Intraperitoneal therapy of ovarian cancer using an engineered measles virus.
The use of replicating viruses for cancer therapy (virotherapy) holds much promise. We reported previously that the live attenuated Edmonston B vaccine strain of measles virus (MV-Edm) had antineoplastic efficacy against hematological malignancies. In this study, we demonstrate that a recombinant MV-Edm, genetically engineered to express an inert soluble marker peptide (MV-hCEA), is potent agai...
متن کاملDeficiency of caspase 3 in tumor xenograft impairs therapeutic effect of measles virus Edmoston strain
The oncolytic measles virus Edmonston (MV-Edm) strain shows considerable oncolytic activity against a variety of human tumors. In this study, we report MV-Edm is able to trigger apoptosis pathways in infected tumor cells and elucidate the roles of cellular apoptosis in the whole oncolytic process. We also show that activated caspase 3, a key executioner of apoptosis, plays key roles in the onco...
متن کاملA molecularly cloned Schwarz strain of measles virus vaccine induces strong immune responses in macaques and transgenic mice.
Live attenuated RNA viruses make highly efficient vaccines. Among them, measles virus (MV) vaccine has been given to a very large number of children and has been shown to be highly efficacious and safe. Therefore, this vaccine might be a very promising vector to immunize children against both measles and other infectious agents, such as human immunodeficiency virus. A vector was previously deri...
متن کاملMitophagy switches cell death from apoptosis to necrosis in NSCLC cells treated with oncolytic measles virus
Although apoptotic phenomena have been observed in malignant cells infected by measles virus vaccine strain Edmonston B (MV-Edm), the precise oncolytic mechanisms are poorly defined. In this study we found that MV-Edm induced autophagy and sequestosome 1-mediated mitophagy leading to decreased cytochrome c release, which blocked the pro-apoptotic cascade in non-small cell lung cancer cells (NSC...
متن کاملConstruction of a Minigenome Rescue System for Measles Virus, AIK-c Strain
Background:In the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded RNA viruses from cDNA or viral minigenomes. This technique has been applied to study different steps in virus replication and virus-host interactions. Reverse genetics could also be implemented for design of new vaccines. The T7 RNA polymerase activity as well as virus (nucleocapsi...
