Oncolytic vaccinia virus (VACV) therapy is an alternative treatment option for glioblastoma multiforme. Here, we used a comparison of different tumor locations and different immunologic and genetic backgrounds to determine the replication efficacy and oncolytic potential of the VACV LIVP 1.1.1, an attenuated wild-type isolate of the Lister strain, in murine GL261 glioma models. With this approa...
Since the 1990s, oncolytic viruses were utilized to treat cancer patients from phase I to phase III. Oncolytic virus development in China has been keeping in step with that in other countries and even accelerated the process in some fields, especially in conducting clinical trials. H101 is one kind of oncolytic adenovirus with E1B-55KD and partial E3 deleted developed by Shanghai Sunwaybio. Fro...
The development of oncolytic viruses has led to an emerging new class of cancer therapeutics. Although the safety profile has been encouraging, the transition of oncolytic viruses to the clinical setting has been a slow process due to modifications. Therefore, a new generation of more potent oncolytic viruses needs to be exploited, following our better understanding of the complex interactions ...
conclusions this study delineated the beneficial role of rsv for growth regulation of skin cancer cells and highlighted the involvement of rsv in the induction of apoptosis in a431 cells. these findings might conduct evidence into the oncolytic properties of rsv in the skin cancer. further studies are required to indicate intracellular targets for rsv-induced apoptosis in skin cancer cells. res...
Recombinant poxviruses, utilized as vaccine vectors and oncolytic viruses, often require manipulation at multiple genetic loci in the viral genome. It is essential for viral vectors to possess no adventitious mutations and no (antibiotic) selection marker in the final product for human patients in order to comply with the guidance from the regulatory agencies. Rintoul et al. have previously dev...
Oncolytic virus research got a welcome boost last November when Chinese regulators approved the world’s fi rst oncolytic viral therapy for cancer, Shanghai Sunway Biotech’s genetically modifi ed adenovirus H101. “ It’s fantastic for the fi eld, ” said John Bell , Ph.D., of the Ottawa Health Research Institute in Canada. “ We needed to have something that was a success, and so I think this is a ...
Replication-competent adenoviruses armed with thymidine kinase (TK) combine the concepts of virotherapy and suicide gene therapy. Moreover TK-activity can be detected by noninvasive positron emission-computed tomography (PET) imaging, what could potentially facilitate virus monitoring in vivo. Here, we report the generation of a novel oncolytic adenovirus that incorporates the Tat8-TK gene unde...
Emerging data suggest that locoregional cancer therapeutic approaches with oncolytic viruses can lead to systemic anti-tumour immunity, although the appropriate targets for intratumoral immunomodulation using this strategy are not known. Here we find that intratumoral therapy with Newcastle disease virus (NDV), in addition to the activation of innate immunity, upregulates the expression of T-ce...
New treatment approaches are needed for hormone refractory prostate cancer. Oncolytic adenoviruses are promising anti-cancer agents, and their efficacy can be improved by combining with conventional therapies such as ionizing radiation. The aim of this study was to determine the timing of oncolytic adenovirus treatment with regard to radiation and study the mechanisms of synergy in combination ...
Most of the oncolytic herpes simplex viruses (HSVs) exhibit a high safety profile achieved through attenuation. They carry defects in virulence proteins that antagonize host cell response to the virus, including innate response, apoptosis, authophagy, and depend on tumor cell proliferation. They grow robustly in cancer cells, provided that these are deficient in host cell responses, which is of...
