background and aims: inhibition of viral growth in coinfected cells with two different viruses has been described. this phenomenon known as viral interference can occur in several virus host systems such as interference of enterovirus infection on poliovirus vaccine strains. in this study we superinfected reovirus infected hela cells with poliovirus to determine if poliovirus can replicate in s...

Abstract : Reovirus (respiratory enteric orphan virus), a naturally occurring benign human pathogen, has an inherent ability to target transformed and cancerous cells and cause their lysis, while leaving non-transformed cells relatively unaffected. The efficiency of this innate oncolytic activity of reovirus correlates with expression of the ras oncogene. Cells expressing ac...
Oncolytic reovirus induces innate immune responses, which contribute to the antitumor activity of reovirus, following in vivo application. Reovirus-induced innate immune responses have been relatively well characterized in immune cells and mouse embryonic fibroblasts cells; however, the mechanisms and profiles of reovirus-induced innate immune responses in human tumor cells have not been well u...
Background and Aims: Oncolytic reoviruses can infect and kill malignant cells while sparing their normal counterparts. Reoviral infection can induce or activate autophagy, even though metformin can induce autophagy. Identifying and regulating the cellular pathways important for reovirus replication and oncolysis can improve targeted-biological therapies for cancer. Here, the autophagic process ...

PURPOSE Human reovirus type 3 has been proposed to kill cancer cells with an activated Ras signaling pathway. The purpose of this study was to investigate the efficacy of reovirus in immunocompetent glioma animal models and safety/toxicity in immunocompetent animals, including nonhuman primates. EXPERIMENTAL DESIGN Racine glioma cells 9L and RG2 were implanted s.c. or intracranially in Fisher...
Background: Avian reovirus (ARV) has a global distribution in nature and most clinical signs are found in broiler type chickens. Aims: This study was conducted to detect and identify reovirus infections from vaccinated breeder chickens and their progenies. Methods: A total of 20 tissue and blood samples were collected from vaccinated broiler br...
Mammalian reovirus is a benign virus that possesses the natural ability to preferentially infect and kill cancer cells (reovirus oncolysis). Reovirus exploits aberrant Ras signalling in many human cancers to promote its own replication and spread. In vitro and in vivo studies using reovirus either singly or in combination with anti-cancer drugs have shown very encouraging results. Presently, a ...
The usage of reovirus has reached phase II and III clinical trials in human cancers. However, this is the first study to report the oncolytic effects of reovirus in veterinary oncology, focusing on canine mast cell tumor (MCT), the most common cutaneous tumor in dogs. As human and canine cancers share many similarities, we hypothesized that the oncolytic effects of reovirus can be exploited in ...
