Abstract
Malignant tumors pose a grave threat to the quality of human life. The prevalence of malignant tumors in China is steadily rising. Presently, clinical interventions encompass surgery, radiotherapy, and pharmaceutical therapy in isolation or combination. Nonetheless, these modalities fail to completely eradicate malignant tumor cells, frequently leading to metastasis and recurrence. Conversely, tumor biotherapy has emerged as an encouraging fourth approach in preventing and managing malignant tumors owing to its safety, efficacy, and minimal adverse effects. Currently, a range of tumor biotherapy techniques are employed, including gene therapy, tumor vaccines, monoclonal antibody therapy, cancer stem cell therapy, cytokine therapy, and adoptive cellular immunotherapy. This study aims to comprehensively review the latest developments in biological treatments for malignant tumors.

Review of Experimental Studies to Improve Radiotherapy Response in Bladder Cancer: Comments and Perspectives. Cancers (Basel) 2020; 13:cancers13010087. [PMID: 33396795 PMCID: PMC7795454 DOI: 10.3390/cancers13010087] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 12/22/2020] [Accepted: 12/22/2020] [Indexed: 01/04/2023] Open
Abstract
Bladder cancer is among the top ten most common cancer types in the world. Around 25% of all cases are muscle-invasive bladder cancer, for which the gold standard treatment in the absence of metastasis is the cystectomy. In recent years, trimodality treatment associating maximal transurethral resection and radiotherapy combined with concurrent chemotherapy is increasingly used as an organ-preserving alternative. However, the use of this treatment is still limited by the lack of biomarkers predicting tumour response and by a lack of targeted radiosensitising drugs that can improve the therapeutic index, especially by limiting side effects such as bladder fibrosis. In order to improve the bladder-preserving treatment, experimental studies addressing these main issues ought to be considered (both in vitro and in vivo studies). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic reviews, we conducted a literature search in PubMed on experimental studies investigating how to improve bladder cancer radiotherapy with different radiosensitising agents using a comprehensive search string. We made comments on experimental model selection, experimental design and results, formulating the gaps of knowledge still existing: such as the lack of reliable predictive biomarkers of tumour response to chemoradiation according to the molecular tumour subtype and lack of efficient radiosensitising agents specifically targeting bladder tumour cells. We provided guidance to improve forthcoming studies, such as taking into account molecular characteristics of the preclinical models and highlighted the value of using patient-derived xenografts as well as syngeneic models. Finally, this review could be a useful tool to set up new radiation-based combined treatments with an improved therapeutic index that is needed for bladder preservation.

Abstract
To confirm the anti-tumor effect of engineered neural stem cells (NSCs) expressing cytosine deaminase (CD) and interferon-β (IFN-β) with prodrug 5-fluorocytosine (FC), K562 chronic myeloid leukemia (CML) cells were co-cultured with the neural stem cell lines HB1.F3.CD and HB1.F3.CD.IFN-β in 5-FC containing media. A significant decrease in the viability of K562 cells was observed by the treatment of the NSC lines, HB1.F3.CD and HB1.F3.CD.IFN-β, compared with the control. A modified trans-well assay showed that engineered human NSCs significantly migrated toward K562 CML cells more than human normal lung cells. In addition, the important chemoattractant factors involved in the specific migration ability of stem cells were found to be expressed in K562 CML cells. In a xenograft mouse model, NSC treatments via subcutaneous and intravenous injections resulted in significant inhibitions of tumor mass growth and extended survival dates of the mice. Taken together, these results suggest that gene therapy using genetically engineered stem cells expressing CD and IFN-β may be effective for treating CML in these mouse models.

Abstract
Radiotherapy (RT) is a well established modality for treating many forms of cancer. However, despite many improvements in treatment planning and delivery, the total radiation dose is often too low for tumor cure, because of the risk of normal tissue damage. Gene therapy provides a new adjunctive strategy to enhance the effectiveness of RT, offering the potential for preferential killing of cancer cells and sparing of normal tissues. This specificity can be achieved at several levels including restricted vector delivery, transcriptional targeting and specificity of the transgene product. This review will focus on those gene therapy strategies that are currently being evaluated in combination with RT, including the use of radiation sensitive promoters to control the timing and location of gene expression specifically within tumors. Therapeutic transgenes chosen for their radiosensitizing properties will also be reviewed, these include: gene correction therapy, in which normal copies of genes responsible for radiation-induced apoptosis are transfected to compensate for the deletions or mutated variants in tumor cells (p53 is the most widely studied example). enzymes that synergize the radiation effect, by generation of a toxic species from endogenous precursors ( e.g., inducible nitric oxide synthase) or by activation of non toxic prodrugs to toxic species ( e.g., herpes simplex virus thymidine kinase/ganciclovir) within the target tissue. conditionally replicating oncolytic adenoviruses that synergize the radiation effect. membrane transport proteins ( e.g., sodium iodide symporter) to facilitate uptake of cytotoxic radionuclides. The evidence indicates that many of these approaches are successful for augmenting radiation induced tumor cell killing with clinical trials currently underway.

Abstract
Bladder cancer is the second most common urological malignancy with a one in 28 lifetime risk. Three-quarters of tumors are non-muscle-invasive (formerly termed superficial) at the time of presentation. Approximately half of all non-muscle-invasive bladder cancer (NMIBC) will recur and, depending on certain prognostic factors including grade, stage and presence of carcinoma in situ, a number will progress to muscle invasion. The standard of care for NMIBC is transurethral resection of bladder tumor (TURBT) to remove the mass lesion(s). Intravesical therapy of NMIBC post-TURBT therefore aims to delay/prevent recurrence and/or progression to muscle-invasive bladder cancer. While intravesical chemotherapy, such as mitomycin C, and immunotherapy, such as bacillus Calmette-Guérin are well established, there is current interest in novel therapies based on improved molecular understanding of bladder cancer. These novel therapies include gene therapy, using viral and non-viral vectors for transfer, monoclonal antibodies and direct tumoricidal viruses. While there is a sound theoretical basis for these therapies based on molecular targeting, there is little evidence in human studies that these therapies have clinical impact on NMIBC. However, it is certain that their use will be investigated further and they provide great hope for the future of NMIBC adjuvant therapy.

Abstract
AIM: To study in vitro therapeutic effect on mouse pancreatic cancer, as well as the bystander effect with HSV-TK suicide gene in combination with prodrug GCV.
METHODS: HSV-TK and GFP were inserted into pcDNA3.1 (+) to construct pcDNA3.1+/HSV-TK+GFP, and pcDNA3.1+/HSV-TK+GFP was transferred into mouse pancreatic cancer cell MPC by Lipofectin. We then added GCV to these gene-modified cells and studied the sensitivity of the cells to GCV as well as the bystander effect.
RESULTS: The gene modified pancreatic cancer cells MPC/HSV-TK+GFP were successfully developed. In vitro experiments showed that when the MPC/HSV-TK+GFP cells accounted for 10% of hybrid cells, the low concentration (20 mg/L) of GCV was about 50% of tumor cell killing. In vivo results showed that the low concentration of GCV killed the cells. And tumor growth of the mouse model was inhibited.
CONCLUSION: Our data demonstrate MPC/HSV-TK+GFP cells are sensitive to the treatment of GCV compared with unmodified tumor cells, and remarkable bystander effect is seen.

Abstract
BACKGROUND Painful breast carcinoma metastases in bone are a common manifestation of malignant disease. Eradication of these tumors can be evasive, and as a result, skeletal morbidity increases with disease progression. EXPERIMENTAL DESIGN The treatment potential of cytosine deaminase (CD) gene therapy combined with radiation treatment was evaluated in vitro and in vivo using a 4T1 murine breast carcinoma model. 4T1 carcinoma cells were transduced with a fusion gene encoding the extracellular and transmembrane domains of the human nerve growth factor receptor and the cytoplasmic portion of the yeast CD gene (NGFR-CD(y)). RESULTS AND CONCLUSIONS CD-expressing tumor cells (4TCD(y)) were highly sensitive to treatment by 5-fluorocytosine prodrug (P < 0.0001). 5-Fluorocytosine treatment of 4TCD(y), but not 4T1 cells, enhanced the effects of radiation in vitro (P < 0.0001). 5-Fluorocytosine prodrug treatment also increased the therapeutic potential of radiation in vivo. Mice with 4TCD(y) intrafemoral tumors showed increased effectiveness of radiation based on improved reductions in tumor size, reductions in tumorigenic osteolysis, and a decrease in skeletal fractures (P < 0.01).

Abstract
Cancer is a disease of high incidence for which conventional treatments are not necessarily effective. There is a need for the development of new alternative strategies. Among them, suicide gene therapy has been developed. In this approach, a gene encoding for a protein toxic under particular conditions is delivered to the target cells, resulting in their death. Although this approach has been in development for a long time, new combinations with other gene therapy areas, such as selective replicative viruses, tumour targeting, or conventional treatments such as chemo- or radiotherapy, are currently being tested. This review will summarise some of these approaches.
