliferation. Co‑culture of PBMCs with rSEC3 protein or LV‑SEC‑infected cells resulted in elevated IL‑6 and IFN‑γ secretion. In addition, rSEC3‑activated and monocultured T cells were predominantly cluster of differentiation (CD)4+ (62.7 and 59.6%, respectively) whereas phytohemagglutinin‑stimulated T cells were predominantly CD8+ (57.8%). Compared with the LV‑NC group, T cells and culture supernatants from the LV‑SEC3 group significantly attenuated proliferation of HeLa cells. These results suggest that rSEC3 protein, and LV‑SEC3‑infected HeLa cells, are able to potently activate T cells, increasing cytokine production and amplify the antitumor immune response.

Abstract
Staphylococcus enterotoxin A (SEA) is a powerful immunostimulant and can stimulate T cells bearing certain T-cell receptor β-chain variable regions when bound to major histocompatibility complex II molecules. SEA is widely used in research of antitumor therapy. The low affinity T-cell receptor (TCR) interaction with SEA in the absence of MHC class II antigens is sufficient for the induction of cytotoxicity but requires additional CD28/B7 signaling to result in proliferation of resting T cells. In this study, we constructed recombinant adenovirus (named as Ad-MMRE-mTERT-BIS) carrying membrane-expressing SEA (named as SEAtm) and CD80 driven by Myc-Max response elements (MMRE) and mouse telomerase reverse transcriptase (mTERT) promoter to reduce toxicity and to improve safety and efficiency. We demonstrated that Ad-MMRE-mTERT-BIS could make SEAtm and CD80 to co-express highly on the surface of Hepa1-6 and B16 cells, at low level on the surface of CT26 cells, but not in NIH3T3. Hepa1-6 and B16 cells infected by the recombinant adenovirus induced proliferation of CD4+ and CD8+ T cells and increased cytokine [interleukin (IL)-2, tumor necrosis factor (TNF)-α, interferon (IFN)-γ] production in vitro. Intratumoral injection of Ad-MMRE-mTERT-BIS in hepatoma and melanoma mouse models induced tumor-specific cytotoxic T cells in the spleen. Moreover, hepatoma and melanoma xenografts were suppressed by treatment with Ad-MMRE-mTERT-BIS and the survival time of treated mice was prolonged. These findings suggest that recombinant adenovirus of SEA and CD80 genes driven by mTERT promoter could induce effective antitumor immune responses against different kinds of tumor cells in vitro and in vivo.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancer related deaths worldwide. One of the main challenges in cancer treatment is drug delivery to target cancer cells specifically. Preclinical evaluation of intratumoral drugs in orthotopic liver cancer mouse models is difficult, as percutaneous injection hardly can be precisely performed manually. In the present study we have characterized a hepatoma model developing a single tumor nodule by implantation of Hep55.1C cells in the liver of syngeneic C57BL/6J mice. Tumor evolution was followed up by µCT imaging, and at the histological and molecular levels. This orthotopic, poorly differentiated mouse HCC model expressing fibrosis, inflammation and cancer markers was used to assess the efficacy of drugs. We took advantage of the high precision of a previously developed robotized system for automated, image-guided intratumoral needle insertion, to administer every week in the tumor of the Hep55.1C mouse model. A significant tumor growth inhibition was observed using our robotized system, whereas manual intraperitoneal administration had no effect, by comparison to untreated control mice.

Abstract
This study aims to investigate effects of alpha-fetoprotein (AFP)-activated phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway on hepatocellular carcinoma cell proliferation. Active cirrhosis patients after hepatitis B infection (n = 20) and viral hepatitis patients with hepatocellular carcinoma (HCC) (n = 20) were selected as the subjects of the present study. Another 20 healthy subjects were selected as the control group. The serum AFP expression and liver tissue PI3K and Akt gene mRNA expression were detected. The hepatoma cell model HepG2 which had a stable expression of AFP gene was used. Real-time quantitative PCR and Western blot and other methods were used to analyze the intracellular PI3K and Akt protein levels. Compared with control group and cirrhosis group, the serum AFP levels in HCC group significantly increased, and the tissue PI3K and Akt mRNA expression also significantly increased. HepG2 cells were intervened using AFP, in which the PIK and Akt protein expression significantly increased. After intervention by use of AFP monoclonal antibodies or LY294002 inhibitor, the PIK and Akt protein expression in HepG2 cell was significantly decreased (P < 0.05). AFP can promote the proliferation of hepatoma cells via activation of PI3K/Akt signaling pathway.

Abstract
Hepatocellular carcinoma (HCC) is the 5th common malignancy worldwide, but established markers fail to detect up to one third of HCC. We have recently identified Neighbor of Punc E11 (Nope) as a surface marker for murine fetal liver stem cells. Similar to commonly used HCC markers such as α-Fetoprotein (Afp) and Glypican-3 (Gpc-3), we here establish Nope as an oncofetal marker of murine and human HCC and investigate its specific expression in hepatoma cell lines and primary HCC. Murine and human hepatoma cell lines and Cre-inducible SV40 T-antigen transgenic mice (Alb-SV40TAg(ind) ) were analyzed for Nope expression in comparison to common HCC markers by quantitative RT-PCR, Western blot analyses and immunohistochemistry. Nope expression in primary human HCC was investigated using Oncomine Microarray database. Nope expression was elevated in 8 of 10 investigated murine and human hepatoma cell lines and in all tumors of our oncogenic mouse model but remained undetectable in normal liver and at preneoplastic stages of murine hepatocarcinogenesis. Furthermore, a significant induction of Nope was detected in primary human cancers compared to corresponding normal or cirrhotic tissue. Nope expression in tumor specimens and murine cell lines correlated closely with expression levels of Gpc-3, whereas expression levels of Afp showed high variations. In conclusion, we identified Nope as a novel oncofetal surface marker for murine and human HCC. Nope is specifically expressed by epithelial tumor cells but not in preneoplastic stages and is a promising marker for clinical application because of its high detection rate in Afp-positive and Afp-negative tumors.

Abstract
Secreted and intracellular proteins including antibodies, cytokines, major histocompatibility complex molecules, antigens, and enzymes can be redirected to and anchored on the surface of mammalian cells to reveal novel functions and properties such as reducing systemic toxicity, altering the in vivo distribution of drugs and extending the range of useful drugs, creating novel, specific signaling receptors and reshaping protein immunogenicity. The present review highlights progress in designing vectors to target and retain chimeric proteins on the surface of mammalian cells. Comparison of chimeric proteins indicates that selection of the proper cytoplasmic domain and introduction of oligiosaccharides near the cell surface can dramatically enhance surface expression, especially for single-chain antibodies. We also describe progress and limitations of employing surface-tethered proteins for preferential activation of prodrugs at cancer cells, imaging gene expression in living animals, performing high-throughput screening, selectively activating immune cells in tumors, producing new adhesion molecules, creating local immune privileged sites, limiting the distribution of soluble factors such as cytokines, and enhancing polypeptide immunogenicity. Surface-anchored chimeric proteins represent a rich source for developing new techniques and creating novel therapeutics.

Abstract
Immunotherapy has been proposed as a therapeutic strategy in advanced-stage melanomas in which other therapeutic options have little effect. The Staphylococcus enterotoxin A (SEA) has been used to stimulate an antitumoral immune response but its use is hampered by severe systemic side effects. Here, we show that SEA can be targeted to melanoma cells to limit these side effects. More specifically, we used a nonviral vector, the cationic polymer, polyethylenimine (PEI), to express a transmembrane SEA fusion construct (pSEA-TM) in B16F10-induced subcutaneous melanoma in mice. The efficacy of this in vivo transfection was enhanced by concomitant infusion of epinephrine to induce local vasoconstriction. In these conditions, repeated injections of pSEA-TM/PEI complexes elicited a significant response, as evidenced by tumor growth inhibition, without systemic adverse effects. T cell infiltration of the tumors, together with positive lymphocyte proliferation tests, suggested local and systemic immune responses. Altogether, PEI-mediated targeting of SEA to melanoma tumor cells in vivo efficiently stimulates the antitumor immune response without inducing the side effects observed with systemic administration of SEA.
