| Abstract |
Newcastle disease virus (NDV), a bird paramyxovirus, is an antitumor agent which has shown benefits to cancer patients. Its antineoplastic efficacy appears to be associated with three properties of the virus: 1. Selective replication in tumor cells. This feature can be studied at the RNA level, for example by RT-PCR, and at the protein level by immunochemistry. 2. Oncolytic properties (of some strains). The use of cultures of tumor cell lines represents a selective model to study direct viral oncolysis at the cellular level. The capacity of NDV to lyse tumor cells can be analyzed in vitro using cytotoxic assays based on the WST1 chemical reagent. The endoplasmic reticulum stress, which is induced by infection with the oncolytic NDV strain MTH-68/H and which plays an important role in the viral oncolytic effects, can be analyzed by Western blotting using specific monoclonal antibodies. Such stress appears as a key component of NDV cytotoxicity. 3. Immunostimulatory capacity. We describe an in vitro test called "Tumor Neutralisation Assay" which allows the analysis of bystander antitumor immune effects induced in human peripheral blood mononuclear cells by NDV. There are two variants, one for oncolytic NDV strains and the other one for nonlytic NDV strains. NDV may use several mechanisms to exert its tumor-killing action: direct cytotoxicity against cancer cells but also nonspecific as well as active-specific antitumor immune responses from the host organism. All the methods described here allow to evaluate the different oncolytic and immunostimulatory capacities of various strains of NDV. They are crucial to harness optimal antitumor activity by appropriate combinations of virus strains and application regimens. |
