【 摘 要 】
References(33)Cited-By(1)Oncolytic virotherapy is a new strategy for cancer treatment for humans anddogs. Reovirus has been proven to be a potent oncolytic virus in human medicine. Ourlaboratory has previously reported that canine mast cell tumor and canine lymphoma weresusceptible to reovirus. In this study, canine solid tumor cell lines (mammary glandtumor, osteosarcoma and malignant melanoma) were tested to determine their susceptibilitytowards reovirus. We demonstrated that reovirus induces more than 50% cell death in threecanine mammary gland tumors and one canine malignant melanoma cell line. Thereovirus-induced cell death occurred via the activation of caspase 3. Ras activation hasbeen shown to be one of the important mechanisms of reovirus-susceptibility in humancancers. However, Ras activation was not related to the reovirus-susceptibility in caninesolid tumor cell lines, which was similar to reports in canine mast cell tumor and caninelymphoma. The results of this study highly suggest that canine mammary gland tumor andcanine malignant melanoma are also potential candidates for reovirus therapy in veterinaryoncology.
