RIPK3 and non-small cell lung carcinoma: Similar to our rVSV results, we could not identify a molecular mediator determining the switch from apoptosis to necroptosis after rVSV-NDV infection, but we did observe moderate levels of RIPK1, RIPK3, and MLKL expression and phosphorylation in rVSV-NDV-infected NSCLC cells, indicative of syncytial necroptosis as an oncolytic alternative to apoptosis.
