Correspondence: Z Sheng Guo University of Pittsburgh Cancer Institute, 5117 Centre Avenue, Suite 1.46, Pittsburgh, PA 15213, USA Tel +1 412 623 7711 Fax +1 412 623 7709 Email [email protected] Abstract: The hypoxic tumor microenvironment plays significant roles in tumor cell metabolism and survival, tumor growth, and progression. Hypoxia modulates target genes in target cells mainly through an oxy...
Tumor-targeted replicating viruses are being developed as a novel class of oncolytic agents. Vesicular stomatitis virus (VSV) is a negative-strand RNA virus with inherent specificity for replication in tumor cells due to their attenuated antiviral responses. VSV as an oncolytic virus is particularly appealing for its exceptionally rapid replication rate in tumor cells, such that the oncolytic e...
Oncolytic virus (OV) is a kind of that can preferentially infect and kill tumor cells. The second oncolytic drug was herpes simplex (oHSV) Talimogene Laherparepvec (T-VEC). HSV-1 infectious cell culture protein 34.5 (ICP34.5) latency-associated transcript (LAT) genes are closely related to selective infection latent infection. Their engineering essential for constructing efficient safe oHSV. We...
Newcastle disease virus (NDV) is a single-stranded, negative-sense RNA virus in the Paramyxoviridae family. Although primarily an avian pathogen, NDV is a potent oncolytic virus that has been shown to be safe and effective in a variety of preclinical cancer models and human clinical trials. To produce virus for oncolytic trials, NDV is commonly amplified in embryonated chicken eggs and purified...
Mumps virus belongs to the family of Paramyxoviridae and has the potential to be an oncolytic agent. Mumps virus Urabe strain had been tested in the clinical setting as a treatment for human cancer four decades ago in Japan. These clinical studies demonstrated that mumps virus could be a promising cancer therapeutic agent that showed significant antitumor activity against various types of cance...
Vesicular stomatitis virus (VSV) is a promising oncolytic agent against a variety of cancers. However, it has never been tested in any pancreatic cancer model. Pancreatic ductal adenocarcinoma (PDA) is the most common and aggressive form of pancreatic cancer. In this study, the oncolytic potentials of several VSV variants were analyzed in a panel of 13 clinically relevant human PDA cell lines a...
Many drugs have been developed and optimized for the treatment of cancer; however, it is difficult to completely cure cancer with anticancer drugs alone. Therefore, the development of new therapeutic technologies, in addition to new anticancer drugs, is necessary for more effective oncotherapy. Oncolytic viruses are one potential new anticancer strategy. Various oncolytic viruses have been deve...
Oncolytic virotherapy is a treatment modality that uses native or genetically modified viruses that selectively replicate in and kill tumor cells. Viruses represent a type of pathogen-associated molecular pattern and thereby induce the up-regulation of dozens of cytokines via activating the host innate immune system. Second mitochondria-derived activator of caspases (Smac) mimetic compounds (SM...
Conditionally replicating (oncolytic) viruses, which selectively replicate in tumor cells but not in normal cells, show great promise as antitumor agents for cancer therapy. The principal antitumor activity of these viruses derives from their replication within tumor cells, which results in cell destruction and the production of progeny virions that can spread to adjacent tumor cells. However, ...
background: autophagy suppression recently has been known to have a remarkable effect for cellular adjustment and viability in the final stages of cancer. on the other hand, autophagy has the potential effect in preventing many viruses from replication. beclin1 is the most substantial constituent in autophagy apparatus regulation. this study was intended to investigate the beclin1 sirna knockdo...
